## Discrepancy

(CAN) PROP SYNCROPHASER TARGET CONTACTED THE SYNCROPHASER MONOPOLE DAMAGING THE MONOPOLE, MONOPOLE BRACKET AND PROP DE-ICE BRUSH BLOCK BRACKET. THE PROP DE-ICE BRUSH BLOCK BRACKET WAS BENT ENOUGH TO DISPLACE THE PROP DE-ICE BRUSHES ENOUGH TO SHORT ACROSS DE-ICE SLIP RING CAUSING PARALLEL PROTECTION BREAKERS TO POP.AS YOU CAN SEE WITH THE ILLUSTRATION PROVIDED THE WHOLE ASSEMBLY (PROP DEICE BRUSH BLOCK & PROP SYNCROPHASER PICKUP) IS SECURED TO (2) 'A' FLANGE BOLTS. THERE IS A SIGNIFICANT DISTANCE (ARM) THAT IS NOT SUPPORTED WHILE TRYING TO MAINTAIN TARGET TO MONOPOLE GAP (0.032 +/- 0.005).
