3. Elevator Interchangeability
A. Aluminum Elevator to Graphite Elevator
(1)
Remove aluminum elevator (Ref 27-31-11).
NOTE: Point of interchangeability is the interface of the balance panel and aft balance panel hinge. The hinge is detached from the balance panel and retained with the replaced elevator. A new hinge must be fitted to the replacement elevator prior to installation of the elevator.
(2)
Retain nuts and bolts for subsequent installation, discard all washers.
(3)
Install aft balance panel hinge on elevator nose and install graphite elevator (Ref 27-31-12) with existing hardware except all washers, bonding jumpers, and bonding jumper hardware should be replaced with new hardware.
(4)
Adjust and test elevator and tab per 27-31-0 A/T.
B. Graphite Elevator to Aluminum Elevator
(1)
Remove graphite elevator (Ref 27-31-12).
NOTE: Point of interchangeability is the interface of the balance panel and aft balance panel hinge. The hinge is detached from the balance panel and retained with the replaced elevator. A new hinge must be fitted to the replacement elevator prior to installation of the elevator.
(2)
Retain hardware for subsequent installation.
(3)
Install aft balance panel hinge on elevator nose and install aluminum elevator (Ref 27-31-11) with existing hardware except delete shims from No. 1 hinge bearing bolt.
(4)
Adjust and test elevator and tab per 27-31-0 A/T.
4. Elevator Tab Interchangeability
A. General
(1) The elevator tabs are balanced into the elevator system by adding or removing tab adjust weights on the elevator nose in balance bay No. 1. The number of adjust weights required is a function of tab part number and tab weight. The data plate on each tab is stamped with the tab weight and the number of adjustment weights required. When replacing an elevator tab, the number of tab weights installed on the elevator nose must agree with the number called for on the tab data plate. If data plate is missing or if tab weight is changed (due to structural changes or repainting), see chapter 51 of the structural repair manual for tab adjust weight requirement.
B. Equipment and Materials
(1)
Rigging Pin E-5 - 0.309/0.311-inch diameter, 6.7 +0.25 inches long (MS20392-4)
