A helicopter was seriously damaged in an accident at Norwich Airport. 

A report published by the Air Accident Investigation Branch revealed that the aircraft crashed at the airport on return from a flight on the morning of November 13.

As the 2012 AgustaWestland AW139 helicopter taxied to the parking area, the 35-year-old pilot hit a lamppost after confusing the airport's ground markings.

Safety changes were made after the investigation found that the pilot, who was unfamiliar with Norwich Airport, had confused the perimeter line for a taxiway line, leading him to take the wrong path.

The stands were resized for different helicopters in the early part of this year and new surface markings were painted. 

Pilots unfamiliar with the airport now have a marshal to help them park.
