mocfly Posted July 10, 2013 Report Share Posted July 10, 2013 During my flight from Chattanooga to NJ yesterday I experienced what I can best define as a significant "shudder". Here is the background Departed Knoxville full fuel 2 passengers and plenty of baggage. Initial climb to 7500ft. with a cruise set at 5400rpm. Increasing clouds required a cimb to 9500ft. The flight progressed uneventful until about 4 hrs. where the 1st. shudder occurred. The initial shudder felt like something had become detached an hit the aircraft or there was a high speed miss. It last long enough for me to feel it but not long enough or hard enough to be concerned. It did however wake me up. The next event occurred after we had exited an area that had us in some pretty good precip. This occurrence lasted a little longer and felt strong enough to think that a prop blade was loose. From 5400 I reduced the rpm to 4600 and while the prop was ok and the rpm was steady the engine felt like it was running rough. This time i was concerned enough to start looking for nearby airport. Increasing to rpm to 5400 it was smooth as glass. This happened one more time before my descent into KCDW where the flight ended without any further problems. During my descent the engine responded normally with quick responses and all instrumentation in the green. After landing a walk around showed no abnormalities. My direction of flight was 060 with a 8-10kt wind from 260-270. Thoughts or Questions? Link to comment Share on other sites More sharing options...
