We are revising an earlier notice of proposed rulemaking (NPRM) to supersede Airworthiness Directive (AD) 2004-23-20. AD 2004- 23-20 applies to certain Airbus Model A300 B2-1A, A300 B2-1C, A300 B2K- 3C, A300 B2-203, A300 B4-2C, A300 B4-103, and A300 B4-203 airplanes; and Model A300 B4-601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4- 605R, A300 B4-622R, A300 F4-605R and A300 C4-605R Variant F airplanes. This action revises the NPRM by reducing certain compliance times, among other changes. We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions impose an additional burden over those proposed in the NPRM we are reopening the comment period to allow the public the chance to comment on these proposed changes.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening 
of comment period.

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

SUMMARY: We are revising an earlier notice of proposed rulemaking 
(NPRM) to supersede Airworthiness Directive (AD) 2004-23-20. AD 2004-
23-20 applies to certain Airbus Model A300 B2-1A, A300 B2-1C, A300 B2K-
3C, A300 B2-203, A300 B4-2C, A300 B4-103, and A300 B4-203 airplanes; 
and Model A300 B4-601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-
605R, A300 B4-622R, A300 F4-605R and A300 C4-605R Variant F airplanes. 
This action revises the NPRM by reducing certain compliance times, 
among other changes. We are proposing this airworthiness directive (AD) 
to address the unsafe condition on these products. Since these actions 
impose an additional burden over those proposed in the NPRM we are 
reopening the comment period to allow the public the chance to comment 
on these proposed changes.

DATES: The comment period for the NPRM published in the Federal 
Register on February 1, 2016 (81 FR 5056), is reopened.

Discussion

    On November 10, 2004, we issued AD 2004-23-20, Amendment 39-13875 
(69 FR 68779, November 26, 2004) (``AD 2004-23-20''). AD 2004-23-20 
requires actions intended to address an unsafe condition on certain 
Airbus Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-
203 airplanes; and Model A300 B4-601, A300 B4-603, A300 B4-620, A300 
B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R and A300 C4-605R 
Variant F airplanes.
    We issued an NPRM to amend 14 CFR part 39 by adding an AD to 
supersede AD 2004-23-20 that would apply to certain Airbus Model A300 
B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes; and 
Model A300 B4-601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, 
A300 B4-622R, A300 F4-605R and A300 C4-605R Variant F airplanes. The 
NPRM published in the Federal Register on February 1, 2016 (81 FR 5056) 
(``the NPRM''). The NPRM was prompted by a report indicating that the 
material used to manufacture the upper frame feet was changed and 
negatively affected the fatigue life of the frame feet. The NPRM 
proposed to reduce the compliance times for the initial inspection and 
the inspection intervals. The NPRM also proposed to expand the 
applicability and require an additional repair on certain airplanes 
that have been modified.

Actions Since the NPRM Was Issued

    Since we issued the NPRM, we have determined the compliance times 
for the proposed modification must be reduced and an additional 
modification must be done. In addition, we have determined that the 
repetitive inspections are no longer necessary. Therefore, certain 
requirements identified as ``retained'' in the proposed AD (in the 
NPRM) have been removed from this proposed AD.

[[Page 27445]]

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0249, dated December 14, 2016; corrected January 10, 2017 
(referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''); to correct an unsafe condition for all 
Airbus Model A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, A300 
B4-622R, A300 F4-605R, A300 F4-622R, and A300 C4-605R Variant F 
airplanes. The MCAI states:

