Action
Notice of proposed rulemaking (NPRM).
Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Daher Aerospace (type certificate previously held by SOCATA) Models 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 proposed AD would require repetitively inspecting the MLG and performing all applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
