Graham,
Sorry but my previous email went prematurely for some unknown reason.
I shall try again .........
The little auxiliary latches you refer to on Mal's plane do not guarantee th
e proper engagement of the rear shoot bolts. I have had several instances w
here the rear shoot bolt has not engaged properly but so far it has been qui
te obvious at the time. I find the doors are somewhat temperamental to tem
perature and how long they have been left open. Most of the time they shut q
uite easily but sometimes they are the pits to shut from the inside and the l
ittle latches have no affect in respect of either.
Cheers mate

The idea of a hinge designed to fail first after a door opening in flight incident
is interesting. Best to prevent the door opening in the first place?
The C150 Aerobat and other planes have doors that can be jettisoned deliberately
to aid egress in the event of an inflight incident (like the wings folding maybe).
This idea seems sound as it is in keeping with the regs for the category
of aircraft.
For those who wish to add structurally inefficient kgs to the weight of their aircraft
then reinforcing the doors may be a route they wish to take. But where
does this process end? Double harnesses in case one fails? Spare set of wings!
If the number of unintended canopy/door incidents is sufficient the LAA will no
doubt take a view and introduce a fix via an MPD. Personally l think the incidents
recorded appear to be low in comparison to the total fleet flights. Perhaps
we can get this info from MM at the LAA?

This is a very interesting video. It shows how, even with locking washers,
bolts and nuts simply back-off under vibration. But it stops there. No help
about what to do to prevent this problem. More research, I guess.

I couldn't help smiling while reading this.
I am involved with the restoration of a Jaguar XK120 and a few months
back, visited an ex Jaguar racing mechanic (well past retirement age) at
his immaculate workshop while searching for obscure bits. During a very
interesting discussion, he explained that years ago, Jags were plagued
with problems with the bell housing bolts backing out during endurance
races. The solution, discovered by trial and error, was to replace the
helical spring washer with plain washers.
These old timers know a thing or two!

| Subject: | Glider Wings for Sale |
Hi All,
Regretfully, my motorglider wings are not very compatible with the short,
rough airstrip that I recently moved to. A pity, really, since I was looking
forward to soaring amid all the wonderful vertical development seen daily
in mid Georgia!
Remember, in the US, no medical is required to fly VFR, day or night, or IFR
in a motorglider. Unlike LSA regulations, even a failed medical is not an
impediment to flying a "Glider, Self-Launch".
The wings are located at Custom Flight Creations in Seffner, FL.
http://customflightcreations.com/
A brand new pair of Johnny's custom WingWalkers is also available for easy
rig/derigging of the wings.
If interested, contact Bud Yerly at Custom Flight.
