Airworthiness Directives; Hawker Beechcraft Corporation Models 58, 58A, 58P, 58PA, 58TC, 58TCA, 95-B55, 95-B55A, A36, A36TC, B36TC,

E55, E55A, F33A, and V35B Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of

Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

SUMMARY: We propose to supersede Airworthiness Directive (AD) 91-18-19, which applies to certain Hawker Beechcraft Corporation (Hawker) (Type

Certificate Numbers 3A15, 3A16, and A23CE formerly held by Raytheon

Aircraft Company; formerly held by Beech Aircraft Corporation) Models 58, 58A, 58P, 58PA, 58TC, 58TCA, 95-B55, 95-B55A, A36, A36TC, B36TC,

E55, E55A, F33A, and V35B airplanes. AD 91-18-19 currently requires you to do a one-time inspection of the pilot and copilot shoulder harnesses for an incorrect washer and replace any incorrect washer with the correct washer. Since we issued AD 91-18-19, we have found that the applicability of AD 91-18-19 was incorrectly stated when the Model

A36TC airplane was omitted from the Applicability section.

Consequently, this proposed AD would retain the actions and the serial number (SN) applicability of AD 91-18-19 and realign the SN applicability for Models A36TC and B36TC airplanes. We are proposing this AD to detect and correct an incorrect washer installed in the pilot and copilot shoulder harnesses. This failure could result in a malfunctioning shoulder harness. Such a failure could lead to occupant injury.

DATES: We must receive comments on this proposed AD by October 27, 2009.

Discussion

Reports of incorrect washers installed in the pilot and copilot shoulder harnesses on certain Beech 33, 35, 36, 55, 58, and 95 series airplanes caused us to issue AD 91-18-19, Amendment 39-8022 (56 FR 42224, August 24, 1991). AD 91-18-19 currently requires the following on Models 58, 58A, 58P, 58PA, 58TC, 58TCA, 95-B55, 95-B55A, A36, B36TC,

E55, E55A, F33A, and V35B airplanes:

Inspecting the pilot and copilot shoulder harnesses for incorrect washers; and

Replacing any incorrect washers found with a part number

(P/N) 100951X060YA washer.

The FAA has identified that the applicability of AD 91-18-19 was incorrectly stated when the Model A36TC airplane was omitted from the

Applicability section. Further, SNs of the Model A36TC airplane were incorrectly aligned to the Model B36TC airplane.

This condition, if not corrected, could result in an incorrect washer installed in the pilot and copilot shoulder harnesses. This failure could result in a malfunctioning shoulder harness. Such a failure could lead to occupant injury.

Relevant Service Information

We have reviewed Beechcraft Mandatory Service Bulletin No. 2394, dated December 1990.

The service information describes procedures for:

Inspecting the pilot and copilot shoulder harnesses for incorrect washers; and

Replacing any incorrect washers found with a P/N 100951X060YA washer.

FAA's Determination and Requirements of the Proposed AD

We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would supersede AD 91-18-19 with a new AD that would incorporate the actions in the previously-referenced service information. This proposed

AD would require you to use the service information described previously to perform these actions.

Costs of Compliance

We estimate that this proposed AD would affect 4,792 airplanes in the U.S. registry.

We estimate the following costs to do the proposed inspection:

Total cost Total cost

Labor cost

Parts cost

per

on U.S. airplane operators

1 work-hour x $80 per hour = Not applicable.

$80

$383,360

$80.

We estimate the following costs to do any necessary replacements that would be required based on the results of the proposed inspection.

We have no way of determining the number of airplanes that may need this replacement:

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.

Examining the AD Docket

You may examine the AD docket that contains the proposed AD, the regulatory evaluation, any comments received, and other information on the Internet at http://www.regulations.gov; or in person at the Docket

Management Facility between 9 a.m. and 5 p.m.,

Page 44313

Monday through Friday, except Federal holidays. The Docket Office

(telephone (800) 647-5527) is located at the street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
