and subsequent, model T10282()() propeller blades
are life limited when operated above 12,500 pounds
gross weight and must be retired after 9,000 hours
of operation. The life limit begins once the blades
are operated above 12,500 pounds gross weight and
continues regardless of subsequent operating weight.
For those blades on which the total accumulated time in
operation on an aircraft with a gross weight exceeding
12,500 pounds cannot be confirmed, the following
formula will be used to establish an assumed time:
Months from date of STC incorporation X 180 = total
assumed time on subject blades.
** Pilatus PC-7 propeller blades must be retired from
service in accordance with the following schedule:
(a) Aircraft on which Power-On-Spin, Inertia Coupled
Entry, and Snap Roll flight maneuvers are prohibited
must be retired from service when 9795 flight hours
have been acquired.
(b) Aircraft on which Power-On-Spin and Inertia
Coupled Entry flight maneuvers are prohibited must
be retired from service when 4240 flight hours have
been acquired.
(c) Any aircraft, once operated with Snap Roll
maneuvers permitted, must be retired from service
upon acquiring 4240 flight hours.
