Proposed Rule

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

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.

Discussion Back to Top

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 Back to Top

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 Back to Top

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 Back to Top

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:

Labor cost Parts cost Total cost per airplane Total cost on U.S. operators
1 work-hour × $80 per hour = $80 Not applicable $80 $383,360

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:

Labor cost Parts cost Total cost per airplane
1 work-hour × $80 per hour = $80 $5 $85

Authority for This Rulemaking Back to Top

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 Back to Top

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 Back to Top

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., 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.

We are issuing 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.

Compliance Back to Top

(e) To address this problem, you must do the following, unless already done:

Actions Compliance Procedures
(1) Inspect the washers on the “D” ring of the pilot and copilot shoulder harnesses for correct metal, inner and outer diameter, and thickness (i) For Group 1 Airplanes: Within the next 100 hours time-in-service (TIS) after October 21, 1991 (the effective date of AD 91-18-19) (ii) For Group 2 Airplanes: Within the next 100 hours TIS after the effective date of this AD Follow Beechcraft Mandatory Service Bulletin No. 2394, dated December 1990.
(2) If you find, as a result of the inspection required by paragraph (e)(1) of this AD, any washer does not meet the criteria for correct metal, inner and outer diameter, and thickness, replace the incorrect washer with part number 100951X060YA washer Before further flight, after the inspection required by paragraph (e)(1) of this AD Follow Beechcraft Mandatory Service Bulletin No. 2394, dated December 1990.

Alternative Methods of Compliance (AMOCs) Back to Top

(f) The Manager, Wichita Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Steve Potter, Aerospace Engineer, ACE-118W, Wichita Aircraft Certification Office (ACO), 1801 Airport Road, Room 100, Wichita, Kansas 67209; telephone: (316) 946-4124; fax: (316) 946-4107. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.

(g) In reviewing the docket and project files, we found no AMOCs submitted for AD 91-18-19. Since there are no AMOCs approved for AD 91-18-19 to approve for this AD, transfer of AMOCs to this AD does not apply.
