Summary
We propose to adopt a new airworthiness directive (AD) for all PILATUS Aircraft Ltd. Model PC-7 airplanes. 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 a need to incorporate new revisions into the Limitations section of the FAA-approved maintenance program (e.g., maintenance manual). The limitations were revised to include an emergency fuel control system adjustment test. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
