184.108.40.206 Driver's hatch. To determine conformance to 220.127.116.11, a force gage shall be
attached to the driver's hatch when it is in the closed position and the hatch shall be pulled to the
open position and back to closed position. The force shall be as specified. With the hatch in a
closed position, the force required to lock the driver's hatch cover shall be measured with a force
gage attached to the end of the locking lever and shall be as specified.
4.6.l3.2 Driver's escape hatch. To determine conformance to 3.4.l2.2, the driver's escape
hatch shall be checked by attaching a force gage to the handle at the point specified, releasing the

various forces for hatch operation shall be measured as specified.
126.96.36.199 Cupola hatch. To determine conformance to 188.8.131.52, using a force gage the
breakaway forces shall be verified for the directions specified. All characteristics shall be within
the limits specified.
184.108.40.206 Driver's seat. To determine conformance to 220.127.116.11, each driver's seat lever shall
be actuated and the seat shall move forward, backward and vertically as appropriate. A force
gage shall be attached to each lever as specified and the force required to actuate shall be
measured. All sliding parts and operating contact surfaces shall be examined for absence of
18.104.22.168 Gunner's seat. To determine conformance to 22.214.171.124, the gunner's seat (no load)

126.96.36.199 Commander's platform seat. To determine conformance to 188.8.131.52, the platform
(no load) shall be slid through its full range, locked and unlocked, and checked for binding and
interference. The seat, also with no load, shall be checked for operability through its range.
184.108.40.206 Loader's seat. To determine conformance to 220.127.116.11, the loader's seat shall be
pulled to the seated position and then released to see if it returns to the vertical position.
