As the Airbus A-320 aircraft operating flight 6E-176 from Mumbai and carrying 148 passengers and six crew members landed at the IGI Airport around 1530 hours, the Air Traffic Control observed "dense smoke" coming out of the left-side lower portion and alerted the pilots, airport sources said.
The aircraft was moved to the taxiway where all passengers were evacuated through emergency slide-chutes, an airline spoksperson said, adding that "some of them suffered minor injuries during evacuation".
This is the second incident involving an IndiGo aircraft in the recent past.
On March 8, an Indigo plane from Delhi with 182 people on board had caught fire after landing at Kathmandu airport but no one was hurt. Then too, the fire was spotted on the plane's right brake assembly.
