Why is this thread only appearing now?!
Jeez,
Pilots: Don't you guys keep uptodate with Manufacture's POH updates. $10 a year is all you need as a pilot.
Owners / Operators, also bear in mind that if you are not changing the POH in your aircraft you are not airworthy! Read 91.9(b) and note the word 'current'
Students: Go an look in the POH (in aircraft that you next fly) and see if there are updates from Feb 23 2004. If not ask your instructor what's going on and refuse to fly!!! (Just stirring!)
For those instructors out there, who didn't know about these updates until now...what sort of role model behaviour is that for your students?
The 'Govenor On' change is part of the Feb 2004 updates, which includes a total of 50 pages! I suggest you go through your old POH carefully and compare them to a new one. Or better still, buy a new one then subscribe for updates.
Anyway, enough stirring.
According to a Robbie representative (I called to ask the same question), the govenor on is put there as they didn't see much of a drop in overspeed cases during initial pickup, cause people simply for got to switch it on. Read Safety Notice SN36.
NOTE also in the 'Shutdown Procedure' there is no 'govenor off'! For the same reason. Frank obviously wants us to keep it on continously.
As for practical implication of this...the warm up and mag checks is at 75% so there is no reason why not to have the govenor on. It kicks in at 80% as mentioned before. Same with shut down...no problem.
There are a whole load of other changes...which I was going to mention, but can't be bothered now.
GO GET THE UPDATES!
regards..
