Air India One, a Boeing 747-400 aircraft carrying Prime Minister Narendra Modi from Delhi to Berlin after halts at Paris, Toulouse and Hannover, developed technical snag and had to replaced by another plane.

The standby plane, kept in readiness in Mumbai, left early Tuesday morning for Berlin and was used for flying the Prime Minister and his entourage to Ottawa in Canada on the last leg of his three-nation tour, Air India sources said.

Air India has also sent some additional cabin crew along with the aircraft.

As part of the protocol, the national carrier keeps one of its jumbo aircraft on the standby mode for such situations, they said.

The Prime Minister had left Delhi for Paris on April 9 and is scheduled to return here on the morning of April 18.
