(1) Shoulder Harness
In S/N's 2842001 thru 2842081 only:
(a) Inspect ends and attachment points for condition and security.
(b) Inspect harness web material for condition and wear over its entire length. Particularly
look for wear and fraying where harness web passes in and out of inertial reel. If
excessively worn, replace.
(c) Check inertia reel mechanism by pulling sharply on strap. Verify reel will lock in place
under sudden stress.

stamp of 6/94 thru 8/95, if the seat belt buckle end has an old Piper logo (large
stylized "P") or no logo, and if the seat belt fitting end I.D. tag has a date stamp
of 6/94 thru 8/95.

Replacement belts, fitting end and buckle end, should be ordered under the
same part number(s) found on the suspect seat belts as no new part numbers
were issued. Order the appropriate quantity of: Seat Belt, Fitting End - P/N 564-
867; Buckle End (short) - P/N 564-868; Buckle End (medium) - P/N 564-889;
and/or, Buckle End (long) - P/N 564-862.
c
Check the new seat belts for operation and security, after installation.
d
Make an appropriate logbook entry of compliance with Service Bulletin No. 990.
Pending replacement of the suspect seat belts, the aircraft may be flown, provided
the Pilot-In-Command inspects each seat belt being used for secure positive latching
and that the seat belts are free of any anomalies prior to each flight and during each
use.
