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:
It has been evidenced in-service that aileron trim actuator and rod spring lever attachment bracket--between frame 18 and 19 LH--on some aircraft may present loose rivets. If left uncorrected, this condition could lead to the separation of the attachment bracket which could result in loss of aileron trim and loss of artificial force feedback, and consequent reduced controllability of the airplane.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
