He says the CAA is committed to doing all within its power to minimise the risk of drug and alcohol use in adventure aviation. The issue has been raised as a concern during the inquest and was also the subject of a recommendation in the Transport Accident Investigation Commissions report on the accident.
"The regulatory system for the safety oversight of commercial balloon operations has changed considerably since the time of the accident. Several measures which address the families concerns are already in place," he said.
"Aviation safety is our top priority and the CAA is fully supportive of the recommendations made by the Transport Accident Investigation Commission in its report on the accident.
"In particular, we welcome the work currently underway to consider the commissions recommendation to introduce a legislative and a regulatory framework to reduce the risk of alcohol and drug use across the transport sector."
The CAA would not comment further until the conclusion of the inquest.
