The incident had happened over Banihal in Jammu and Kashmir.
In a written reply, the minister of state for civil aviation said that on June 30, 2017, Border Security Force EMB 135 BJ aircraft was involved in an occurrence with an IndiGo aircraft while operating flight from Srinagar to Delhi.
"During the flight, traffic advisory was generated due to wrong selection of QNH (Altimeter setting)," Sinha said.
He also said that due to the error on part of BSF crew, "appropriate action is warranted against the crew by BSF".
On that day, the two aircraft came perilously close to each other and an automatic alert went off.
There were 180 passengers on board the IndiGo aircraft and 12 on the BSF plane, sources had said earlier.
According to the minister, on June 30, an IndiGo airline was involved in rejected take off due to engine no 1 stall warning followed by smoke from the cabin during take off roll at Patna airport.
All the persons onboard the aircraft were evacuated on the runway. There was no injury to any person during evacuation, Sinha said.
For the incident at Patna, "no action is called for against personnel of the airline," he noted.
The minister's reply was to a query whether major air accidents were averted in Jammu and Kashmir and Patna on June 30.
