## Discrepancy

EXHAUST PORT OF DRY AIR PUMP FELL OFF DURING FLIGHT AND LODGED IN LANDING GEAR RETRACTION SYSTEM.  AC HAD TO LAND NOSE GEAR UP.  PIPE THREADS IN ALUMINUM PUMP HOUSING WERE WORN AND CORRODED.  SUGGESTED THAT FITTINGS BE INSPECTED FOR SECURITY MORE FREQ THAN 100 HOUR/ANNUAL.  ALSO INDUSTRY SHOULD ALLOW PIPE DOPE COMPOUND ON EXHAUST FITTINGS SINCE INGESTION OF FOD WOULD NOT BE A FACTOR ON THE EXIT PORT. (K)
