I was demonstrating engine outs last sunday... Temp was about 4F... Taxiied
all the way in and shut down - and the blades went into feather on both
engines... mutter mumble..
Restarted shaking, quaking and banging until the blades unfeathered Ran
the engines up to 1500 to set the locks, idled, and then shut down...
*^(%#$@ blades feathered again... really mutter, mumble and other anglo
saxon entreaties
Started up again shake, quake and rattle - entire airport now watching and
pointing once the blades unfurled ran the engines up to full throttle for
20 seconds each, idled, and shut down... Stayed at flat pitch finally.. The
feathering pins were stiff in the cold and once retracted, the usual 800 rpm
not enough to sling them back out... Be careful about simulated this or
that in extreme temps..

stop. Then I goose it every couple or three
minutes--I've never noticed how frequently.
