Operator’s procedure to use mixture to simulate engine failure

Fly Oz's asymmetric training procedure involved failing one engine using the mixture control without confirmation the engine was subsequently restarted, rather than reducing throttle to simulate zero thrust in accordance with the Beechcraft E55 Airplane Flight Manual. This increased the risk of undetected asymmetric operation during descent and landing and the associated loss of control.

Fly Oz has amended its multi-engine training to simulate engine failures only using throttle (not mixture). Reducing throttle to simulate zero thrust in accordance with the Beechcraft E55 Airplane Flight Manual will reduce the risk of undetected asymmetric operation during descent and landing and the associated loss of control, which addresses the safety issue.
