Urgent - Speed brake DO NOT ARM light illuminates in flight

Postby Jeju » 06 Oct 2013, 17:16

Dear all,

I need your help urgently.

One of our -800 with winglets has a problem, " speed brake DO NOT ARM" light illuminates during flaps down for takeoff. This light remains on after takeoff and automatically extinguishs during cruise. Auto stow actuator and R897 relay were replaced but this snag is still alive.

Any clues would be welcomed!

Regards

Dear Dunny,

737NG-FTD-27-07006 is for SFP option-equipped A/C only.

We found the wires, W2737-006 & 002 at GD53 severed, and the snag is recified by crimping new terminals.

Remove the little triangle shaped cover thats over the speed brake arm switch.(3 screws)Bottom aft screw can be a PITA,might have to grind down an #2 apex tip then stick it in a racheting 1/4" dogbone.Anyway the wires to this switch or the switch itself may be the problem.Those wires are bent and stuffed into the cutout to fit under the speedbrake handle.Hope this helps,keep us posted!
