## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This proposed AD was prompted by a report that electronic circuit breakers (ECBs) were found in a locked state after maintenance, but before flight. This proposed AD would require revising the airplane flight manual to incorporate a procedure to check for the ECB status. The FAA is proposing this AD to address the unsafe condition on these products.
