## Discrepancy

(CAN) DURING O/H OF MAAIN ROTOR HEAD, ONE OF THE BLADE BOLTS WAS FOUND TO BE CRACKED BY NON DESTRUCTIVE TESTING. BLADE BOLT P/N 206-101-152-1 CAN HAVE EIHTER NUTS (P/N 206-011-119-101 TORQUED TO 185-215 FT/LBS OR P/N 206-011-119-005 TORQUED TO 275-340 FT/LBS). THESE TWO NUTS ARE SIMILAR IN APPEARANCE & ITIS THOUGHT THAT THE BLADE BOLT CRACK MAY HAVE BEEN CAUSED BY INSTALLATION OF THE WRONG NUT AND TORQUE.
