DRAIMNG FI'EL SYSTEM
The bulk of the fuel may be drained by opening the individual drain on each tank.
The remaining fuel may be drained tfuough the fuel strainer. Any individual tank may be
drained by closing the fuel selector valve and then draining the desired tank.
TIRE INFLATTON
For maximum service from the tires, keep them inflated to the proper pressures - 28-30
psi for the nose gear and 3540 psi for the main gear. All wheels and tires are balanced before
original installation,. and -the relationship. of tire, tube, and wheel should be maintained "upon
reinstallation. Unbalanced wheels can cause extreme vibration in the landing gear; therefore, in
the installation of new components, it may be necessary to rebalance the wheels with the tires
mounted. When checking tire pressure, examine the tires for wear, cuts, bruises, and slippage.
BATTERY SERVICE
Access to the l2-volt battery is through a removable panel in the floor of the .forward
bAggage compartment. The battery box has a plastic tube which is normally closed off with a
chp and which should be opened occasionally to drain off any accumulation of liquid. The
blttery should be checked for proper fluid level. DO NOT fill the battery above the baffle
plates. DO NOT fill the battery with acid - use water only. A hydrometer check will determine
the percent of charge in the battery.
If the battery is not up to charge, recharge starting at a 4 amp rate and finishing with a 2
amp rate. Quick charges are not recommended.
FACTS YOU SHOULD KNOI{
The Federal Aviation Administration (FAA) occasionally publishes Airworthiness
Directives (ADs) that apply to specific groups of aircraft. They are mandatory changes and are
to be complied with within a time limit set by the FAA. When an AD is issued, it is sent to the
latest registered owner of the affected aircraft and also to subscribers of the service. The owner
should periodically check with his Piper dealer or A & P mechanic to see whether he has the
latest issued AD against Ns aircraft.
Piper Aircraft Corporation takes a continuing interest in having the owner get the most
efficient use from his aircraft and keeping it in the best mechanical condition. Consequently,
Piper Aircraft from time to time issues Service Bulletins, Service Letters and Service Spares
Letters relating to the aircraft.
Service Bulletins are of special importance and should be complied with promptly,' These
are sent to the latest registered owners, distributors and dealers. Depending on the nature of the
bulletin, material and labor allowances are usually applicable.
