We are superseding Airworthiness Directive (AD) 2003-18-06, which applied to certain Airbus Model A319-131 and -132 airplanes; Model A320-231, -232, and -233 airplanes; and Model A321-131 and -231 airplanes. AD 2003-18-06 required installing new anti-swivel plates and weights on the engine fan cowl door (FCD) latches and a new cowl door hold-open device. This AD retains the previous actions and requires modifying the engine FCDs, installing placards, and re-identifying the FCDs. This AD also adds airplanes to the applicability. This AD was prompted by reports of additional engine FCD in-flight losses, and a new FCD front latch and keeper assembly that has been developed to address this unsafe condition. We are issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2003-18-06, 
which applied to certain Airbus Model A319-131 and -132 airplanes; 
Model A320-231, -232, and -233 airplanes; and Model A321-131 and -231 
airplanes. AD 2003-18-06 required installing new anti-swivel plates and 
weights on the engine fan cowl door (FCD) latches and a new cowl door 
hold-open device. This AD retains the previous actions and requires 
modifying the engine FCDs, installing placards, and re-identifying the 
FCDs. This AD also adds airplanes to the applicability. This AD was 
prompted by reports of additional engine FCD in-flight losses, and a 
new FCD front latch and keeper assembly that has been developed to 
address this unsafe condition. We are issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective August 3, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 3, 
2017.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2003-18-06, Amendment 39-13297 (68 FR 53501, 
September 11, 2003) (``AD 2003-18-06''). AD 2003-18-06 applied to 
certain Airbus Model A319-131 and -132 airplanes; Model A320-231, -232, 
and -233 airplanes; and Model A321-131 and -231 airplanes. The NPRM 
published in the Federal Register on August 5, 2016 (81 FR 51813). The 
NPRM was prompted by reports of additional engine FCD in-flight losses, 
and a new FCD front latch and keeper assembly that has been developed 
to address this unsafe condition. The NPRM proposed to continue to 
require installing new anti-swivel plates and weights on the engine FCD 
latches and a new cowl door hold-open device. The NPRM also proposed to 
require modifying the engine FCDs, installing placards, and re-
identifying the FCDs with new part numbers. Additionally, the NPRM 
proposed to revise the applicability to include all Model

[[Page 29372]]

A319-131 and -132 airplanes; Model A320-231, -232, and -233 airplanes; 
and Model A321-131 and -231 airplanes. We are issuing this AD to 
prevent in-flight loss of an engine FCD and possible consequent damage 
to the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0053, dated March 14, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A319-131 and -132 airplanes; Model A320-231, -232, and -233 airplanes; 
and Model A321-131 and -231 airplanes. The MCAI states:

    Fan Cowl Door (FCD) losses during take-off were reported on 
aeroplanes equipped with IAE V2500 engines. Prompted by these 
occurences, [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
DGAC France issued AD 2000-444-156(B), mandating FCD latch 
improvements. This [DGAC] AD was later superseded by [DGAC] AD 2001-
381(B) [which corresponds to FAA AD 2003-18-06], requiring 
installation of additional fan cowl latch improvement by installing 
a hold open device.
    Since that [DGAC] AD was issued, further FCD in flight losses 
were experienced in service. Investigations confirmed that in all 
cases, the fan cowls were opened prior to the flight and were not 
correctly re-secured. During the pre-flight inspection, it was then 
not detected that the FCD were not properly latched.
    This condition, if not corrected, could lead to in-flight loss 
of a FCD, possibly resulting in damage to the aeroplane and/or 
injury to persons on the ground.
    Prompted by these recent events, new FCD front latch and keeper 
assembly were developed, having a specific key necessary to un-latch 
the FCD. This key cannot be removed unless the FCD front latch is 
safely closed. The key, after removal, must be stowed in the flight 
deck at a specific location, as instructed in the applicable 
Aircraft Maintenance Manual. Applicable Flight Crew Operating Manual 
has been amended accordingly. After modification, the FCD is 
identified with a different Part Number (P/N).
    For the reasons described above, this [EASA] AD retains the 
requirements of DGAC AD 2001-381(B), which is superseded, and 
requires modification and re-identification of FCD.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
8185.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Request To Withdraw the NPRM

