8.16 BATTERY SERVICE
The GA8-TC 320 must be tted with a “no maintenance” 12 volt, 29 Ampere Hour Concorde
Sealed Lead Acid Battery (P/N RG-35A).
The battery is located in a compartment under the pilot’s seat in the cockpit To gain access to
the battery, remove the seat, oor carpet and screws securing the battery box cover.
WARNING:
DO NOT PERFORM ANY MAINTENANCE ON THE ELECTRICAL SYSTEM IN
CONJUNCTION WITH MAINTENANCE ON THE FUEL SYSTEM. THE ESCAPE
OF FUEL FUMES UNDER THE FLOOR AND/OR IN THE AIRCRAFT MAY
CAUSE AN EXPLOSION.
As the name implies, the “no maintenance” battery requires no routine maintenance other than
to check its security occasionally and to clean the terminals if required.
8.17 FLYABLE STORAGE
Aircraft in non-operational storage, for a maximum of 30 days, are considered to be in yable
storage status. Every seventh day during these periods, the propeller should be rotated by hand
through ve revolutions. This action “limbers” the oil and prevents any accumulation of corrosion
on engine cylinder walls.
WARNING:
FOR MAXIMUM SAFETY, CHECK THAT BOTH MAGNETOS ARE OFF, THE
THROTTLE CLOSED, THE MIXTURE CONTROL IS IN THE ICO POSITION,
AND THE AIRCRAFT IS SECURED BEFORE ROTATING THE PROPELLER
BY HAND. DO NOT STAND WITHIN THE ARC OF THE PROPELLER BLADES
WHILE TURNING THE PROPELLER.
After 30 days, the aircraft should preferably be own for 30 minutes. As well as helping to avoid
engine problems, this also helps to reduce accumulations of water in the fuel system, tops up
the battery charge, and exercises the other aircraft systems. If it is not possible to y the aircraft
a ground run up should be made just long enough to produce an oil temperature within the lower
green arc range. Excessive ground run up should be avoided.
If the aircraft is to be out of service for long periods, refer to the GA8-TC 320 SERVICE MANUAL
for proper storage procedures.
