Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from 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:
One occurrence has been reported where a maintenance operation had been performed on the elevator controls, and bellcrank * * * located in the Right Hand MLG (main landing gear) wheel well was mistakenly installed upside down. This discrepancy and improper installation caused an unexpected 5[deg] positioning offset of the elevator control surfaces leading to a hazardous condition on landing, [involving] the pilot being unable to flare the aircraft as needed * * * [which resulted in a hard landing].
The unsafe condition is reduced controllability of the airplane. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
