Airworthiness Directive · Amendment 39-17757 · Flight controls
Piaggio Aero Industries S.P.A Airplanes
This AD applies to Piaggio Aero Industries S.P.A Model P-180 airplanes, manufacturer serial numbers 1002 and 1004 through 1231, certificated in any category.
We are adopting a new airworthiness directive (AD) for certain Piaggio Aero Industries S.P.A Model P-180 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as insufficient clearance between one of the horizontal stabilizer end ribs and the corresponding elevator horn. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions as specified in paragraphs (f)(1) through (f)(3) of this AD:
(1) Within the next 200 hours time-in service (TIS) after April 1, 2014 (the effective date of this AD) or within the next 12 months after April 1, 2014 (the effective date of this AD), whichever occurs first, measure the clearances between the horns of the elevator and the end ribs of the horizontal stabilizer (HS) on left-hand (LH) and right-hand (RH) sides following Part A of the Accomplishment Instructions in Piaggio Aero Industries S.P.A. Mandatory Service Bulletin No.: 80-0381, Rev. 0, dated May 2, 2013.
(2) If the clearance is less than 5 mm on the HS LH or RH side during the measurement as required by paragraph (f)(1) of this AD, before further flight, rework the affected elevator to restore the required minimum clearance between the horn of the elevator and the end rib of the horizontal stabilizer following Part B of the Accomplishment Instructions in Piaggio Aero Industries S.P.A. Mandatory Service Bulletin No.: 80-0381, Rev. 0, dated May 2, 2013.
(3) Within 30 days after accomplishment of the measurement as required by paragraph (f)(1) of this AD, report the results to Piaggio Aero Industries S.P.A. following Part C of the Accomplishment Instructions in Piaggio Aero Industries S.P.A. Mandatory Service Bulletin No.: 80-0381, Rev. 0, dated May 2, 2013.
