NOTE
If the information contained in the following
conditional inspection does not fully reflect the
occurrence or if additional information or clarification
is required, please contact Product Support
Engineering for assistance.
NOTE
Sudden stoppage conditional inspection is to be
accomplished after main or tail rotor blade strike or
any drive system incident which inhibits free rotation
of the drive system.
Sudden stoppage is defined as any rapid
deceleration of the drive system whether caused by
seizure within the helicopter transmission or by
contact of the main or tail rotor blades with the
ground, water, snow, dense vegetation, or other
object of sufficient inertia to cause rapid
deceleration. Tail rotor blade damage, when caused
by striking some object sufficiently to require blade
replacement, is considered sudden stoppage.