    During an inspection in accordance with Airworthiness Limitation 
Item (ALI) 53-15-54 on an A300-600 aeroplane, Frames (FR) 43, FR44, 
FR45 and FR46 were found cracked between stringer (STGR) 24 and 
STGR30 on the aeroplane right hand side. FR45 was also found cracked 
on the aeroplane left hand side.
    This condition, if not detected and corrected, could reduce the 
structural integrity of the fuselage.
    To address this potential unsafe condition and improve the 
fatigue life of the upper frame feet fittings, Airbus issued Service 
Bulletin (SB) A300-53-6125 to provide instructions for expansion of 
the most sensitive fastener holes between FR41 and FR46. DGAC 
[Direction G[eacute]n[eacute]rale de l'Aviation Civile] France 
issued AD F-2004-002 (EASA approval 2003-2108) [which corresponds to 
FAA AD 2004-23-20] to require the structural modification defined in 
SB A300-53-6125 Revision 03 (Airbus modification 12168).
    [DGAC] AD F-2004-002 was subsequently superseded by EASA AD 
2013-0295 to amend the inspection programme in this area as provided 
in SB A300-53-6122 (which is now obsolete and replaced by ALI task 
531558, published in the [Airworthiness Limitation Section] ALS Part 
2 Revision 01 dated 07 August 2015).
    Since EASA AD 2013-0295 was issued, a new investigation was 
conducted in the frame of the Widespread Fatigue Damage study. 
Airbus revised the thresholds for the accomplishment of the 
instructions defined in SB A300-53-6125 and issued SB A300-53-6178 
to provide modification instructions to improve the fatigue life of 
upper frame feet fittings on aeroplane on which Airbus modification 
(mod) 12168 or Airbus SB A300-53-6125 was embodied.
    For the reason described above, this [EASA] AD retains some 
requirements of EASA AD 2013-0295, which is superseded, and requires 
modification of the upper frame feet fittings from FR41 to FR46 
[repetitive inspections are not retained].
    This [EASA] AD is republished to correct a typographical error 
in the compliance time * * *.

    We have also removed Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-
2C, B4-103, and B4-203 airplanes from the applicability of this 
proposed AD. We have issued AD 2017-05-01, Amendment 39-18811 (82 FR 
12401, March 3, 2017), which addresses the identified unsafe condition 
on all Model A300 series airplanes.
    In addition, we have removed Model A300 B4-601 airplanes from the 
applicability of this proposed AD. The airplane manufacturer stated 
that all serial numbers for this airplane model have been removed from 
service. Also, we have added Model A300 F4-622R airplanes to the 
applicability of this proposed AD to correspond with the applicability 
in the MCAI.
    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-
0451.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A300-53-6125, Revision 04, dated 
March 17, 2015; and Service Bulletin A300-53-6178, dated March 17, 
2015. The service information describes procedures for the modification 
of certain upper frame feet fittings. These documents are distinct 
since they apply to airplanes in different configurations.
    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.

Comments

    We gave the public the opportunity to participate in developing 
this proposed AD. We considered the comments received.

Request To Specify That Reporting Is Optional

    FedEx requested that the reporting action specified in Airbus 
Service Bulletin A300-53-6122 be identified as an optional action in 
the NPRM. The commenter stated that the NPRM does not include a 
statement that the reporting requirements specified in Airbus Service 
Bulletin A300-53-6122 are not required by the NPRM. The commenter 
stated that Airbus has received these reports in the past and has not 
provided statistics or benefits to operators.
    We agree with the commenter that reporting should not be required. 
All references to Airbus Service Bulletin A300-53-6122 have been 
omitted from this proposed AD. Since the NPRM was issued, Airbus has 
included the inspections specified in Airbus Service Bulletin A300-53-
6122 in appropriate airworthiness limitations. Since this proposed AD 
does not include any references to Airbus Service Bulletin A300-53-
6122, we have not revised this proposed AD in regard to this issue.

