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:
To prevent the rudder trim tab upper pivot hole in the rudder rib flogging out, which may lead to aerodynamic flutter and possible loss of aircraft control * * *
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
