**SUPPLEMENTARY INFORMATION :**  On September 9, 2009, we issued AD 2009– 19–06, which applies to certain Boeing Model 747–100, 747–100B, 747–100B SUD, 747–200B, 747–200F, 747–300, 747–400, 747–400D, 747SP, and 747SR series airplanes.
Background

We have received a report indicating that the current design of the flight deck door is defective. This condition, if not corrected, could jeopardize flight safety.

Relevant Service Information

We reviewed Boeing Service Bulletin 747–52–2293, dated September 4, 2009. The service bulletin describes procedures for installing certain equipment associated with the flight deck door. FAA’s Determination and Requirements of This AD

Since the unsafe condition described is likely to exist or develop on other airplanes of the same type design, we issued AD 2009–19–06 to prevent failure of the flight deck door, which could jeopardize flight safety. The AD requires accomplishing the actions specified in the service information previously described.

We have determined that notice and opportunity for prior public comment on AD 2009–19–06 were contrary to the public interest, and good cause existed to make the AD effective immediately by individual notices issued on September 9, 2009, to the known U.S. owners and operators of certain Boeing Model 747–100, 747–100B, 747–100B SUD, 747–200B, 747–200F, 747–300, 747–400, 747–400D, 747SP, and 747SR series airplanes. These conditions still exist, and the AD is hereby published in the Federal Register as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13) to make it effective to all persons.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the **ADDRESSES** section. Include ‘‘ Docket No. FAA– 2010–0950; Directorate Identifier 2009– NM–194–AD ’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this 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

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 that this AD:

(1) Is not a ‘‘ significant regulatory action ’’ under Executive Order 12866,

(2) Is not a ‘‘ significant rule ’’ under 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.

You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket. List of Subjects in 14 CFR Part 39

**RIN 2120–AA64**

**Airworthiness Directives; Bombardier, Inc. Model DHC–8 Airplanes** 

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

**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new 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:

The landing gear alternate extension system in the cockpit is accessible through an access panel located on the cockpit floor. There have been reports of failure of the access panel latch assembly as a consequence of repeated closure of the access panel involving the use of excessive force. Failure of the latch assembly can result in the access panel being jammed in the closed position, and require mechanical prying to open.

An undetected or uncorrected latch failure condition in the access panel can prevent immediate access to the landing gear alternate extension system by the flight crew during an emergency. * * * We are issuing this AD to require actions to correct the unsafe condition on these products.

**DATES :**  This AD becomes effective November 12, 2010.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of November 12, 2010.

**ADDRESSES :**  You may examine the AD docket on the Internet at http:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC. **FOR FURTHER INFORMATION CONTACT :**  Craig Yates, Aerospace Engineer, Airframe and Mechanical Systems Branch, ANE–171, New York Aircraft Certification Office, FAA, 1600 Stewart Avenue, Suite 410, Westbury, New York 11590; telephone (516) 228–7355; fax (516) 794–5531.

**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 July 1, 2010 (75 FR 38064). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

The landing gear alternate extension system in the cockpit is accessible through an access panel located on the cockpit floor. There have been reports of failure of the access panel latch assembly as a consequence of repeated closure of the access panel involving the use of excessive force. Failure of the latch assembly can result in the access panel being jammed in the closed position, and require mechanical prying to open.

An undetected or uncorrected latch failure condition in the access panel can prevent immediate access to the landing gear alternate extension system by the flight crew during an emergency. This Directive requires the replacement of the existing latch assembly with a stronger modified latch assembly. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Bombardier, Inc. issued Service Bulletin 8–32–166, Revision B, dated March 2, 2010. We cited Bombardier Service Bulletin 8–32–166, Revision A, dated January 29, 2009, in the NPRM. Bombardier Service Bulletin 8–32–166, Revision B, dated March 2, 2010, updates the References section and adds a Note to the Accomplishment Instructions section. We have changed paragraph (g) of this AD to specify Revision B of that service bulletin, and added Bombardier Service Bulletin 8– 32–166, Revision A, dated January 29, 2009, to paragraph (h) of this AD.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the comments received. Air Line Pilots Association, International, supports the NPRM. Hawaii Island Air, Piedmont Airlines, and Mesa Airlines request that we revise the NPRM to refer to Bombardier Service Bulletin 8–32– 166, Revision B, dated March 2, 2010, as described previously.
