| Subject: | Re: MT P860-3 Prop Gov fail. |
In looking more closely at my recorder data on www.savvyanalysis.com,
there is something that stands out to me.
Prior to my PG failure, there were four monetary upward spikes in my RPM of approx
150RPM each. There were none on the previous segment of the flight, nor on
the previous flight.
The first one happened 17 minutes prior to the failure. They are just blips with
no duration at the peak. I honestly didn't notice them in the flight.
I am not expert on any of this stuff, and just started with the software, but,
If I were to be in a situation where I was going to fly with one of these PG's,
I would set my max RPM alert to 100 rpm higher than what I planned to use at
cruise. (I normally cruise at 2300 below 10K and 2400 above).
One could do it prior to flight and just deal with the alert on takeoff, or reset
the alert level once established in cruise. At any rate, it could give an
alert that something is potentially wrong and give more time to GYAOTG

One could set your governor to a max rpm of 2575, which is the redline
for the 250 hp rating used in the Aztec and Comanche 250. Or as you
suggest, put an alarm in at somewhere around 2500 so you know when you
exceed that.
