Industrie Aeronautiche e Meccaniche Model Piaggio P-180 Airplanes
Superseded. A later AD replaced this one: AD 2000-07-11 R1. Comply with the one in force.
Model Piaggio P-180 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.
This amendment adopts a new airworthiness directive (AD) that applies to all Industrie Aeronautiche e Meccaniche (I.A.M.) Model Piaggio P-180 airplanes. This AD requires repetitively inspecting the brake assembly rods and tubings for wear or damage, and replacing any worn or damaged parts. 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 brake hydraulic fluid from leaking because of the brake assembly rods contacting the brake valve tubing, which could result in the inability to adequately stop the airplane during ground operations.
To prevent the brake hydraulic fluid from leaking because of the brake assembly rods contacting the brake valve tubing, which could result in the inability to adequately stop the airplane during ground operations, accomplish the following:
(a) Within the next 150 hours time-in-service (TIS) after the effective date of this AD, and thereafter at intervals not to exceed 150 hours TIS, inspect the brake system assembly for wear or damage. Accomplish the inspection in accordance with the Accomplishment Instructions in Piaggio Service Bulletin (Mandatory) No.: SB-80-0107, Original Issue: April 30, 1999.
(b) If any worn or damaged parts are found during any inspection required by this AD, prior to further flight, replace the parts in accordance with the appropriate maintenance manual. The repetitive inspections required by paragraph (a) of this AD still apply after replacing any worn or damaged parts.
