I stand corrected, the repairs were 28k, there was an additional 2.5k for painting the repaired areas. The annual itself (no repairs) was 3k. Then there were 6k of random items, like a wheelen power supply they had to change.

So, as the airplane was so long waiting to be repaired, the annual lapsed. So I asked Don to do the annual after the finished the repair. Roughly, the cost was: 25k corrosion repair, 12k annual. The initial estimate for just the corrosion repair was 13k.

He did reach out to me, I shared the facts. For transparency, these were my responses to him: > In a nutshell? It took 1yr to do the repair and it cost 2x the initial estimate. I can give you more precise numbers, as the invoice was 3x the initial estimate, but it included a annual inspection as well. He was not very responsive either (although I was not the type of customer calling him every week). He sometimes seemed upset by me calling. > On the flip side, the airplane flies perfect, no issues in the last 3 years since I got it back. > I just checked my invoice, and the corrosion item was 25.5k, I think their initial estimate was 13k. > My corrosion was on the LH aft stub spar cap. They ended up replacing the whole stub spar, not just the cap.

That's news to me! Thanks for sharing.

Curious about this, is there any way an insurance company could cover this?

We need a system to track the history of airplanes, I guess it would be of great value for buyers...

I hope he is not planning to "hide" the corrosion (and any evidence of it) and put it for sale...

I was mentioned on a thread about corrosion and when I tried to go check it out it seems to be gone. Any idea what happened?

Aside of the 1980's market downturn, that most likely killed the PFM 3200, does anyone have first hand or reliable information on how well (or bad) the engine would perform? I mean performance, maintainability, dispatch rate, etc.

I had some surface rust in my steel cage in the belly, and used Zinc Chromate Primer. I know is nasty from health / environment, but also I think is one of the best rust preventing primers.

What I feel is like a sudden, short, desceleration. The airplane doesn't shake much. It something that last 1 second. If I have to describe is like if the engine would shutdown for 1 second and then relight again. I've never seen water in the fuel, the airport where I fuel has a pretty good record of not having water in the fuel. The airplane is hangared all the time. As far as I can remember, it never missed a beat running ROP. This time for instance, the leanest cylinder was 75F LOP, while the rest were all around were between 30F and 50F LOP. If it is a random thing result of running LOP I would be ok, my main concern is if there is something else going on that might end up with a loss of power in flight. One additional peace of information, not sure if it is relevant, I'm a relatively "new" Mooney driver, the mixture control "lags", what I mean is if lean the mixture, say 1/2 turn, it would take maybe 10s for the fuel flow to stabilize in the new value. This happens either leaning or enriching the mixture. Not sure if this is normal or not. Some times I would make a full turn without seeing any change in FF, and then after several seconds the flow would start moving to the new setting.

It does not. I haven't noticed any backfire ever.

I don't see anything really telling by looking at the EGTs. Around on of the misfires there is some change in the #3 EGT, but I'm not sure. Can a nozzle act up like this? The engine runs fine just except this stumbles every now and then. The GAMI spread is 0.4GPH. Would there be other symptons for a sticking valve? The magneto was IRAN 100 hours or so ago, and 20 hours ago it was taken to Aero Accessories at Van Nuys, they bench tested and said it was perfect and was not worth tearing it appart.

Hi, I have a recurring issue (say 1 out of every 3 flights) when in cruise the engine stumbles (misses a beat). It is noticeable. Maybe in a 1hr flight it happens 1 o 2 times. Always while in cruise. My last flight, yesterday, it did it 3 times. This is my flight data from yesterday: https://apps.savvyaviation.com/flights/shared/flight/10152924/66425963-23ae-401f-8ad9-abe3f3d3e8c0 One of the stumbles happened while I was leaning the mixture to get a new measure of my GAMI spread. I did a mag check while still LOP and the engine run smoothly on each mag. I asked Savvy a couple of times, and nothing conclusive yet. I opened a new ticket today, but I'd like to see if you guys have any thought.

As I read this post, two thoughts came to my mind: Why would a relative large company like Lasar use ChatGPT (or a similar LLM) to craft the post? Don't they have people that can write a genuine letter to its customers? You can tell that this was generated by AI because of the "—" or the " instead of the ”. When I had the corrosion issue on my first annual inspection, Maxwell ordered a new aft stub spar from Mooney. What Maxwell charged me for the spar was ~4.6k, and labor was ~20k. I assume that Maxwell adds a markup to the parts, so most likely Mooney price was lower. It surprised me how "cheap" the part was, even more considering that it was backorderd and Mooney had to manufacture a new one. Talking with Patty from Mooney I know that they did a batch and they had a few bad parts that they had to scrap. So I'm quite sure the spar was priced below cost.
