Cessna 340 Tie down versus Hangar

[endre]

I am thinking about acquiring a 340. However, it is looking a little
difficult to get hangar space around for a while at least. How should
I think about tie down versus hangar in terms of additional
maintenance/risk etc? What experiences do other people have on this
topic? Also what can I do to mitigate risk/cost?

On a pressurized plane perhaps there may be one door which can be maximally
sealed only from the inside, and it certainly is reasonble to think that
door might therefore leak when the airplane is left in the rain.

But how can windows or other doors leak with a pressurized airplane? If it
is nearly airtight then surely it ought to be perfectly watertight.

Inflatable door seals.

And the windows?

How long is "a while"?

What is the local climate?

Do you already have an airplane that could enjoy the benefits of a
nice hangar (while you are shopping for your 340)?

Bearing in mind that a 340 is a complex aircraft (pressurized,
turbocharged, retractable gear, etc. etc.), I can't think of any
aspect of a tie-down that wouldn't be detrimental to it mechanically.

Desert storage is about as good as it gets, and it ain't great.

The cabin door and emergency exit windows had inflatable seals that inflated
only when the engines were running. With the aircraft parked and the seals
relaxed rain water could come in. The operator swore by the taping method when
parked outdoors.

It is going to cost you a bit in wear and tear if you store your plane
outside. The 340 is not a cheap plane to own and $15-20,000 for a paint
job is not uncommon. Then there is interior and windows to think about.

When I got mine I tried really hard to get a hangar and was able to when I
was based in the NW (Oregon).

Bingo. I have this issue on my 340. If the emergency window is too
tight the seals get squashed and won't seal for pressurization, but if
they aren't too tight then it'll leak a bit when not pressurized.
Haven't yet found the best solution other than don't park in the
rain...

You definitely want a hanger for your twin cessna.

Options:

1) Build your own if the airport authority will let you. A good option if
space is tight since you will eventually be able to sub-lease or sell the
hanger. Cost might be, what? $50/ft sq?

2) Check around with the airport bums, err... regulars. When hanger space is
tight, people acquire and hang onto their hangers like new york apartments.
With a little "bonus" you might be able to convince some guy to move his
boat or C150 out of that twin hanger and let you use it.

The problem with hanger space is it's not allocated according to supply and
demand. When hanger space is created and administered by a goverment agency
it is basically free, but you can't get any. Just like the old Soviet
system.

Now before you all start yelling about how expensive your hanger space is,
think about the square footage and compare that with the price you'd pay for
a storage unit of that size.

[Ray Andraka]

Therein lies the problem. Here in the Northeast, where you really should be in
a hangar, many of the airports won't let you put up your own, and there are far
fewer existing hangars than there are airplanes waiting for a hangar. As a
result, the hangar rents are outrageous if you can even get into one.

I don't know where you are in the NW, but if it's anywhere in the
Seattle-Everett area, are you aware of the new hangars about to be finished
at PAE? I believe there were still some available as of a couple of months
ago, including some larger "twin size" units.
