Learjet 25 Wing Removal

Learjet 25 Wing Removal

(OP)
Hi all

Have been assigned to remove wings of a Learjet 25 for transport to an aero college, could anyone let me know what the job intales, an angle grinder is allowed but would rather not if I don't have to, also where I might find any relevant technical data sheets, SRM, AMM, etc

thanks in advance

RE: Learjet 25 Wing Removal

i'm pretty sre the Lear wing is built into the fuselage, not attached by just a few conections.  that said, the thing is put together ... how much disassembly (= time) vs being a bit free with a grinder ??  maybe cut the wings off, but 1st put on witness marks so you can align things properly again after transport.  maybe cut in a place where it's easy to add an external doubler, joiing both sides of the cut ?  maybe (just maybe) a bunch of internal doublers, which would look neater.  

if it's goin to a school, maybe they'd do the reassembly as a project ??

RE: Learjet 25 Wing Removal

I think there is a 12 year, 12,000 hour "de mate" inspection on these aircraft. It's a big deal, and puts alot of these loud bastards in the boneyard.

For some reason I have the idea that the wings are installed with a bunch of Tension bolts & "bathtub" fittings.

RE: Learjet 25 Wing Removal

Contact Bombardier-Lear service engineering, explain what You are doing and ask for advice. Emphasize, this jet will NOT fly again, and that a it will be used for maintenance training... so minimal disassy/transprot damage would be appreciated.
 
I assume they have dealt with disassy/transport of crash damaged aircraft, so this shoul NOT be a big deal.

Looks like the wing attach bolts are loaded in shear-

Senior moment, I suppose.....thinking about a falcon 10, maybe.

RE: Learjet 25 Wing Removal

Maybe you should try one of the aircraft maintenance forums or hook up with an A&P that has experience with Lears.  It may save you a personal injury.  There are definitely right and wrong ways to do anything.  

RE: Learjet 25 Wing Removal

Wings are challenging parts to get on the aircraft when it is being built. They would also be challenging to get off in a manner that keeps the aircraft an aircraft! Good luck with your challenge.
