## Discrepancy

WHEN THE LEFT AND RIGHT MAIN LANDING GEAR ARE RETRACTED, THE CLEVELAND BRAKE ASSY (PN 30-143) MAKES HOLES IN THE UPPER WING SKIN HONEYCOMB (PN 5722311-1).  AT THE SAME TIME, THE BRAKE PISTONS ARE PUSHED INTO THE HOUSING ALLOWING ENOUGH SPACE FOR THE BRAKE PADS (PN 066-07300) TO FALL OUT IN-FLIGHT.  THESE BRAKES ARE INSTALLED ON THE CESSNA 441 UNDER STC NR SA644GL.
