MORE Company currently has eight (8) FAA-approved Supplemental Type Certificates (STCs) for the PT6A engine.  Each were developed to customize the inspection methods for each individual engine model.   The MORE STC's are eligible for acceptance as part of an Approved Aircraft Inspection Program (AAIP) for a section 91.409(f) (4) program that also includes the airframe, avionics, propeller, and accessories.

The FAA has issued a Flight Standards Information Bulletin for Airworthiness (FSAW) Bulletin Number FSAW 05-07.  This bulletin alerts all aviation safety inspectors (ASI) to the availability of a CD-ROM training program that provides an overview of the MORE STC's that are used on PT6A engines.  FAA inspectors can gain access to the training program from the FAA Intranet at:
