We propose to supersede Airworthiness Directive (AD) 98-18-24, which applies to certain Airbus Model A320 series airplanes. AD 98-18- 24 requires repetitive inspections to detect cracking in the inner flange of a certain door frame, and corrective actions, if necessary. AD 98-18-24 also provides an optional terminating action for the repetitive inspections. Since we issued AD 98-18-24, it has been determined that the compliance times for the repetitive inspections must be reduced. This proposed AD would continue to require the repetitive inspections of the inner flange of a certain door frame, with reduced repetitive inspection intervals, and corrective action if necessary. We are proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 98-18-24, 
which applies to certain Airbus Model A320 series airplanes. AD 98-18-
24 requires repetitive inspections to detect cracking in the inner 
flange of a certain door frame, and corrective actions, if necessary. 
AD 98-18-24 also provides an optional terminating action for the 
repetitive inspections. Since we issued AD 98-18-24, it has been 
determined that the compliance times for the repetitive inspections 
must be reduced. This proposed AD would continue to require the 
repetitive inspections of the inner flange of a certain door frame, 
with reduced repetitive inspection intervals, and corrective action if 
necessary. We are proposing this AD to address the unsafe condition on 
these products.

Discussion

    We issued AD 98-18-24, Amendment 39-10740 (63 FR 49272, September 
15, 1998) (``AD 98-18-24''), for certain A320 series airplanes. AD 98-
18-24 was prompted by the results of a fatigue test on simulated 
flights which revealed cracks on the inner flange of door frame 66 at 
stringers 18 and 20. The cracks were located in the gusset plate 
attachment holes and were hidden by the gusset plates. AD 98-18-24 
requires repetitive inspections to detect cracking in the inner flange 
of door frame 66, and corrective actions if necessary. AD 98-18-24 also 
provides an optional terminating action for the repetitive inspections. 
We issued AD 98-18-24 to detect and correct fatigue cracking in the 
inner flange of door frame 66, which could result in reduced structural 
integrity of the airplane.
    Since we issued AD 98-18-24, based on the results from a full scale 
fatigue test, it has been determined that the repetitive inspection 
intervals must be reduced.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2017-0128, dated July 24, 2017 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A320-211 and A320-231 airplanes. The MCAI states:

    During fatigue test on simulated flights, cracks developed on 
the inner flange of door frame 66 at stringer 18 and 20 positions. 
These cracks were located in the gusset plate attachment holes and 
were hidden by the plates.
    This condition, if not detected and corrected, could affect the 
structural integrity of the fuselage.
    To address this potential unsafe condition, Airbus issued 
Service Bulletin (SB) A320-53-1071, later revised, to provide 
instructions to inspect and repair the gusset plate attachment holes 
at frame 66, at stringers 18, 20 and 22 both left hand (LH) and 
right hand (RH) side of the fuselage (hereafter collectively 
referred to as ``the attachment holes'' in this [EASA] AD), and 
[Airbus] SB A320-53-1072, providing instructions for reworking of 
the attachment holes.
    Consequently, DGAC France issued [French] AD 1996-234-087, later 
revised [which corresponds to FAA AD 98-18-24], requiring repetitive 
inspections and, depending on findings, repair of the attachment 
holes, and including reference to a reworking procedure, which 
constitutes optional terminating action for the repetitive 
inspections of the attachment holes.
    Since that [French] AD was issued, based on results from a full 
scale fatigue test, it was determined that the inspection intervals 
must be reduced. Airbus issued SB A320-53-1071 Revision 03, 
modifying the inspection threshold and intervals, and not changing 
the inspection instructions.
    For the reason described above, this [EASA] AD retains the 
requirement of DGAC France AD 1996-234-087 R1, which is superseded, 
and requires reduction of the repetitive inspection interval.

    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-2018-
0455.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-53-1071, Revision 03, dated 
July 20, 2017. This service information describes procedures for 
detailed inspections of the gusset plate attachment holes at door frame 
66 for cracking and corrective action.
    Airbus also issued Service Bulletin A320-53-1072, Revision 02, 
dated May 5, 2016. This service information describes procedures for 
modification of the gusset frame attachment at door frame 66.
    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.

FAA's Determination and Requirements of This Proposed AD

    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 the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 3 airplanes of U.S. 
registry.

[[Page 24692]]

    The actions required by AD 98-18-24, and retained in this proposed 
AD take about 8 work-hours per product, at an average labor rate of $85 
per work-hour. Based on these figures, the estimated cost of the 
actions that are required by AD 98-18-24 is $680 per product.
    We estimate that it would take about 19 work-hours per product to 
comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $4,845, or $1,615 
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.
    In addition, we estimate that the optional terminating action would 
take about 20 work-hours per product, at an average labor rate of $85 
per work-hour. Required parts costs would be about $60. Based on these 
figures, the estimated cost of the optional terminating action would be 
$1,760 per product.
    We also estimate that it would take about 1 work-hour per product 
to comply with the proposed reporting requirement in this proposed AD. 
The average labor rate is $85 per hour. Based on these figures, we 
estimate the cost of reporting the inspection results on U.S. operators 
to be $255, or $85 per product.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
