SEAT STOP
SECTION 1
GENERAL
A secondary seat stop installation is provided for the pilot's seat to
prevent the seat from inadvertently sliding aft beyond the adjusted flight
position if it is not securely locked by the standard seat lock.
The secondary seat stop installation (see Figure 1) consists of a seat
stop lever assembly mounted to the inboard seat rail and floor structure
and a stop plate attached to the inboard side of the pilot's seat pedestal
or frame. The stop lever rotates and is spring-loaded to maintain contact
with the seat rail, and thereby serves as a secondary seat stop to prevent
rearward movement of the seat beyond the stop. Either the aft seat roller
housing or the tabs which protrude from the seat stop plate will contact
the stop lever, preventing additional rearward movement.
the seat position selected by the seat occupant, the secondary stop may
be slightly aft of the entire seat or it may be in a position forward of the
aft roller or one of the tabs on the seat stop plate when the seat is
adjusted to the desired flight position.
positioned, rearward seat travel will be restricted in the event the seat
occupant fails to lock the seat in position by normal means.
rearward seat movement is desired for additional leg room or when
exiting the airplane, the stop lever can be manually rotated to the
UNLATCH position while the normal seat lock release is simultaneously
operated. This will allow clearance between the stop lever and the seat
rail for passage of the seat roller housing or seat stop plate tabs as the
seat is moved aft.
