Cessna 172 SP — Emergency Procedures

Engine Failure on Takeoff Roll (Before Lift-Off) Throttle CLOSE IMMEDIATELY Brakes APPLY FIRMLY — STOP ON REMAINING RUNWAY Mixture IDLE CUT-OFF Ignition OFF Master switch OFF Fuel selector OFF

Engine Failure After Liftoff Best glide airspeed — pitch immediately ESTABLISH PER POH Landing area — land straight ahead or with minimal turn onto best available surface SELECTED Throttle CLOSE Flaps — retract to reduce drag if altitude permits a controlled approach ahead AS REQUIRED Mixture IDLE CUT-OFF BEFORE TOUCHDOWN Ignition OFF BEFORE TOUCHDOWN Master switch OFF BEFORE TOUCHDOWN Fuel selector OFF BEFORE TOUCHDOWN 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 Best glide airspeed — pitch for it immediately ESTABLISHED PER POH Landing area — identify most suitable field or surface within glide range IDENTIFIED Fuel selector — confirm not accidentally moved to OFF BOTH Mixture RICH Throttle — advance to full; check for partial power recovery FULL; MONITOR RESPONSE Ignition — cycle through LEFT and RIGHT individually to check for magneto failure 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 Mixture IDLE CUT-OFF — cut fuel to engine immediately Fuel selector OFF Throttle CLOSE Master and alternator switches OFF Cabin heat and air vents — close all cockpit airflow paths to deny fire fresh air into cabin 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 Throttle — advance briefly to attempt to draw fire back through induction, then close ADVANCED BRIEFLY THEN CLOSED Mixture IDLE CUT-OFF Fuel selector OFF Ignition OFF Master switch OFF Evacuate — all occupants exit immediately and move upwind to safe distance 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 Master switch OFF — remove all power from bus All electrical switches OFF — cycle all off before any power restoration Vents — open fresh-air vents to ventilate cockpit and clear smoke 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 Oil pressure gauge — confirm reading; cross-check oil temperature for simultaneous rise indicating real oil loss vs. gauge failure CONFIRMED LOW Throttle — reduce power to minimum required for continued flight REDUCED Nearest suitable landing area — identify and proceed toward it without delay IDENTIFIED AND PROCEEDING Treat engine as potentially seconds from seizure if pressure is zero and temperature is rising — do not delay landing 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) Best glide airspeed — establish and maintain per POH ESTABLISHED PER POH Landing area — select largest, smoothest surface available into the wind; avoid power lines, fences, ditches, and sloped terrain 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 OFF ON SHORT FINAL Mixture IDLE CUT-OFF ON SHORT FINAL Ignition OFF JUST BEFORE TOUCHDOWN Master switch — OFF just before touchdown, unless ELT is transmitting via aircraft power OFF Doors — unlatch prior to touchdown to prevent jamming in a deformed airframe 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
