Verification Method
Operational Check—Once weight is removed and NLG doors are reengaged, retract NLG. Verify 7.5 amp NLG fuse does not blow and that the NLG doors are fully closed. If fuse blows or gear doors are not closed completely, adjust doors per Aft Nose Landing Gear (NLG) Door Mechanism Removal, Installation, and Rigging.
