Second Endeavor

We are still searching for our final format so we hope you enjoy these trails newsletter until be settle somewhere down the airway. As always, your comments and suggestions are welcome.

Cody

Our second national gathering is rapidly approaching and is scheduled for next month. The deadline for our block of rooms expires on May 25th. You can contact the hotel here: Click Here for Blair Hotels.

For those planning or thinking about attending here is the general schedule:
Wednesday: Arrival day, night party by the cabins.
Thursday: Morning brief by the Recreational Aviation Foundation RAF which is a volunteer group dedicated to preserving remote airstrips around the country. Lunch. Maintenance Seminars at the airport.
Friday: BBQ Lunch with Western Theme Costume Party that continues through the Night Rodeo
Saturday: Afternoon Group Discussions. Hotel Dinner (if enough folks) if not we invade a restaurant.
Sunday: Departures

We hope this has wet your appetite and that you will make plans to attend. The cost will be minimal for this event, just enough to cover the group meals and the rental van. Consider helping with your rental car for transport. Fees yet to be determined.

Membership

As of the end of April, we stand at 330 members. Not bad for a group not yet hitting the one-year mark! Although it is hard to be a free membership, we do several things to attract and reach new members.

Every month, Mark Matthews (Grumman Gang), send me a list of all the Grummans in the US that have changed hands. We take that list and and send them a letter telling them about ourselves, the advantages of membership, suppliers with the GPA discount, how to join ther Grumman Gang, and a link to Bondline. We also ask them to join.

This is how it came to be that we found the folks in the next story.

AMT School

Down in Bolton Mississippi, there is a community college, Hinds Community College. This establishment has an Aviation Maintenance Technology department which uses the John Bell Williams Airport to teach both pilots and mechanics.

The flight school bought a Cougar (GA7) and that is how we sent them a letter. A few weeks later I was contacted by one the AMT instructor to see about renting or buying the 2-seat rigging tools. I suggested he try Fletchair. I got an email a few days later that that was not going to work. I explained that I had lost a set and spent over a thousand dollars to replace it so I did not loan them anymore. I did agree to make paper tracing of all the rigging tools, photo them with rulers for reference, send tracing of the jack pad and other tools to the school for them to copy.

In return we picked up all the instructors and this crop of students as members. If I ever get back to my old stomping ground, I might just have to stop by and see the operation. It did give me a nice warm feeling knowing that these young mechanics in training are learning on a Yankee!

Maintenance tip (gear redo)

Right now I have a Tiger in my shop that the owner is getting ready to sell. Part of this process is a complete replacement of all main hardware, new glass, new interior plastic, upholstery, carpet, and windshield.

You can see a shot of the main gear in one of the forum posts. The original rim was bead blasted, primed and painted inside and out, new through bolts, nuts and washers to hold the rim. New brake disc, new tire, tube and all of the landing gear was disassembled , bead blasted, primed and put back together with all new hardware, adel clamps and a complete caliper rebuild.

The engine has about 200 hours since overhaul (all new components). The paint has been polished out so it will give the new owner a good solid plane while they decide on a paint scheme. The current owner plans on flying it out to Cody and then on to the Oregon to visit friends before flying it back to the Midwest for sale. That should shake any gremlins out of the engine and systems.

The American Aviation 2-seat variations have a very robust fuel tank setup. The fuel is actually carried in the aluminum spar (very safe place for it) so crash ruptures are quite rare. That with the visual sight fuel gauges make for a nice system with no electrical problems. However, I digress. Take the tank itself,…

It is not often that there is time or the will to completely reburbish the main landing gear down by the tires. First you have to take it all apart, remove the steel plates, remove the big bolts, drop the shims, remove the attach plate for the main fairing float plate, remove the spindle. Then…

A Cheetah with the normally horse powered engine came in and he was running Mogas in one tank and 100LL in the other. This is since we are near the time when winter fuel is in the tanks of the gas stations and we have a few warm days (it was 75 F here today),…

Yankee Firewall Extrusion Corrosion

Last year Ken had a Yankee that came into his shop with an interesting problem. The bonded extrusions that hold the engine mount has severe corrosion. So Ken did what Ken has done many times, figured out a repair for the customer and filmed the entire repair process. This DVD was then sent to me, Yankee Aviation, for digital mastering and conversion. We also tried to edit out all the mechanics bad words, but some will get by.

This video lived for 6 months at : http://www.yankee-aviation.com/docs/Yankee%20Extrusion.wmv
It is a big file, 636 M, plays for about 37 minutes, and uses a lot of my server space. I finally removed it to conserve on space but then received a call from a mechanic in Florida who had just this issue on a Yankee in his care. So the video was uploaded again for his use. Eventually it will move to a GPA server as part of the consolidation of information. Just another example of the Perks of the GPA.

Just remember the old saying;  “If you have to crash land, do it straight
ahead and try to only hit cheap things”

Just my thoughts for the day…… Ken Blackman
Air Mods N.W.

On the other subject, there is no minimum imposed at Air Mods N.W..  Small
orders are a problem for us, as with all small outfits (or large ones for
that matter).  The time it takes me to process an order (find the part, pack
it, do the invoice, run the credit card, etc.) makes it a losing proposition
as the average to accomplish this can easily hit a half hour.  Our shop rate
is $82.00, making that time worth 41 bucks and the profit on an O-ring may
be a few pennies at best.  If someone calls and orders one lo priced part, I
will do the  order and thank them for their business.  I chalk it up to
hoping they will deal with me when they need something else (of more value)
down the airways.  Much of the time the shipping costs is more than the
part(s) which costs the customer.  When I make an order from a supplier I
try to think ahead of any other products I may need from them and combine
the order to save me shipping costs and be kind their bottom line as well.

Even if I don’t have a minimum order, it is appreciated if it is more than a
couple of bucks.  The total really needs to be at least $25. Or more to make
it work out in our favor.  Never the less, I don’t do minimums because I
don’t appreciate it when it imposed on me although I understand.  Really,
what bites harder, is when a customer calls for advice on how to do a job,
sometimes asking me to talk their mechanic through it (who they’re probably
paying to talk to me) using parts they bought from Aircraft Spruce or
somewhere else.  This is where “consulting fees” can come into play.  Some
customers offer to, or insist on, being billed for this kind of service and
it is really appreciated.  It’s all in “consideration for the other guy”
that this concept falls into.  (BTW, how much free advice would you expect
from a lawyer or other professionals?)

Please don’t confuse the above with the time I (and many others) spend on
the Grumman Gang, AYA “Ask the Experts”, or the new GPA Forum.  This is time
I choose to spend, trying to help and protect people and airplanes.  Yes, it
is nice when this leads to sales and I do admit I get back something from
doing it that can’t be priced.  It all fits into the mix.
