2011-24-01: Landing Gear

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 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] 0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2011-24-01 Piaggio Aero Industries S.p.A.: Amendment 39-16865; Docket No. FAA-2011-0954; Directorate Identifier 2011-CE-028-AD. (a) Effective Date This airworthiness directive (AD) becomes effective December 22, 2011. (b) Affected ADs None. (c) Applicability This AD applies to PIAGGIO AERO INDUSTRIES S.p.A Model PIAGGIO P-180 airplanes, all serial numbers, that are: (1) Certificated in any category; and (2) Have any of the following main landing gear (MLG) actuators installed: (i) Messier-Dowty Part Number (P/N) 114346003 (left hand side): withserial number (S/N) SA0706275, SA0706276, SA0706726, SA0706727, SA0706728, SA0706729, SA0706738, SA0706739,SA0707243, SA0707864, or SA0708072; or (ii) Messier-Dowty P/N 114346004 (right hand side): with S/N SA0703800, SA0703801, SA0705520, SA0706219, SA0706960, or SA0706961. (d) Subject Air Transport Association of America (ATA) Code 32: Landing Gear. (e) Reason The mandatory continuing airworthiness information (MCAI) states: Some lock sleeves (part number (P/N) 114146681), which were installed in some Main Landing Gear (MLG) actuators, had been incorrectly manufactured. If left uncorrected, this condition could lead to failure to lock the MLG actuator or to its unlock from the correct position, with subsequent possible damage to the aeroplane and injuries to occupants during landing. This AD requires replacing defective MLG actuators with serviceable ones. Defective actuators can be repaired by the manufacturer and identified with the ``P180-32-29'' marking on the name plate. (f) Actions and Compliance Unless already done, do the following actions: (1) Within 25 hours time-in-service (TIS) after December 22, 2011 (the effective date of this AD), inspect both installed MLG actuators to determine if an affected P/N and S/N actuator is installed. (2) If any affected P/N and S/N actuator is identified with the ``P180-32-29'' marking on the name plate, no further action is required by this AD on that actuator. (3) If one or both affected MLG actuators are not identified with the ``P180-32-29'' marking on the name plate, before reaching a total of 3,000 landings on the actuator or within the next 150 landings after December 22, 2011 (the effective date of this AD), whichever occurs later, replace the affected actuator(s) with serviceable parts following Part B of the Accomplishments Instructions of Piaggio Aero Industries S.p.A. Mandatory Service Bulletin No. 80-0304, dated July 9, 2010. If landing data is not available, the use of a one-to-one landing to flight hour conversion must be applied (example: 3,000 landings equal 3,000 hours TIS). (4) After December 22, 2011 (the effective date of this AD), do not install any MLG actuator having an affected P/N and S/N, unless it is identified with the ``P180-32-29'' marking on the name plate. Note 1: There is a warranty expiration date for the replacement of the actuators. The FAA recommends owners/operators that have affected main landing gear actuators contact the manufacturer immediately and replace the actuators under warranty. FAA AD Differences Note 2: This AD differs from the MCAI and/or service information as follows: None. (g) Other FAA AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, a federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subjectto a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number.
