Message for those attempting Mod 74, and things they dont tell you.
Perhaps others have found this easy, mine was quite tricky..
You are going to have to spend many hours hanging like a monkey in the
baggage bay, in a confined space, wondering which hand to use to
drill/turn nuts etc... unless you are 18 years old and supple, your
muscles and joints will ache. In this confined space, you will have to
precision drill through interlocking spring steel fittings, eg through
tie bar/W35 end fittings, and W34 plates. Ordinary drill bits will not
suffice, and on occasion everything had to come out for finishing with a
pillar drill..
The holes are close against the rear of the cockpit module, where
ordinary electric drills have no space for a vertical alignment. If you
try with an ordinary electric drill - unless it has a 45 or 90 degree
end fitting (= very costly type of drill) - you will fail and make a
mess of parts like I did. Equals long delay and cost as you order new
parts through DHL (I am based in Kenya with Europa 5Y-LRY).
I did my work in a maintenance/repair hangar in Nairobi facility for
Cessna Citations and Beech King Airs, so no shortage of tools/expertise.
But still this was challenging. I used a pneumatic 45 degree drill,
with cobalt bit, and eventually got things straight. But the message
is.. dont rush, get the right tools, or you will find it impossible to
do this mod correctly... some 42 separate holes have to line up
precisely. You will need a 45 or 90 degree angled drill, which is not a
common tool.
Afterwards you may need some physiotherapy.
Regards to all.