    United Airlines (UAL) stated that it strongly disagrees with making 
the new latch keys installation mandatory. UAL stated that each one of 
the fan cowl door losses during takeoff can be attributed solely to 
human error. UAL explained that the mechanics are not correctly 
latching the fan cowl after maintenance and the flight crews are not 
checking that the latches are secured before departure. UAL asserted 
that it did not believe that introduction of the new latch design would 
resolve human error problems. Historically, UAL noted, visual cues have 
proven ineffective, but other changes, especially dual inspection 
signoff, have proven much more effective. Therefore, instead of 
mandating the modification, UAL stated that more emphasis should be 
placed on addressing the root cause--not the design, but human error.
    Further, UAL explained that the fan cowls are routinely accessed 
for engine and thrust reverser maintenance, and adding another loose 
piece of equipment to be maintained and stored on the airplane would 
lead to operational complications. UAL also noted that additional time 
would be added to accomplishing routine tasks after incorporation of 
the modification. In a case where the maintenance personnel are 
required to open the fan cowls, UAL contended that additional time 
would be required to access the cockpit, retrieve the key, and open the 
fan cowls, which would expose personnel and the airplane to further 
damage or harm. Mandating the modification, UAL argued, would impose an 
unnecessary financial and maintenance burden on operators that have 
proactively implemented alternate procedures.
    UAL further stated that some airplanes in their Model A319 and 
Model A320 fleet are installed with monolithic FCDs which have some 
design advantages to mitigate the risks addressed in this AD. This AD 
does not include any modification instructions for these FCDs.
    From these statements, we infer that UAL was requesting that we 
withdraw the NPRM. We do not agree with UAL's request. The EASA, as the 
State of Design Authority for Airbus products, has determined an unsafe 
condition exists after conducting a risk analysis taking into 
consideration the in-service events in the worldwide fleet. We agree 
with EASA's decision to mitigate the risk by mandating a new design 
that makes it apparent to the flight crew on a pre-flight walk-around 
that an FCD is not latched. Regarding the concern about operational 
complications, we have determined that the safety benefits of the new 
design outweigh any potential complications. UAL has not provided any 
substantiating information to support withdrawing the NPRM. If an 
operator believes that there are certain FCDs that cannot be modified 
in accordance with the AD requirements, then they may apply for an 
alternative method of compliance (AMOC) using the procedures specified 
in paragraph (m)(1) of this AD. We have not revised this AD in this 
regard.

Requests To Allow Continued Operation With a Lost or Damaged Key/Lock

    UAL and American Airlines (AAL) requested that we add a provision 
in the proposed AD to allow continued operation with a damaged or 
missing key or damaged lock. UAL also stated that it disagrees with 
mandating the exact stowage location of the key and that it should be 
left to the operator's discretion where to store the key on the 
airplane. UAL pointed out that the key could become lost or damaged, 
and that it's possible the lock could become damaged, requiring the 
airplane to be taken out of service.
    We disagree with the commenters. EASA has determined that proper 
stowage for retrieval of the key and a fully functional lock are 
necessary to mitigate the risk of losing an FCD in flight, and we agree 
with EASA's assessment. If relief is approved in the future, such as 
Master Minimum Equipment List (MMEL) relief, that allows continued 
operation with a damaged or missing key or damaged lock, we will 
consider additional rulemaking. An operator may also apply for an AMOC 
using the procedures specified in paragraph (m)(1) of this AD, provided 
they submit sufficient data to substantiate that the AMOC provides an 
acceptable level of safety. We have not revised this AD in this regard.

Requests To Remove Placard Installation Requirement

    AAL requested that we revise the proposed AD to allow continued 
operation with a damaged or missing placard provided the placard is 
replaced within a specific time. AAL pointed out that a missing or 
damaged placard does not reduce flight safety. UAL also requested that 
the installation and location of the placard not be mandated. UAL 
explained that the placard itself does not prevent a fan cowl door loss 
event, nor does it raise awareness about the issue.

[[Page 29373]]

    We disagree with the commenters. Installation of the placard is 
designed to ensure that the key is stowed in a particular location on 
board the airplane and can be consistently retrieved from that location 
when needed. However, an operator may apply for an AMOC using the 
procedures specified in paragraph (m)(1) of this AD, provided they can 
show they have an alternative means to ensure the key is stowed on 
board the airplane in a constantly retrievable and accessible location. 
We have not revised this AD in this regard.

