## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Raytheon Aircraft Company (Raytheon) Beech Models 60, A60, and B60 airplanes. The proposed AD would require you to inspect for the existence of any lower forward wing bolts with the Mercury Aerospace trademark, and replace any such bolt with an FAAapproved bolt without this trademark. The proposed 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 the proposed 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.
