Excerpt
Excerpt: On March 21, 1996, a Bell Helicopter Textron, Inc. (BHTI), 205A-1 helicopter, N68HJ, crashed while conducting an external lift operation at Grove Hill, Alabama, after its vertical fin separated from the tail boom just above the intersection of the vertical fin spar and tail boom.? The aircraft was substantially damaged but the pilot was not injured. Examination of the separated pieces of the tail boom at the Safety Board?s materials laboratory revealed that the vertical fin separated from the tail boom as a result of fatigue cracking in the left cap of the vertical fin front spar The fatigue cracking initiated from the first rivet hole above the top of the tail boom. The left side of the vertical fin is normally subject to tensile loading as a result of anti-torque forces produced by the tail rotor. The Safety Board determined the probable cause of that accident to be ?fatigue failure of the vertical fin onward spar in an area that was not accessible to inspection,? and also stated that guidance for inspection of the area where the m e occurred was insufficiently defined by the manufacturer.
