All Beechcraft 200 series aircraft
The purpose of this Bulletin is to alert operators and maintainers of Beechcraft 200 series aircraft to reported cracking of fuselage frames of these aircraft. It is recommended that operators and maintainers obtain advice from the manufacturer concerning inspection for cracking and acceptable repairs.
CASA has received reports of cracking of rear fuselage frames of several Beechcraft 200 series aircraft. CASA has assessed this problem as potentially serious. CASA has briefed the FAA concerning this problem and understands that the FAA is addressing the problem in cooperation with the manufacturer. Pending possible issue of a mandatory Service Bulletin by the manufacturer or an Airworthiness Directive by the FAA, operators and maintainers are advised to check all 200 series aircraft for this problem. It may become necessary for CASA to issue an Airworthiness Directive to address this problem.
The fuselage damage reported to CASA includes fatigue cracks to skin, stringers and fuselage frames between fuselage stations 326.75 and 337.75 and at the rear pressure bulkhead. The sketch on the following page identifies the regions of fuselage damage.
It is recommended that operators and maintainers inspect all Beechcraft 200 series aircraft, obtaining advice from the manufacturer concerning inspection and acceptable repairs.