Request To Revise Cost Estimate

    AAL requested that we review the proposed cost estimate for 
significant economic impact as related to the actual costs of 
compliance. AAL asserted that the proposed cost estimate is 
underestimated and that the actual cost is nearly double the specified 
amount. AAL stated that two kits are required per airplane instead of 
the one kit estimated in the NPRM, and that the placard cost from 
Airbus is $50. AAL explained that the NPRM does not account for the 
cost of maintenance activities such as re-rigging all cowl latches 
during embodiment, or other recording, tracking, and supply chain 
costs. Additionally, AAL mentioned that U.S. operators are competing 
with operators worldwide for these parts, which could impact the 
availability of necessary parts.
    We partially agree with AAL's request. We recognize that, in 
accomplishing the requirements of any AD, operators might incur 
``incidental'' costs in addition to the ``direct'' costs that are 
reflected in the cost analysis presented in the AD preamble. However, 
the cost analysis in AD rulemaking actions typically does not include 
incidental costs. However, we have confirmed the need for two kits and 
the cost of the placards; therefore, we have revised this final rule to 
reflect the cost for two kits and placards.
    Regarding the reference to a ``significant economic impact,'' 
according to Executive Order 12866, we are not required to do a full 
cost-benefit analysis for an AD unless it is considered a significant 
regulatory action. This AD is not a significant regulatory action 
because it does not have an annual effect on the economy of $100 
million dollars or more; it does not create inconsistency with an 
action planned by another agency; it does not impact entitlements, 
grants, user fees or loan programs; and it does not raise novel legal 
or policy issues. However, the FAA does comply with Executive Order 
12866 by assessing the costs and determining that correcting the unsafe 
condition justifies them. As a matter of law, in order to be airworthy, 
an aircraft must conform to its type design and be in a condition for 
safe operation. The type design is approved only after we determine 
that it complies with all applicable airworthiness requirements. In 
adopting and maintaining those requirements, we have already determined 
that they establish a level of safety that is cost beneficial. When we 
later make a finding of an unsafe condition in an aircraft and issue an 
AD, it means that the original cost-beneficial level of safety is no 
longer being achieved and that the required actions are necessary to 
restore that level of safety. Because this level of safety has already 
been determined to be cost beneficial, and because the AD does not add 
any additional regulatory requirement that increases the level of 
safety beyond what has been established by the type design, a full 
cost-benefit analysis would be redundant and unnecessary. We have not 
revised this AD in this regard.

Request To Exempt Certain Airplanes

    Airbus requested that we revise the NPRM to exclude airplanes on 
which the following Airbus modifications were installed in production 
from the requirements of paragraph (g) of the proposed AD.
     Modifications 21948/P6222 and 30869.
     Modifications 24259/P6222 and 30869.
     Modifications 24259/P6222 and 24259/P6473.
    We agree with excluding airplanes with these Airbus modifications 
that were installed during production. These modifications address the 
identified unsafe condition. These exempt airplanes were inadvertently 
omitted from paragraph (g) of the proposed AD. We have revised 
paragraph (g) of this AD accordingly.

Request To Extend Compliance Time

    AAL requested that, due to the elapsed time needed to complete each 
airplane modification and the potential unavailability of modification 
kits to match the operator's modification schedule, we extend the 
compliance time for the new modification from 36 months to 48 months.
    We do not agree with AAL's request to extend the compliance time. 
In developing an appropriate compliance time for this action, we 
considered the urgency associated with the subject unsafe condition, 
the availability of required parts, and the practical aspect of 
accomplishing the required modification within a period of time that 
corresponds to the normal scheduled maintenance for most affected 
operators. According to the manufacturer, adequate parts will be 
available to modify the U.S. fleet within the required compliance time. 
However, under the provisions of paragraph (m)(1) of this AD, we will 
consider requests for approval of an extension of the compliance time 
if sufficient data are submitted to substantiate that the new 
compliance time would provide an acceptable level of safety. We have 
not changed this AD in his regard.

