Jammed Elevator

How difficult would it have been to land the aircraft using only
power, rudder, and ailerons?

It would have been possible I think. But to make that landing I would
want a long runway and some Crash/Fire/Rescue resources. The closest
place is about 30nm away.

Did you have some reason, not given in the narrative, for believing
that you would be able to return the elevator to at least its current
position?

Yes. I was able early on to push the yoke forward slightly, although it
took a great deal of pressure to do so. I knew there was some risk of
making the situation worse, but felt that I would be able to get the
elevator back to a workable position if need be.

Did the fact that you were ready (and able) to bail out if necessary
influence your decision-making? (In other words, would you have done
the same things if you knew you had to live [or die] with any
irreversible negative changes you imposed on the situation?)

I can't honestly answer that. I have made over 700 jumps so the thought
of leaving the airplane isn't a big deal. Having the parachute does
open some options, or at least reduce the risk of death.

I fly a Cessna P206 hauling skydivers. Today on one of the drops a
glove somehow managed to become jammed between the mass balance and the
end of the stab which jammed the elevator in about the 1/3 "up"
position. I could see two fingers sticking up above the elevator with
something flapping on the underside. The airplane was pitching up and I
had to roll into a bank to slice the nose down to keep from stalling. I
went through several repetitions of that until I found a power setting
that lessened the pitch-up, then I was able to force the yoke forward
slightly and stablized in a slight descent at 80kts IAS. I got the boss
on the radio and headed the airplane toward a deserted area that would
be okay to bail out over if needed and would be a good place for the
airplane to crash if it came to that. The jumpers had exited at 13000,
I was at about 11,500 when I got things stablized. I got ready to
bailout (tightened the leg straps, tightened the lap belt, felt the lap
belt release and the ripcord handle) and then planned on how to fix the
problem. I decided to try and force the glove out by moving the
elevator. I first pulled on the yoke and was able to get almost full up
elevator but it was still not free and took a great deal of effort to
move the yoke. This of course pitched me up sharply so I rolled left
and as the nose started down rolled level and pushed the yoke forward.
I was only doing about 60-65kts when I pushed so I wasn't worried about
breaking the airplane, but I'm here to tell ya a 206 makes some odd
noised when you push that hard negative. G I think it was the air
over the vent intakes...weird sound. The elevator was still not free as
I pitched over, I was thinking it was looking more and more like I was
going to have to jump...I pulled hard on the yoke and this time things
came free. The glove (or whatever it was) was gone and the controls
now worked normally. A gentle descent and landing followed by a close
look at the airplane. The only damage was a slight bend in the stab
top skin where the glove was jammed. (The flightsuit can be cleaned G)

One risk of hauling skydivers is that a jumper may have a parachute open
on the step which can lead to the tail being damaged or removed from the
airplane. Because of this I've thought about what I would do if that
should occur. I've even practiced flying with the yoke held in one
position to simulate a jammed elevator. Today it paid off.

It sounds like somebodys joke almost killed you.
Was the glove present on takeoff?

Either way, thanks for the nice tale. The part about using either
a turn or a reduced power setting is invaluable to the rest of us.

I'm sure it wasn't there before takeoff. Part of my pretakeoff check is
to look at the trim tab to confirm it's setting.
