What was found
AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT DIVERTED TO IAH DUE TO THE FLIGHT CREW REPORTING THAT IN CRUISE AT FL320 A FLIGHT ATTENDANT REPORTED A STRONG PUNGENT, ACRID SMELL IN THE AFT GALLEY, COMING FROM THE AIR VENT BY THE COFFEE MAKER. THE SMELL SPREAD THROUGH OUT THE AFT PART OF THE AIRCRAFT AND WHILE DOING SERVICE THEY NOTICED EVEN THE COFFEE THEY HAD BREWED SMELLED. THE PASSENGERS IN THE BACK OF THE AIRCRAFT COULD ALSO SMELL THE STRONG PUNGENT, ACRID ODOR. MAINTENANCE FOUND THE AFT GALLEY COFFEE MAKER #4 LEAKING ONTO THE HOT PLATE CAUSING THE ODOR.
