757 MAINTENANCE MANUAL
 INBOARD TRAILING EDGE FLAP - ADJUSTMENT/TEST
____________________________________________
 1.  General
_______
 A.  This procedure contains the adjustment and test of the inboard trailing edge (TE) flap. The adjustment and test is done while the aft flap is attached to the main flap, with the flap carriages and aft flap linkages installed.
 B.  The rigging dimensions in this procedure represent rigging the flaps with the wings in the unloaded condition (without engines or fuel weight on the wings). That is the configuration that most closely resembles the in-flight deflection of the wing.
 C.  For a in-service airplane the flaps are usually rigged with the engines installed, on jacks or gears, and with fuel weight on the wings. Regardless of this difference, the rigging dimensions given in this procedure are still the target dimensions for the rigging of the airplane in any configuration.
 NOTE: If the best rigging dimension you can obtain is not within
____ the limit, refer to the tables in this procedure to find the limits for a particular airplane configuration.
