The German Federal Bureau of Aircraft Accident Investigation (BFU), will not be probing the incident, where a tow-truck fire damaged a Lufthansa A340-300 at Frankfurt airport on Monday 11 June.
Bundesstelle für Flugunfalluntersuchung, BFU, will not probe the incident because the aircraft was not engaged in any air transport operation at the time, but will record the incident.
Lufthansa confirms, the tow-tractor that caught fire was a diesel-powered vehicle, and operated by ground-handling firm Lufthansa LEOS,a subsidiary of Lufthansa Technik.
Lufthansa LEOS has recently added a second electric ‘eTug’ tractor powered by lithium battery, to its ground-handling operation at Frankfurt airport.
The eTugs, are developed by Sweden’s Kalmar Motor capable of towing Airbus A380 and Boeing 747 and is designed to cut emissions by 75% compared with a conventional tractor.
