R22 overspeeds
A quick question to all you R22 gurus out there. I found out over the weekend that it is possible to overspeed an R22 if you inadvertantly switch off the governor while it's winding up to 104%.
Scenario - you've finished all the checks, and are rolling on the throttle from 75%, simultaneously switching on the governor with your left thumb. This is something you've done 5 times in the past 2 hours so it's not as if you've not done it before. Next thing you know both the engine and rotor RPM are off the scale. While your brain panics, the needles stay there for 3 - 4 seconds before you roll off the throttle again, then spend the next 5 seconds idly musing if it's ok to fly. After the idle musings, it's time to shut down and speak to an instructor, who decides the aircraft should stay where it is until it's been looked at.
How can this happen ? "Hamfisted" springs to mind but why if the governor is switched off why should the now mechanical machine decide to go into overdrive ? Answers on a blank cheque, please, to pay for the damage !
And - no prizes for guessing why I'm asking the question.
