Oh, Flyak, you just brought back an awful memory for me.
Similar situation, a rotten old Enstrom, jumping out of western Sydney, and the horrible aircraft would refuse to start after the lads re-packed their chutes between jumps, the engine was still too hot. Only got 2 jumps in that day, it was too long between flights so I got sent home. I was quite happy about this because I hated and detested being in the Enstrom, rattly cheap-looking thing that couldn't even hold height if the turbo got a bit tired. Ptui!
