737-800 speedbrake prob

Postby mephisto123 » 21 Jul 2007, 03:42

Hi there boys and girls, help if you can. Am new to the 737 and in the last 4 months have seen this prob on 4 diff aircraft. The prob is that the speed brake does not deploy in auto mode. Have changed actuator to no avail. Have carried out test per FIM all works satis, but aircraft keep returning with same prob. Anyone any ideas. Many thanks in advance

Same complaint on 4 different a/c ?, check if it's the same pilot everytime...
If you did the RTO test or iaw FIM, and lt works fine, you released the a/c again?
Did the problem re-occur everytime? Or just once on each aircraft?
Looks more like an operation or procedure fault.
If not then you have no luck and really have 4 problems on 4 different aircraft.
It could be the actuator (most probably) or the microswitch in the console (full with dust) . Is the armed lt coming on?
Let us know.
