## Discrepancy

THIS BOX ASSY IS A NEW STYLE USING RUBBER GROMMETS INSTEAD OF BUSHINGS ON THE FLAPPER VALVE AND HAS A SPLIT SHAFT THAT HOLDS THE FLAPPER DOOR.  THIS DOOR IS JUST SANDWICHED IN THE SLOT WITH NO SCREWS TO SECURE IT TO THE SHAFT.  THE VIBRATION WORE THE DOOR INTO 2 SEPARATE PARTS CAUSING THE FLAPPER TO CHOKE OFF THE FORWARD SERVO AND CAUSED COMPLETE ENGINES FAILUE.
