@ Loose rivets:your knowledge about the ATR is amazing.can you pls provide more details ?!
Sadly not that amazing. Too long ago and an aging brain prohibits remembering the exact point in the fuel line, but I did 'prove' that if a fuel pipeline fatigued at a certain point, the signal to stop boosted fuel would not be generated. An unlikely scenario, but not impossible. My argument was, that it was bad airmanship to leave the pumps selected on, even if they were supposed to be powered down.