Request To Extend the Grace Period in Paragraph (n)(1) of the Proposed 
AD

    FedEx requested that the grace period in paragraph (n)(1) of the 
proposed AD (in the NPRM) be extended from 1,000 flight cycles to 2,000 
flight cycles. The commenter noted that this would permit scheduling 
this inspection and modification at the next major maintenance check 
and would not impose any additional scheduling burden on operators. The 
commenter stated that this would only affect seven airplanes in its 
fleet that are currently awaiting the initial threshold for the 
inspection. The commenter also mentioned that its experience to date 
has not shown wide spread fatigue cracking in this area under the 
existing 15,000-flight-cycle threshold.
    As stated previously, certain inspections, including those 
specified in paragraph (m)(1) of the proposed AD (in the NPRM), are not 
included in this proposed AD. Therefore, it is not necessary to extend 
the grace period for the initial rotating probe inspection (which 
corresponds to paragraph (n)(1) of the proposed AD (in the NPRM)). We 
have not changed this proposed AD regarding this issue.

Request To Revise the Compliance Times in Paragraph (o) of the Proposed 
AD

    United Parcel Service (UPS) requested that the NPRM be revised to 
simplify the compliance requirements in paragraph (o) of the proposed 
AD to reflect the current service experience of the fleet. UPS noted 
that almost 12 years have passed between the issuance of AD 2004-23-20 
and the NPRM. UPS pointed out that during this time new information 
regarding structural fatigue has been developed and this information is 
not reflected in the NPRM. In addition, UPS stated that, while it is 
the FAA's standard practice to supersede an AD but retain information 
from the AD being superseded in an NPRM, in this NPRM, the compliance 
times in paragraph (o) of the proposed AD are confusing and difficult 
to interpret.
    We agree with the commenter's request to clarify and simplify the 
compliance times in paragraph (g)(1) of this proposed AD (which 
corresponds to paragraphs (o)(1)(i) and (o)(1)(ii) of the proposed AD 
(in the NPRM)), for the reasons provided by the commenter. We have 
revised the compliance times in paragraph (g)(1) of this proposed AD to 
correspond with the compliance times specified in the MCAI.

[[Page 27446]]

Request To Include Inspection in One Location

    UPS requested that we either include the inspection specified in 
paragraph (n)(1)(i) of the proposed AD (in the NPRM) as an AD 
requirement or as an airworthiness limitation. UPS stated that the 
inspection specified in Airbus Service Bulletin A300-53-6125, which is 
mandated by paragraph (n)(1)(i) of the proposed AD (in the NPRM), is a 
duplicate of ALI task 53-15-58. UPS noted that the NPRM and 
airworthiness limitation documents have different inspection interval 
requirements and there is the potential for duplicate and conflicting 
requirements if either document is revised.
    We agree with the commenter's observation regarding duplicate 
inspection requirements. ALI task 53-15-58 was revised in Airbus ALS 
Part 2, Variation 13.2, to include the inspection in ALI task 53-15-58-
03. The inspection is required for airplanes that have not incorporated 
the actions specified in Airbus Service Bulletin A300-53-6125 and is no 
longer required for airplanes that have incorporated the actions 
specified in Airbus Service Bulletin A300-53-6125. The FAA issued 
Alternative Method of Compliance (AMOC) ANM-116-15-387 to AD 2013-13-
13, Amendment 39-17501 (79 FR 48957, August 19, 2014), that allows 
operators to revise their maintenance or inspection programs by 
incorporating Airbus ALS Part 2, Variation 13.2. We are working on 
proposed rulemaking that would require operators to incorporate the 
latest version of Airbus ALS Part 2, which includes the inspection 
mentioned previously by the commenter. The inspections in paragraph 
(m)(1) of the proposed AD (in the NPRM), along with the associated 
compliance times in paragraph (n)(1) of the proposed AD (in the NPRM), 
are not included in the requirements of this proposed AD. Therefore, no 
changes to this proposed AD are necessary regarding this issue.

FAA's Determination and Requirements of This SNPRM

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.
    Certain changes described above expand the scope of the rulemaking. 
As a result, we have determined that it is necessary to reopen the 
comment period to provide additional opportunity for the public to 
comment on this SNPRM.

