Read the full NTSB narrative

MAINTENANCE HAD JUST BEEN PERFORMED & THE CREW WERE BEGINNING A TEST FLT TO CHECK THE TRACKING OF THE MAIN ROTOR BLADES. WHILE THE PLT WAS HOVER TAXIING, HE LOST COLLECTIVE CONTROL & ROTOR RPM DECREASED. HOWEVER, HE WAS ABLE TO MAKE A ROLL-ON LANDING, BUT THE HELICOPTER ROLLED OVER & WAS DAMAGED. AN EXAM OF THE LOWER COLLECTIVE CENTER CONTROL HOUSING DISCLOSED THAT THE TERMINAL PIN WAS PLACED THRU THE OUTER HOUSING, BUT WAS INSTALLED BENEATH THE TERMINAL TEE RATHER THAN THRU THE TEE. THE MANUAL EMPHASIZES THAT THE PIN MUST PASS THRU THE TERMINAL TEE. THE MANUAL HAD NO PROVISIONS TO ASCERTAIN THAT THE PIN HAD BEEN INSTALLED THRU THE TERMINAL TEE.
