Ignition switch — verify on BOTH; try LEFT then RIGHT if no restartBOTH (CHECK)
Starter — attempt restart if altitude and conditions permitATTEMPT PER POH RESTART PROCEDURE
If restart unsuccessful — declare emergency; select landing area; initiate forced landing procedureMAYDAY DECLARED, FORCED LANDING INITIATED
Squawk 7700 — if transponder accessible and time permits7700 SET

Cabin heat and ventsMEMORYCLOSE ALL (prevent smoke and fumes entering cockpit)
Airspeed — increase to accelerate descent and help extinguish fire; do not exceed VNEINCREASE PER POH GUIDANCE
Canopy — unlatch before touchdown; declare emergency; select landing areaUNLATCHED; FORCED LANDING INITIATED

Canopy — open and egress immediatelyMEMORYOPEN; EVACUATE AIRCRAFT
Fire extinguisher — use external extinguisher on fire if accessible without personal riskAPPLY IF SAFE TO DO SO
Emergency servicesNOTIFY IMMEDIATELY — CALL 911

Master switchMEMORYOFF
All electrical switches — radios, lights, avionicsMEMORYOFF
Cabin vents — open to clear smoke from cockpitMEMORYOPEN
Canopy — if smoke is heavy and flight conditions permit, crack canopy for ventilationAS REQUIRED FOR SMOKE REMOVAL
If fire is out and smoke clears — selectively restore electrical power one switch at a time to identify faultRESTORE SELECTIVELY; ISOLATE FAULT
Land — plan expedited landing at nearest suitable airport; declare emergency if warrantedLAND AS SOON AS PRACTICABLE

Oil pressure gauge — verify indication; cross-check with oil temperature for trendMEMORYLOW PRESSURE CONFIRMED
Throttle — reduce power immediately to decrease engine stressMEMORYREDUCE POWER
Landing area — identify nearest suitable airport or fieldMEMORYNEAREST AIRPORT IDENTIFIED
Squawk 7700 and declare emergency if engine failure imminent or oil temperature rising rapidlyMAYDAY IF REQUIRED
Engine instruments — monitor closely; be prepared for sudden engine roughness or seizureCONTINUOUS MONITORING
Land — do not delay; engine failure without lubrication is imminentLAND AS SOON AS POSSIBLE

Carburetor heat — apply full hot immediately; do not remove until RPM recovers and then stabilizesMEMORYFULL HOT — HOLD UNTIL CLEAR
Throttle — avoid closing during heat application; maintain sufficient power to sustain flightMAINTAIN SUFFICIENT POWER
RPM — expect a brief further drop as ice melts and water ingests through carburetor; then RPM should rise and stabilize above original indicationMONITOR FOR RECOVERY
If RPM does not recover — declare emergency; identify nearest landing area; initiate descentEMERGENCY DECLARED IF NO RECOVERY
Carburetor heat — once ice is cleared, return to COLD for normal operations; continue to monitorCOLD WHEN CLEAR; MONITOR CONTINUOUSLY
Conditions — remain alert to icing conditions; apply carb heat preemptively in high-risk conditions per POH guidanceAPPLY PREVENTIVELY IN ICING CONDITIONS

Best glide airspeed — establish and maintainMEMORYESTABLISHED PER POH
Landing area — select best available surface; favor fields with consistent short grass; avoid wires, ditches, and slopesMEMORYSELECTED
Squawk 7700 and declare MAYDAY on 121.5 MHz or last used frequencyMAYDAY DECLARED, 7700 SET

Final approach — align with landing surface; plan for a controlled touchdown at minimum safe airspeed; flaps as appropriate per altitude and POHCONFIGURED FOR LANDING
