DOCKET NUMBER:   96-CE-60-AD

AMENDMENT:   39-11129

AD NUMBER:   97-15-13 R2

SUBJECT HEADING:   Airworthiness Directives; Raytheon Aircraft Company Beech Models 1900, 1900C, and 1900D Airplanes

ACTION:   Final rule

SUMMARY:   This amendment revises Airworthiness Directive (AD) 97-15-13 R1, which currently requires installing lubrication fittings in the airstair door handle and latch housing mechanisms on certain Raytheon Aircraft Company (Raytheon) Beech Models 1900, 1900C, and 1900D airplanes. Since issuance of AD 97-15-13 R1, Raytheon has revised the applicable service information to correct the reference to the number of parts each owner/operator of the affected airplanes should order and to change an incorrect reference to a maintenance manual. This AD retains the actions of AD 97-15-13 R1, and incorporates the revised service bulletin into the AD. The actions specified by this AD are intended to continue to prevent moisture from accumulating and freezing in the airstair door handle and latch housing, which could result in the door freezing shut and passengers not being able to evacuate the airplane in an emergency situation.

DATES:   Effective May 28, 1999. The incorporation by reference of Raytheon Mandatory Service Bulletin SB.2572, Issued: July, 1996; Revision No. 1, May, 1998, as listed in the regulations is approved by the Director of the Federal Register as of May 28, 1999. The incorporation by reference of Raytheon Mandatory Service Bulletin No. 2572, Issued: July, 1996, as listed in the regulations was previously approved by the Director of the Federal Register as of September 22, 1997 (62 FR 49426).

ADDRESSES:   Service information that applies to this AD may be obtained from the Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201-0085. This information may also be examined at the Federal Aviation Administration (FAA), Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 96-CE-60-AD, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106; or at the Office of the Federal Register, 800 North Capitol Street, NW, suite 700, Washington, DC.

FOR FURTHER INFORMATION CONTACT:   Mr. Steven E. Potter, Aerospace Safety Engineer, FAA, Wichita Aircraft Certification Office, 1801 Airport Road, Mid-Continent Airport, Wichita, Kansas 67209; telephone: (316) 946-4124; facsimile: (316) 946-4407.

SUPPLEMENTARY INFORMATION:  
Events Leading to the Issuance of This AD
A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Raytheon Beech Models 1900, 1900C, and 1900D airplanes was published in the Federal Register as a notice of proposed rulemaking (NPRM) on October 9, 1998 (63 FR 54393). The NPRM proposed to revise AD 97-15-13 R1, Amendment 39-10131 (62 FR 49426, September 22, 1997), by incorporating updated service information into the AD. AD 97-15-13 R1 currently requires installing lubrication fittings in the airstair door handle and latch housing mechanisms on certain Raytheon Beech Models 1900, 1900C, and 1900D airplanes.

Accomplishment of the actions of AD 97-15-13 R1 is required in accordance with Raytheon Mandatory Service Bulletin No. 2572, Issued: July, 1996.

Accomplishment of the proposed installations would be required in accordance with Raytheon Mandatory Service Bulletin No. 2572, Issued: July, 1996; or Raytheon Mandatory Service Bulletin SB.2572, Issued: July, 1996; Revision No. 1, May, 1998.

Interested persons have been afforded an opportunity to participate in the making of this amendment. One comment was received in favor of the NPRM and no comments were received on the FAA's determination of the cost to the public.

The FAA's Determination
After careful review of all available information related to the subject presented above, the FAA has determined that air safety and the public interest require the adoption of the rule as proposed except for minor editorial corrections. The FAA has determined that these minor corrections will not change the meaning of the AD and will not add any additional burden upon the public than was already proposed.

Cost Impact
The FAA estimates that 408 airplanes in the U.S. registry will be affected by this AD, that it will take approximately 14 workhours per airplane to accomplish the installation, and that the average labor rate is approximately $60 an hour. Parts cost approximately $50 per airplane. Based on these figures, the total cost impact of this AD on U.S. operators is estimated to be $363,120, or $890 per airplane. This figure is based on the presumption that no owner/operator of the affected airplanes has accomplished the required installation.

This AD requires the same actions as AD 97-15-13 R1. The only difference is reference to Raytheon Mandatory Service Bulletin SB.2572, Issued: July, 1996; Revision No. 1, May, 1998. Therefore, this AD imposes no additional cost impact upon U.S. owners/operators of the affected airplanes than is already required by AD 97-15-13 R1. Regulatory Impact

The regulations adopted herein will 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 final rule does 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 (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. A copy of the final evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption "ADDRESSES".

(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.
