## Summary

We propose to adopt a new airworthiness directive (AD) for Pacific Aerospace Limited Models FU24-954 and FU24A-954 airplanes modified with an unapproved hopper lid modification. 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:

Investigation of a recent Cresco 08-600 accident identified a risk of the hopper lid interfering with the opening of the canopy in the event of an emergency landing. The pilot was prevented from opening the canopy by the hopper lid in the fully forward open position. This AD is issued due to the fact that the hopper lid installation on the accident aircraft was an unapproved modification and the Fletcher FU24 hopper installation is a similar design to the Cresco 08-600.

The proposed AD would require actions that are intended to address the unsafecondition described in the MCAI.
