## Discrepancy

WHEN LEFT AND RIGHT LANDING GEAR ARE RETRACTED, THE BRAKE ASSY, PN 30-143, MAKES HOLES IN THE UPPER WING SKIN HONEYCOMB, PN 572231-1.  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.
