The helicopter's tail rotor has been damaged in the crash-landing.

Six pilgrims on board a private helicopter had a narrow escape on Monday when the tail end of the chopper hit an object while making an emergency landing at Kedarnath helipad soon after take-off.

The pilgrims were returning from Kedarnath to Fata in the helicopter when the pilot soon after the take off realised that it had developed a technical snag, Rudraprayag District Disaster Management Officer Harish Chandra Sharma said.

"As the helicopter was making an emergency landing on the helipad its rear portion hit an object, perhaps a railing," he said.

"Luckily, all on board the helicopter are safe," he said.

Seven persons, including the pilot, were on board the helicopter when the incident took place, he said.
