What it does

The FAA is adopting a new airworthiness directive (AD) for certain Baykar Piaggio Aerospace S.p.A. (type certificate previously held by Piaggio Aviation S.p.A.) (Piaggio) Model P-180 airplanes. This AD was prompted by a report of chafing in the flap transmission shafts. This AD requires inspecting the flap transmission shaft for chafing or any damage (surface abrasions, grooves or rubbing tracks, and metallic smears or transfers), measuring specific gaps, and, depending on findings, accomplishing applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
