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 spokesperson said, adding that "some of them suffered minor injuries during evacuation".
Aviation regulator DGCA and the airline itself have begun probing the incident, with preliminary information saying the smoke emanated from the left brake assembly of the aircraft's landing gear.
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.
