A technical snag was reported from the aircraft carrying Prime Minister Narendra Modi on Friday as he was in Jharkhand for election campaigns at the Deoghar airport.
The glitch did not put PM Modi or the crew at risk but his return to Delhi got delayed.
He was visiting Jamui to attend a function organised on the 150th birth anniversary of Birsa Munda, which is celebrated as 'Janjatiya Gaurav Divas'.
An official told PTI, "The PM has been at the Deoghar airport for more than an hour now. What would be the alternative arrangement for his return to Delhi is being discussed."
As a result of this, a 'no flying zone' was declared in the region's air space, officials said.
Rahul Gandhi Also Stuck In Jharkhand
Leader of the opposition Rahul Gandhi was stuck in Godda, where he addressed an election rally, as his helicopter could not take off following the 'no fly zone' advisory.
Later, the Congress alleged that Gandhi was targetted unfairly by the administration.
"Our leader Rahul Gandhi's helicopter was not allowed to take off for about two hours, posing a grave threat to his life. This was a security lapse at the behest of the Centre," state minister Deepika Pandey Singh alleged.
