Stuck Pedal (Right) – Rotorcraft Flight Manual

Definitions

A right stuck pedal is a condition where too much nose-right thrust is being produced by the tail rotor, causing uncontrollable rightward yaw.

Recognize the signs of a right stuck pedal and understand the recovery procedure.

A stuck right pedal is most likely to be recognized at the end of a normal approach when applying power to stop the descent
As power is applied, an uncommanded right yaw will develop (cannot be corrected with left pedal)

Procedure 1–zero airspeed to a hover auto
- Initiate a go-around, maintaining your airspeed and altitude (eg, 60 KIAS and 300′ AGL)
- re-enter the pattern and set up another approach to the runway
- Lower the collective to establish a normal descent (the nose will move left when reducing power)
- Plan to arrive at a hover with zero airspeed
- If the procedure isn’t working out as planned, initiate a go-around before losing too much altitude and airspeed
- At the end of the descent, raise the collective to reduce the sink rate and align the nose with the ground track
- When in hover altitude with zero airspeed and the nose aligned with the runway centerline, land using a hover auto
Procedure 2–flare to powered landing
- Initiate a go-around, maintaining airspeed and gaining altitude (eg, 60 KIAs and up to 1000′ AGL); application of power will cause right-ward yaw
- Set up for a steep approach with approach airspeed (eg, 60 KIAS)
- Lower the collective until the nose is yawed to the left
- Continue the approach while maintaining airspeed
- At the bottom of the approach, flare to reduce airspeed and rate of descent; lower the collective as needed to prevent ballooning
- As the aircraft is decelerated, level the aircraft and raise the collective to align the nose with the ground track
- Close the throttle as needed to maintain alignment with the ground track and complete the landing
