Sorry guys, nothing to do with the above accident, but in reply to sprocket..
I am pretty sure doing an in flight relight is part of the normal endorsment proceedures. Both of the single engine Turbine endo's I have done, a complete shutdown and relight has been done. Was an item to be ticked on the endorsment form(CASA).. As it is something that cannot really be simulated, like a piston engine. However was done at height (8000-10,000ft) and above an airstrip suitable for a forced landing. From 8500ft, had plenty of time to secure the engine, talk about the relight proceedures, wait for cooling if necessary then giving it a go. It does help as I have had to do an actual air start.
I am not sure what the rules and regs are about shutting down a single engine turbine in flight. Maybe someone could elaborate.. Knowing our trusty Aussie regs, it would say NO!!!!, followed by 12 pages of exemptions! for example, would be permitted if....
para 1- The Pilot is cool
para 2- Only on cloudy days 7/8ths or more
para 3- If the pilot wants to (see para 1)
para 4- If nobody is watching
etc... etc....
Anyways, sounds like the pilot/pilots involved did a bloody good job to get the a/c down safely..
