## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 93-25-07, which applies to Raytheon Aircraft Company (Raytheon) Beech 100, 200, and 300 series airplanes. AD 93-25-07 currently requires you to repetitively inspect the fuselage stringers for cracks and modify at certain times depending on the number of cracked stringers. This proposed AD is the result of FAA's policy (since 1996) to not allow airplane operation when known cracks exist in primary structure. The fuselage structure is considered primary structure and operation is currently allowed for a certain period of time if less than five fuselage stringers are cracked. Consequently, this proposed AD would retain the inspection and modification requirements of AD 93-25-07, but would require you to repair any cracked fuselage stringers. We are issuing this proposed AD to detect and correct any cracked fuselage stringers in the rear pressure bulkhead area, which could result in structural damage to the fuselage. Thisdamage could lead to failure of the fuselage with potential loss of control of the airplane.
