Airworthiness Directives; Raytheon Aircraft Company Models C90A, B200, B200C, B200T, B200CT, 300, B300, B300C, and A200CT Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

SUMMARY: This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Raytheon Aircraft Company (Raytheon) Models C90A, B200, B200C, B200T, B200CT, 300, B300, B300C, and A200CT airplanes. The proposed AD would require installing a filter element in the landing gear hand pump suction line. The proposed AD is the result of reports of the potential for debris to enter the landing gear hand pump and interfere with its operation, which could prevent the nose landing gear from being extended manually. Two occurrences were reported of nose landing gear collapse after manual extension. The actions specified by the proposed AD are intended to prevent the inability to extend the landing gear with the hand pump caused by debris entering the landing gear hand pump, which could result in passenger injury or damage to the airplane if manual operation of the landing gear failed.

DATES: Comments must be received on or before March 8, 1999.

ADDRESSES: Submit comments in triplicate to the Federal Aviation Administration (FAA), Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 98-CE-104-AD, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106. Comments may be inspected at this location between 8 a.m. and 4 p.m., Monday through Friday, holidays excepted.

Service information that applies to the proposed AD may be obtained from the Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201- 0085. This information also may be examined at the Rules Docket at the address above.

FOR FURTHER INFORMATION CONTACT: Mr. Paul DeVore, Aerospace Engineer, FAA, Wichita Aircraft Certification Office, 1801 Airport Road, Mid- Continent Airport, Wichita, Kansas 67209; telephone: (316) 946-4142; facsimile: (316) 946-4407.

Availability of NPRMs

Any person may obtain a copy of this NPRM by submitting a request to the FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 98-CE-104-AD, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106.

Discussion

The FAA has received reports of the potential for debris to enter the landing gear hand pump and interfere with its operation on certain Raytheon Models C90A, B200, B200C, B200T, B200CT, 300, B300, B300C, and A200CT airplanes. This could prevent the nose landing gear from being properly extended manually. Two occurrences were reported of nose landing gear collapse after manual extension.

This condition, if not corrected in a timely manner, could result in the inability to extend the landing gear with the hand pump with consequent passenger injury or damage to the airplane if manual operation of the landing gear failed.

Relevant Service Information

Raytheon has issued Mandatory Service Bulletin SB 32-3073, Revision 1, Issued: March, 1998, Revised: July 1998. This service bulletin includes procedures for installing a filter element in the landing gear hand pump suction line.

The FAA's Determination

After examining the circumstances and reviewing all available information related to the incidents described above, the FAA has determined that AD action should be taken to prevent the inability to extend the landing gear with the hand pump caused by debris entering the landing gear hand pump. This could result in passenger injury or damage to the airplane if manual operation of the landing gear failed.

Explanation of the Provisions of the Proposed AD

Since an unsafe condition has been identified that is likely to exist or develop in other Raytheon Models C90A, B200, B200C, B200T, B200CT, 300, B300, B300C, and A200CT airplanes of the same type design, the FAA is proposing AD action. The proposed AD would require installing a filter element in the landing gear hand pump suction line. Accomplishment of the proposed action would be required in accordance with the service information previously referenced.

Cost Impact

The FAA estimates that 991 airplanes in the U.S. registry would be affected by the proposed AD, that it would take approximately 5 workhours per airplane to accomplish the proposed action, and that the average labor rate is approximately $60 an hour. Raytheon will give warranty credit for parts until July 31, 1999. Based on these figures, the total cost impact of the proposed AD on U.S. operators is estimated to be $297,300, or $300 per airplane.

Regulatory Impact

The regulations proposed herein would not have substantial direct effects 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. Therefore, in accordance with Executive Order 12612, it is determined that this proposal would not have sufficient federalism implications to warrant the preparation of a Federalism Assessment.

For the reasons discussed above, I certify that this action (1) is not a ``significant regulatory action'' under Executive Order 12866; (2) is not a ``significant rule'' under DOT Regulatory Policies and Procedures (44FR 11034, February 26, 1979); and (3) if promulgated, 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. A copy of the draft regulatory evaluation prepared for this action has been placed in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.

   Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

   Compliance: Required within the next 200 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished.

   To prevent the inability to extend the landing gear with the hand pump caused by debris entering the landing gear hand pump, which could result in passenger injury or damage to the airplane if manual operation of the landing gear failed, accomplish the following:

   (a) Install a filter element in the landing gear hand pump suction line, in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Raytheon Mandatory Service Bulletin SB 32-3073, Revision 1, Issued: March, 1998, Revised: July 1998.

   (b) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished.

   (c) An alternative method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be approved by the Manager, Wichita Aircraft Certification Office (ACO), 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Wichita ACO.

   Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Wichita ACO.

   (d) All persons affected by this directive may obtain copies of the document referred to herein upon request to the Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201-0085; or may examine this document at the FAA, Central Region, Office of the Regional Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106.

   Issued in Kansas City, Missouri, on December 28, 1998. Marvin R. Nuss, Acting Manager, Small Airplane Directorate, Aircraft Certification Service.
