Dear Listers,
My sincere apologies! 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.

Again, my sincere apologies for the problems. I was doing my Taxes (!)
today and wasn't keeping as close an eye on the Lists as I normally do.

Hi jb,
Thanks for the comment. 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)

--> Commander-List message posted by: "Tom Fisher" <tfisher@commandergroup.bc.ca>
Gentlemen, I need to replace all my side passenger windows on a 680 FLP.
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?
Tom F.
680FLP Mr.RPM

Ray,
In my mind, that definitely sounds like a wastegate problem rather than
simple rigging, especially with the mechanical gates. 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!
