I recently found a large crack in the Funnel-type Oil Tube (Part #H2-6204-00) on the flange where it attached to the oil pump. When we pulled the unit off we discovered that the crack was about halfway around the tube, and that it had been repaired at least once before. The unit was unsupported at the oil hose end, which surprised me as it's a fairly big piece. Had anyone developed a bracket support for this unit to avoid this very messy situation from occuring again? Thanks!

One of the best ones I have ever seen. Engine mods put it easily over 400 HP. Probably around 430 or so. I'm just glad he is alive, although he is in significant pain from the burns. Sergei walked out of the hospital because it "costs too much". He has had a bad year. My heart goes out to him.

I check it regularly, so this is something new. The left aileron is solid. The aileron bracket to the wing is tight, so the movement is within the aileron hinge or bearing. Is this something that common with the Yaks? I remember seeing an email about that before, but searching the archives, I couldn't find.

Dennis Savarese" Subject: Re: Yak-List: Yak 55M Aileron Bearings Attention to all the exposed bearings in the Yak is very important. That is, they should be cleaned and lubricated regularly. On the 52, the inboard aileron bearing is always the most difficult to clean and lubricate. But it must be done regularly. Bearings that are exposed to the elements, like the outboard aileron bearing you mentioned are particularly prone to picking up grit and grime. This of course destroys the bearings. I'm not sure about the 55M outboard aileron bearing, but the outboard aileron bearing on the 52 is unique and expensive compared to the very common 19mm OD x 6 mm (ID) x 6 mm (W) self aligning bearings.
