ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12/47E airplanes. This AD was prompted by a report that, during an engine start on the ground, the airplane battery voltage dropped to a value that resulted in an avionic system shutdown.

The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective September 3, 2026. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of September 3, 2026.
