## Abstract

We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model 390 airplanes. This AD requires you to inspect the starter-generator to determine the serial number (S/N) and suffix letter, which indicates if the part is improperly shimmed. This AD also requires you to replace any improperly shimmed starter- generator with a properly shimmed starter-generator. This AD results from reports of a manufacturing error where certain starter-generators may have been improperly shimmed. We are issuing this AD to detect and correct improperly shimmed starter-generators, which could result in premature starter-generator failure. This failure could lead to increased chances of dual starter-generator failure on the same flight.
