An external power installation is accessible through a receptacle located
on the right side of the fuselage aft of the wing. An external battery can be

having to gain access to the airplane's battery.
7. 3 9 EMERGENCY LOCATOR TRANSMITTER
The Emergency Locator Transmitter (ELT), is located in the aft portion of
the fuselage just below the stabilator leading edge and is accessible through a
plate on the right side of the fuselage. This plate is attached with slotted-head
nylon screws for ease of removal; these screws may be readily removed with a
variety of common icems such as a dime, a key, a knife blade, etc. If there are
no tools available in an emergency the screw heads may be broken off by any
means.

A battery replacement date is marked on the transmitter. To comply with
FAA regulations, the battery must be replaced on or before this date. The
battery must also be replaced if the transmitter has been used in an emergency
situation or if the accumulated test time exceeds one hour, or if the unit has been
inadvertently activated for an undetennined time period.