Differences Between This SNPRM and the MCAI

    There is a difference between this SNPRM and the MCAI regarding how 
the compliance time is stated for the post-modification actions 
specified in paragraph (h) of this proposed AD. The MCAI states that 
the post-modification actions should be accomplished ``no later than 6 
months (estimated by projection of airplane usage) prior to exceeding 
24,500 flight cycles or 42,700 flight hours, whichever occurs first 
after Airbus SB A300-53-6178 embodiment.'' Paragraph (h) of this 
proposed AD specifies that the post-modification actions should be done 
``Prior to exceeding 24,100 total flight cycles or 42,000 total flight 
hours, whichever occurs first after doing the modification required by 
paragraph (g)(2) of this AD.'' The compliance time in paragraph (h) of 
this proposed AD is based upon the average annual utilization of the 
Airbus airplanes identified in paragraph (c) of this proposed AD, which 
is 790 flight cycles and 1,463 flight hours (or 395 flight cycles and 
732 flight hours over 6 months). We have rounded the compliance time in 
paragraph (h) of this proposed AD accordingly.

Costs of Compliance

    We estimate that this SNPRM affects 65 airplanes of U.S. registry.
    The actions that are required by AD 2004-23-20 and retained in this 
SNPRM take about 90 work-hours per product, at an average labor rate of 
$85 per work-hour. Required parts cost about $4,000 per product. Based 
on these figures, the estimated cost of the actions that were required 
by AD 2004-23-20 is $11,650 per product.
    We also estimate that it would take up to 109 work-hours per 
product to comply with the new basic requirements of this SNPRM. The 
average labor rate is $85 per work-hour. Required parts would cost up 
to $6,070 per product. Based on these figures, we estimate the cost of 
this SNPRM on U.S. operators to be $996,775, or $15,335 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.

List of Subjects in 14 CFR Part 39

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

[[Page 27447]]

Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 2004), and 
adding the following new AD:

Airbus: Docket No. FAA-2016-0451; Directorate Identifier 2013-NM-
253-AD.

(a) Comments Due Date

    We must receive comments by July 31, 2017.

(b) Affected ADs

    This AD replaces AD 2004-23-20, Amendment 39-13875 (69 FR 68779, 
November 26, 2004) (``AD 2004-23-20'').

(c) Applicability

    This AD applies to Airbus Model A300 B4-603, A300 B4-620, A300 
B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, A300 F4-622R, and 
A300 C4-605R Variant F airplanes; certificated in any category; all 
manufacturer serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Reason

    This AD was prompted by a report indicating that the material 
used to manufacture the upper frame feet was changed and negatively 
affected the fatigue life of the frame feet. We are issuing this AD 
to prevent cracking of the center section of the fuselage, which 
could result in a ruptured frame foot and reduced structural 
integrity of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Modification of the Upper Frame Feet Fittings

    (1) Except for airplanes identified in table 2 to paragraphs 
(g)(1) and (g)(2) of this AD: At the times specified in table 1 to 
paragraph (g)(1) of this AD, depending on the average flight time 
(AFT), as defined in paragraph (i) of this AD, modify the upper 
frame feet fittings, including doing all applicable related 
investigative and corrective actions, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A300-53-6125, 
Revision 04, dated March 17, 2015 (``SB A300-53-6125, Revision 
04''). Do all applicable related investigative and corrective 
actions before further flight. Where Airbus SB A300-53-6125, 
Revision 04, specifies to contact Airbus for appropriate action, and 
specifies that action as ``RC'' (Required for Compliance): Before 
further flight, accomplish corrective actions in accordance with the 
procedures specified in paragraph (l)(2) of this AD.

  Table 1 to Paragraph (g)(1) of This AD--Modification SB A300-53-6125,
                               Revision 04

(l) 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 (m)(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 EASA; or Airbus's EASA DOA. If 
approved by the DOA, the approval must include the DOA-authorized 
signature.
    (3) Required for Compliance (RC): Except as required by 
paragraphs (g)(1) and (g)(2) 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.
