ADDRESSES Discussion We received several reports of problems associated with the uncommanded operation of the forward, aft, and nose cargo doors of Boeing Model 747 airplanes that had accumulated between 9,390 and 22,529 total flight cycles; and cargo doors 1 and 2 of Boeing Model 757 airplanes that had accumulated between 4,300 and 30,000 total flight cycles. Tests of the cargo door control switches have shown that the control switches remained in the closed position after they were released, which caused the cargo doors to continue moving. The cause of the switch failure is related to the rated switch operation life cycle. This condition, if not corrected, could result in injuries to persons and damage to the airplane and equipment. Relevant Service Information We have reviewed Boeing Special Attention Service Bulletin 747–52– 2286, dated September 28, 2007 (for Model 747 airplanes). This service bulletin describes procedures for replacing the control switches of the forward, aft, and nose cargo doors with new control switches. We have also reviewed Boeing Special Attention Service Bulletin 757–52– 0090, dated September 21, 2007 (for Model 757 airplanes). This service bulletin describes procedures for replacing the control switches of cargo doors 1 and 2 with new control switches. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. FAA’s Determination and Requirements of This Proposed AD We are proposing this AD because we evaluated all relevant information and determined the unsafe condition E:\FR\FM\23DEP1.SGM 23DEP1 Federal Register / Vol. 73, No. 247 / Tuesday, December 23, 2008 / Proposed Rules described previously is likely to exist or develop in other products of these same type designs. This proposed AD would require accomplishing the actions specified in the service information described previously. Costs of Compliance We estimate that this proposed AD would affect 765 airplanes of U.S. registry. We also estimate that it would take about 2 to 3 work-hours per product to comply with this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $130 to $195 per airplane. Based on these figures, we estimate the cost of this proposed AD to U.S. operators up to $332,775 fleet cost, or between $290 and $435 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 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), 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.

Discussion

    We received several reports of problems associated with the 
uncommanded operation of the forward, aft, and nose cargo doors of 
Boeing Model 747 airplanes that had accumulated between 9,390 and 
22,529 total flight cycles; and cargo doors 1 and 2 of Boeing Model 757 
airplanes that had accumulated between 4,300 and 30,000 total flight 
cycles. Tests of the cargo door control switches have shown that the 
control switches remained in the closed position after they were 
released, which caused the cargo doors to continue moving. The cause of 
the switch failure is related to the rated switch operation life cycle. 
This condition, if not corrected, could result in injuries to persons 
and damage to the airplane and equipment.

Relevant Service Information

    We have reviewed Boeing Special Attention Service Bulletin 747-52-
2286, dated September 28, 2007 (for Model 747 airplanes). This service 
bulletin describes procedures for replacing the control switches of the 
forward, aft, and nose cargo doors with new control switches.
    We have also reviewed Boeing Special Attention Service Bulletin 
757-52-0090, dated September 21, 2007 (for Model 757 airplanes). This 
service bulletin describes procedures for replacing the control 
switches of cargo doors 1 and 2 with new control switches.
    Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition.

FAA's Determination and Requirements of This Proposed AD

    We are proposing this AD because we evaluated all relevant 
information and determined the unsafe condition

[[Page 78673]]

described previously is likely to exist or develop in other products of 
these same type designs. This proposed AD would require accomplishing 
the actions specified in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD would affect 765 airplanes of 
U.S. registry. We also estimate that it would take about 2 to 3 work-
hours per product to comply with this proposed AD. The average labor 
rate is $80 per work-hour. Required parts would cost about $130 to $195 
per airplane. Based on these figures, we estimate the cost of this 
proposed AD to U.S. operators up to $332,775 fleet cost, or between 
$290 and $435 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 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), 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.
