If the engine quits immediately after takeoff, there will not be sufficient time
to attempt a restart; focus instead on flying the airplane and picking a landing
spot. The following steps need to be memorized and rehearsed. There will be no
time to refer to a checklist at low altitudes. Memorize the Engine Failure During
Takeoff Roll, Engine Failure Immediately After Takeoff and the Emergency
Landing No Engine Power checklists.
Emergency Landing No Engine Power
Immediately adjust from a nose-high takeoff pitch attitude by lowering the
pitch attitude sufficiently to maintain airspeed, and trim for best glide speed.
1. Landing Area.......................................................................Select and Inspect
2. Airspeed (trim).....................................................................................Best Glide
70 KIAS (flaps UP) or 65 KIAS (Flaps 10 to Full)
Steps needed to reduce the chance of fire are next. Always take steps to prevent
a fire when landing off-airport. The fuel tank may rupture and spill fuel during
the landing, and these steps will help reduce ignition sources.
3. Mixture........................................................................................................... Cutoff
This will cut off the fuel flow to the engine.
4. Fuel Shutoff.........................................................................................................Off
This step closes the fuel valve that is on the engine side of the firewall.
5. Magnetos Switch..............................................................................................Off
This step will help prevent the spark plugs from firing.
While performing these steps, simultaneously maneuver to the best possible
touchdown spot with the least amount of obstacles. Maintaining airspeed above
V SO is imperative. Avoid stalling the airplane before touchdown at all costs.
The next steps configure the aircraft for the forced landing.
6. Flaps (Full Recommended)..........................................................As Required
Deploying flaps allows the aircraft to touch down at the slowest
possible airspeed. Any obstacles or rough terrain will do less damage at
slower speeds. The stall warning should sound just before touchdown.
NOTE: It is critical to fight the tendency to pull back excessively on
the yoke to avoid hitting something. Any increase in the angle
of attack at this point will cause the airplane to stall. A stall prior
to touchdown will increase the vertical descent rate, and cause
much more damage to the airplane and occupants on board.
