As a result of this report and an increase in the number of notifications the ATSB received regarding engine problems in light sport aircraft, the ATSB has commenced a research investigation into the reliability of light sport aeroplane engines.

Airservices have informed the ATSB that a review into callsign conflict has been conducted and the callsigns involved were identified as in conflict - work is underway to resolve the matter.

After REPCON questioned CASA as to whether they had discussed the falsification of the maintenance records with the operator, CASA conducted further enquires. They formed the preliminary view that the defects had not been endorsed on the maintenance release when they should have been and these matters were going to be examined further.
