2022 Flight Time Totals

[kennyw]

Just totaling up the logbook tonight. Thought I'd share some fun facts:

Total 2022 flight hours all aircraft: 110.8
Total 2022 flight hours in 994SP: 71.1

994SP TTAF: 1,044.4
994SP Total Time since I purchased it in October, 2017: 445.6

Since 2017 I've made the following repairs/modifications:

-Re lined the brakes twice, the first time was right after I bought it.
-Replaced a failed TinyTach.
-Removed and reinstalled the engine in order to pull the accessory case and replace a worn mag drive.
-Replaced tail wheel spring and cracked tailwheel assembly with an API spring and tailwheel assembly
-Installed an alt fail/over voltage indicator and removed (heavy) analog voltmeter.
-Installed MGL G-meter in hole vacated by old voltmeter.
-500 hr IRAN on magneto (done by Aircraft Magneto Service).

Just starting this year's condition inspection. I did a warm compression check today and found 1-3 cylinders holding compression better than 78/80. Cylinder #4 is holding 60/80 with audible hiss in intake. Its always been lower than the other cylinders. But, this time is the worst. I'm gonna fly it and check it again. But, the engine is still running strong and not burning any oil. So I'm not inclined to start yanking things off it.

As part of this year's condition inspection, I'll be installing an MGL CHT indicator with K-type spark plug thermocouples on all 4 cylinders.

Over a hundred hours a year? I'm very jealous. How did you know your mag drive was worn before pulling the case? I replaced mine a while back but the case was already off and I could see the drive was worn.

Hi Ed, the first condition inspection I did, I pulled the magneto off and the phenolic mag drive coupler had some damage to it. I was able to stick my hand into the mad drive hole of the accessory case and feel that one of the lugs on the mag drive was also damaged.

That looks the same as mine did. I wonder if there's a way to detect it without removing the engine from the airframe? I also wonder whether there isn't a better material than phenolic.

Thanks for your post. It's good incentive for me to keep working.
