PIPER NAVAJO SERVICE MANUAL
6-163. HIGH ALTITUDE GEAR OPERATION.
Should it be necessary to operate the landing gear at
altitudes above 15,000 feet, the landing gear selector may return to its neutral position before the gear door
closing cycle is complete. If this occurs, manual override of the time delay cycle must be used to close the gear
doors.
During gear extension, if the selector returns to neutral at the same time the gears are locked down, and
before the gear doors have had time to close, again select the gear down position and hold the handle down
for an additional 3 to 4 seconds. This allows completion of the door closing cycle.
During gear retraction, if the selector returns to neutral and the gear unsafe light remains lit, again select
the gear up position and hold the handle up for 4 seconds after the gear unsafe light extinguishes. Be sure that
the light has extinguished before exceeding the maximum gear extended speed.
