Federal Register Volume 81, Issue 32 (February 18, 2016)

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4-603, B4-605R, and B4-622R airplanes; and Model A310-304, -324, and -325 airplanes. This proposed AD was prompted by a report of a crack found on door frame (FR) 73A between stringers 24 and 25. This proposed AD would require inspections around the rivet heads of the seal retainer run-out holes at certain frames and corrective actions if necessary. We are proposing this AD to detect and correct cracking of the door frame, which could result in reduced structural integrity of the airplane.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A300 B4-603, B4-605R, and B4-622R airplanes; and

by a report of a crack found on door frame (FR) 73A between stringers 
24 and 25. This proposed AD would require inspections around the rivet 
heads of the seal retainer run-out holes at certain frames and 
corrective actions if necessary. We are proposing this AD to detect and 
correct cracking of the door frame, which could result in reduced 
structural integrity of the airplane.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2014-0202R1, dated September 19, 2014 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Airbus Model A300 B4-603, B4-
605R, and B4-622R airplanes; and Model A310-304, -324, and -325 
airplanes The MCAI states:

    During the preparation phase for conversion of an A300-600 
aeroplane from passenger to freighter configuration, a crack was 
detected on door frame (FR) 73A, between stringer (STRG) 24 and STRG 
25.
    DGAC France had issued AD 1999-013-276R1 [http://ad.easa.europa.eu/ad/F-1999-013-276R1] to require inspections at FR 
73A in accordance with the instructions of Airbus Service Bulletin 
(SB) A310-53-2107 or SB A300-53-6116, as applicable. However, the 
new crack was found in an area not covered by the existing 
inspection and is therefore addressed by this new [EASA] AD. (DGAC 
France AD 1999-013-276R1 remains in place).
    Further investigations identified that, on A300-600 aeroplanes, 
the areas at FR 56A and FR 57A have the same design and material as 
at FR 73A.
    This condition, if not detected and corrected, could affect the 
structural integrity of the airframe.
    For the reasons described above, this [EASA] AD requires 
repetitive [high frequency eddy current (HFEC)] inspections of the 
rivet heads of the seal retainer run out holes to detect cracks and, 
depending on findings, accomplishment of corrective actions 
[repair].
    Even though no crack has been identified at FR 56A and FR 57A, 
as a preventive measure, the inspection is extended to these areas. 
On A310 aeroplanes, only the area at FR 73A needs to be inspected.
    This [EASA] AD is revised to reduce the applicability to 
aeroplanes in post-MOD 06924 configuration.

    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-
0466.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletins A300-53-6175, and A310-53-2138, 
both dated May 28, 2014. The service

[[Page 8156]]

information describes procedures to do HFEC inspections around the 
rivet heads of the seal retainer run-out holes at certain frame 
locations on the left-hand and right-hand sides. 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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 24 airplanes of U.S. 
registry.
    We also estimate that it would take about 11 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 $22,440, or $935 
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.
