Ready for another year

 Annual done, check flight OK, refueled, cleaned.... 

Annual 2021 part 4, done

 Last part involved removing access plates in the fuselage and wings (did not have the phone with me when I was under the wings). and check things out. I found no new problems :)

As all safety critical parts are done, I filled out and sent in the paperwork. Already got an OK reply so I am now good for another year. Only thing left to do is checking/re-greasing the main wheel bearings.

Annual 2021 part 3

 The traditional spark plugs also looked good, gap was ok...

Cleande the airfilter, exchanged the oil filter and then filled upp with 5.5q of oil.

After this I reinstalled the cowling, took it out of the hangar and mad a test-run. Got good values and reaction to mag-checks so all is good. All checks FW-forwards are now done, hopefully only one more work session before being done with this annual.

Annual 2021 part 2

 This Thursday I got around to making a warm-up flight and then change the engine oil. Less mess this time.

I then checked the spark plugs, shown is one of the lower e-mag plugs. I will exchange them but I think they are perfectly fine and would probably have worked fine for another 100 hours.

 

Oil plug back in place with safety wire.

Annual 2021 part 1

 At 97 hours and with 30 days to the deadline, it is time to start the annual inspection.

This year I started at the both ends. First I took a look at the front, in general everything firewall forward looked great.Engine controls including the cables still looks like new and all cotter pins are in place :)

There is a small leak between the injector house and the sump, nothing I worry about.

I will remove the magneto to perform two service bulletins in a few days, I checked the timing anyway just to see the status. It has creeped a bit, it should go off at 20 degrees before tdc but it was triggered at 22-23 degrees. I set it back to 20 for now. I have not seen any difference in the logs between flights directly after the last annual when I knew it was at 20 and the flights that have been flown recently. Not surprising as at all setting but full power the magneto will lag significantly behind the e-mag. 

Speaking of the e-mag, a small cable that sits between two poles on the connector was broken, allowing the e-mag to use the more aggressive timing scheme.... again I have not noticed any downside to this in the logs but I fixed it as I want a greater margin and the fuel savings from the more aggressive timing is barley noticeable.

To be done FW-forward is to check&clean or exchange spark plugs, clean the air filter, perform the mag SBs and do an oil&oil filter change..

While at the front I also checked the prop, gear legs, fairings, brake lines and tires. All looked good, I plan to re-grease the wheel bearings but it might have to wait until slightly after the annual as I do not have any good lifting solutions at the hangar now.

I then removed some fairings and panels at the back. Looks great, nothing has come loose and it looks just as clean or dirty as it did during final assembly.
