## Discrepancy

BATTERY LEAKS FROM AROUND TOP SEALING JOINT BEHIND POSITIVE POST.  THIS IS THE THIRD HELICOPTER WITH CORROSION DAMAGE THAT WE HAVE FOUND CAUSED FROM A BATTERY OF THIS PN.  RECOMMEND BOTH BATTERY AND HELICOPTER MFG GET TOGETHER AND CORRECT THE PROBLEM.  THERE HAS BEEN OTHER REPORTS FROM OPERATORS OF THIS HAPPENING.
