AD 98-12-14

This amendment adopts a new airworthiness directive (AD) that applies to certain AERMACCHI S.p.A. (AERMACCHI) S.205 series and Models S.208 and S.208A airplanes. This AD requires inspecting the flap cable pulley bracket for correct alignment and correcting any misalignment; inspecting the flap control cable for wear (nicks, cuts, frays, etc.), and replacing the flap control pulley bracket and flap control cable if worn. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. The actions specified by this AD are intended to prevent flap control failure, which could result in loss of control of the airplane.

Final rule.

98-12-14 AERMACCHI S.P.A.: Amendment 39-10570; Docket No. 97-CE-146-AD.

Applicability: Models S.205-18/F, S.205-18/R, S.205-20/F, S.205-20/R, S.205-22/R, S.208, and S.208A airplanes, all serial numbers, certificated in any category.

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 (d) 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 100 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished.

To prevent flap control failure which could result in loss of control of the airplane, accomplish the following:

(a) Inspect the flap cable pulley bracket for correct alignment, and if the flap cable pulley bracket is misaligned, prior to further flight, correct any misalignment of the pulley bracket in accordance with the Instructions section of SIAI Marchetti Service Bulletin No. 205B60, dated July 24, 1995.

(b) Inspect the flap control cable for wear (cuts, nicks, frays, etc.), and if wear is found, prior to further flight, replace the flap control cable and flap cable pulley bracket in accordance with the Instructions section of SIAI Marchetti Service Bulletin No. 205B60, dated July 24, 1995.

(c) 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.

(d) An alternative method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be approved by the Manager, Small Airplane Directorate, 1201 Walnut, suite 900, Kansas City, Missouri 64106. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Small Airplane Directorate.

NOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Small Airplane Directorate.

(e) Questions or technical information related to SIAI Marchetti Mandatory Service Bulletin No. 205B60, dated July 24, 1995, should be directed to SIAI Marchetti, Product Support, Via Indipendenza 2, 21018 Sesto Calende (VA), Italy; telephone: +39-331-929117; facsimile: +39-331-922525. This service information may be examined at the FAA, Central Region, Office of the Regional Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106.

(f) The inspections and replacements required by this AD shall be done in accordance with SIAI Marchetti Mandatory Service Bulletin No. 205B60, dated July 24, 1995. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be obtained from SIAI Marchetti, Product Support, Via Indipendenza 2, 21018 Sesto Calende (VA), Italy. Copies may be inspected at the FAA, Central Region, Office of the Regional Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri, or at the Office of the Federal Register, 800 North Capitol Street, NW, suite 700, Washington, DC.

NOTE 3: The subject of this AD is addressed in Italian AD 95-237, dated August 29, 1995.

(g) This amendment becomes effective on July 18, 1998.

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 AERMACCHI S.205 series and Models S.208 and S.208A airplanes was published in the Federal Register as a notice of proposed rulemaking (NPRM) on March 13, 1998 (63 FR 12418). The NPRM proposed to require: inspecting the flap control pulley bracket for alignment; correcting any misalignment; inspecting the flap control pulley cable for wear; and, replacing the bracket and cable if worn. Accomplishment of the proposed actions as specified in the NPRM would be in accordance with SIAI Marchetti Service Bulletin No. 205B60, dated July 24, 1995.

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

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 70 airplanes in the U.S. registry will be affected by this AD, that it will take approximately 4 workhours per airplane to accomplish this action, and that the average labor rate is approximately $60 an hour. Parts cost approximately $150 per airplane. Based on these figures, the total cost impact of this AD on U.S. operators is estimated to be $27,300, or $390 per airplane.

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 atthe location provided under the caption "ADDRESSES".
