WFD post 358. I would go the engine shutdown and fire checklist from memory items close cowl flaps while on the way to land empty in about a 3 seconds pattern as it is an out of heavy maintenance test flight with nil pax/weight....... Is this answer ok, but Im not an Australian top gun so might be a bit simple.
OH I would have run the engines up with the LAME looking from the outside shutdown checked for leaks restarted etc before he jumped aboard rather than " started the left engine once the LAME was onboard per report ".
