Gap Conditions Between Parts Attached with Threaded Fasteners

If a gap condition exists between mating parts where a threaded fastener is to be installed, install
fasteners and associated hardware per subject chapter/section or to buildup noted during removal.
Then, torque to a value 10% of the final torque required plus the friction drag torque.
For example, if Chart 2, Sheet 2, torque is 190 in.-lbs. and the friction drag torque of the nut is 80
in.-lbs. (i.e. - Chart 2, Sheet 2, torque minus Chart 2, Sheet 1, torque), torque to a value of:
Maximum Permissible
Gap Closing Torque
Example:
Accomplish this for all fasteners common to the gapped interface. If no gap exists after
accomplishing the above, finish torquing to final torque. If a gap remains consult your Piper Dealer's
Service Advisor (DSA) for further assistance.
D. After the final torque, apply a slippage mark to the nut or bolt or screw head as applicable.
NOTE: For more details on torquing, refer to FAA AC 43.13-1, latest revision.
