ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Raytheon (Beech) Model 400, 400A, and 400T series airplanes. This proposed AD would require modifying the attachment fasteners on the engine cowling panels. This proposed AD results from several reports of loose attachment fasteners found on the engine cowling panels, and subsequently the panels either peeling back or separating from the airplane during flight. We are proposing this AD to prevent failure of the attachment fasteners on the engine cowling panels, which could result in separation of a panel from the airplane, and consequent damage to airplane structure. These conditions could adversely affect continued safe flight and landing of the airplane, or cause injury to people or damage to property on the ground. DATES: We must receive comments on this proposed AD by July 13, 2007.

Comments will be available in the AD docket shortly after the Docket Management System receives them. Discussion We have received several reports indicating loose attachment fasteners (1⁄4-turn fasteners not fully engaged) were found on the engine cowling panels on certain Raytheon (Beech) Model 400, 400A, and 400T series airplanes. Subsequently, the cowling panels either peeled back or separated from the airplane during flight. In one incident a cowling piece departed the airplane and landed within 50 feet of a residence. Investigation revealed that the loose fasteners are not detected during the pre-flight inspection and that aerodynamic loads may forcibly separate the panel from the airplane during flight. The separation forces could result in the panel causing damage to the engine or nacelle installation, in addition to other parts of the airplane. These conditions could adversely affect continued safe flight and landing of the airplane, or cause injury to people or damage to property on the ground. Relevant Service Information We have reviewed Raytheon Service Bulletin SB 54–3788, dated December, 2006. The service bulletin describes procedures for modifying the attachment fasteners on the engine cowling panels. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other airplanes of this same type design. For this reason, we are proposing this AD, which would require accomplishing the actions specified in E:\FR\FM\29MYP1.SGM 29MYP1 Federal Register / Vol. 72, No. 102 / Tuesday, May 29, 2007 / Proposed Rules for a location to examine the regulatory evaluation. Costs of Compliance There are about 757 airplanes of the affected design in the worldwide fleet. This proposed AD would affect about 575 airplanes of U.S. registry. The proposed actions would take about 10 work hours per airplane, at an average labor rate of $80 per work hour. Required parts would cost about $400 per airplane. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $690,000, or $1,200 per airplane. List of Subjects in 14 CFR Part 39 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. rwilkins on PROD1PC63 with PROPOSALS the service information described previously. 1.

Discussion

    We have received several reports indicating loose attachment 
fasteners (\1/4\-turn fasteners not fully engaged) were found on the 
engine cowling panels on certain Raytheon (Beech) Model 400, 400A, and 
400T series airplanes. Subsequently, the cowling panels either peeled 
back or separated from the airplane during flight. In one incident a 
cowling piece departed the airplane and landed within 50 feet of a 
residence. Investigation revealed that the loose fasteners are not 
detected during the pre-flight inspection and that aerodynamic loads 
may forcibly separate the panel from the airplane during flight. The 
separation forces could result in the panel causing damage to the 
engine or nacelle installation, in addition to other parts of the 
airplane. These conditions could adversely affect continued safe flight 
and landing of the airplane, or cause injury to people or damage to 
property on the ground.

Relevant Service Information

    We have reviewed Raytheon Service Bulletin SB 54-3788, dated 
December, 2006. The service bulletin describes procedures for modifying 
the attachment fasteners on the engine cowling panels. Accomplishing 
the actions specified in the service information is intended to 
adequately address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to exist or develop on other airplanes 
of this same type design. For this reason, we are proposing this AD, 
which would require accomplishing the actions specified in

[[Page 29447]]

the service information described previously.

Costs of Compliance

    There are about 757 airplanes of the affected design in the 
worldwide fleet. This proposed AD would affect about 575 airplanes of 
U.S. registry. The proposed actions would take about 10 work hours per 
airplane, at an average labor rate of $80 per work hour. Required parts 
would cost about $400 per airplane. Based on these figures, the 
estimated cost of the proposed AD for U.S. operators is $690,000, or 
$1,200 per airplane.

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); 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 proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.