Request To Use Later Revisions of the Service Information

    AAL requested that we allow later revisions of Airbus Service 
Bulletin A320-71-1069, dated December 18, 2015, to be used as a method 
of compliance for the actions specified in paragraph (h) of the 
proposed AD.
    We may not refer to any document that does not yet exist in an AD. 
In general terms, we are required by the Office of the Federal 
Register's (OFR) regulations to either publish the service document 
contents as part of the actual AD language; or submit the service 
document to the OFR for approval as ``referenced'' material, in which 
case we may only refer to such material in the text of an AD. The AD 
may refer to the service document only if the OFR approved it for 
``incorporation by reference.'' See 1 CFR part 51.
    To allow operators to use later revisions of the referenced 
document (issued after publication of the AD), either we must revise 
the AD to reference specific later revisions, or operators must request 
approval to use later revisions as an AMOC with this AD under the 
provisions of paragraph (m)(1) of this AD.
    However, since we issued the NPRM, we have received Airbus Service 
Bulletin A320-71-1069, Revision 01, including Appendix 01, dated April 
28, 2016. This revision clarifies a storage location for Groups 7 and 8 
but specifies no additional work requirements from the previous issue 
(Airbus Service Bulletin A320-71-1069, dated December 18, 2015). 
Therefore, we have revised paragraph (h) of this AD to specify Airbus 
Service Bulletin A320-71-1069, Revision 01, including Appendix 01, 
dated April 28, 2016, as an appropriate source of service information 
for accomplishing the required actions. We have also added paragraph 
(l) to this AD to provide credit for actions required by paragraph (h) 
of this AD, if those actions were performed before the effective date 
of this AD using Airbus Service Bulletin A320-71-1069, dated December 
18,

[[Page 29374]]

2015. We have redesignated subsequent paragraphs accordingly.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-71-1069, Revision 01, 
including Appendix 01, dated April 28, 2016. The service information 
describes procedures for modifying the engine FCDs, installing 
placards, and re-identifying the FCDs with new part numbers. This 
service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 558 airplanes of U.S. registry.
    The actions required by AD 2003-18-06, and retained in this AD, 
take about 8 work-hours per product, at an average labor rate of $85 
per work-hour. Required parts cost about $1,500 per product. Based on 
these figures, the estimated cost of the actions that are required by 
AD 2003-18-06 is $2,180 per product.
    We also estimate that it takes about 6 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $9,676 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $5,683,788, or $10,186 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

as applicable, is an acceptable method of compliance with the 
requirements of paragraphs (h)(1) and (h)(3) of this AD for that 
engine FCD only.
    (2) An airplane on which Airbus Modification 157516 has been 
embodied in production is compliant with the requirements of 
paragraphs (h)(1) and (h)(3) of this AD, provided no engine FCD, 
having a part number identified as ``Old Part Number'' in table 1 to 
paragraph (h) of this AD or table 2 to paragraph (h) of this AD, as 
applicable, is installed on that airplane.
    (3) An airplane on which Airbus Modification 157718 has been 
embodied in production is compliant with the requirements of 
paragraph (h)(2) of this AD.

(j) New Parts Installation Limitations

    (1) For an airplane with an engine FCD installed having a part 
number identified as ``Old Part Number'' in table 1 to paragraph (h) 
of this AD or table 2 to paragraph (h) of this AD, as applicable: 
After modification of that airplane as required by paragraph (h) of 
this AD, do not install an engine FCD, having a part number 
identified as ``Old Part Number'' in table 1 to paragraph (h) of 
this AD or table 2 to paragraph (h) of this AD, as applicable.
    (2) For an airplane that does not have an engine FCD installed

(g), (h)(1), and (h)(3) of this AD for that engine only, provided 
the part number is approved, and the installation is accomplished, 
in accordance with the procedures specified in paragraph (m)(2) of 
this AD.

(l) Credit for Previous Actions

    This paragraph provides credit for actions required by paragraph 
(h) of this AD, if those actions were performed before the effective 
date of this AD using Airbus Service Bulletin A320-71-1069, dated 
December 18, 2015.

(m) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. In accordance with 14 CFR 
39.19, send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Branch, send it to the attention of 
the person identified in paragraph (n)(2) of this AD. Information 
may be emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any 
approved AMOC, notify your appropriate principal inspector, or 
lacking a principal inspector, the manager of the local flight 
standards district office/certificate holding district office.
    (2) Contacting the Manufacturer: As of the effective date of 
this AD, for any requirement in this AD to obtain corrective actions 
from a manufacturer, the action must be accomplished using a method 
approved by the Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA; or the European Aviation Safety Agency 
(EASA); or Airbus's EASA Design Organization Approval (DOA). If 
approved by the DOA, the approval must include the DOA-authorized 
signature.
    (3) Required for Compliance (RC): Except as required by 
paragraph (k) of this AD, if any service information contains 
procedures or tests that are identified as RC, those procedures and 
tests must be done to comply with this AD; any procedures or tests 
that are not identified as RC are recommended. Those procedures and 
tests that are not identified as RC may be deviated from using 
accepted methods in accordance with the operator's maintenance or 
inspection program without obtaining approval of an AMOC, provided 
the procedures and tests identified as RC can be done and the 
airplane can be put back in an airworthy condition. Any 
substitutions or changes to procedures or tests identified as RC 
require approval of an AMOC.
