A difficult post

After the last oil change which we did at about 13 hours, the oil analysis showed that the amount of iron had decreased further and it was looking like it was a "one and done" incident. Per my mechanic's recommendation, I flew it for 25 hours before the next oil change.

That oil change was just performed... and the news is not good at all. This time, a considerable amount of metal was found in the suction filter screen and the oil filter. There was enough there that my mechanic grounded the plane. The decision has been made: the engine is coming off and will likely need to be overhauled. While it is possible that the engine only has to be repaired (e.g. if the metal is from the camshaft and everything else, like the bearings, looks good), I'm acting on the assumption that an overhaul will happen.

My emotional state with respect to this development is complex. On one hand, I feel kind of sick to my stomach when I contemplate the cost I'm about to pay both in money and in down time. On the other hand, I'm kind of looking forward to the process and to breaking in a freshly overhauled engine. As with pretty much everything that has happened since I bought this plane, it will be a learning experience. I'm relieved in a way that there is no more ambiguity as to the condition of the engine. The process we followed worked as intended. It gave us the answer, even though it wasn't the one I wanted, and did so before the engine's operation was affected.

I'm in the process of obtaining quotes from several service centers. Preston, the shop manager, is getting a quote from his preferred overhaul shop. While price is a primary consideration, time is as well and I'd be willing to pay a bit more if it means getting back in the air sooner. I just need to temper my expectations around how long it will take. I'm looking at probably three months minimum.

In the meantime, I need to practice my skills. I'll be doing some desk-flying in Microsoft Flight Simulator and X-Plane for sure. I'll probably go back to renting for the time being. I need to get signed off in the 172 again with an instructor as well. Although the FAA is fine with me just jumping into the plane and taking off, the rental firm isn't. I may get signed off in the 152 as well. This also means getting renter's insurance again.

Another option would be to get my taildragger endorsement, even if I end up never using it. It'll give me something to do and could come in handy in the future. I expect it will make me a better pilot if only because it'll be done in a plane that is probably more challenging to fly.

So now this blog will effectively transform from an account of flying my plane into an account of having my engine overhauled. I suspect I'm going to have a lot to write about.

    Sorry to hear the news. I hope things move along at a good pace and I'll be interested to follow this next part of the journey.

Approaching the annual

I know I haven't been posting much, but that's mainly because nothing much of note has been happening. I've been flying, but not really going anywhere in particular. The engine continues to run very well, and the plane is still solid. I was hoping to do more "destination" flying this year but, for whatever reason(s), it didn't really happen. Next year, hopefully.... On the horizon, though, is the annual inspection. It's already scheduled for mid-December, since the last annual is good to the end of that month. I've also arranged for it to be an owner-assisted annual. I'm told that every airplane owner should do this at least once and I can certainly understand why that is the case, even before I do it. I will be learning about my airplane in a way that nothing else will match and, incidentally, save some money at the same time. I'm looking forward to it. Leading up to the annual, I have been compiling a list of squawks that I want to take care ...

April showers....

I haven't been flying in a few weeks due to the weather. It has been a rather wet April and the alignment of rain showers with the weekend has been exquisite. I have nineteen hours on the engine so far. The plan is to run it to 25 hours, then do the first oil change. At that point we'll most likely switch to regular oil. I do have Camguard that I intend to use but my understanding is that, with a new or overhauled engine, you should run at least one oil change interval on regular oil without Camguard before starting to use it. If the weather is nice at some point during this next week, I may just take a half day off from work and go flying, then make up the time later.

Not much going on right now

I've put about ten hours on the plane since I got it back from the shop last December. The weather has been generally poor so flying regularly hasn't been possible. For now, I'm focusing on putting time on the engine to continue breaking it in and get to the first oil change. Oil consumption has already dropped to normal, or near normal levels so it looks like break-in is going well so far. And that's pretty much it for now. I am looking forward to more regular VFR conditions as we move into spring and summer. I'm also looking forward to flying to other places for fly-ins and other get-togethers since I missed most of them last year.
