The Transport Accident Investigation Commission is appealing for witnesses to the hot air balloon accident near Ashburton.

Emergency services were called to Lyndhurst Road about 9.10am on Saturday.

TAIC Chief Investigator of Accidents Harald Hendel said “the balloon pilot was ejected from the basket during a rough landing, was caught in a rope and dragged some way before the balloon came to rest and the basket tipped over.”

“The pilot is reported to have been seriously injured in the accident, and was taken to hospital.”

“We have heard of no other injuries to the seven others reportedly on board.”

Mr Hendel says the Commission has appointed a TAIC investigation team of two, who are travelling to the accident site today.

“The Investigation team’s evidence collection work is broad to support the many routes that an investigation could follow.

“Over the next several days, TAIC’s investigators will gather evidence about the accident scene, secure wreckage and electronic records such as photos, videos, and location data on the cellphones of the balloon occupants.

“We’re interested in what the balloon occupants recall, along with the relevant professional and personal backgrounds of the pilot and other operator staff, what they knew, thought, experienced, and did.

“We’ll be looking at the balloon, basket and other elements of the aircraft, its individual and type history, performance, maintenance, design.

“The operating environment is also of interest, including physical, weather, operating company safety system, organisational culture of the operator, traffic control, regulatory matters.

Hendel said they are particularly keen to receive photographs or videos of the balloon.

The Transport Accident Investigation Commission opens an inquiry when it believes the circumstances of an accident or incident have – or are likely to have – significant implications for transport safety, or when the inquiry may allow the Commission to make findings or recommendations to improve transport safety.
