OFF [ ] Fuel selector ................................................... OFF ** CAUTION: Do not attempt a turn back to the runway at low altitude. If airborne with insufficient runway remaining, land ahead or on the best available surface within a narrow arc of the departure heading. [ ] Occupants — advise to brace for impact ............... BRACE POSITION ENGINE FAILURE IN FLIGHT [EMERGENCY] ------------------------------------- [ ] Airspeed — pitch for best glide without delay [MEMORY] ... BEST GLIDE SPEED PER POH [ ] Landing area — identify best available field or surface within glide range [MEMORY] ... SELECTED; COMMIT TO IT [ ] Fuel selector — switch to opposite tank ...... OPPOSITE TANK SELECTED [ ] Mixture ........................................................ RICH [ ] Ignition switch ................................... BOTH — confirm ON [ ] Electric fuel pump ............................................... ON [ ] Throttle — advance if restart is being attempted ... AS REQUIRED FOR RESTART ATTEMPT [ ] If restart fails — secure engine and follow Forced Landing checklist ... PROCEED TO FORCED LANDING ENGINE FIRE IN FLIGHT [EMERGENCY] ---------------------------------- [ ] Mixture [MEMORY] .................. IDLE CUTOFF — starve fire of fuel [ ] Fuel selector [MEMORY] .......................................... OFF [ ] Throttle [MEMORY] ... FULL OPEN — clear residual fuel from induction system [ ] Electric fuel pump .............................................. OFF [ ] Master switch ............... OFF — remove electrical ignition source [ ] Airspeed — increase if fire persists to attempt to blow out flames; do not exceed Vne ... INCREASE AS PRACTICABLE PER POH [ ] If fire extinguishes — execute immediate precautionary landing; do not attempt restart ... PRECAUTIONARY LANDING; NO RESTART [ ] If fire continues — execute forced landing with urgency; follow Forced Landing checklist ... FORCED LANDING — EXPEDITE ENGINE FIRE ON GROUND [EMERGENCY] ---------------------------------- [ ] Mixture [MEMORY] ........................................ IDLE CUTOFF [ ] Ignition switch [MEMORY] ........................................ OFF [ ] Fuel selector [MEMORY] .......................................... OFF [ ] Master switch ................................................... OFF [ ] Occupants — evacuate immediately via car-style doors; move upwind of the aircraft ... ALL OCCUPANTS CLEAR; UPWIND [ ] Fire extinguisher — direct at base of fire through cowl openings if accessible without risk ... APPLIED IF SAFE [ ] Emergency services — call 911 / ATC / airport fire ......... NOTIFIED ELECTRICAL FIRE / SMOKE IN COCKPIT [EMERGENCY] ----------------------------------------------- [ ] Master switch [MEMORY] ........... OFF — isolate all electrical power [ ] Avionics master switch [MEMORY] ................................. OFF [ ] Vents and fresh air — open to ventilate cabin; do not fan smouldering materials ... VENTILATED [ ] If smoke and fire subside — identify and isolate the faulty circuit before restoring power ... FAULTY CIRCUIT IDENTIFIED AND ISOLATED [ ] Essential avionics — restore selectively and one at a time; monitor for recurrence ... RESTORED AS NEEDED FOR SAFE FLIGHT [ ] Land as soon as practicable ...... DIVERT TO NEAREST SUITABLE AIRPORT LOSS OF OIL PRESSURE [EMERGENCY] --------------------------------- [ ] Oil pressure gauge — confirm reading and crosscheck oil temperature for trend [MEMORY] ... CONFIRMED LOW; OIL TEMP NOTED [ ] Power — reduce to minimum required to maintain safe flight [MEMORY] ... POWER REDUCED [ ] Land as soon as possible — do not operate with low or zero oil pressure; total engine failure may follow [MEMORY] ... DIVERT IMMEDIATELY TO NEAREST AIRPORT [ ] Suitable landing area — identify in case of sudden engine seizure ... LANDING AREA IN SIGHT [ ] ATC — declare emergency and advise intentions ... ATC NOTIFIED; INTENTIONS STATED [ ] If engine seizes — follow Engine Failure in Flight checklist ... FORCED LANDING