## Discrepancy

HAVE BEEN EXPERIENCING PROBLEMS KEEPING THE M/R BLADES IN ACCEPTABLE TRACK AND BALANCE ON ALL 333/269D CONFIG A AIRCRAFT THAT WE MAINTAIN. ALSO HAVE BEEN FINDING MUCH MORE RAPID DETERIORATION OF THE M/R DAMPERS, FLAPPING HINGE BEARINGS, AND VERTICAL HINGE BEARINGS COMPARED TO THE PREVIOUS AIRCRAFT WITH THE P/N 269A1185-5 M/R BLADE ASSEMBLIES. THE NEW BLADES WITH THE EXTENDED NOSE SECTION WILL NOT STAY IN TRACK OR BALANCE FOR ANY ADEQUATE PERIOD OF TIME. SUGGEST THAT MFG DESIGN A NEW BLADE WITH A CONSTANT CHORD AND SOON.
