Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

It has been found the occurrence of two events of aircraft being dispatched with the cargo door opened without indication. In one of the events the aircraft took off with the cargo door opened.

* * * * *

The unsafe condition is a cargo door opening during flight, which could result in reduced structural integrity and consequent rapid decompression of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.

DATES:

This AD becomes effective December 17, 2009.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of December 17, 2009.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on August 18, 2009 (74 FR 41642), and proposed to supersede AD 2007-06-53, Amendment 39-15035 (72 FR 21088, April 30, 2007). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

It has been found the occurrence of two events of aircraft being dispatched with the cargo door opened without indication. In one of the events the aircraft took off with the cargo door opened.

The unsafe condition is a cargo door opening during flight, which could result in reduced structural integrity and consequent rapid decompression of the airplane. Required actions include repetitive inspections of the forward and aft cargo doors to detect signs of interference between the lock handle and the aft edge liner assembly and Start Printed Page 58192reworking the assembly; a one-time inspection for signs of damage of the lateral roller fitting on the forward and aft cargo door frames at the fuselage and replacement of the roller if necessary, and modification of the cargo door, which ends the repetitive inspections. After accomplishing the modification, the actions include incorporating information into the maintenance program to include the operational (OPC) and functional (FNC) checks of the forward and aft cargo doors and accomplishing repetitive OPC and FNC checks. You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

We might also have required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a Note within the AD.

Costs of Compliance

We estimate that this AD will affect about 145 products of U.S. registry.

The actions that are required by AD 2007-06-53 and retained in this AD take about 1 work-hour per product, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the currently required actions is $80 per product.

We estimate that it would take about 7 work-hours per product to comply with the new basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $17,162 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the AD on U.S. operators to be $2,569,690, or $17,722 per product.

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 AD will not have federalism implications under Executive Order 13132. This AD will 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 AD:

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); and

3. 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.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

For the purposes of this AD, a functional check (FNC) is: “A quantitative check to determine if one or more functions of an item perform within specified limits.”

Note 5:

For the purposes of this AD, an operational check (OPC) is: “A task to determine if an item is fulfilling its intended purpose. Since it is a failure finding task, it does not require quantitative tolerances.”

FAA AD Differences

Note 6:

This AD differs from the MCAI and/or service information as follows: Where the MCAI includes a compliance time of “after accomplishment of the modification” for revising the maintenance program for Model ERJ-170 airplanes, we have determined that a compliance time of “within 12 months after the effective date of the AD or within 12 months after accomplishment of the modification, whichever occurs later” is appropriate. This compliance time is equivalent to the compliance time required for Model ERJ-190 airplanes. The manufacturer and ANAC agree with this compliance time.

Other FAA AD Provisions

(l) The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Kenny Kaulia, Aerospace Engineer, International Branch, ANM-116, FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 227-2848; fax (425) 227-1149. Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD. AMOCs approved previously in accordance with AD 2007-06-53, are approved as AMOCs for the corresponding provisions of paragraph (i) of this AD.

(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.

(3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