PROCEDURES INDUCTION SYSTEM ICING (ALTERNATE AIR) [EMERGENCY] --------------------------------------------------- ** CAUTION: The IO-540 is fuel-injected — carburetor ice does not occur. However, impact icing of the primary air inlet is possible in visible moisture. The TB 20 is equipped with an alternate air source; activation bypasses the primary induction inlet. [ ] Symptoms — rough running, loss of power, or unusual RPM/MAP fluctuation in IMC or visible moisture ... NOTED [ ] Alternate air control — select ALTERNATE AIR (or ALT AIR OPEN per aircraft labelling) [MEMORY] ... ALTERNATE AIR SELECTED [ ] Engine performance — monitor for recovery; expect slight power reduction on alternate air ... POWER RESTORED OR STABILISED [ ] Altitude and routing — avoid continued flight in icing conditions if practical ... ALTITUDE OR ROUTE ADJUSTED [ ] If power does not recover — treat as engine emergency and prepare for precautionary landing ... PRECAUTIONARY LANDING INITIATED FORCED LANDING (POWER-OFF) [EMERGENCY] --------------------------------------- [ ] Airspeed — establish and maintain best glide [MEMORY] ... BEST GLIDE SPEED PER POH [ ] Landing area — select the best available surface; commit and do not change plan at low altitude [MEMORY] ... FIELD SELECTED [ ] Transponder ................................. 7700 — squawk emergency [ ] ATC — declare MAYDAY; state position, altitude, and intentions ... MAYDAY DECLARED; POSITION GIVEN [ ] Fuel selector ................................................... OFF [ ] Mixture ................................................. IDLE CUTOFF [ ] Ignition switch ................................................. OFF [ ] Master switch — leave on until final approach to retain flap and gear operation, then OFF ... OFF BEFORE TOUCHDOWN [ ] Flaps — extend on final approach per POH to reduce touchdown speed ... EXTENDED AS REQUIRED [ ] Landing gear — extend if landing on a prepared surface; leave retracted for off-field terrain landing per judgement ... DOWN FOR PAVED/FIRM SURFACE; CONSIDER RETRACTED FOR ROUGH TERRAIN [ ] Seat belts and shoulder harnesses — all occupants confirm tight ... TIGHT [ ] Doors — unlatch before touchdown to prevent jamming ....... UNLATCHED GEAR UNSAFE / GEAR WILL NOT INDICATE DOWN [EMERGENCY] ------------------------------------------------------ [ ] Gear handle — confirm in DOWN position ............... DOWN CONFIRMED [ ] Airspeed — confirm within gear operating speed range ... WITHIN Vlo PER POH [ ] Circuit breakers — check gear-related breakers for tripped condition ... BREAKERS CHECKED; RESET IF TRIPPED ONCE [ ] Gear handle — recycle: raise then lower again ... RECYCLED; INDICATORS CHECKED [ ] If still unsafe — fly-by or request tower visual inspection if available ... VISUAL CONFIRMATION SOUGHT [ ] If gear will not extend normally — proceed to Emergency Gear Extension checklist ... EMERGENCY EXTENSION INITIATED EMERGENCY GEAR EXTENSION [EMERGENCY] ------------------------------------- ** CAUTION: Locate and review the manual gear extension mechanism in the specific aircraft before flight. Mechanism location and procedure vary by aircraft serial and modification status — always verify against the aircraft POH. [ ] Airspeed — reduce to below maximum gear extension speed and maintain [MEMORY] ... AT OR BELOW Vlo PER POH [ ] Landing gear handle ............................................ DOWN [ ] Gear circuit breaker — check and reset if tripped ... CHECKED; RESET IF APPROPRIATE [ ] Emergency gear extension — engage manual override per aircraft POH procedure ... OVERRIDE ENGAGED PER POH [ ] Gear position indicators — verify three green after manual extension ... THREE GREEN CONFIRMED — OR NOTE ANY UNSAFE INDICATION [ ] If any gear does not show green — do not retract; plan for minimum runway landing; notify ATC ... ATC ADVISED; EMERGENCY DECLARED IF NOT ALREADY [ ] After landing — do not taxi; shutdown on runway and await maintenance inspection before any further movement ...
