CLOSE IMMEDIATELY [ ] Brakes [MEMORY] ............. APPLY FIRMLY — STOP ON REMAINING RUNWAY [ ] Mixture [MEMORY] ....................................... IDLE CUT-OFF [ ] Ignition [MEMORY] ............................................... OFF [ ] Fuel selector [MEMORY] .......................................... OFF [ ] Master switch [MEMORY] .......................................... OFF [ ] Evacuate aircraft if fire or fuel spill present ......... AS REQUIRED ENGINE FAILURE AFTER LIFT-OFF [EMERGENCY] ------------------------------------------ [ ] Best glide airspeed — pitch immediately to conserve altitude and extend glide range [MEMORY] ... ESTABLISH PER POH [ ] Landing area — select best available surface straight ahead or with the smallest practical turn; avoid low turns to return to runway [MEMORY] ... SELECTED [ ] Throttle [MEMORY] ............................................. CLOSE [ ] Flaps — adjust for selected landing surface; partial flap may allow steeper descent to a short field [MEMORY] ... AS REQUIRED FOR TERRAIN [ ] Mixture [MEMORY] ...................... IDLE CUT-OFF BEFORE TOUCHDOWN [ ] Ignition [MEMORY] .............................. OFF BEFORE TOUCHDOWN [ ] Master switch [MEMORY] ......................... OFF BEFORE TOUCHDOWN ENGINE FAILURE IN FLIGHT [EMERGENCY] ------------------------------------- [ ] Best glide airspeed — establish immediately to maximize range and time available [MEMORY] ... ESTABLISH PER POH [ ] Landing area — identify best available field or surface within glide range [MEMORY] ... SELECTED [ ] Carburetor heat [MEMORY] ... ON — apply immediately; carb ice may have caused the failure [ ] Fuel selector — switch to the tank with more fuel; verify selector is on a tank [MEMORY] ... FULLEST TANK [ ] Mixture [MEMORY] ............................................... RICH [ ] Throttle [MEMORY] ..... ADVANCE — check if partial power is available [ ] Primer — ensure closed and locked; an unlocked primer can lean the mixture ... IN AND LOCKED [ ] Ignition — cycle through LEFT and RIGHT to identify a failed magneto or broken lead ... CHECK BOTH [ ] Restart attempt — if engine fails to start and forced landing is committed, execute forced landing checklist ... ATTEMPT OR COMMIT TO FORCED LANDING [ ] Mayday call — declare emergency with position, altitude, and intentions ... 121.5 MHZ OR LAST ATC FREQUENCY ENGINE FIRE IN FLIGHT [EMERGENCY] ---------------------------------- [ ] Mixture [MEMORY] ... IDLE CUT-OFF — starve the engine of fuel immediately [ ] Fuel selector [MEMORY] .......................................... OFF [ ] Throttle [MEMORY] ... FULL OPEN — draw fuel remaining in the induction system away from the fire [ ] Ignition [MEMORY] ............................................... OFF [ ] Master switch [MEMORY] .......................................... OFF [ ] Heater and vents — close all fresh-air vents and cabin heat to reduce airflow feeding the fire [MEMORY] ... CLOSED [ ] Airspeed — increase to a speed that may help extinguish the fire by slipstream; do not exceed Vne [MEMORY] ... INCREASE WITHIN LIMITS [ ] Forced landing — execute forced landing procedure immediately; do not delay for a restart [MEMORY] ... INITIATE FORCED LANDING ENGINE FIRE ON GROUND (DURING OR AFTER START) [EMERGENCY] ---------------------------------------------------------- [ ] Starter — continue cranking if fire is in the induction system; cranking may draw fire back through the intake [MEMORY] ... CONTINUE CRANKING (induction fire) [ ] Throttle — advance to assist drawing fuel and fire into the engine if induction fire [MEMORY] ... ADVANCE (induction fire only) [ ] Mixture [MEMORY] ....................................... IDLE CUT-OFF [ ] Fuel selector [MEMORY] .......................................... OFF [ ] Ignition [MEMORY] ............................................... OFF [ ] Master switch [MEMORY] .......................................... OFF [ ] Evacuate — exit all occupants immediately; move upwind away from the aircraft [MEMORY] ... EVACUATE IMMEDIATELY [ ] Fire extinguisher — use only if fire is small, accessible, and escape route is clear ... AS ABLE; CALL FIRE SERVICES ELECTRICAL FIRE / SMOKE IN COCKPIT [EMERGENCY] ----------------------------------------------- [ ] Master switch [MEMORY] ............ OFF — remove all electrical power [ ] Avionics master switch [MEMORY] ................................. OFF [ ] All electrical switches — lights, fan, pitot heat [MEMORY] ...... OFF [ ] Vents — open to vent smoke from cockpit; fresh air assists in clearing fumes [MEMORY] ... OPEN VENTS, CLOSE HEAT [ ] Fire extinguisher — discharge toward source of smoke if identified and accessible ... AS REQUIRED [ ] Land as soon as practicable — smoke or fumes indicate a potential for rapid fire spread; do not delay [MEMORY] ... DIVERT AND LAND [ ] Electrical switches — after smoke clears, restore individual switches one at a time to identify the faulty circuit before landing ... RESTORE SELECTIVELY AS NEEDED [ ] Circuit breakers — do not reset a tripped breaker in flight unless essential for safety; a tripped breaker indicates a fault ... DO NOT RESET UNLESS ESSENTIAL LOSS OF OIL PRESSURE [EMERGENCY] --------------------------------- [ ] Oil pressure gauge — verify indication; cross-check oil temperature for confirming trend [MEMORY] ... VERIFY; CROSS-CHECK OIL TEMP [ ] Throttle — reduce power to minimum needed to maintain flight; lower power reduces engine stress [MEMORY] ... REDUCE TO MINIMUM REQUIRED [ ] Landing area — identify a suitable field or airport within close range; engine seizure may be imminent [MEMORY] ... IDENTIFY NEAREST SUITABLE AREA [ ] Mayday call — declare emergency with position, nature of malfunction, and intentions ... DECLARE EMERGENCY [ ] Land as soon as possible — if pressure is zero or temperature is rising abnormally, do not delay; engine seizure can occur without warning [MEMORY] ... LAND IMMEDIATELY [ ] After landing — do not run the engine; inspect for oil loss before any further operation ... SHUT DOWN AND INSPECT CARBURETOR ICE [ABNORMAL] -------------------------- [ ] Carburetor heat — apply FULL ON at first sign of unexplained RPM loss or engine roughness in cruise or descent [MEMORY] ... FULL ON [ ] RPM — monitor for initial further drop as ice melts and passes through the induction system, followed by recovery ... EXPECT BRIEF DROP THEN RECOVERY [ ] Throttle — avoid large changes while carburetor heat is applied; heat reduces available power ... STABLE THROTTLE [ ] Carburetor heat — leave ON until RPM recovers and stabilizes above original indication; then return to COLD ... LEAVE ON UNTIL RECOVERED; THEN COLD [ ] If RPM does not recover — land as soon as practicable; severe ice accumulation may not fully clear with heat alone [MEMORY] ... DIVERT IF NO RECOVERY [ ] Icing conditions — if conditions are conducive to carburetor ice (temperature between approximately 20 and 70 F with visible moisture or high humidity), apply carburetor heat periodically as a preventive measure ... APPLY PERIODICALLY IN ICING CONDITIONS FORCED LANDING (POWER-OFF) [EMERGENCY] --------------------------------------- [ ] Best glide airspeed — establish and maintain throughout the approach; do not let speed decay or build excessively [MEMORY] ... ESTABLISH AND MAINTAIN PER POH [ ] Landing area — select field considering length, surface, slope, obstacles, and wind direction; commit early [MEMORY] ... SELECTED AND COMMITTED [ ] Mayday call — transmit position, altitude, nature of emergency, and intended landing area ... 121.5 MHZ OR LAST ATC FREQUENCY [ ] Transponder .................................................... 7700 [ ] Fuel selector [MEMORY] .......................................... OFF [ ] Mixture [MEMORY] ....................................... IDLE CUT-OFF [ ] Ignition [MEMORY] ................ OFF at short final, prior to flare [ ] Master switch [MEMORY] ........... OFF at short final, prior to flare [ ] Seat belts and shoulder harnesses [MEMORY] ... CONFIRM TIGHT ON ALL OCCUPANTS [ ] Doors — unlatch before touchdown to prevent jamming in impact; hold door slightly ajar [MEMORY] ... UNLATCHED BEFORE TOUCHDOWN [ ] Flaps — extend on final as needed to control descent angle and landing speed per POH ... AS REQUIRED FOR FIELD AND CONDITIONS [ ] After landing — evacuate aircraft promptly and move upwind to prevent injury from possible fire ... EVACUATE AND MOVE CLEAR
