I believe this is the first time it's been in print. Just in time for
my final inspection.

To whom it may concern,
Murphy Aircraft Mfg. Ltd. approves a 5% gross weight increase for all
aircraft models manufactured by Murphy.
To reduce the elevator pitch sensitivity of the Elite it has been tested
and approved to reduce the width of the aerodynamic balances by a
maximum of 4 inches at each end of the elevator. This in effect will
reduce the total elevator span to not less than 102 inches.
The mass balance of the elevator must be maintained at not less than
75%.

Futher to our telephone conversation, please provide some kind of
written evidence confirming design agreement with as high a gross weight
as you feel comfortable with for this airplane on floats. I trust you
will be able to at least endorse the 5% increase for floats to 1890 lbs,
but anything more would be greatly appreciated. When you apply the
formulae in the CARS, in comes out to almost 2200 lbs, as I recollect.
That would be beautiful!
Also, something in writing confiming design agreement with the reduced
span spades on the elevator would be good to have on hand for my final
inspection. I did put in some doublers under the skins and on the tip
ribs to stiffen up the narrower spades, as this seemed prudent. There
are a couple of pictures on the wildcat BBS (www.dcsol.com).
