What happened
On 9 February 2009, a scenic flight over the Abel Tasman National Park at the northern tip of New Zealand's South Island resulted in a fatal crash. The aircraft involved was an Airborne XT-912 microlight, registered ZK-DGZ. The accident caused the death of both the pilot and the passenger.
The investigation
Following the accident, the Civil Aviation Authority (CAA) performed a technical investigation into the crash. Simultaneously, the Commission initiated an inquiry focused on the regulatory framework governing commercial microlight 'adventure aviation' flights. This sector, which encompasses activities such as ballooning, gliding, and tandem parachuting, had seen significant growth. Specifically, the number of registered two-seat microlights had more than doubled since 1997, eventually exceeding 700 aircraft.
While existing Civil Aviation Rules required pilots to hold valid commercial licenses for flights conducted for hire or reward—often under the umbrella of aviation recreation organizations—the investigation identified a significant regulatory gap: the operators themselves were not subject to certification.
Findings
An investigation into the sector revealed that while pilot certification and operating rules were in place, there was a regulatory void regarding the certification of adventure aviation operators. This lack of oversight applied to the broader commercial microlight industry during the period of rapid growth in two-seat aircraft registrations.
