At about 4:30am this morning there was an odd system problem on the Matornics email server, causing many mail files to become marked as "read-only". This wedged many of the List filters causing all sorts of weird behavior. Perhaps the oddest was that an innocent message from Walter Critchlow, kept getting posted instead of the actual incoming List message. If you receive this message, and sent a list message to any of the lists shown below between the hours of 4:30am and 5:15pm PDT on Sunday Apr 10th, your message was one of the ones that got subverted. Please repost your message to the respective list.

As I climb I keep the MAP even on both engines and the plane climbs straight, no yaw or rudder trim required. If I kept the turbo levers even, the aircraft would yaw to the right as the left engine MAP would climb higher than right with even turbo levers. In other words, when the MAP are equal the airplane flies trimmed and straight. (It just takes more right turbo lever movement than left to be trimmed and straight) Ray M. ----- Original Message ----- From: Subject: Re: Commander-List: Pressurization, Turbocharging problem > --> Commander-List message posted by: YOURTCFG@aol.com > > > In a message dated 4/4/2005 8:10:57 P.M.

I would like to put in some sort of bubble window instead of the normal flat window, pressurization is not an issue. There is a oddity in that one of the starboard windows has been modified into an additional emergency exit and is therefore larger than the normal window. The co-pilot side window also needs to be replaced and I would like to put in an FLP window with a vent window within it as I have on the pilot side. Does anyone know of a source for this type of items?

I'd be worried if the MAP were even & the airplane was yawing (gauge prob?) much more than if the turbo levers were in different positions. I'd have to reinforce the earlier suggestion that perhaps a butterfly valve is warped. With these airplanes and their 50-year-old technology, I think the turbo installation is always the weakest link. I have a 500-B with the RayJay turbos, with electric wastegates. My left engine always runs out of boost before the right....to the point where at 11,500ft, with both engines reading 25" MAP, my left engine wastegate limit light is "on", and the right engine wastegate still has 20% of its travel remaining (no limit light). If I judged by wastegate limit lights, I'd be flying sideways when both lights were on :-). I've replaced ALL FOUR turbos twice in the last 6 years, and both wastegates once. It's more headache than it's worth....except when leaving Truckee (6,500MSL) in August at 1PM when it's 85degF out, at max gross....then those turbos are my best friend! /J ----- Original Message ----- From: "Ray Mansfied" Subject: Re: Commander-List: Pressurization, Turbocharging problem > --> Commander-List message posted by: "Ray Mansfied" > > Hi jb, > > Thanks for the comment.
