Emergency Checklist R22 BII - Heli Academy V1.0 2025-09

AIR RESTART PROCEDURE CAUTION: Do not attempt restart if engine malfunction is suspected or before safe autorotation is established. ACTION 1. Mixture - full rich. 2. Primer (if installed) - down and locked. 3. Throttle - closed, then cracked slightly. 4. Actuate starter with left hand. LOW RPM LOW RPM NOISE & VIBRATION OIL PRESSURE ENG RPM OIL P LIGHT ALT LIGHT YAW Information only! Always refer to POH, AFM, RFM! PROBLEM LOSS OF TAIL ROTOR THRUST IN FORWARD FLIGHT Mechanical error, bird or object strike, material fatigue. INDICATION Failure is usually indicated by nose right yaw which cannot be corrected by applying left pedal. ACTION 1. Immediately enter autorotation. 2. Maintain at least 70 KIAS if practical. 3. Select landing site, roll throttle off into overtravel spring, and perform autorotation landing. Note: When a suitable landing site is not available, the vertical stabilizers may permit limited controlled flight at low power settings and airspeeds above 70 KIAS; however, prior to reducing airspeed, enter full autorotation. PROBLEM LOSS OF TAIL ROTOR THRUST IN HOVER Mechanical error, bird or object strike, material fatigue. INDICATION Failure is usually indicated by nose right yaw which cannot be corrected by applying left pedal. ACTION 1. Immediately roll throttle off into overtravel spring and allow aircraft to settle. 2. Raise collective just before touchdown to cushion landing. PROBLEM HEADSET AUDIO FAILURE ACTION If headset audio fails, land as soon as practical. Note: For aircraft which provide low RPM horn through the audio system, pilot will not hear horn with a failed headset.

PROBLEM ENGINE FIRE DURING START ON GROUND INDICATION • Visible Fire • Smell of smoke • Visible Smoke • Abnormal Indications ACTION 1. Cranking – Continue and attempt to start which would suck flames and excess fuel into engine. 2. If engine starts, run at 50-60% RPM for a short time. 3. Fuel mixture – OFF. 4. Fuel valve – OFF. 5. Battery switch – OFF. 6. If time permits, apply rotor brake to stop rotors. 7. Exit helicopter. PROBLEM ENGINE FIRE IN FLIGHT INDICATION • Visible Fire • Smell of smoke • Visible Smoke • Abnormal Indications ACTION 1. Enter autorotation. 2. Cabin heat – OFF (if installed and time permits). 3. Cabin vent – ON (if time permits). 4. Landing ▪ If engine is running, perform normal landing, then fuel mixture OFF and fuel valve OFF. ▪ If engine stops running, fuel valve OFF and complete autorotation landing. 5. Battery switch – OFF. 6. If time permits, apply rotor brake to stop rotors. 7. Exit helicopter. PROBLEM ELECTRICAL FIRE IN FLIGHT INDICATION • Visible Fire • Smell of smoke • Visible Smoke • Abnormal Indications ACTION 1. Battery and alternator switches – OFF. 2. Open cabin vents. 3. Land immediately. 4. Fuel mixture OFF and fuel valve OFF. 5. If time permits, apply rotor brake to stop rotors. 6. Exit helicopter. Caution: Low RPM warning system and governor are inoperative with battery and alternator switches both off. Emergency Checklist R22 BII – Heli Academy V1.0 2025-09 | SW Information only! Always refer to POH, AFM, RFM! PROBLEM TACHOMETER FAILURE INDICATION • No Tacho readout • Unusual indication ACTION If rotor or engine tach malfunctions in flight, use remaining tach to monitor RPM. If it is not clear which tach is malfunctioning or if both tachs malfunction, allow governor to control RPM and land as soon as practical. Note: Each tach, the governor, and the low RPM horn are on separate power circuits. A special circuit allows the battery to supply power to the tachs with the battery and alternator switches both off. PROBLEM GOVERNOR FAILURE INDICATION • High/Low RPM • Erratic throttle movement ACTION If engine RPM governor malfunctions, grip throttle firmly to override the governor, then switch governor off. Complete flight using manual throttle control. Note: Monitor governor operation during flight by keeping hand lightly on throttle twist grip. If twist grip rotation becomes erratic or stops altogether, governor may be malfunctioning. If twist grip rotates steadily open or closed, override promptly to prevent RPM excursion. The “GOV OFF” light does not indicate governor failure. It only indicates that the governor is switched off. PROBLEM TAIL ROTOR CONTOL PROB- LEM IN FLIGHT (STUCK PEDAL) Pedal blockage, mechanical failure INDICATION Left or right yaw which can’t be corrected by applying opposite pedal input. ACTION 1. Stabilize flight with appropriate power setting and speed (around 70 kts) 2. If possible, get safe distance to ground (ca. 1000 ft AGL) 3. Verify problem with different power settings 4. Verify minimum safe speed to control yaw with tail fin 5. Select suitable landing spot, if possible hard surface 6. Perform running landing ROTOR TACH FAIL ENGINE TACH FAIL DUAL TACH FAIL LOW, HIGH ERRATIC RPM TWIST GRIP ROTATION ERRATIC OR STOPPED YAW YAW Emergency Checklist R22 BII – Heli Academy V1.0 2025-09 | SW Information only!

PROBLEM TAIL ROTOR CONTOL PROB- LEM IN HOVER (STUCK PEDAL) Pedal blockage, mechanical failure INDICATION Left or right yaw which can’t be corrected by applying opposite pedal input. ACTION RIGHT YAW 1. Immediately roll throttle off into overtravel spring and allow aircraft to settle. 2. Raise collective just before touchdown to cushion landing. LEFT YAW 1. Counteract yaw by increasing torque (raise collective) 2. Settle the aircraft using inertia PROBLEM EMERGENCY WATER LANDING INDICATION Same as Power Failure in Flight. ACTION POWER OFF 1. Follow same procedures as for power failure over land until contacting water. If time permits, unlatch doors prior to water contact. 2. Apply lateral cyclic when aircraft contacts water to stop rotors. 3. Release seat belt and quickly clear aircraft when rotors stop. POWER ON 1. Descend to hover above water. 2. Unlatch doors. 3. Passenger exit aircraft. 4. Fly to safe distance from passenger to avoid possible injury by rotors. 5. Switch battery and alternator OFF. 6. Roll throttle off into overtravel spring. 7. Keep aircraft level and apply full collective as aircraft contacts water. 8. Apply lateral cyclic to stop rotors. 9. Release seat belt and quickly clear aircraft when rotors stop. YAW YAW Emergency Checklist R22 BII – Heli Academy V1.0 2025-09 | SW Information only! Always refer to POH, AFM, RFM! PROBLEM RIGHT ROLL IN LOW “G” CONDITION ACTION Gradually apply aft cyclic to restore positive “G” forces and main rotor thrust. Do not apply lateral cyclic until positive “G” forces have been established. PROBLEM UNCOMMANDED PITCH, ROLL OR YAW RESULTING FROM FLIGHT IN TURBULENCE. ACTION Gradually apply controls to maintain rotor RPM, positive “G” forces, and to eliminate sideslip. Minimize cyclic control inputs in turbulence; do not overcontrol. PROBLEM INADVERTENT ENCOUNTER WITH MODERATE, SEVERE, OR EXTREME TURBULENCE. ACTION If the area of turbulence is isolated, depart the area; otherwise, land the helicopter as soon as practical.
