Hangar Flying

Marc Zeitlin has just posted a long history of Emag/Pmag
experiences.   The following is the "bottom line".


Recommendations:

My recommendations, based on my opinions and my examination of MANY Emagair unit disassemblies are these:

1) If you are flying with a version 113 or 114 product from Emagair,
ground your plane immediately and remove the units.  Do NOT fly with them, or with the "fix" described in the SB.  It will work for a
while, but for how long?

2) If you have a unit that you have purchased but haven't used yet, return it for a refund - do NOT put it on your aircraft and fly it.

3) If you were considering Emagair products for your engine, consider something else - do NOT purchase one and put in on your aircraft.

When Emagair have hired a competent mechanical engineering firm to redesign their systems, have FULLY tested the units under O-360 type vibration loads for thousands of hours, and publicly published the results, THEN in may be appropriate to consider these units.  Until then, it is not.


If Mr. Cotner, Mr. Read, and my experiences with these units put
Emagair out of business, and it costs some of you the opportunity to get a refund on your units, I'm sorry for that, but Mr. Cotner was
lucky, and relying on luck to keep people alive is not acceptable.


Everything that I have written here is either my personal experience, my opinion, or my recommendation based on my opinion.


I know that many of you are saying (to yourselves or to others) "I
told you so", and you're right - you told me so, but my desire for
Emagair to succeed overrode what should have been enough evidence to the contrary.  Feel free to write me with "I told you so" messages, if it makes you feel better.

I'm happy to address any issues, comments, or questions that anyone may have.  Since Emagair never responded to my entreaties to sign an non-disclosure agreement with them, I do not have any responsibility not to explain the inner workings of the units or the problems therein.

PLEASE, PLEASE, PLEASE - distribute these messages (and Mr. Cotner's and Mr. Read's) to any and all aviation related mailing lists, fora, and printed newsletters.

The NWEAA is next week.   If you plan to be there please read the
following:

I can furnish some refrigerator space, shelter in case of rain,
and friendly conversation.   Unfortunately I am tied up most of the
day each day but see me when I drop by the canard parking area.

Candy and I will be there in our Dolphin motorhome (license is
Washington 308 VWB (Very Wide B*stard)   We get pretty choice
parking close to the front of camper parking.   Not hard to find.    
3 rows from the flight line and 5 or 6 campers from the forum tents.
Please do not let our 2 cats out if we take them.

The door is left unlocked and there is a propane-run refrigerator
inside.    Put whatever you want in the refrigerator.   If it is
beer I will drink it (just kidding, I will bring a bunch and I expect
you to drink mine ( I don't have a weight limit on the motorhome and you
DO on the airplane)).

I will also try to remember to bring a bunch of folding chairs.
I will leave one or two by your airplane IF THE RULES ALLOW IT.
I'll collect them on the last day.   (we stay until EVERYONE else
has gone).

If it RAINS (common in western WA but it seems unlikely this year)
I can seat 7 or 8 (depending on how friendly you are)(grin) in dry
comfort.   We have a restroom inside but no shower.    Also have a
variety of reading material and survival rations.   At least 3 could
sleep inside.

I will not be around a whole lot because my wife and I
are volunteers judging antique certificated airplanes.   We get
pretty busy when people are arriving.    Please come by the
motorhome someday after 5, if you can.    Candy has a lot of
true BS stories (Candy's 1st PIC flight is a classic)
(her intentional groundloop is just as good)
(and flying in an aluminum shadow).
I have a few, too.

To: All canard-pusher pilots and builders:

My wife, Candy, and I are legal residents of Maui, Hawaii but we are
usually in WA state so we can travel in the 48 states near here.  

We own 2 houses on Maui and once a year we have to go there for our
annual medical exams (we have only emergency coverage in the other 49
states). We could live there but we could not go to NWEAA, OSH, RAR, and  the rental money is nice.  

We go to Maui when a house is empty.   One is empty now.    

Friday (9/29) we will get there.

After a week or so to repair cabinet doors, window screens, etc.
we would be happy to host any 1, 2 or 3 of you that would like to
come over for a week or so (NO shorter - there is too much to do). We
usually go to Hana, snorkeling, whale-watching, etc.

Cost to you:
(1) a rent-a-car for a week (our car is pretty old, don't need to put
    more miles on it),
(2) whatever you want to spend on food (we share the cost),
(3) whatever you want to spend on cruises (may be a little early for
    whale watching but there are shorkeling cruises to Molokini, Lanai)
(4) you might like to rent a C-172 for an hour or so to see Maui
(5) other minor stuff.

Absolutely the cheapest week on Maui you will ever see.   Eventually I
will live there and I will charge for this.

We like to go a lot - beach snorkeling is free, trip to Hana is
nearly free, trip to the top of Haleakala is free, square-dancing
is free, lying on the "clothing-optional beach" is free, etc.

We drink a little beer or wine.   Tell lots of stories (Candy's
or better - I just listen).   We can sit in the hot-tub (indoors)

We are busy with family (on Kauai) stuff after Nov 22 so come earlier.
Got to get the house rented around Nov 15-22.

Would someone please put this email on the Cozy, Berkut, Aerocanard,
Velocity, and/or Eracer sites?   Thanks.

Let me know by calling 808-250-0939 or bruce@ywave.com

Hi Group

I had a recommendation/requirement from my technical advisor to
do some rewiring of the Longeze project.   I am in the middle of that.

I will have most of PIDG terminals and ring terminals replaced
in the next day or 2.   Now I am wondering what should be on
the "Essential Bus".   It is not too late to make changes, on
your recommendations.

I have 7 circuits on appropriate sizes circuit breakers.   All of the larger
stuff, generally.   On circuit breakers: Strobes, Nav lights, landing
lights, electronic ignition, alternator field, alternator output, and
the "essential bus".

Everything else is on fuses.

The Essential bus presently is the following:

1. Radio
2. Transponder
3. Intercom
4. Altitude encoder
5. CHT/EGT (all 4 of each) gauge
6. Fuel pump

All 6 of those essential circuits are on individual fuses PLUS the circuit
breaker for the essential bus.

There are 11 other circuits which are on fuses, only.   EVERYTHING
operates off the Master solenoid, of course.

I am wondering if ANYTHING ELSE should be on the "essential bus".

I will appreciate all comments.

Thank you very much.

The RAF manual requires thin aluminum shields
at the end of the wings to protect the wings from
engine heat.   However some builders have gone to
stainless steel.   I am at the point of needing to
order the steel.  

ASC lists 304 stainless, .018 inch thick.  
I assume that that size will be OK

A piece 12" X 48" could be cut in half for
shipping and should be large enough to do the
job, I think.

ASC also lists 302/304, Ann. at 035 inches thick.
Would that thickness be required?  The aluminum
specified in the RAF manual is thinner than that.
What is the Ann.?   Annealed?   Necessary?

Thank you for any comments.
