What happened
On 31 December 2016, an Airbus A319-111, registration G-EZMH, was conducting a commercial passenger flight when the crew noted unusual conditions in the cabin. Approximately 20 minutes before the descent into London Gatwick Airport began, the crew reported excessive heat on the left side of the rear galley, though no specific source was immediately apparent.
As the aircraft approached within ten miles of the threshold for Runway 26R, cabin crew members reported the presence of smoke, described as having a strong, sweet, hot, and dusty electrical odor. In response, the flight crew issued a PAN-PAN call to Air Traffic Control, notifying controllers of their intention to halt on a taxiway after landing to investigate the situation. The Airport Fire Service was requested to attend as a precautionary measure.
Following the completion of the 'Smoke/Fumes' Quick Reference Handbook (QRH) checklists, the aircraft landed without incident and came to a stop on Taxiway J. While the Airport Fire Service inspected the aircraft's exterior and later boarded the plane to examine the rear galley, they were unable to locate any source of heat or the reported smell.
The investigation
Investigators examined the aircraft and the circumstances surrounding the reported smoke. During subsequent maintenance inspections, the investigation identified an inoperative beverage maker located in the rear galley. This component was replaced, and the aircraft returned to service without further issues.
