The Aircraft Accident Incident Bureau (AAIB) will be summoning pilots of three international flights that narrowly escaped mid-air collision in the Delhi flight information region, sources in AAIB said on Friday.
The collisions between the three airlines - Dutch carrier KLM, Taiwan's Eva Air, and US-based National Airlines were averted on December 23 following multiple auto-generated warnings by the Air Traffic Control (ATC).
The three foreign airlines were flying almost at the same level which is a clear violation of mandatory separation. The US National Airlines from Afghanistan to Hong Kong was flying at 31,000 feet, the Amsterdam-Bangkok EVA Air plane at 32,000 feet and Vienna-bound Dutch KLM at 33,000 feet.
As per the Directorate General of Civil Aviation's (DDGA) Aircraft (Investigation of Accidents and Incidents) Rules 2017, the AAIB is empowered to summon the pilots of foreign airlines for investigation.
These rules "extend to the whole of India and apply to, and to the persons on, aircraft registered outside India," the DGCA rules say, adding that the rules also apply to an aircraft operated by a person who is not a citizen of India but has his principal place of business or permanent residence of India.
