I’m revitalizing a 320
completed in 1991. I again downloaded all the SBs but seem to remember some
items (heard over the years) that are not there. Maybe they were only
concerns and are not serious enough for SBs.
1)
Is there an
inspection method to determine if the SB (009-92) for the early nose gear has
been complied with (SN 1-461)? The inspection method I’m referring to does not
(should not) include teardown.
Jim,
Don't know. If Lancair did the mod I think
they put an "A" after the serial # on the bottom of the flange. If
the centering mod was done, I think the flange was changed. Isn't this
noted in the aircraft log? Maybe Lancair would have a record if the prior
owner had the strut serviced there.
2)
The plans
call out bolts holding the nose gear strut to the fork to be AN4-X … The nut
is a big thick fiber insert nut. The called out bolts on the fork hardly reach
the fiber. Are thinner nuts appropriate here? Are castle nuts
applicable/acceptable here?
No. Finally a bolt used in both shear and
tension. Get a longer bolt and use a std sized lock nut. (bolt inserted
from the bottom,nut up top).
3)
Does the
main gear hydraulic cylinder rebuild kit only provide O-rings and gaskets and
the like? Or is there a way to replace or refinish the “rod” … as this one is
rusted. Can I buy just the rod or do I need to purchase a new
cylinder?
Buy a new cyl.
4)
I would
like to replace the outboard half of GM3 … the over center linkage with the
updated longer version. Don’t see it on the Lancair “parts” website. If the
newer longer GM3 is not available, and I have to use the original part, is it
suitable for use with the “new” over-center torsion
spring?
Call Lancair. The problem with the old style
was poor drilling of the link by the builder followed by failure of the rod
end/link.
5)
Can
sequence valves be reworked? Is there an overhaul
kit?
Yes. Yes. I would but a new one if
there was a possibility of the installed one having been abused.
On another subject … I
am going to begin baffling work on my new Lancair (360) in the not too distant
future and see in the plans they call out to “use the blueprints for cutting
and folding the aluminum” … page 21-33 of the fast build kit plans manual. I
have no such blueprints and the list of blueprints supplied with the kit has
no mention of such plans. Am I missing something I should have gotten from
Lancair originally or do I need to purchase baffling plans separately? Or
what?
Check with Lancair as they might have copies
available.
