| Subject: | Re: Mandatory U.K. LAA permit directive. Shoot-Bolt stop |
If i may make some kind of input to this thread:
I was made aware of the impending issue by Andy Draper some two weeks before this
was issued by the LAA. At the time it was clear that the LAA were under the
cosh to do/issue something by the UK AAIB - so that has driven the nature of
the timing to a great extent. Its a UK jurisdiction thing of course and non-UK
Members Worldwide are not obligated to implement it - though why not take advantage
of the idea anyway?
Regarding the Club/LAA side of things, i did submit some suggestions at the time,
largely along the lines of couldn't a warning light operated by microswitches
behind the shoot-bolt have satisfied the AAIB's requirements (easy for me as
i have this on my aircraft). Along the lines of making ones own solution I
also suggested using the existing door handle shape as a 'mould' for a stop, could
the stop be RTV'd to the fuselage side to avoid drilling holes and asked
if there was any merit in fitting a stop for the front shoot bolt as well (concerned
about how the door would take being slammed shut onto the outside of the
stop when extended - as can happen out on the airfield if an open door on a
stationary aircraft were to be moved by a gust of wind). Andy did say he'd consider
these things and i think he has, but it was clear that by that time, the
LAA solution was well advanced and not really open to much further change.
So has there been a Club input - yes sort of [as above], but limited. Has Europa
Aircraft been involved - no idea, but i suspect not. Is it a good idea - in
my view it is, and i must confess that even with a large red 'Door Open' warning
light in the middle of my panel, i came close to missing that cue during
one pre-takeoff check as well (due to distraction - as ever). Will it actually
prevent someone from taking off with an unlatched door - i doubt it - but it
further reduces the risk and that has to be good for all of us.

PS: i understand the LAA-supplied Shoot-Bolt Stop parts kit is made using Stereo
Lithography which is a UV-cured resin process.
As such (and i did see one at my most recent visit (co-incidentally on the day
the MPD was issued), the finish is quite smooth and more geometrically accurate
method compared to that typical of the traditional 3D-printed melted fishing
line.
Being UV-cured, i'm hoping it will prove to be more resistant to UV degradation
than most plastics. Not sure the white resin used will suit everyone, but it
should be OK for painting. Time and the huge pool of experience evident on this
BB, will tell.
