March Meeting
The March meeting, held on the 11th, was
well attended by chapter members and even a
smattering of "significant others." Prez Johnny
Murphy shouted the rabble to order shortly after
7:30.
Tony Yacono was first up, with a discussion
of Young Eagles. Tony hopes that local pilots 200+
Young Eagles the next time we have a Young
Eagles Day. During the last Young Eagles Day,
local pilots used fifteen aircraft to fly more than 135
Young Eagles before bad weather shut down the
operation. A few additional kids were flown
several days later.
Next, Bill McClintock discussed the tractor
people-moving operation at Sun 'n Fun. If you
haven't been to Sun 'n Fun, tractors are used to pull
flat bed trailers, outfitted with chairs, around the
Sun 'n Fun site. Chapter 724 has supported this for
the past few years with both drivers and tractors.
Ted Yon is taking over coordination of the effort for
the chapter. If you are interested in volunteering the
use of a tractor or your driving services, contact Ted
in the near future.
Incidentally, if you are flying to Sun 'n Fun,
Merritt Island Air Service has a copy of the arrival
and departure instructions available at the desk. In
addition, those of you who have computers can find
the instructions on the internet at:
http://www.sun-n-fun.org/
Irv Bubeck gave a short, humorous account
of the problems he had getting an aircraft he built
up from Aeronca parts certified by the FAA. The
process became so convoluted that the airplane
ended up being called an "Aeronca Irv"!
Johnny gave a brief presentation on the
Lancair 360 "Big Tail" beef-up designed and
recommended by Martin Hollman. Independent of
Lancair, Hollman did a finite element analysis of
the Lancair 360 and determined that the design had
the potential for catastrophic tail flutter at speeds
over 142 kn . The problem does not exist with the
original Lancair tail. If you want a copy of the
article, which gives instructions for the simple beefup Hollman recommends, ask Ted Yon or Fred
Mahan, or get it directly on the internet at:

Pat Salamone has flown off the restrictions
on his beautiful red GP-4. He presently is touching
up the paint and taking care of some minor
problems. If you haven't seen it yet, see Pat's
4
airplane on the north side of the runway, it's a real
head-turner.
Also reported was that Chuck Downing has
his Glasair III flying. Between them, Chuck and
Johnny have built a whole squadron of Glasairs!

Golf Ball Dimples On Propellers!
If you missed the story in the January 1998
Sport Aviation, page 77, you should go back and
read it. The title is "More Speed With less $$" by
Anthony (Tony) C. Occhipinti. Tony's brother-inlaw, Bill Cobb, lives in Eau Gallie, and if
everything works out Bill will be at this meeting
with information on Tony's dimple tape. It should
be very interesting.

Special Airworthiness Bulletin
On February 13, the FAA issued a Special
Airworthiness Information Bulletin. A helicopter
with a variant of the Lycoming O-360 failed in
Tampa last summer because of an oil leak. The
cause was traced to re-use of 1/4" star washers.
" 'Star washers' can be crushed under normal
torquing pressures (90 in. lb.), thereby rendering the
locking washers ineffective. The lock washers are
designed to have a deflected spring action with
hardened cutting edges which aids in fastener
retention. These spring washer tabs are displaced
under normal torquing pressures and lose their
locking capability after first use. In addition, the
loss of retention after the first use is also aided by
high engine temperature cycling.
Lock washers should not be reused at
overhaul or any time they are removed. AC 6512A, Chapter 10 - Engine Maintenance and
Operation (General Overhaul Procedures), states
that all safety devices should be disposed of when
they are removed."
So, a word to the wise. Don't reuse star
washers or other safety fasteners.

Flight Physicals And Your Drivers License
By Ben Owen, Technical Counselor News,
Fall 1997
When you apply for an aviation medical,
you sign an agreement that enables the FAA to
check your driving record through the National
Driver Register. If you would like to do this
beforehand to see what records are there, you can
contact the National Driver Registry, 400 7th Street,
SW, Room 6124, Washington, D.C. 20590. You
need to send them your full, legal name, date of
birth, sex, weight, height, color of hair and eyes,
and your drivers license number (the letter must be
notarized to be acceptable to prevent just anyone
from checking the registry). Providing them with
your Social Security number is optional.
I checked mine, sending it in on December
16th, and received a reply on January 16th. If you
have any doubts on what is on your drivers license
record, you can check with them and with your state
drivers license officials.

Major Breakthrough in Use of Patterns!
Russ Erb, Chapter 1000 Newsletter, 11-96
Many of the parts on our aircraft are defined
not by dimensions but by full size patterns. This
generally includes any shape that does not consist
solely of rectangles and triangles. I have found that
using a graph paper overlay and CADD software, I
can redraw these pieces, print them out at full scale,
and thus have an expendable pattern without cutting
up my plans.
The problem always seemed to be how to
attach the pattern to the work piece. Various
methods using tape have been used with varying
degrees of success. I tried Rubber Cement to glue
my patterns to my wing rib forming block, which
worked reasonably well, except that the pattern was
not easily removable. In fact, half of it is
permanently attached. While this is fine for tooling,
it would never do for actual parts.
Sticky pads (Post-It  Notes) had always
intrigued me, and it seemed it would be nice to be
able to apply the adhesive to a pattern and stick it to
the part long enough to cut out the part, then peel
off the pattern. While at Staples doing some
undercover research for Project Police publications,
I came across the Avery (not the tool company)
Removable Glue Stic. It's just like a glue stick, only
not quite as sticky. It's like the stuff on sticky pads.

I tried it, and it seems to hold paper to aluminum
and wood acceptably. I haven't tried it on any other
materials. It works great, and, best of all, it's cheap!
If you happen to get a little too much on the paper
and some of the adhesive transfers to the aluminum,
it will wash off with water.
