SITUATION
The seat leather upholstery detaches from the front of the thigh support (aka knee bolster) of either front
seat.
CAUSE
The metal retainer clips on the thigh support are too loose. The clips don’t exert enough pressure on the
plastic retainer on the edge of the seat leather upholstery, so that the upholstery can separate from the
seat’s thigh support frame.
Refer to the Procedure section steps 2, 3, 4 for the root cause of the loose upholstery.
CORRECTION
Inspect the seat leather upholstery for damage. If no damage is found-
Reinstall upholstery onto the metal retainer clips
Bend the clips to exert more force on the plastic retainer. If the clips are damaged, then replace
the carrier
thigh support bracket.
PROCEDURE
1. Move the seat to the following position for access:
-Seat bottom all the way backwards.
-Seat bottom all the way upwards
-Fully extend the thigh support
Use a flashlight to inspect underneath the thigh support:
Is the seat leather upholstery damaged?
YES – Replace the damaged upholstery as needed (refer to ISTA/AIR Group 52 for the applicable repair instructions)
NO – Check under the seat to see if the upholstery is properly retained under the 5 metal clips
Bend the 5 metal clips as needed to retain the upholstery as shown below in step 6.
