Airworthiness Directives; AERMACCHI S.p.A. Models F.260, F.260B, F.260C, and F.260D Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a new airworthiness directive (AD) that applies to certain AERMACCHI S.p.A. (AERMACCHI) Models F.260, F.260B, F.260C, and F.260D airplanes. This AD requires marking the airspeed indicator to indicate the correct flap operation range and stall speed of the airplane. 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 the airplane from stalling at an airspeed higher than anticipated, which could result in loss of control of the airplane.

DATES: Effective August 1, 1998.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of August 1, 1998.

ADDRESSES: Service information that applies to this AD may be obtained from AERMACCHI, Product Support, Via Indipendenza 2, 21018 Sesto Calende (VA), Italy; telephone: +39-331-929117; facsimile: +39-331- 922525. This information may also be examined at the Federal Aviation Administration (FAA), Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 97-CE-143-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. David O. Keenan, Project Officer, FAA, Small Airplane Directorate, Aircraft Certification Service, 1201 Walnut, suite 900, Kansas City, Missouri 64106; telephone: (816) 426- 6934; facsimile: (816) 426-2169.

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 AERMACCHI Models F.260, F.260B, F.260C, and F.260D airplanes was published in the Federal Register as a notice of proposed rulemaking (NPRM) on April 13, 1998 (63 FR 17969). The NPRM proposed to require marking the airspeed indicator with a black arc to indicate the correct stall speed and flap operation range of the airplane. Accomplishment of the proposed action as specified in the NPRM would be in accordance with SIAI Marchetti S.p.A. Service Bulletin No. 260B54, dated May 28, 1993.

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 60 airplanes in the U.S. registry will be affected by this AD, that it will take approximately 1 workhour per airplane to accomplish this action, and that the average labor rate is approximately $60 an hour. Materials for marking the airspeed indicator can be obtained locally at minimal cost. Based on these figures, the total cost impact of this AD on U.S. operators is estimated to be $3,600, or $60 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 at the location provided under the caption ADDRESSES.

Adoption of the Amendment

Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

   Authority: 49 U.S.C. 106(g), 40113, 44701.

   Sec. 39.13 [Amended]

2. Section 39.13 is amended by adding a new airworthiness directive (AD) to read as follows:

   98-13-09 AERMACCHI S.P.A.: Amendment 39-10597; Docket No. 97-CE- 143-AD.

   Applicability: Models F.260, F.260B, F.260C, and F.260D airplanes, serial numbers 001 through 848, 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 (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 100 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished.

   To prevent the airplane from stalling at an airspeed higher than anticipated, which could result in loss of control of the airplane, accomplish the following:

   (a) Mark the airspeed indicator with a black arc between the numbers 0 and 63.5 in accordance with the Instructions section of SIAI Marchetti S.p.A Service Bulletin No. 260B54, dated May 28, 1993. All other operating ranges on the airspeed indicator are correct.

   Note 2: Although the SIAI Marchetti S.p.A. service bulletin referenced above calls out all of the operating ranges indicated on the airspeed indicator, it is the FAA's intent in this AD to focus only on the flap operating range.

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

   (d) Questions or technical information related to SIAI Marchetti Service Bulletin No. 260B54, dated May 28, 1993, should be directed to AERMACCHI, 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.

   (e) The modification required by this AD shall be done in accordance with SIAI Marchetti Service Bulletin No. 260B54, dated May 28, 1993. 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 AERMACCHI, 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 4: The subject of this AD is addressed in Italian AD 93- 220, dated July 29, 1993.

   (f) This amendment becomes effective on August 1, 1998.

   Issued in Kansas City, Missouri, on June 9, 1998. Michael Gallagher, Manager, Small Airplane Directorate, Aircraft Certification Service.
