New TBO Poll (Turbo and P Models)
POLL INSTRUCTIONS
------------------------------------------------------------------------------ If you have ever had a Skymaster Engine overhauled/replaced/remanufactured, please select the number of hours on the engine at that time. If you have had more than one engine overhauled/replaced/remanufactured, please answer the poll based on the engine MOST RECENTLY done. If two were done at the same time, flip a coin (literally). NOTE: This poll is for TURBOCHARGED or P-MODEL skymasters only. If you have a normally aspirated model, please use the other poll. If you have suggestions on how to improve this poll, or ideas on other topics that you would like to see incorporated into a more formal survey, please comment in the thread "Ideas for TBO Survey." ----------------------------------------------------------------------------- OPTIONAL DATA If you have time to comment more fully on your TBO experience, please attach a message to this thread and answer the following questions: 1. If you have had this experience with more than one engine, list the times for the other engines. 2. List the age(s) in years for the engines at overhaul. 3. WHY did you decide to overhaul your engine(s) at that time (if there was a mechanical problem, please be specific). 4. Did you ever do any major repairs to the engine(s) before overhaul (eg: top overhaul, etc.) If so, please list the type of repair and the engine hours at which it was done. 5. Any other comments you care to make concerning your TBO experience. I will perform a more thorough spreadsheet analysis on the supplemental data and post it for everyone. Thanks for your participation! Last edited by KyleTownsend : 03-07-05 at 07:06 AM. |

To be clear, shouldn't people report only on engines whose performance or condition required an overhaul (as opposed to you wanting to do it when it didn't need it or regulations unrelated to the engine forcing you to do it) and such condition was not the result of infant mortality of a new part or workmanship issues? Specifically, don't report an overhaul of a healthy engine due to a prop strike. Don't report an overhaul of an engine because you put in a new magneto and the engine gear disintegrated inside the engine. Don't report an overhaul of an engine because your mechanic left something loose on last week's oil change, with all the oil running out and the engine seizing (although I'd blame the pilot as much as the mechanic). Am I right here? We want to measure engine reliability and life, right?

We overhauled the Rear Engine at 819 hours due to a cracked case. At that time, the engine was 18 years old. It was a factory reman.
According to the log books, the previous owner had replaced the original rear engine with a factory reman at 686 hours TT. The cause of this replacement is unknown. The engine was 8 years old at the time. The previous owner had also overhauled the original front engine at 1025 hours TT. The cause of overhaul is unknown. The engine was 13 years old at the time.
