| Subject: | B and C pad mounted alternateor |
Anyone using B&C's pad mounted 20 amp alternator as a primary?
I checked my consumption and with everything on (exception fuel pump) it is 22
amps.
I have 500 hrs on Van's alternator and dread having to pull a prop out on a trip
to replace a belt or the alternator.
Thanks.

A properly tensioned and aligned belt will last a long time.
I had 2200+ hours on one belt (my AA-1B) before I changed it. It was
showing signs of cracking so it was a preventative move. You should
have a lot of warning before a belt failure. It should be on your
checklist at annual and damage is easy to see.
Now for your 'dread'. Next annual put a 'backup' belt on the nose of
the engine and ty-wrap it to the forward lift ring to keep it out of the
way. I have seen the 'replacement' belt be unuseable because the
primary lasted so long and it was just dried out. I don't have any data
but you should get at least 1000 hours out of a belt so change it during
an annual or when you pull the prop for some reason. Belts are cheap.

Good advice Linn. I will seriously consider it.
How about the alt? Anyone has failure hours in service data? My first one lasted
200 hrs. This one has 500 hrs and I have a long trip to take next month.
I see black powder on the alt and I am worried.

That should be 'conditional inspection' not 'annual' .... old habits are
hard to break.

You need to find out where the black powder is coming from. I suspect
the belt. Look at the baffling around the belt for signs that the
clearance wasn't enough. I've read (here I think) about some original
installations not having the flywheel and alternator pulleys aligned and
needing modifications on the alternator mounting to make it fit
properly. That may have been a Plane Power problem though. Have a safe
trip.

As already pointed out an alternator belt tends to last a long time if not
misaligned. If you have reason to pull the prop however, replacing the belt
is always an easy preventative maintenance step. The standard 60amp
alternator (B&C or Plane Power) is easily replaced without pulling the prop.
WRT only running the little 20 amp pad alternator, I suggest you are trading
good for not as good:
- you will be limited to a day VFR aircraft
- no margin at all to charge the battery(s) after engine start
- the little alternator always running full blast
- the only B&C alternator failure I've seen was one of these pad units - the
breakable coupling broke.
- any auto part store will provide an acceptable alternator if you get stuck
someplace (assuming you are using an internally regulated alternator like
the Plane Power unit). The little B&C pad alternator is a "send it via
FedEx" process.
On the larger picture, the alternator is not the most reliable element in an
electrical power distribution system, it is the battery. This assumes you
don't design in a single point failure such as a single battery (or two
batteries always in parallel), single master relay, a single ground
connection, single avionics master switch, or similar. Adding an extra
alternator (if that is your direction) protects only from the primary
alternator failing. Having a robust battery power distribution with a
single alternator and adequate battery amp/hr capacity, I offer, is better
risk mitigation.

| Subject: | Re: Flying the Hudson through NY and to Washington DC. |
Last Monday Sept. 9, we loaded the RV-10 for a 3 day visit to NY and Washington
DC. The weather gods were definitely smiling on us as we had tail winds and visibility
of 50+ miles.
Enroute to NY. we had a clear view of Niagara Falls as we passed just north of
it, also an excellent view of the Finger Lakes as we passed overhead.
First stop was West Chester Co. Airport in White Plains NY for Customs. Only a
few "Quality" minutes with these officers of the law and we were on our way.
The flight down the Hudson River turned out to be easier than expected. I was well
prepared having taken the on-line course as suggested. The NY TAC Chart is
a must for his flight as it sets out clear instructions with mandatory reporting
points ect.
After the flight down the Hudson and a lunch and fuel stop in Farmingdale NJ we
continued to Gaithersburg MD near Washington for what turned out to be a fantastic
trip.
