AS350 B3E Emergency Procedures

A gong is generated each time a red warning appears on the warning panel

• When NR is below 360 RPM.
• When Max takeoff limits are exceeded.
• - procedure:
• 1.reduce collective pitch to maintain NR in the green arc or within power limits.
• 2. check engine parameters.

• When the NR is above 410 RPM
•  - procedure
• 1. Increase collective pitch to maintain NR in green arc.

• 1. Reduce collective pitch to maintain NR in the green arc.
• 2. Set IAS to VY (65 kts)
• 3. Twist grip to idle
• 4. Maneuver aircraft into wind
• 5. At 70' AGL flare
• 6. AT 20-25' and at constant attitude:
• 7. Gradually increase collective to reduce rate of descent and forward airspeed
• 8. Cyclic forward to adopt a slightly forward attitude (less than 10 degrees nose up)
• 9. Adjust pedals for slideslip
• 10. Increase collective to cushion touchdown
• 11. Once on the ground and stopped adjust collective pitch to full down.
• 12. Apply rotor brake below 170 RMP

• 1. Maintain Collective
• 2. Use pedals to control Yaw
• 3. Increase collective to cushion touch down

First sign is yaw to the left!!!

• 1. Throttle to idle
• 2. Increase collective to cushion touch down.

First sign is yaw to the left!!!

• 1. Cyclic - adjust to set IAS to VY and control yaw
• 2. Adjust collective to reduce sideslip
• 3. Land as soon as possible
• 4. On approach to landing:
• 5. Twist grip to idle position
• 6. Carry out autorotative landing

• You will notice nose coming to the right when you lower power like coming in to land from cruise flight. Low power setting, fixed left pedal...
• 1. Reduce airspeed to 70 kts
• 2. press Hyd button 3-5 seconds
• 3. Shallow, faster approach (50 kts when 300' or less).
• 4. perform running landing

• Nose will yaw to the right when adjusting power after takeoff. High power - fixed right pedal. (After takeoff)
• 1. Perform steeper than normal, slower approach.

• 1. Turn heating, demisting off.

• 9. When smoke clears:
• All electric consumers off
• 10. Emer switch on
• 11. Dct/Bat - on check DC parameters
• 12. Bat/Epu - On check DC parameters
• 13. Gene - on check dc parameters
• If DC parameters are not correct:
• 12. Gene - off
• 13. Unneccesary equipment off
• land as soon as practical
• If DC parameters are correct:
• 12. Avionic - On
• 13. All consumers - On, one by one to indentify the failed system: then keep off.

Note: when emer sw is actuated or battery and generator are offline, the VEMD goes off and only the analog NR indication remains on. Apply procedure for failure of both screens

• 1. Off1 or Off2
• 2. Read all available information on the other screen
• 3. Information is available using the scroll button on the VEMD or collective
• 4. If top VEMD fails 3-parameters engine page will be on bottom screen

• To avoid any power over limit, the maximum authorized power will be the power needed to establish level flight with the following law:
•  
• IAS - 100 kt at 0 Hp (-2 kt/1000')

Land as soon as practical

Carry out a no hover landing
