I’ve always been taught to be careful to not push or pull the engine cowling or spinner, but that it was safe to push and pull the propeller. I was reading the Hartzel manual tonight and it said not to do this. I checked the POH and it said the same thing.
I thought I’d mention this, since it came as a surprise to me. Actually, I had always wondered about pushing and pulling on props, but since CFI’s, mechanics, and owners did it, I figured it was OK.
So what does one push on if your doing it alone? I find it difficult to put all my weight into the tow-bar and I can’t steer the tow-bar and reach the wing root at the same time. Ditto for pulling the plane out, though that tends to be less of an issue, because usually one can start the engine to go forward.
PS. Count me as an Arnav ICDS-2000 fan, despite all the glitches. Cirrus should make the engine monitoring standard equipment at least in the SR22.
