Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede an existing airworthiness directive (AD)
Page 46344
that applies to certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes; and certain Model 757-200, -200PF, and -300 series airplanes. The existing AD currently requires replacing the control switches of the forward, aft, and nose cargo doors for certain airplanes, and replacing the control switches of cargo doors 1 and 2 for certain airplanes. Since we issued that AD, we have determined that additional airplanes are affected by the identified unsafe condition. This proposed AD would continue to require replacing the control switches of the forward, aft, and nose cargo doors of Model 747 airplanes; and the control switches of cargo doors 1 and 2 of Model 757 airplanes; this proposed AD also adds airplanes to the applicability and revises the initial compliance times. We are proposing this AD to prevent injuries to persons and damage to the airplane and equipment.
DATES: We must receive comments on this proposed AD by September 17, 2012.

Discussion
On October 19, 2009, we issued AD 2009-22-08, Amendment 39-16059 (74 FR 55763, October 29, 2009), for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes; and certain Model 757-200, -200PF, and -300 series airplanes. That AD requires replacing the control switches of the forward, aft, and nose cargo doors for certain airplanes, and replacing the control switches of cargo doors 1 and 2 for certain airplanes. That AD resulted from reports of problems associated with the uncommanded operation of cargo doors. We issued that AD to prevent injuries to persons and damage to the airplane and equipment.
Actions Since Existing AD Was Issued
Since we issued AD 2009-22-08, Amendment 39-16059 (74 FR 55763, October 29, 2009), we have determined that additional airplanes are affected by the identified unsafe condition.
Relevant Service Information
We reviewed Boeing Special Attention Service Bulletin 747-52-2286, Revision 1, dated October 28, 2010. This service bulletin describes procedures for replacing the control switches of the forward, aft, and nose cargo doors with new switches. This service bulletin also adds Group 3 airplanes, and also changes the compliance time for Groups 1 and 2 airplanes.
FAA's Determination
We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs.
Proposed AD Requirements
This proposed AD would retain all requirements of AD 2009-22-08, Amendment 39-16059 (74 FR 55763, October 29, 2009). This proposed AD would add Group 3 airplanes, as specified in Boeing Special Attention Service Bulletin 747-52-2286, Revision 1, dated October 28, 2010, and would change the compliance time for Groups 1 and 2 airplanes. This proposed AD would also require accomplishing the actions specified in the service information described previously.
Change to Existing AD
This proposed AD would retain all requirements of AD 2009-22-08, Amendment 39-16059 (74 FR 55763, October 29, 2009). Since AD 2009-22-08 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this proposed AD, as listed in the following table:
Revised Paragraph Identifiers

Costs of Compliance
We estimate that this proposed AD affects 225 airplanes of U.S. registry.
We estimate the following costs to comply with this proposed AD:

airplanes.
--------------------------------------------------------------------------------------------------------------------------------------------------------
According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate.
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 have 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 that the 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.
