A Lufthansa Airbus A340-300, registration D-AIGV performing flight LH-489 (dep Jun 23rd) from San Jose,CA (USA) to Frankfurt/Main (Germany), was enroute over the Atlantic Ocean in Canadian Airspace, when a powerbank in the cabin of the aircraft suffered a thermal runaway and caught fire. Cabin crew quickly extinguished the flames and cooled the device down before securing it in a safe container. The aircraft continued the flight to destination for a safe landing without further incidents.

On Jul 24th 2018 the Canadian TSB reported Germany’s BFU notified the TSB of the occurrence, the BFU have retrieved the power bank.

On Dec 19th 2018 the BFU released their June Bulletin (usually due mid August) briefly stating the occurrence is being investigated by the BFU. After about 4 hours enroute an accessory battery stored in a passenger’s rucksack inflamed emitting lots of smoke. The cockpit crew donned their oxygen masks, cabin crew used halon fire extinguishers, put the fire out, cooled the battery down and kept it under surveillance for the remainder of the flight. About 30 minutes later the flight crew removed their oxygen masks and continued the flight to destination. Two passengers were treated for shock after landing in Frankfurt.
