# Grumman AA-5B Tiger — Emergency Procedures

> **NOT FOR FLIGHT** — source fidelity: not_applicable | operational review: none | completeness: partial | 2 unresolved safety defect(s)

Emergency procedures for the Grumman AA-5B Tiger with Lycoming O-360 carbureted engine. Memory items are marked accordingly. Contains no numeric limitations; all airspeeds must come from the specific aircraft POH. This is an aide-memoire only — aviate first, then navigate and communicate. The O-360 is carbureted; carburetor icing is applicable and included.

> **safety_defect**: Contains no airspeeds, power settings, or other numeric limits — must come from aircraft POH.
> **safety_defect**: Emergency checklists must be studied, practiced, and memorized. This file is an aide-memoire only. Aviate first, then navigate and communicate.
> **content_gap**: Equipment variations across AA-5B production affect available instruments and systems during emergencies. Verify procedures against the specific aircraft POH.

- [ ] Fuel selector `MEMORY` — **BOTH (or opposite tank if imbalanced)**
- [ ] Carburetor heat `MEMORY` — **FULL HOT**
- [ ] Throttle `MEMORY` — **ADVANCE TO DETERMINE IF ENGINE WILL RESPOND**
- [ ] Mixture — **RICH**
- [ ] Primer — **IN AND LOCKED**
- [ ] Ignition switch — verify on BOTH; try LEFT then RIGHT if no restart — **BOTH (CHECK)**
- [ ] Starter — attempt restart if altitude and conditions permit — **ATTEMPT PER POH RESTART PROCEDURE**
- [ ] If restart unsuccessful — declare emergency; select landing area; initiate forced landing procedure — **MAYDAY DECLARED, FORCED LANDING INITIATED**
- [ ] Squawk 7700 — if transponder accessible and time permits — **7700 SET**

## Engine Fire in Flight (EMERGENCY)

- [ ] Mixture `MEMORY` — **IDLE CUT-OFF**
- [ ] Fuel selector `MEMORY` — **OFF**
- [ ] Throttle `MEMORY` — **FULL OPEN (to exhaust remaining fuel in lines)**
- [ ] Ignition switch `MEMORY` — **OFF**
- [ ] Master switch `MEMORY` — **OFF**
- [ ] Cabin heat and vents `MEMORY` — **CLOSE ALL (prevent smoke and fumes entering cockpit)**
- [ ] Airspeed — increase to accelerate descent and help extinguish fire; do not exceed VNE — **INCREASE PER POH GUIDANCE**
- [ ] Canopy — unlatch before touchdown; declare emergency; select landing area — **UNLATCHED; FORCED LANDING INITIATED**

## Engine Fire on Ground (EMERGENCY)

- [ ] Throttle `MEMORY` — **FULL OPEN MOMENTARILY (to attempt to draw fire back into engine)**
- [ ] Mixture `MEMORY` — **IDLE CUT-OFF**
- [ ] Fuel selector `MEMORY` — **OFF**
- [ ] Ignition switch `MEMORY` — **OFF**
- [ ] Master switch `MEMORY` — **OFF**
- [ ] Canopy — open and egress immediately `MEMORY` — **OPEN; EVACUATE AIRCRAFT**
- [ ] Fire extinguisher — use external extinguisher on fire if accessible without personal risk — **APPLY IF SAFE TO DO SO**
- [ ] Emergency services — **NOTIFY IMMEDIATELY — CALL 911**

## Electrical Fire / Smoke in Cockpit (EMERGENCY)

- [ ] Master switch `MEMORY` — **OFF**
- [ ] All electrical switches — radios, lights, avionics `MEMORY` — **OFF**
- [ ] Cabin vents — open to clear smoke from cockpit `MEMORY` — **OPEN**
- [ ] Canopy — if smoke is heavy and flight conditions permit, crack canopy for ventilation — **AS REQUIRED FOR SMOKE REMOVAL**
- [ ] If fire is out and smoke clears — selectively restore electrical power one switch at a time to identify fault — **RESTORE SELECTIVELY; ISOLATE FAULT**
- [ ] Land — plan expedited landing at nearest suitable airport; declare emergency if warranted — **LAND AS SOON AS PRACTICABLE**

## Loss of Oil Pressure (EMERGENCY)

- [ ] Oil pressure gauge — verify indication; cross-check with oil temperature for trend `MEMORY` — **LOW PRESSURE CONFIRMED**
- [ ] Throttle — reduce power immediately to decrease engine stress `MEMORY` — **REDUCE POWER**
- [ ] Landing area — identify nearest suitable airport or field `MEMORY` — **NEAREST AIRPORT IDENTIFIED**
- [ ] Squawk 7700 and declare emergency if engine failure imminent or oil temperature rising rapidly — **MAYDAY IF REQUIRED**
- [ ] Engine instruments — monitor closely; be prepared for sudden engine roughness or seizure — **CONTINUOUS MONITORING**
- [ ] Land — do not delay; engine failure without lubrication is imminent — **LAND AS SOON AS POSSIBLE**

## Carburetor Ice (ABNORMAL)

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

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

- [ ] Best glide airspeed — establish and maintain `MEMORY` — **ESTABLISHED PER POH**
- [ ] Landing area — select best available surface; favor fields with consistent short grass; avoid wires, ditches, and slopes `MEMORY` — **SELECTED**
- [ ] Squawk 7700 and declare MAYDAY on 121.5 MHz or last used frequency — **MAYDAY DECLARED, 7700 SET**
- [ ] Fuel selector — **OFF**
- [ ] Mixture — **IDLE CUT-OFF**
- [ ] Ignition switch — **OFF (when landing is assured)**
- [ ] Master switch — **OFF (when landing is assured)**
- [ ] Canopy — unlatch before touchdown to ensure exit is possible after landing `MEMORY` — **UNLATCHED**
- [ ] Seat belts and shoulder harnesses — all occupants tightened `MEMORY` — **TIGHTENED AND LOCKED**
- [ ] Final approach — align with landing surface; plan for a controlled touchdown at minimum safe airspeed; flaps as appropriate per altitude and POH — **CONFIGURED FOR LANDING**
