Subject: | Re: Daily Mail report of father and daughter fatality |
Just had a look at one of the BBC reports on the accident.
http://www.bbc.co.uk/news/uk-england-leicestershire-23816203
The crash occurred in the field adjacent to the airstrip. From the footage
looks as though the aircraft was travelling towards the strip suggesting
they were about to land.
The wreckage shows the aircraft essentially upright when it impacted and the
wings are still attached to the cockpit module. One shot shows the gearbox
with a complete undamaged propeller blade though this appears to have
sheared from the crankcase housing. I'm not familiar with aircraft crashes
but would have expected the prop to have been turning on impact (but maybe
was stopped - either before or on impact).
Pure guess but I wonder if the engine stopped on finals and then an extended
glide was attempted - leading to a stall.
Hopefully the AIB will put our minds at rest soon although they have told
the BBC that it could take six months.
Structural/ component failure seems unlikely though if it was we may hear
pretty soon (from the LAA). Many of us will recall the aftermath of William
Mills tragic accident.

I would go for stall or spin, but I understand he was a pilot with a
reasonable amount of hours on type, and they always go for pilot error, so
its only guess work from me, and structural failure meaning loss of control
through some component failing, not the wings breaking off or tail plane.
I hope the investigators find the right cause of this crash,
Alan

Hi Carl.
Thanks for the video I had not seen it before.
All you comment seem pretty reasonable to me, well done.
Hope we get the answer quickly and no major mod required.
Alan

Subject: | Re: tailwheel arm fitting |
Rowland,
It just doesn't fit without tweaking.
You will find that it may be necessary to file a small round in the skin
to clear the tail spring. Also the 7/8 inch hole is probably drilled
perfectly square yet the spring does not go through the tailpost
perfectly square and it is shown in the diagram in the manual page 23M-8
that it is angled through the tail post and impacts the lower skin. So
some adjustments are normal. Remember a small amount of space is
necessary for the Redux when it is all done and ready to go final.
You will also see that the XTW15 flat piece of metal for the 5/16 bolt
doesn't quite line up right, and some adjustments there are not uncommon
also.
Not speaking for the factory any longer, I can say what I do, and in the
case of the tail spring, I find the ply support pylon in the tail is
usually not tough enough for a couple ground loops, so I tend to build
the pylon all the way across the fuselage bottom as shown in Fig 11
Chapter 23M but make it just a bit wider. I do this so when the client
drills the hole for the AN5-12 bolt and finds he can't quite get the
alignment perfect, I come back in and install a 3/8 steel tube in the
bottom as a sleeve with Redux. What the sleeve is good for is it helps
when the bolt is pulled up. The sleeve prevents the bolt from crushing
the fuselage skin, and ply support when the bolt is properly tensioned,
it also gives more support for the bolt, retards bending of the bolt and
it will be less likely to be difficult to pull out the bolt, if the
spring is bent in a mishap...
Happy building,
Bud

<rowlandcarson@gmail.com<mailto:rowlandcarson@gmail.com>>
I've drilled the 7/8" hole in F10 for the tailwheel arm. I used
outside calipers to get the centre the correct 1" above the fuselage
bottom skin (that is, the OUTSIDE of the fuselage) and took care to keep
the bore of the hole parallel to the fuselage bottom. The bottom of the
hole finished up just clear of the curved bottom flange of F10.
The tailwheel arm XTW06 fits into the hole, but will not go far enough
forward for the hole at forward extremity of XTW06 to align with the
marked centre 160mm forward of the front face of F10, because XTW06
binds against the bottom of F10 & of the fuselage.
Do I need to
(a) enlarge the hole in F10 upwards?
(b) relieve F10 & fuselage at the bottom centre to clear XTW06?
Opinions, please!
in friendship
Rowland

Hi Roland, I had to open up the 7/8" hole (on center) as well as relieve
the bottom of the fuselage (rudder closeout) to accommodate the tailwhe
el arm. Regards,ErichN28ET Classic Mono 914
