SUBJECT HEADING:   Airworthiness Directives; Aeromot-Industria Mecanico Metalurgica Ltda. Model AMT-200 Powered Gliders

ACTION:   Final rule

SUMMARY:   This amendment adopts a new airworthiness directive (AD) that applies to certain Aeromot-Industria Mecanico Metalurgica Ltda. (Aeromot) Model AMT-200 powered gliders. This AD requires replacing certain flexible hoses in the engine oil system with flexible hoses with a larger internal diameter. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Brazil. The actions specified by this AD are intended to prevent inefficiency of the engine lubricating system because of ineffective flexible hoses, which could result in an in-flight engine shutdown with consequent loss of powered glider controllability.

DATES:   Effective September 7, 1998. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of September 7, 1998.

ADDRESSES:   Service information that applies to this AD may be obtained from Grupo Aeromot, Aeromot-Industria Mecanico Metalurgica Ltda., Av. das Industrias-1210, Bairro Anchieta, Caixa Postal 8031, 90200-Porto Alegre-RS, Brazil. This information may also be examined at the Federal Aviation Administration (FAA), Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 98-CE-27-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. Curtis Jackson, Aerospace Engineer, FAA, Atlanta Aircraft Certification Office, One Crown Center, 1895 Phoenix Blvd., suite 450, Atlanta, Georgia 30349; telephone: (770) 703-6083; facsimile: (770) 703-6097.

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 Aeromot Model AMT-200 powered gliders was published in the Federal Register as a notice of proposed rulemaking (NPRM) on April 30, 1998 (63 FR 23685). The NPRM proposed to require replacing any engine oil system hose, part number 10702, 10703, or 10704, with a hose with a larger internal diameter, part number 10706, 10707, or 10708. Accomplishment of the proposed action as specified in the NPRM would be in accordance with Aeromot Service Bulletin B.S. No. 200-79-036, Issue Date: January 30, 1997.

The NPRM was the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Brazil.

Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were received on the proposed rule or 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 18 powered gliders in the U.S. registry will be affected by this AD, that it will take approximately 7 workhours per powered glider to accomplish the replacements, and that the average labor rate is approximately $60 an hour. Based on these figures, the total cost impact of this AD on U.S. operators is estimated to be $7,560, or $420 per powered glider.

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".
