# 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 A330-200, -200 Freighter, and -300 series airplanes; and all Airbus Model A340-200, -300, -500, and -600 series airplanes. This proposed AD was prompted by reports of cracks at certain frames of the forward cargo door. This proposed AD would require a detailed inspection for cracking of certain forward cargo doors, and repair if necessary. We are proposing this AD to detect and correct cracking at certain frames, which could result in the loss of structural integrity of the forward cargo door.

## Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0228, dated October 20, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and all Airbus Model A340-200, -300, -500, and -600 series airplanes. The MCAI states:

An A330 aeroplane operator reported recently cases of crack findings on two different aeroplanes, at frame 20A and at frame 20B close to beam 3 of the forward cargo door. The first finding was detected during scheduled maintenance, while the second one was found during an inspection prompted by the first finding. Subsequent analyses of these cracks identified that the first crack initiated at frame 20B, which is the first primary load path, leading to excessive loads at frame 20A and consequent cracking. Nevertheless, on the other aeroplane, a crack was detected on frame 20A only. Rupture of both frames 20A and 20B could lead to frame 21 failure after a limited number of flight cycles (FC).

This condition, if not detected and corrected, may potentially result in the loss of structural integrity of the forward cargo door, which could ultimately jeopardise the aeroplane's safe flight.

Prompted by these findings, Airbus issued Alert Operators Transmission (AOT) A52L010-14 to provide instructions for a one-time inspection of frames 20A, 20B and 21 in the area of beam 3, until the half pitch between beam 2 and beam 3.

For the reasons described above, this [EASA] AD requires identification of the Part Number (P/N) of the affected forward cargo doors, a one-time detailed inspection (DET) of each affected door and, depending on findings, accomplishment of applicable corrective action(s) [contacting Airbus].

This [EASA] AD is considered to be an interim action and further AD action may follow.

                    Required actions also include sending inspection results to Airbus. 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-2015-0675.                

## Related Service Information Under 1 CFR Part 51

                    Airbus has issued Alert Operators Transmission (AOT) A52L010-14, dated September 30, 2014. The service information describes procedures for an inspection for cracking of certain forward cargo doors, and repair if necessary. The actions described in this AOT are intended to correct the unsafe condition identified in the MCAI. This service information is reasonably available; see                     **ADDRESSES**                     for ways to access this service information.                

## 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 89 airplanes of U.S. registry.

We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost $0 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $7,565, or $85 per product.

In addition, we estimate that any necessary follow-on actions would take about 32 work-hours and require parts costing $654,850, for a cost of $657,570 per product. We have no way of determining the number of aircraft that might need this action.

## 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 proposed AD is 2120-0056. The paperwork cost associated with this proposed 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 proposed 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.

## 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;                          ( print page 17002)    

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.
