OVERWEIGHT LANDING PROCEDURES
In the event it is necessary to land with weight exceeding 3200 Lbs. (1452 Kg.) (max. landing
weight) the following procedure is recommended in addition to normal APPROACH FOR LAND-
ING procedures:
Approach Airspeed
80 KIAS

Use a flatter approach angle than normal, with power as necessary until a smooth touchdown is
assured.
Expect landing distance over a 50 feet obstacle (Ref. SECTION V) to increase at least 600 ft.
Conduct Gear and Tire Servicing inspection as required (Ref. SECTION VIII).

If circuit breaker will not reset, the following procedures are required:
1.
Reduce electrical load, as required, to maintain essential systems.
2.
Continue flight and LAND, when PRACTICABLE, to correct malfunction.
NOTE:
The only source of electrical power is from the selected battery. Monitor battery
voltage (min. 18V) and switch to other battery when necessary.
ALTERNATOR OUTPUT LOW
(Alternator annunciator warning light flashing)
Reduce electrical load.
If annunciator light still flashes:
Alternator Field Switch

Battery endurance will depend upon battery condition and electrical load on battery. If one bat-
tery becomes depleted, switch to other battery.
