B737-200 Removal of the wings

Postby ivanvbm » 26 May 2012, 23:32

Dear Forum's Users,

I need to remove the wings of a B737-200. Then will be transported by ground in trucks, the fuselage and wings.
I would like to know if somebody has already carry out this job. I have experience in B737-200 maintenance
but this job is atypical, do not appears in any technical publication from Boeing.

Any idea is welcome!

Thank you for your attention.

Ivan B.

The wings are normaly never removed from the fuselage in the lifetime of the a/c.
They are shimmed and exactly positioned in Renton Seattle and bolted to the fuselagemidframe.
If you want to remove them you have to remove all attachment bolts (and sealant).
You may find these bolts and nuts under the wing/fuselage fairing underside wing and from the cabin under the floorpanels above the centertank.
I guess you are not planning to fly this a/c after removal/installation of the wings.......is it a museum item?

The wings are built into the fuselage structure. You wont removed them....

If you want them off, you'll have to cut them off.

Thank you for your reply. The airplane will not fly anymore, is to make a restaurant inside. The option to cut-off and then in the site (after travel), to attach the wings with splices or welding, could be the "easy" form because the airplane have 4 years on ground. But is not decided yet. Regards.

well, its an old post but I''ve done that job many times and don't think cutting is the best way. It's not too hard to remove in one piece, you will need ground assistnace to hold the wing of course because you have to remove the landing gear first.
The wing job is easy, it takes some time but you can do it without problem.
speaking of the bolts (after you remove the fairings and disconnected all the things attached to the wings): clean the prc of the main bolts and nuts and lossen them (3m brusch products, rpm chemical, or just an old piece of saw and a little of patience), break the nuts of the secondary bolts (there are some details in this particular job but its not complicated). once you have the wing supported by any kind of external assistance you remove the main bolts and it goes easily out.
some tips include make bigger holes inside the wing and fuselage tanks to make more confortable the job.

I am part of a team who wish to take the wings off a B737-200 to move it from an airport to a reserve by truck, it will be put on display and obviously never fly again. I am a heavily experienced B737-200/300/400/500 line and heavy maintenance LAE, but have never needed to remove a wing as it is not required.
Apart from the main wing to centre section bolts (within the centre and wing tanks), I remember there being countless hi-lock fasteners through the laminated lower wing skins. I cannot remember the upper skin fastening. Which i imagine will require removal too?
There is no information within the MM, but I believe there may be information within the recovery manual, anyone have a copy?
Can someone with the experience in wing removal give some more information regarding the upper and lower skin or other attachments of the wing to the centre section.
Would prefer to remove the wing, minus engines, flaps and MLG without destructing the wing by cutting.
Any help much appreciated

Its not impossible to do.
