HYDRAULIC POWER (Cont.)
C. Troubleshooting
– CAUTION –
If equipped with automatic gear extender, prior to starting any
investigation of the hydraulic system, place airplane on jacks.
With airplane on jacks, pull the emergency extension lever up
and latch in override position. This is required to prevent the
buildup of unnecessary pressure on actuating cylinders and
connecting hydraulic lines when gear is raised or lowered
manually. Failure to comply with this procedure could result
in the buildup of sufficient pressure to unlock the downlock
mechanism allowing gear to collapse when wing jacks are
removed. Prior to removing airplane from jacks, push emergency
lever down, turn on master switch and select gear down.
Observe that all three green lights indicating the landing gear
is down and locked are energized. Turn master switch off.
Malfunctions in the hydraulic system will result in failure of the landing gear to operate properly.
and suggests a remedy for the trouble involved. A hydraulic system operational check may be conducted
ing the cause. Hydraulic system troubles are not always traceable to one cause. It is possible that a
malfunction may be the result of more than one difficulty within the system. Starting first with the
most obvious and most probable reasons for the trouble, check each possibility and, in turn, by process
of elimination, isolate the troubles.
– NOTE –
If equipped with a Prestolite hydraulic pump that is found to
be faulty, requiring disassembly, it is recommended it be
repaired by an accredited overhaul facility. If equipped with an
Oildyne hydraulic pump that is found to be faulty, pump must
be replaced, or returned to Piper Aircraft, via the local Piper
distributor, for repairs. Pressure checks with adjustments may
be accomplished in accordance with instructions given in this
chapter.
