6.7 GTX 33ES Transponder Removal & Replacement
Removal:
1. Make sure all airplane electrical power is disconnected.
2. Remove the PFD.
3. Unlock the GTX 33 handle by loosening the Phillips screw on the handle.
4. Pull the handle upward to unlock the GTX 33. Gently remove the unit from the rack.
5. Place protective caps on the GTX 33 electrical connectors and rack connectors.
6. Remove the unit from the airplane.
Reinstallation:
1. Remove the protective caps from the GTX 33 electrical connectors and rack connectors.
Visually inspect the electrical connectors to make sure there are no bent or damaged
pins. Repair any damage.
NOTE
A handle-lock mechanism is used to guide and lock the LRU into place.
The handle has a locking stud that engages a dogleg-shaped track on
the LRU rack. After engaging the dogleg, the handle can be pushed
down and locked. This action seats the LRU against the rear plate and
connectors. A single Phillips screw is used to fasten the lever to the LRU
body. Gently insert the GTX 33 into its rack. The handle should engage
the dogleg track.
CAUTION
Some pressure is required to seat the LRU and lock the handle. The unit
should be gently worked into position using the lever. Do not use
excessive force inserting the LRU. If the LRU binds or is caught, stop
and remove it. Check and make sure the rear plate and connectors are
floating freely in the LRU rack before attempting to re-install.
2. Push down on the GTX 33 handle to lock the unit into the rack.
3. Lock the handle to the GTX 33 body using the Phillips screw.
4. Reinstall the PFD.
5. No software or configuration loading is required if the removed GTX is reinstalled. This
does not include units that were returned for repair as their software and configuration
files are deleted during the repair testing process. Proceed to Section 7.1.1.
6. If a new, repaired, or exchange GTX is installed, the correct software and configuration
files must be loaded to the unit. See Section 3.7 then continue to Section 7.1.1.
