Airworthiness Directives; Raytheon Aircraft Company Beech Models 60, A60, and B60 Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Beech Models 60, A60, and B60 airplanes. This AD requires you to inspect for the existence of any lower forward wing bolts with the Mercury Aerospace trademark, and replace any such bolt with an FAA-approved bolt without this trademark. This AD is the result of a report that wing bolts supplied by Mercury Aerospace may not meet the required Rockwell hardness specifications. The actions specified by this AD are intended to detect and correct wing bolts that do not meet strength requirements. Continued airplane operation with such bolts could result in fatigue failure of the bolts with consequent separation of the wing from the airplane.
