Dear Commander Drivers,
Thanks for the good advice on the center bladder. After replacing the other
eight bladders, which were of varying age, I have decided not to replace the
center bladder at this time as it has no apparent leaks and was replaced new
(according to the log books and receipts that came from the previous owner)
in 1993.
The requested information about where leaks would appear if the center
bladder started a leak was for future reference.
As a point of reference, about how long should a new bladder last?
Best regards.

Moe,
We recently replaced the cells on the right wing. They were 1978 vintage.
The left wing (same vintage) is still holding up.

My 500B has a faint smell of gasoline, especially in the baggage compartment
also. Even though I've had the sump apart and no apparent leakage, it is
still there. However, I did notice the smell increased slightly when one of
my wing tanks started leaking. That and the big blue stain on the fuselage
under the wing tipped me off.

I took my center tank out last year and had it checked and rejuvenated. It
is I believe 44 years old. The main thing you want to do is keep the tanks
full so they do not dry out.

Just replaced my bladders in 411VV. 1951 , 1952 were the dates of
manufacture stamped on the bladders. Only one of five had been redone and
that one was rebuilt in the 70's.

I couldn't resist, now that you guys are talking about the perceptiveness of
a Commander pilot.
When the first VW bug came out, there were many quotables for that (what we
called an excuse for an automobile) car. This one was particularly popular:
This guy was a car fanatic and he could tell you blindfolded everything abou
a car just by hearing it being started. Playing a trick on him, his buddies
took him to a toilet, the kind with the overhead cistern and chain, and
flushed it. He thought for a while and said it was a '57 VW Bug with a bad
misfire.

HI KIDS.
I just got back from my Mothersday trip in triple 2. It was a great
ride. Went over at 15.5 (29 X 2550) and 205kts, returned at 9.5 (31.5 X 2550)
171kts (must have had a tailwind both ways??) that is 188kts two way
average!! Pretty good for an airplane almost as old as me.
The weather was interesting, but the outcome was never in doubt. We were
on top most of the way both directions. The new engine is spectacular.
Nether engine used any oil on the trip and the new engine didn't even leak any,
Yippee!! jb

The outside of the cell is coated with a lacquer like material that protects
it from Ozone and the elements (remember the article in the last FGN about
fuel cells??) The inside cannot be coated, so, we must keep them wet. jb

bilbo,
My understanding of the chemistry is that it's the same thing that
happens with most rubbers and plastics - hydrocarbons tend to react with
the plasticizers which are used to keep the rubber compounds flexible
and sealed. As long as the tanks stay "wet", the plasticizers stay
rubbery, but if allowed to dry out after this reaction has taken place,
they harden, shrink, and begin leaching from the rubber and cloth.

Subject: | New Commander Pilot with Questions |
--> Commander-List message posted by: "Ray Mansfield" <hcourier@cox.net>
I've just recently started flying an Aero Commander 680 FLP for a company in
Ft. Walton Beach, FL. I suspect many of the people on your web site have years
of experience with this machine. Sooo...I have a few questions.
1. When the plane is in the hangar, any fuel in the right aux tank will
drain into the center tank in a short time. This occurs even if the
fuel selector is set to "OFF". It even occurs in flight in that the
right aux tank is used up faster than the left with the engines at
approximately the same gph fuel burn. Any thoughts on why this
is happening.
2. The pressurization system only gets about 2,000' differential at
10,000 ft altitude. The cabin has been checked for leaks and none
of any consequence were found. The door seal is new and the
seal pump seems to be working. If I just climb, say, to 15,000'
will just the fact that the turbos will be putting out more pressure
cause the differential altitude to increase beyond more than
2,000'. Right now there's no real benefit to having the
pressurization as it doesn't work good enough. This airplane has
the Mr. RPM engine conversion to the IO-720 Lycoming.
Thanks,
Ray Mansfield

Hello Ray,
What is your tail number and serial number? Sir Barry Collman, Aero
Commander Historian, needs to keep the chain of ownership updated.
As to your pressurization troubles, if you've checked the door seal,
emergency exit seal, window seals, control column seal and rudder peddal seals,
you
need to check the ducts and clamps coming off the pressurization manifolds.
Don't overlook any of the ducting along the way from turbos to cabin.
Also, check to make sure that the inspection / access plates under the carpet
in the cabin are sealed. The next most troublesome leak area would be the
wing roots, which will require dropping the headliner.
You need to run fairly high RPMs on the Mr. RPM conversions because you're
sharing the turbo output with the engines. More mass flow = more air for the
engine and cabin.
If you've checked for leaks -- and I mean really checked for leaks as
described above and you're still not keeping a cabin, it may be due to the cabin
pressure controller, which isn't young by any standard.
The fuel "transfer" is due to a leaking fuel shut-off valve most likely.
There are several of these electric gate valves in the airplane and are used for
hydraulic, fuel and oil (on the original 680FLP) shut offs. R & R the
corresponding valve.

1. When the plane is in the hangar, any fuel in the right aux tank will
drain into the center tank in a short time. This occurs even if the
fuel selector is set to "OFF". It even occurs in flight in that the
right aux tank is used up faster than the left with the engines at
approximately the same gph fuel burn. Any thoughts on why this
is happening.
The fuel valve is leaking internally. I allows fuel to transfer. They need
new seals. jb

Just a thought on this topic for all Commander operators with more than 156
gallon fuel systems. That would be Commanders with geared Lycomings and the
MR. RPM converted airframes. OK... And the few Gary Gadberry 223 gallon 500
A/B/U/S series.
When using the outboard tanks, keep in mind that more fuel than is required
is sent to the fuel metering system (either pressure carburetor or Simmonds
fuel injection) and that by-passed fuel returns to the center tank.
If one were to switch to outboard tanks too soon (or as in the case with our
new friend with the leaking fuel shut-off valve), there is no room in the
center tank for this return fuel to go and it dumps overboard.
So when is an OK time to switch to outboard tanks? As soon as you see the
main or center fuel system come off the full peg and begin to indicate anything
less than full, you have room for by-pass fuel. That would be in the 135
gallon indicating range.
There are two schools of thought on using the outboard tanks. Either
one-at-a-time, or, switching to double outboard but with 15 minutes of staggered
time so if you need to run the tanks dry, you don't have two closely occurring
adrenaline rushes to recover from.
The devotees to single outboard tank feeding run that way because in the
event of a total electrical failure, the tank selector valves fail in their
present position and that scenario would leave you with only outboard fuel that
is
NOT useable in all flight attitudes and not all that much fuel to get over the
mountains or ocean with.
Just something to think about, along with meteor strikes and whether you
forgot to run the dishwasher before you left on this trip.
