Cessna 172 SP — Emergency Procedures NOT FOR FLIGHT — source fidelity: not_applicable | operational review: none | completeness: partial | 2 unresolved safety defect(s) Source: authored — no source document Rights: original_expression CC-BY-4.0 Checklist hash: acad6d28427f3cfaa3c2825a0cda41117d0b747fd7185de5150c908f71b289fc Verify against the aircraft's own approved documentation before use. ======================================================================== ENGINE FAILURE ON TAKEOFF ROLL (BEFORE LIFT-OFF) [EMERGENCY] ------------------------------------------------------------- [ ] Throttle [MEMORY] ................................. CLOSE IMMEDIATELY [ ] Brakes [MEMORY] ............. APPLY FIRMLY — STOP ON REMAINING RUNWAY [ ] Mixture [MEMORY] ....................................... IDLE CUT-OFF [ ] Ignition [MEMORY] ............................................... OFF [ ] Master switch [MEMORY] .......................................... OFF [ ] Fuel selector [MEMORY] .......................................... OFF ENGINE FAILURE AFTER LIFTOFF [EMERGENCY] ----------------------------------------- [ ] Best glide airspeed — pitch immediately [MEMORY] ... ESTABLISH PER POH [ ] Landing area — land straight ahead or with minimal turn onto best available surface [MEMORY] ... SELECTED [ ] Throttle [MEMORY] ............................................. CLOSE [ ] Flaps — retract to reduce drag if altitude permits a controlled approach ahead [MEMORY] ... AS REQUIRED [ ] Mixture [MEMORY] ...................... IDLE CUT-OFF BEFORE TOUCHDOWN [ ] Ignition [MEMORY] .............................. OFF BEFORE TOUCHDOWN [ ] Master switch [MEMORY] ......................... OFF BEFORE TOUCHDOWN [ ] Fuel selector [MEMORY] ......................... OFF BEFORE TOUCHDOWN ** NOTE: Do not attempt to return to the runway unless altitude and glide performance clearly permit. A straight-ahead or shallow-turn landing is nearly always the safer choice. ENGINE FAILURE IN FLIGHT [EMERGENCY] ------------------------------------- [ ] Best glide airspeed — pitch for it immediately [MEMORY] ... ESTABLISHED PER POH [ ] Landing area — identify most suitable field or surface within glide range [MEMORY] ... IDENTIFIED [ ] Fuel selector — confirm not accidentally moved to OFF [MEMORY] ... BOTH [ ] Mixture [MEMORY] ............................................... RICH [ ] Throttle — advance to full; check for partial power recovery [MEMORY] ... FULL; MONITOR RESPONSE [ ] Ignition — cycle through LEFT and RIGHT individually to check for magneto failure [MEMORY] ... BOTH; CYCLE IF NO RESPONSE [ ] Fuel quantity — verify remaining on both gauges; rule out fuel exhaustion ... CONFIRMED FUEL REMAINING [ ] Restart attempt — if probable cause identified, correct and retry before committing to forced landing ... ATTEMPTED IF FEASIBLE [ ] Squawk 7700 and declare emergency — transmit position, nature, and souls on board on 121.5 MHz or current frequency ... DECLARED [ ] Passenger briefing — brace position and emergency exit procedure ... BRIEFED [ ] If engine does not restart — execute forced landing procedure ... PROCEED TO FORCED LANDING ENGINE FIRE IN FLIGHT [EMERGENCY] ---------------------------------- [ ] Mixture [MEMORY] ...... IDLE CUT-OFF — cut fuel to engine immediately [ ] Fuel selector [MEMORY] .......................................... OFF [ ] Throttle [MEMORY] ............................................. CLOSE [ ] Master and alternator switches [MEMORY] ......................... OFF [ ] Cabin heat and air vents — close all cockpit airflow paths to deny fire fresh air into cabin [MEMORY] ... CLOSED [ ] Airspeed — increase toward maneuvering speed if fire persists; airflow may extinguish fire ... INCREASED IF FIRE PERSISTS [ ] Declare emergency and proceed to nearest suitable landing area without delay ... MAYDAY DECLARED; LANDING AREA SELECTED [ ] Seat belts — all occupants secured and braced ................ SECURE ENGINE FIRE ON GROUND [EMERGENCY] ---------------------------------- [ ] Throttle — advance briefly to attempt to draw fire back through induction, then close [MEMORY] ... ADVANCED BRIEFLY THEN CLOSED [ ] Mixture [MEMORY] ....................................... IDLE CUT-OFF [ ] Fuel selector [MEMORY] .......................................... OFF [ ] Ignition [MEMORY] ............................................... OFF [ ] Master switch [MEMORY] .......................................... OFF [ ] Evacuate — all occupants exit immediately and move upwind to safe distance [MEMORY] ... EVACUATED UPWIND [ ] Fire extinguisher — use on engine if accessible and fire is not endangering personnel ... USED IF SAFE TO DO SO [ ] Emergency services — call fire/rescue; do not re-enter aircraft if fire persists ... CALLED ELECTRICAL FIRE / SMOKE IN COCKPIT [EMERGENCY] ----------------------------------------------- [ ] Master switch [MEMORY] .............. OFF — remove all power from bus [ ] All electrical switches [MEMORY] ... OFF — cycle all off before any power restoration [ ] Vents — open fresh-air vents to ventilate cockpit and clear smoke [MEMORY] ... OPEN [ ] Fire extinguisher — use if source is visible and accessible; aim at base of flame ... USED AS NEEDED [ ] Master switch — if flight requires electrical power, restore; turn equipment on one item at a time, watching for recurrence ... RESTORED SELECTIVELY IF ESSENTIAL [ ] Avionics master — leave OFF unless essential for navigation or ATC communication ... OFF UNLESS ESSENTIAL [ ] Land as soon as practicable — declare emergency; do not continue flight with unresolved electrical fire or smoke ... LANDING INITIATED LOSS OF OIL PRESSURE [EMERGENCY] --------------------------------- [ ] Oil pressure gauge — confirm reading; cross-check oil temperature for simultaneous rise indicating real oil loss vs. gauge failure [MEMORY] ... CONFIRMED LOW [ ] Throttle — reduce power to minimum required for continued flight [MEMORY] ... REDUCED [ ] Nearest suitable landing area — identify and proceed toward it without delay [MEMORY] ... IDENTIFIED AND PROCEEDING [ ] Treat engine as potentially seconds from seizure if pressure is zero and temperature is rising — do not delay landing [MEMORY] ... LANDING PRIORITY CONFIRMED [ ] ATC — advise of situation; squawk 7700 ...................... ADVISED [ ] Forced landing — execute before engine failure if pressure cannot be restored; a controlled power-on landing is preferable to a power-off arrival ... EXECUTING IF NOT RESTORED FORCED LANDING (POWER-OFF) [EMERGENCY] --------------------------------------- [ ] Best glide airspeed — establish and maintain per POH [MEMORY] ... ESTABLISHED PER POH [ ] Landing area — select largest, smoothest surface available into the wind; avoid power lines, fences, ditches, and sloped terrain [MEMORY] ... SELECTED [ ] Squawk 7700 and declare Mayday — transmit aircraft type, position, nature of emergency, and souls on board on 121.5 MHz or current frequency ... DECLARED [ ] ELT — activate manually if time permits ................... ACTIVATED [ ] Passenger briefing — brace position, seat belts tight, door unlatched before touchdown ... BRIEFED [ ] Flaps — deploy incrementally when landing is assured; full flaps for shortest roll-out if obstacle clearance is not a factor ... SET AS REQUIRED [ ] Fuel selector [MEMORY] ........................... OFF ON SHORT FINAL [ ] Mixture [MEMORY] ........................ IDLE CUT-OFF ON SHORT FINAL [ ] Ignition [MEMORY] ......................... OFF JUST BEFORE TOUCHDOWN [ ] Master switch — OFF just before touchdown, unless ELT is transmitting via aircraft power [MEMORY] ... OFF [ ] Doors — unlatch prior to touchdown to prevent jamming in a deformed airframe [MEMORY] ... UNLATCHED [ ] Touchdown attitude — minimum airspeed, tail-low; absorb impact through landing gear rather than nose-first ... TAIL-LOW AT MINIMUM SPEED [ ] Post-landing — exit aircraft upwind; move well clear; activate ELT if not already transmitting ... EVACUATED UPWIND
