Summary of the Problem.
a. Two Forward Fuel Cell Restraint Panels (P/N 7-31113127-3/-7) manufactured from "black polycar-
bonate" material have been found cracked and/or buckled in FMS aircraft. These black panels were installed
in production of "A" model aircraft PV 833 and subsequent (90-0506 and subsequent) and some "D" model
aircraft. A bulging, pressurized fuel cell may press a cracked panel against flight control components located
immediately above one of the panels. Contact is not deemed sufficient to bind these flight controls, however,
prudent removal of the discrepant panels eliminates any risk. Earlier panels were manufactured from Kevlar
(painted yellow or green) and have exhibited no cracking. Both panel types are listed with identical part num-
bers in the RPTSL.
b. For manpower/downtime and funding impacts, see paragraph 12.
c. The purpose of this TB is to establish a one time inspection to determine whether discrepant "black
polycarbonate" panels are installed and to establish a recurring inspection until the polycarbonate panels are
replaced.
