Piaggio Aero Industries S.p.A. Airplanes
This AD applies to Piaggio Aero Industries S.p.A. P-180 Model P-180 airplanes, serial numbers affected 1002 and 1004 through 1189, certificated in any category.
We are adopting a new airworthiness directive (AD) for 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 the baggage door lockpins not engaging properly and the baggage door open light illuminating when the baggage door is not open, which could lead to the pilot disregarding a valid warning. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions:
(1) If false in-flight BAG DOOR indications have occurred, within 165 hours time-in-service (TIS) after January 17, 2012 (the effective date of this AD) or within the next 60 days after January 17, 2012 (the effective date of this AD), whichever occurs first, do the following actions:
(i) Modify the locking mechanism following the Accomplishment Instructions in Piaggio Aero Industries S.p.A. Service Bulletin No. 80-0223, Revision 1, dated July 31, 2009.
(ii) Inspect the screws on the locking device installed on the door handle for proper tightness and correct as necessary after applying a thread locker following Part D of the Accomplishment Instructions in Piaggio Aero Industries S.p.A. Mandatory Service Bulletin No. 80-0289, Revision 1, dated January 11, 2011.
(2) If false in-flight BAG DOOR indications have not occurred, within 165 hours TIS after January 17, 2012 (the effective date of this AD) or within the next 60 days after January 17, 2012 (the effective date of this AD), whichever occurs first, do the following actions:

Take any necessary corrective actions after applying a thread locker following Part D of the Accomplishment Instructions in Piaggio Aero Industries S.p.A. Mandatory Service Bulletin No. 80-0289, Revision 1, dated January 11, 2011.
