What was found
DURING PREFLIGHT, SMALL PARTICLES WERE FOUND WHILE CHECKING THE FUEL SUMPS. ON FURTHER INVESTIGATION, IT WAS DETERMINED THAT THE EC776 SLOSHING COMPOUND INSTALLED BY THE FACTORY WAS SEPARATING FROM THE TANK. WE WERE ABLE TO REMOVE SOME PIECES THE SIZE OF A QUARTER. THERE IS STILL VERY LARGE PIECES OF LOOSE SLOSHING COMPOUND IN THE TANK THAT COULD EASILY OBSTRUCT THE FUEL SCREEN WITHIN THE FUEL TANK.
