Hi David.
Yes, I saw that, but it looks like as long as you stay out of class C & D airspace
and the area marked in black on the attached SUP, you should be OK. I'll try
and get through to SIA today in any case.

Carl, On the face of it going round to the west is no great problem even
if you cannot get a transit. Weather looks rather more of an issue!

I'm planning to head to the east so I can fly over Grenoble and through the Alps
(same as last year) so my son can experience the fantastic scenery.
The weather is looking a little more promising now, but it'll be raining when we
get back to the UK. Anyway, Thursday PM is decision time.

All,
I read with interest the article in Europa Flyer on the "G-OMIK" event. Last year
my Europa suffered a failure of an external support strut, in the hangar, while
the gear was retracted. It has been repaired, but there was some evidence
of a previous ground loop, or a high sideways stress landing, discovered. (i.e.
before I bought it) So I haven't got a crystal clear picture of the history.
Although, quite rightly, the failure mode is not speculated upon in the article,
I
can't quite see that any stresses were introduced to my bolts during my
incident, mainly due to the lack of forward speed. My thoughts are that when the
top of the tyre impacts the top of the tunnel, that induces a large longitudinal
force on the landing gear frame in the aft direction. (But just my thought).
During the repairs of my aircraft the landing frame has been subject to two
independent NDTs and
neither found any cracks.
So, I am thinking of replacing these bolts are a precaution. At the end of the
day they are a few quid to save a lot of money and effort in repairs.
Has anyone yet followed the advice laid out in Europa Flyer? And exchanged the
4 off 5/16" UNC x 2.25" Long bolts which hold the two LG03s in place? I'm asking
about experiences in completing the job - these are the question in my mind
at the moment: -
1) Is it a simple case of swapping the bolts?
- What I am asking is are there any special precautions to
take. Is this case of supporting the aircraft on blocks, then carefully
removing/replacing one bolt at a time, before finally setting the
torque correctly and wire locking.
2) Would it make more sense to do this job with the gear retracted?
- My thoughts here is that the bungee cord is at minimum
tension when retracted.
or 3) Is it better to remove and replace the bungee cord?
4) Are there any "gotchas" that have been experienced, when doing this
job?
Very best,
Jon

Sorry Jon I meant to get back to you a while ago but other matters in life
got in the way. Changing the bolts is quite straight forward and should
ideally be accomplished with the gear retracted and the weight off if
possible. Change one bolt at a time but do the final torqueing and wire
locking after all new bolts are in position. I am not aware if anyone has
taken my advice since I have no authority to mandate this action. It just
seems a wise (and cheap) precaution to take following any form of u/c
collapse after a ground looping incident.
Incidents in the hangar may be considered differently. The GOMIK incident
and other similar were NOT hangar incidents.
Pete
Ps I hope Wife and Kids OK and you may be getting a bit more sleep
now.................perhaps?

Hi Peter,
Thanks for the reply, don't worry about not getting back to the PM. I fully understand
what life can be like. Hope all is well with you back in Blighty. Things
my end are going OK. Albeit I have forgotten what sleep is, and have to feed
the twins every 2 to 3 hours. Janine is recovering well and should be back to
100% in the next 3 to 4 weeks. It was a bit of a traumatic arrival, but now
that all is well, I can say I had fun with the ambulance ride to the hospital
- it was scary at the time though.
I guess I should apologies to you too for jumping on the forum and not waiting
a bit longer for your reply; it's just with the change of family situation, I've
had my weekend pass (rightfully) revoked for the time being, and have an opportunity
to do this job, with Christoph (who helps/assists/double checks things
with me on my Europa) during the week, next week.
Thanks for the information on the bolt change, it sounds pretty straight forward
and I agree with what you say, a cheap and easy precautionary act, which should
save a lot of potential hassle in the long run. Plus more peace of mind in
cross wind landings, knowing things are newer and (hopefully) stronger there.
Best
Jon
