Federal Aviation Administration (FAA), DOT.
Notice of proposed rulemaking (NPRM).
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.
We must receive comments on this proposed AD by April 4, 2016.
You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

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 Start Printed Page 8156information 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.
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.
