Bob, ( and all) I am fortunate to have had a Dad that didn't see the need to
hire anyone to do anything for us either. I learned to do pretty much
everything that needed to be done, and since he was a machinist/millwright
by trade, learned to make the tools needed that I didn't have. And had a lot
of fun in the process.
Regarding the LSA machines, I have not read that new stuff closely enough to
be able to say. I live in the Sacramento CA area, and there are a lot of
experimentals around here, and I'm sure the LSA scene will explode too.
Should be really interesting.
Wes

>BTW, what's our position regarding LSAs now?
It depends, actually. If it's an experimental E-LSA (i.e. built by an owner)
the rules are similar to the ones for experimental aircraft. If it's a S-LSA
(built by a company and sold to an owner), maintenance is by either an A&P
or via someone who has attended a repairman's school for that model (off
hand, I haven't heard of any of these being set up yet.)
There's more there, but that's a quickie look. Take a look at
www.sportpilot.org....it's the EAA's hub for LSA information.

Hello, I am not an A&P but thought I could get some good info
on this list from others that are. I own an auto salvage so I am somewhat
mechanicly inclined but airplanes are somewhat different than the
automobiles I deal with. I am building an Aerocomp Comp6 with an IO540 KIA5
engine and this is the first airplane I've attempted to build.
Couple question's I'd like to address is: Do I need a fuel
primer for this engine ? My A&P seems to think so. Bu I don't understand why
with a fuel injected system.
Another question: The Comp6 is a high wing plane and I was
told I did not need a boost or auxiliary electric fuel pump either but I
believe that the minimal weight added versus the redundancy would be
benifitial. Any light on this appreciated.

First question: Is the plane a LOW WING or High Wing? If low wing YES BOOST
PUMP
Second: Do you have a Left - Right fuel feed system? If so YES BOOST PUMP
Third: You are using a Fuel Injected engine. YES BOOST PUMP
Whenever the fuel has to go UP hill as in a low wing plane a BOOST PUMP is
required. It is a SAFETY DEVICE. Especially if you run one tank DRY. You will
need all the help you can get to bring fuel to the engine. You don't want a
long delay and pray for gravity to work. Gravity may not be there in the
direction you want all the time. Think 'G' Forces.
Again, with a fuel injected engine one of the starting procedures it Throttle
1/4", Mixture Full OUT - Cutoff, PRIME, Boost Pump ON ... CRANK ... When
engine starts to fire ADVANCE the MIXTURE. So in this case the BOOST PUMP is
supplying the fuel as a Positive pressure and you are NOT relying on gravity.

Yep just call me Airtomotive man Stay tuned for the rest of the
amazing adventures of Airtomotive man Yeehaah. Leaping tall maybe small
airplanes and cars and some light trucks in a leaping bound. Faster than an
"el loco" motive.
Yes it is a high wing, thought I posted that info in first email I
think you may have snipped it. I am familiar with the need for a boost pump
for a low wing airplane and understand why (nothing liquid likes to flow
uphill without some help).
I will have left/right fuel valves but the capability to have both
tanks on at the same time similar to most Cessna's.
I have never flow a fuel injected engine, only carbed. But if I'm
understaning you correctly you are stating that "ALL" fuel injected
applications require a boost pump and a fuel primer. Regardless of high or
low wing. Is that correct ?
It sounds like you are knowledgeable about these installations so
let me ask one more question. What is the fuel pressure output required
for the boost pump ? I have surfed the net looking fo this info and have
come up nil. And do you fell that with the high wing configuration that a
lower end unit like a Facet 47860 which put's out 4-5 psi & 30 gph or the
Facet 480543 which put's out 6.5-7.5 psi & 45gph would be sufficient ? Is
6.5-7.5 psi too much pressure ?
All input appreciated.
Thanks Airtomotive man

YES, that is correct. It is a SAFETY thing.

let me ask one more question. What is the fuel pressure output required

come up nil. And do you fell that with the high wing configuration that a

There are some FAA requirements about fuel flow and fuel pressure.
Unfortunately they escape me right now. But for fuel flow unaided, the diameter
of the
fuel lines must be large enough to supply TWICE the fuel flow required by the
engine. The BOOST PUMP requirement must also support the flow rate and be
able to equal the pressure of the mechanical engine fuel pump.
There is NO PROBLEM if you use the higher pressure BOOST PUMP.
ALSO! I would HIGHLY recommend putting fuel filters (YES, TWO one in each
tank supply line) before the fuel selector which also means it is before the
BOOST PUMP. I just replaced TWO FACET Boost pumps tat failed because of derbies
in the fuel. The debris jammed the piston. But, good design of the Boost
Pump still let the fuel flow freely.
