## Discrepancy

FOLLOWING ENGINE INSTALLATION A GROUND RUN WAS ABORTED WHEN AN ENGINE CHIP LIGHT ILLUMINATED IN A DIM FLICKERING MANNER ON THE CWP.  INVESTIGATION REVEALED THE DETECTOR END HAD BROKEN LOOSE BUT REMAINED ATTACHED BY ITS INTERNAL WIRING.  CLOSE EXAMINATION REVEALED THAT A PLASTIC CENTRAL POST HAD FAILED.  PERHAPS THE DETECTOR WAS DAMAGED DURING REMOVAL AND INSTALLATIONS.  SUGGEST A MORE ROBUST MATERIAL THAN PLASTIC BE USED TO MAKE PART HANDLED AS MUCH AS THESE ARE.  (K)
