## 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:

Three instances have occurred in which the aircraft took off with pre-mod 6/1676 flight control gust locks still installed, sometimes with disastrous results.

Based on preliminary investigation, the FAA and National Transportation Safety Board (NTSB) believe that an attempted takeoff with the gust locks installed could be the cause of a recent accident in Hyannis, Massachusetts. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
