A fire broke out in Auxiliary Power Unit (APU) of an engine of Air India Delhi-San Francisco flight ( Boeing 777) at Delhi’s Indira Gandhi International Airport on Wednesday, according to ANI. The incident happened while the AC repair work was underway.
Airport personnel observed black fumes from the APU exhaust and, believing it to be a fire hazard, sprayed APU and part of the fuselage with foam spray, the national carrier said.
However, the airlines termed it as a minor incident. The aircraft was empty at the time of the repair work and the fire was doused immediately.
The APU is the smallest engine on an aircraft and situated at the tail of it. It provides the necessary power to start the main engines.
Recently, Air India had approached State Bank of India to lease five Boeing 777 planes owned by Jet Airways, but 19 of its own aircraft, including four 777s, have been grounded for months due to lack of funds. Air India has 18 Boeing 777 aircraft, 27 Boeing 787s and four Boeing 747s in its fleet.
