Airworthiness Directive: Piaggio Model P-180 Flap Transmission Shaft Inspection Requirement
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The FAA has issued a new Airworthiness Directive (AD) targeting specific Baykar Piaggio Aerospace S.p.A. (formerly Piaggio Aviation S.p.A.) Model P-180 airplanes. The directive was triggered by a confirmed report of chafing damage in the flap transmission shafts, which poses an unsafe condition that must be addressed to ensure continued airworthiness. Under this AD, operators are required to inspect the flap transmission shafts for evidence of chafing or physical damage, including surface abrasions, grooves, rubbing tracks, and metallic smears or material transfers. Additionally, specific gap measurements must be taken as part of the inspection protocol. Depending on the findings of the inspection, applicable corrective actions must be carried out. The nature of these corrective actions will vary based on the severity and type of damage discovered during the inspection. Non-compliance with this AD could result in continued degradation of the flap transmission system, potentially leading to loss of flap control and compromising flight safety.
