Outboard flap tracks (1-2-7-8) fwd fitting must have play 737-3/4/500

During inspections it appears that the fwd attach fitting of the outboard flaptracks (No. 1-2-7-8) are frequently declared unserviceable due to play. This play MUST be there and is even with new installed bushings a minimum of 0.018 “up to maximum 0.021”.  During an inspection the play can be as much as 0.029″ max. which is 0.74 mm! And therefore the flaptrack can “rattle” on the front: No panic!  See the limits in AMM 27-51-49 page 603 and 604 and figure below item 6 (bushing/bushing).
