On 9 December 2015, the holder of supplemental type certificate SVA521, Rebel Ag Pty Ltd, advised the ATSB that, at their request, the Civil Aviation Safety Authority (CASA) had suspended the certificate. The suspension came into effect on 20 August 2015. The notice of suspension specifies that the suspension ceases on release of the ATSB’s investigation report into this accident.
Until the release of the ATSB’s investigation report into this accident, the outcome of the action by Rebel Ag Pty Ltd to seek suspension of supplemental type certificate (STC) SVA521 prevents its operational use, thereby addressing the safety issue. However, release of the ATSB’s investigation report rescinds the suspension of STC SVA521. The ATSB will monitor the status of the STC approval following the release of this investigation report.
