## Discrepancy

MAIN ROTOR BONDING STRAP BROKEN.  THIS IS A CONSTANT PROBLEM, PORTION OF THE STRAP WHICH CONTINUES TO BREAK IS MADE OF COPPER.  THIS END OF THE STRAP BOLTS TO A STAINLESS STEEL CONNECTION WHICH NEVER BREAKS.  THE ENDS OF THE BONDING STRAPS SHOULD BE MADE OF A STAINLESS STEEL MATERIAL OR SOMETHING MORE RELIABLE THAN A COPPER FITTING.
