|

All,
Let's start a new thread.
On run up in Atlanta last evening upon cycling the prop the left cable
broke so I could not feather the prop out of high pitch. Upon return to
the FBO I opened the cowls and found a significant birds nest planted in
the prop governor area and around the pulley. I don't know if that was
the cause of the breakage but I was left with no way to feather the
prop. After much thought I decided to attempt to return to Michigan as
it was. I planned on throttling back to 17" after take off and use the
rudder trim to fly coordinated and then set the autopilot. The four
hour flight was totally uneventful other than the noise due to the
uneven RPMs.
I am very interested in the opinions of others and also where to get
another cable.

I wouldn't have done that.... fly with no way to feather. You can use an automotive cable that will work until you get a commander replacement. Are you sure it wasn't the prop governor instead of the cable? (I just had both our prop governors rebuilt in the last year).
Again - I wouldn't fly with no way to feather.....Let's see what the grey hairs say (oh wait - I have grey hair)

I found the tower and pulley on top of the prop governor and the cable was broken and loose on one side of the pulley. On the other side of the pulley the cable was tight. The mechanic that looked at it said that there is a spring that keeps the governor in high pitch in case of the cable breaking.
I am very interested in what the issues are of running the engine with the propeller at high pitch and throttled back to 17”. Prior to heading north I took a side trip to an airport 20 minutes south for fuel and to test the performance and temperatures and vibration on the airplane. Other than the noise of the unsynchronized RPMs there didn’t appear to be any issues.
Again, I am very interested in hearing from those that have much more experience than I. I also have grey hair.

Don,
From my perspective (also grey) is that if you lost that engine, its windmilling prop might have dragged you down to the site of the accident.

Good Morning bobf,
I think I can qualify as a grey beard!
There are times when I would fly without the ability to feather the propellor on a twin engine aircraft.
It all has to do with evaluation of the risk
Fact is, I received my multiengine rating in an airplane that was not equipped with feathering propellors and that would not maintain altitude with one engine shut down. That was a Cessna Bobcat more commonly referred as a Bamboo Bomber. I also flew many Twin Beech Model C18s that did not have feathering propellors installed. It was before my time, but the first Douglas DC-3s were flown without full feathering propellors.
So, the risk is just another one of those which we all have to evaluate each time we fly. Lots of folks will never get in a single engine airplane unless they have a parachute equipped ejection seat to sit on!
However, in the case in question, I doubt if I would have flown the airplane without getting a ferry permit and flying only in compliance with the restrictions imposed by that permit.
In my book, the greatest danger would be in getting caught doing something illegal.
The risk involved in flying without a feathering propellor can be mitigated by good flight planning, but the risk of certificate action is difficult to avoid.
Happy Skies,
Old Bob

Don-
I think we’re all equal parts glad that you didn’t have any trouble- and glad you can see that risk now too.
All of us commander drivers need to stick together- thinning the herd is for other people.

Hey old Bob!......Once again our past lives seem to share a common thread. I also got my multi in a Bobcat based at MDW when it was listed as the world's busiest airport. I think Cessna dubbed it the Bobcat to give it a more macho sounding name for the military model which was the T-50 I think. You left out the often used nickname for the civilian model: Useless 78 (UC-7. If anyone remembers the old TV series Sky King the original Skybird was a Bobcat. I enjoyed my time in ours & with a light load & resonable altitude I was amazed at how much time you had with one back at idle to pick out the site of your impact. Later, in the midst of a hot & humid midwest summer, I found myself giving multi instruction in an early Piper Apache for a school who's policy was to put 3 students & an instructor in the aircraft on the theory that the back seaters would absorb some of the training procedures before taking their turns in the left front seat. One time when we landed to play musical chairs, one of my back seaters jumped to the ground & vowed that however long he lived he would never again allow his feet to be separated from mother earth........for a minute or two I seriously considered joining him. Fortunately our friendly FAA inspector convinced the boss that this training procedure was not in the best interests of aviation safety. Also I believe we were consuming more barfbags per hour than fuel. I do believe that the old Bobcat with its "Shaky-Jakes" could have pulled it off much better than the Apache with its "Little Lycs". Keep 'em flyin' Old Bob....Dan the desert duck.
