FAA Issues AD for Lear 45 Thrust Reverser

 - July 23, 2014, 3:00 PM

A new airworthiness directive (AD) for the Learjet 45 stems from a report of two cases of premature corrosion on the structural support flange for the engine thrust reverser. The AD requires inspecting for any corrosion, and damage to the sealant; installing sealants and gaskets; and related investigative and corrective action as necessary. The AD is designed to prevent failure of the thrust-reverser structural support, which could result in departure of the thrust reverser from the engine, subsequently resulting in damage to the adjacent support structure and engine controls, airframe structure, and control surfaces. Departing thrust reversers could also result in injury to people on the ground.
