Another expensive annual this year

How many wet vacuume pumps have you had installed? The pump alone is
$1850
with the separator listed at $495 at Aircraft Spruce. Add fittings
and
hoses to that.. He said that the tips and stab tip were $1000 for
the
parts. It is pretty clear that you have never had any of this stuff
done.

No, what's clear is that you have no real idea of how maintenance works
in the real world of light piston airplanes.

Who in the world would buy a new wet pump and separator from Aircraft
Spruce? Certainly nobody I know. Those things last essentially
forever, there were tons of them manufactured decades ago, and they're
everywhere. You can have one overhauled for much less than the cost of
a new dry pump, and you get old ones from any salvage yard. Any
mechanic worth his salt knows how to do this. The mechanic who just
orders new from Aircraft Spruce is going to cost you a lot of money.

I guess the guys that are making the new ones must be a bunch of idiots not
to know this.

No, they're very smart. They realize there are plenty of Rapoports
out there

A glance at any phonebook contradicts this statement. Personally, I would
install electric instruments with dual alternators and get rid of the vacuum
pump, hoses, filter and instruments.

Mike,
My google search of electric AI showed reliability problem with
'affordable' units such as what stated by Paul Bertorelli below:
===================================
I have on my answering machine here a message from a reader who bought
five
R.C. Allen electric AIs for a fleet of training/charter aircraft.


Four failed within 100 hours of use. Numerous other reports of
premature
failure, too.


That's not to say no one gets good service from these. But they seem
problematical.


No reported problems with the AIM units from BFG. They're twice as
expensive, however.

Mid-Continent has a new one that is supposed to be pretty good. I don't
have any plan to actually do this but getting rid of the whole vacuum system
is pretty appealing when it is only running one instrument.

What is the ratio of vacuum system failures to total electrical failures?

Anybody?

Can a completely separate and independent electrical bus be installed?

Mike,
I checked the price ant it costs close to $4K!! I was hoping to get
some recent data showing
improvement in the RC Allen electric AI reliability.

Is that with their emergency power supply or just for the instrument?
