The grounding order was issued on 20 July and was due to run until 3 August, but was lifted early as CASA found there was no evidence for an unsafe condition, and the EASA said the wrecked aircraft had been exposed to aerodynamic loads beyond the limits specified in the type-certification basis.

CASA also prohibited operation of the aircraft in Australian airspace effective 20 July for 15 days, but with an option to extend the timescale.

[15] This report concluded that, approximately 30 seconds before the parachutists were due to jump, the aircraft stalled and subsequently entered cloud in a rapid and accelerating descent.

Lack of pilot experience and loss of visual cues precluded a subsequent recovery to controlled flight.

The resultant loss of longitudinal stability, combined with already low and decreasing airspeed at a time of high pilot workload probably led to the departure from controlled flight.
