Airworthiness Directives; Daher Aerospace (Type Certificate Previously Held by SOCATA) Airplanes

FAA / Federal Register · 2021-26964

The FAA is adopting a new airworthiness directive (AD) for all Daher Aerospace (type certificate previously held by SOCATA) Model TB 20 and TB 21 airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks on the main landing gear (MLG) legs. This AD requires repetitively inspecting the MLG and performing all applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
