helofixer Posted June 12, 2008 Report Share Posted June 12, 2008 Found some shear bearings in the head of our 407 separating. Changed all 4 bearings. Spent 2.5 days and 30 flights/ground runs to get the aircraft in track and balance. RADS gear constantly not seeing the blades, no matter what angle of the tracker , painting and repainting the blades. Night tracking is worse. Finally took all hub weight off, zeroed the tabs and set links to nominal setting and started from scratch. Took about 9 ground runs and 8 flights after that to get the ride close to spec and the crew ride to be ok. We have been using the RADS on our 206's and never really have problems. 407's is a nightmare every time, no matter which 407 we use it on (we own 2 and work on 2 other aircraft.) Anyone else have this much problem with the RADS? Do you use any other system? I know it takes time, and Ive been wrenching on 407's for 7 years and 206's for 14 years, but it seems half the time the corrections the box says to use do not produce results...ride gets worse and takes way too much time and effort to smooth the rotor. Any input? Quote Link to comment Share on other sites More sharing options...
