The Royal Malaysian Air Force (RMAF) has set up a board of inquiry to evaluate and analyse the emergency landing incident involving its Nuri helicopter at SMK Balung near here today.

Its chief, Gen Tan Sri Roslan Saad said the board would take the necessary action to ensure that Nuri helicopters, which were now being used in its operations, are serviceable.

He said members of the board would also recover the helicopter's fuselage and components to determine the cause of the incident.

"Investigations at the scene will take three days," he told reporters at the scene.
