CAUTION: DO NOT MOVE THE OVERWING EMERGENCY-EXIT DOOR UP. IF YOU DO, THE HINGES CAN BREAK AND DAMAGE TO THE STRUCTURE CAN OCCUR.

(a) Use the 98A52008509000 SLING-UNIVERSAL,DOORS (104) to carefully lower the overwing emergency-exit door (31) adjacent to the closed position.
1 Do not fully close the overwing emergency-exit door (31).

NOTE: The opening of the overwing emergency-exit door (31) must have a bottom clearance of a minimum of 250 mm (9.84 in.).

(b) Carefully operate the CRANE 50KG (110 LB) to make sure that all three slings of the 98A52008509000 SLING-UNIVERSAL,DOORS (104) are equally straight.
(5) Remove the center hinge (40):
