The aircraft with four crew members on board flew over Jodhpur airforce area without permission before its scheduled landing at the Sanganer Airport in Jaipur for refuelling last evening, officiating Director, Sanganer airport, P Krishna, said here.
"The aircraft deviated from its scheduled route but was being monitored. We got information from Delhi ATC about the violation so the aircraft was grounded (at Sanganer airport) and the pilot Ibrahim was questioned," he said.
"Intelligence agencies were also informed. We examined the technical details and submitted our report to the DGCA," he said.
According to the pilot, the aircraft had deviated from the route yesterday because of some technical problem in the GPS system.
He said the Directorate General of Civil Aviation gave clearance to the aircraft today as "nothing suspicious" was found in the investigation.
"The aircraft is now leaving for its destination. Since it was a violation, we gave the pilot a warning letter in this regard," Krishna said.
