# Piper PA-28-161 Warrior II — Emergency Procedures (independently worded)

> **NOT FOR FLIGHT** — source fidelity: not_applicable | operational review: none | completeness: partial | 1 unresolved safety defect(s)

Emergency procedures for the Piper PA-28-161 Warrior II with Lycoming O-320 engine. Memory items are marked. No airspeeds, power settings, fuel quantities, or other numerical limits are stated — those must come from the specific aircraft's POH. This file does not replace formal emergency training. Verify all procedures against the actual aircraft POH before flight.

> **safety_defect**: Contains no airspeeds, power settings, fuel quantities or other limitations — must come from aircraft POH.
> **content_gap**: Equipment variations exist across this model/variant. Verify items against the specific aircraft before use.

## Engine Failure After Lift-Off (EMERGENCY)

- [ ] Airspeed `MEMORY` — **BEST GLIDE — ESTABLISH IMMEDIATELY PER POH**
> **CAUTION:** Do not attempt to turn back to the runway at low altitude. Land approximately straight ahead or with small heading changes to avoid obstacles.
- [ ] Landing area — select best available surface ahead within the glide `MEMORY` — **SELECTED**
- [ ] Throttle `MEMORY` — **CLOSED**
- [ ] Mixture — **IDLE CUT-OFF when landing is assured**
- [ ] Ignition switch — **OFF when landing is assured**
- [ ] Master switch — **OFF before touchdown**

## Engine Failure in Flight (EMERGENCY)

- [ ] Airspeed `MEMORY` — **BEST GLIDE PER POH — ESTABLISH IMMEDIATELY**
- [ ] Landing area — identify best suitable field or airport within gliding range `MEMORY` — **SELECTED; PATTERN TO IT PLANNED**
- [ ] Fuel selector `MEMORY` — **BOTH — confirm handle fully seated in detent**
- [ ] Mixture `MEMORY` — **RICH**
- [ ] Carburetor heat `MEMORY` — **ON — apply to clear possible carburetor ice**
- [ ] Magnetos — cycle LEFT, then RIGHT, then BOTH `MEMORY` — **CHECK FOR DEAD MAGNETO; RETURN TO BOTH OR OPERATING POSITION**
- [ ] Primer — **CONFIRM IN AND LOCKED**
- [ ] Throttle — attempt restart if propeller is windmilling — **ADVANCE FROM IDLE; ATTEMPT RESTART**
- [ ] Transponder — **SQUAWK 7700**
- [ ] Mayday call — current frequency or 121.5 MHz — **POSITION, ALTITUDE, INTENTIONS TRANSMITTED**
- [ ] If restart not achieved, commit to forced landing — do not delay the transition to forced landing procedure

## Engine Fire in Flight (EMERGENCY)

- [ ] Mixture `MEMORY` — **IDLE CUT-OFF — cut fuel to engine immediately**
- [ ] Fuel selector `MEMORY` — **OFF**
- [ ] Throttle `MEMORY` — **FULL OPEN — help exhaust residual fuel from the system**
- [ ] Master switch `MEMORY` — **OFF — remove electrical ignition sources**
- [ ] Cabin heat and all air vents `MEMORY` — **CLOSE ALL — prevent fumes and smoke from entering cabin**
- [ ] Airspeed — increase as practical to aid in extinguishing flames — **INCREASED WITHIN STRUCTURAL LIMITS**
- [ ] Land immediately at the nearest suitable area — do not delay to troubleshoot

## Engine Fire on Ground (EMERGENCY)

- [ ] Throttle — advance briefly to full to draw flames back into the engine through the induction system `MEMORY` — **FULL MOMENTARILY**
- [ ] Mixture `MEMORY` — **IDLE CUT-OFF**
- [ ] Fuel selector `MEMORY` — **OFF**
- [ ] Magneto / ignition switch `MEMORY` — **OFF**
- [ ] Master switch `MEMORY` — **OFF**
- [ ] Evacuate the aircraft immediately; move well clear upwind
- [ ] Use fire extinguisher only if the fire can be safely attacked without entering the hazard zone

## Electrical Fire / Smoke in Cockpit (EMERGENCY)

- [ ] Master switch `MEMORY` — **OFF — remove electrical power from all circuits**
- [ ] Avionics master `MEMORY` — **OFF**
- [ ] All individual switches `MEMORY` — **OFF**
- [ ] Cabin vents `MEMORY` — **OPEN — ventilate to clear smoke from cockpit**
- [ ] If fire has subsided — master switch ON; restore switches one at a time to identify faulty circuit; leave faulty circuit OFF — **FAULTY CIRCUIT ISOLATED AND LEFT OFF**
- [ ] Transponder — squawk 7700 if avionics are restored — **7700**
- [ ] Land as soon as practicable — do not delay landing after any cockpit fire or smoke event

## Loss of Oil Pressure (EMERGENCY)

- [ ] Oil pressure indication `MEMORY` — **CONFIRM — distinguish gradual decline from sudden loss**
- [ ] Oil temperature `MEMORY` — **MONITOR — rising temperature with falling pressure confirms oil system distress**
- [ ] Power `MEMORY` — **REDUCE TO MINIMUM REQUIRED; PLAN IMMEDIATE LANDING**
- [ ] Landing area — identify nearest suitable airport or field; begin descending toward it — **SELECTED; DESCENDING**
- [ ] Mayday call — advise ATC of situation — **DECLARED ON CURRENT FREQUENCY OR 121.5 MHz**
> **CAUTION:** An engine with no oil pressure can seize without warning. Do not continue flight or delay landing.

## Carburetor Ice (ABNORMAL)

- [ ] Recognition — unexplained RPM loss, rough running, or power loss; particularly in visible moisture or suspect temperature range `MEMORY` — **SUSPECTED CARBURETOR ICE**
- [ ] Carburetor heat `MEMORY` — **FULL HOT — apply immediately; do not cycle on and off**
- [ ] Engine response — expect initial further RPM drop as ice melts; smooth return of RPM and power confirms ice was present — **MONITOR FOR RECOVERY**
- [ ] Carburetor heat — leave ON until icing conditions are exited and normal operation is confirmed — **REMAIN ON AS REQUIRED**
- [ ] If engine does not recover, declare emergency and initiate forced landing without delay

## Forced Landing (Power-Off) (EMERGENCY)

- [ ] Airspeed `MEMORY` — **BEST GLIDE PER POH — ESTABLISH AND MAINTAIN**
- [ ] Landing area — select largest available flat surface, preferably into wind; avoid terrain, wires, and populated areas `MEMORY` — **SELECTED**
- [ ] Mayday call — position, altitude, souls on board, intentions `MEMORY` — **TRANSMITTED ON CURRENT FREQUENCY OR 121.5 MHz**
- [ ] Transponder — **SQUAWK 7700**
- [ ] Approach — fly a recognizable pattern to the chosen field; preserve altitude margin; do not undershoot — **PATTERN TO SELECTED FIELD**
- [ ] Flaps — deploy as needed to manage touchdown point and energy — **AS REQUIRED FOR FIELD LENGTH**
- [ ] Fuel selector — OFF on short final — **OFF**
- [ ] Mixture — IDLE CUT-OFF on short final — **IDLE CUT-OFF**
- [ ] Magneto / ignition switch — OFF on short final — **OFF**
- [ ] Master switch — OFF on short final — **OFF**
- [ ] Doors — unlatch before touchdown to prevent jamming and ease evacuation — **UNLATCHED**
- [ ] Touch down at minimum sink rate; aim for far end of available landing area to maximize rollout distance
