POSSIBLY RELATED TO POP SOUND AT 5,000FT ON APPROACH THAT SOUNDED LIKE FLIGHT ATTENDANT DROPPING SOMETHING IN THE BACK BUT THEY DID NOT. FOLLOWED BY SLIGHT BRIEF ACRID ODOR. MAINTENANCE FOUND THE LEFT PACK WATER EXTRACTOR 10HM8 COUPLING SLEEVE DETACHED AT THE DUCT CONNECTION POINT TO THE REHEATER WITH BROKEN COUPLING RETENSION CABLES.
