If all attempts to restart the engine fail and a forced landing is
imminent, select a suitable field and prepare for the landing as dis-
cussed in the checklist for engine-off emergency landings.
Before attempting an "off airport" landing with engine power avail-
able, one should drag the landing area at a safe but low altitude to
inspect the terrain for obstructions and surface conditions, proceeding
as discussed under the Precautionary Landing With Engine Power
checklist.
Prepare for ditching by securing or jettisoning heavy objects locat-
ed in the baggage area and collect folded coats for protection of occu-
pants' face at touchdown. Transmit Mayday message on 121.5 MHz
giving location and intentions.
Avoid a landing flare because of diffi-
culty in judging height over a water surface.
LA ND I N G W I T H OU T E LE V ATO R, C ONT R,O L
Trim for horizontal flight(with an airspeed of approximately 60 KIAS
and flaps set to 20") by using throttle and elevator trim control. Then do
not change the elevatoi trim control settingl control the glide angle by -
adjusting power exclusively.
At flareout, the nose-down moment resulting from power reduction is
an adverse factor and the airplane may hit on the nose wheel. Consequently,
at flareout, the elevator trim control should be adjusted toward the full
nose-up position and the power adjusted so that the airplane will rotate to
the horizontal attitude for touchdown. Close the throttle at touchdown.
FIRE S
Although engine fires are extremely rare in flight, the steps of the
appropriate checklist should be followed if one is encountered. After
completion of this procedure, execute a forced landing. Do not attempt
to restart the engine.
The initial indication of an electrical fire is usually the odor of burn-
ing insulation. The checklist for this problem should result in elimination
of the fire,
