That's interesting about #1. I was to take it from Christchurch to Sydney on Christmas Day after an overnight. When we got to the airport the aircraft was solidly iced with no deicing gear available as its summer time.
When we started number #1 it ran for 2 minutes and shut down so we immediately thought spar valve not open. Never did get it to run on Christmas day but the next day when we came back there was no problems despite no maintenance whatsoever.
