## Summary

We propose to adopt a new airworthiness directive (AD) for 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 the potential for a spring on the compressor clutch plate to shear the oil cooler inlet-hose due to the close routing of these parts without a protective cover. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
