EMERGENCY PROCEDURES
FORCED LANDINGS
If all attempts to restart the engine fail and a forced landing is imminent,
select a suitable field and prepare for the landing as discussed under
the Emergency Landing Without Engine Power checklist. Transmit
Mayday message on 121.5 MHz giving location, intentions and squawk
7700.
Before attempting an off airport landing with engine power available,
one should fly over the landing area at a safe, but low altitude, to
inspect the terrain for obstructions and surface conditions, proceeding
as discussed in the Precautionary Landing With Engine Power
checklist.
Prepare for ditching by securing or jettisoning heavy objects located in
the baggage area and collect folded coats for protection of occupants'
face at touchdown. Transmit Mayday messages on 121.5 MHz giving
location, intentions and squawk 7700. Avoid a landing flare because of
the difficulty in judging height over a water surface. The checklist
assumes the availability of power to make a precautionary water
landing. If power is not available, use of the airspeeds noted with
minimum flap extension will provide a more favorable attitude for a
power off ditching.
In a forced landing situation, do not turn off the MASTER switch,
AVIONICS switch or STBY BATT switch until a landing is assured.
Premature deactivation of the switches will disable all airplane electrical
systems.
