I couldnt imagine< mike, just losing a wheel weight on a car shakes.mtv wrote:Back in the mid eighties, a Navajo crew from Canada were making a night approach to Fort Yukon with a load of passengers. Loud bang, big vibration, then nothing. Right engine shut down due to failure. Crew assumed it was a simple engine failure. Airplane wouldn't maintain altitude. CoPilot looked out with flashlight, and right engine was GONE. Still couldn't figure out why the plane wouldn't maintain altitude on one.
They wound up belly landing on a gravel bar on the Porcupine River (middle of winter, so all frozen), did a really nice job. And, had called in an emergency.
Turns out the right engine had come off the mounts, but was being held suspended behind and below the wing by wiring, plumbing, etc. Lots of drag in that configuration.
The Native Corp went upriver and towed the thing down to FYU, but the entire airframe was pretty much junk as I recall, from the vibration.
I've had one prop tip depart a plane, and it was impressive when three inches of blade left suddenly. Power back and shut down, and fortunately a nice gravel bar to land on.....
Vibration from imbalance is amazing.

....as opposed to being a stupid old pilot ....I let a 40 kt. tailwind put my Citabria on it's nose while on the ground. There was a terrible metalic sound as the prop chewed into the asphalt. I yanked back on the stick and the engine kept running.
Embarrassed I took off without inspecting the damage and flew 1 hour back to the home base. The prop vibrated a bit and cruise speed was down about 20 kts. When I landed and shut down ....the prop tips were bent back about four inches at a 90 degree angle.
The boss put on a new prop...no engine tear down or nothing. I flew that engine and new prop for several hundred more hours on pipeline patrol. I survived and the engine never developed a problem.
God looks after children, drunks and foolish young airmen....sometimes!
Caldwell Industrial Airport Users:
You may have noticed that there is commercial construction activity on Skyway Street -- approximately 1/4 mile east of the Flying J complex -- a new 80,000 sq. ft. manufacturing facility.
Next week (June 18-22) they will be setting various pieces and parts of the new building using a crane that will stand approximately 80 feet in the air. It will be a little over 1/3 of a mile off the extended runway centerline and well below our FAA safety surfaces. I expect that the crane will not be lighted at night, but will remain erect.
This message is provided to advise you of an activity going on in the vicinity of the airport that's somewhat out of the ordinary. The construction and crane should be of no impact to any of the normal aerial activities at our airport. [Valley Air @ Hubler Field has been given this same info]
Please contact Rob Oates if you have any questions about this announcement.

It was reported to me by the pilot that the prop vibrated a lot, but he flew the plane about 50 miles back to Happy valley pipeline camp so he could have a new prop brought to him. Must not have vibrated too much. But it was winter and about 30 deg.below. You need two things to make aerial shooting work well, good pilot and good gunner. If I knew how to download an old slide, I have pictures of the prop.
