(3) Firmly support the TE fairing door and use the push/pull gage to slowly push against the center of the door (and plate). The pressure relief door should release when gage indicates 85-105 pounds.
NOTE: Make sure that you apply the force to the center of the door
____
perpendicular to door surface.
S 905-058
CAUTION: REPLACE OR REPAIR A DOOR WHICH DOES NOT RELEASE IN THE LIMIT.
_______ DAMAGE CAN OCCUR TO TE FAIRING DOOR IF PRESSURE RELIEF DOORS ARE RESTRAINED DURING EXCESSIVE PRESSURE.
(4)
If release load, as measured by push/pull gage, is not within limits, replace all four studs and spring clips or replace pressure relief door and frame. Repeat the check.
S 015-060
(5)
If release load, as measured by push/pull gage, is within limits, close the pressure relief door.
S 415-061
(6)
Close the TE fairing doors (AMM 54-62-00/201).

Turn the torque wrench to find the torque that is necessary to release the latch.
S 725-072
(4)
Remove the torque adapter tool.

(5)
Measure the distances Lw and D. Calculate the correct torque values for the necessary release load (Fig. 501).
S 725-074
(6)
Compare the calculated torque with the torque required range.
S 825-080
(7)
If release load, as measured by the torque wrench, is not in limits, repair or replace the pressure relief door and do the check again.
S 865-076
(8)
If the release load is within the limits, close the door
(AMM 54-62-00/201).
D. TE FAIRING DOOR SPRING LOADED TOGGLE LATCHES; Do this check with the push/pull guage (alternative to B71044-10).
S 015-062
(1)
Open the TE fairing doors (AMM 54-62-00/201), if not already open.
S 495-063
(2)
Make sure the end of the push pull gage is protected to prevent damage to the pressure relief door.
S 725-064
(3)
Firmly support the TE fairing door and use the dial push/pull gage to slowly push against the upper or lower aft mounting fastener of the latch mechanism. The pressure relief door should release when the gage indicates 90-110 pounds.
NOTE: Make sure force applied to the aft mounting fastener of
