I’ve been involved in an incident in a Garrett powered aeroplane doing base training with an engine out.
The training captain used to supervise the trainee to pull the stop and feather above acceleration altitude and actually shut the thing down as part of the initial endorsement process in the aeroplane.
The trainees would do all the required single engine work and then relight the engine and land with all engines operative.
On this occasion the NTS system had failed, despite testing serviceable on the ground, when the start button on the engine was pressed for relight as per the QRH relight procedure in flight, the mighty Garrett spoiled up, the prop rapidly disced up and ran out of rudder in about ten seconds . She almost ended up on her back and would have ended up in a SSS.
The stop and feather was pulled with quick haste and a single engine landing conducted.
Simulators are very good for this type of thing.
