Background: A
report was received of a fatal accident overseas where
investigation revealed that the tail boom vertical fin had failed
as a result of a fatigue crack that initiated on the left side of
the vertical fin spar cap, and propagated across the cap and the
web. Amendment 1 required a reinforcement modification, while still
requiring a repetitive inspection at increased periodicity.
Amendment 2 introduced the latest revision of the Requirement
document which revised the modification procedures. Amendment 3 is
issued in response to a new JCAB AD, which transfers the inspection
requirements of this Directive to the KHI-BK117 Maintenance Manual.
The original issue of this Airworthiness Directive became effective
on 9 May 1997.
