Piper Cherokee Six - Fuel Tanks

PIPER CHEROKEE
SIX SERVICE
MANUAL
8-3. TROUBLESHOOTING. Troubles peculiar to the instruments and related areas of the
fuel system are listed in Section IX along with their probable causes and suggested remedies.
Electrical and mechanical troubles
of the system are found in Table
VIII-III at the back of
this section. When troubleshooting, check from the power supply to the items affected. If
no trouble is found by this method, the trouble probably exists inside individual pieces of
equipment; they may then
be removed from the airplane and
an identical unit or units,
tested and known
to be good, installed
in their place.
8-4. FUEL TANKS.
NOTE
Through
a model change all
future PA-32-300 aircraft,
Serial
Numbers
32-7940001
and up, will
have incorporated
the
same fuel system as the PA-32R-300.
8-5. INSPECTION AND REPAIR
OF FUEL TANKS (ALUMINUM). Fuel
tanks should be
completely drained before inspection.
(Refer to Draining Fuel System,
Section II.) Each
tank should be carefully inspected for signs of leaks as indicated by telltale stains. In the
event a fuel
leak is detected, the fuel tank must be
removed as explained in Paragraphs
8-7,
8-9 or 8-1 1, and repaired as follows:
a.
The main fuel tanks
on PA-32-260,
300 and PA-32R-300
aircraft should
be sloshed
in
accordance with instructions
provided
on each can of
Randolph Sloshing
Sealer 802,
(MIL-L-6047B),
Piper P/N 757
572. One gallon of
sealer is required
for each tank. When
sloshing,
the finger strainer, fuel sender unit,
sight gauge and drain valves must
be removed
before
proceeding. Seal all openings. After
sloshing, check for leaks using a water
and soap
solution
and apply
1.5 pounds of pressure.
b. If the tank being inspected has previously been sloshed, the interior of the tank
should be inspected
for signs of peeling or chipping
sealer. Particular attention should
be
given the area around the filler neck as a result of the metal nozzle of the gas filler hose
nicking the sealer.
This inspection can best be accomplished
using a mirror and inspection
light
through the filler neck. If peeling and/or
chipping has occurred and separated
material
is found, the
tank should be sloshed as
explained in Step a.
c. After sloshing, reinspect
as outlined in Step b at intervals
of 100 hours.
NOTE
The fuel tank
should be replaced if it
has been damaged to
the extent it
cannot be repaired by
above procedures.
NOTE
When reinstalling drain valves, apply Parker Hannifin thread
lube, Piper code no. 913 224, to the male pipe threads. Do
not allow lubricant to enter fuel system.
