Airworthiness Directives; Mooney Aircraft Corporation Models M20B, M20C, M20D, M20E, M20F, M20G, M20J, M20K, M20L, M20M, and M20R Airplanes

Краткое содержание

This amendment adopts a new airworthiness directive (AD) that applies to certain Mooney Aircraft Corporation (Mooney) Models M20B, M20C, M20D, M20E, M20F, M20G, M20J, M20K, M20L, M20M, and M20R airplanes. This AD requires inspecting the aileron control links for the installation of a reinforcing gusset; and, if no gusset is installed, repetitively inspecting the aileron control links (left-hand and right-hand) for cracks. If cracks are found, this AD requires replacing the aileron control links with parts of improved design. This AD is the result of service difficulty reports (SDR's) on the aileron control links and reported failures of the aileron control links. The actions specified by this AD are intended to detect and correct cracked aileron control links, which could result in loss of aileron control with consequent loss of control of the airplane.
