Recreational Aviation Australia Incorporated (RA-Aus) action in response to this safety issue was twofold, addressing the aircraft construction and certification aspects of the issue separately. These actions are discussed in the following sections.
RA-Aus reported that the Morgan Aero Works Cheetah Sierra 200 aircraft involved in the accident was grounded following the accident and its subsequent rebuild. It will not be re-registered unless under the RA-Aus 19- (amateur built) category.
Issuing of certificate of type acceptance
A routine Civil Aviation Safety Authority (CASA) audit of RA-Aus in November 2011 resulted in the identification by RA-Aus that:
- the Morgan Aero Works Cheetah Sierra 200 aircraft involved in the accident at Old Bar was not constructed to a known standard
- the aircraft manufacturer did not hold a production certificate issued by CASA
- the Morgan Aero Works Cheetah Sierra 200 aircraft type was not a light sport aircraft (LSA) category aircraft and did not possess a special certificate of airworthiness.
In response to these findings, RA-Aus:
- grounded the fleet of Morgan Aero Works Cheetah Sierra 200 aircraft
- removed the factory built status from the aircraft manufacturer
- advised the aircraft manufacturer to comply with LSA standards in order to regain factory build status
- deregistered all 24- (factory built) Morgan Aero Works Cheetah Sierra 200 aircraft and re-registered them under the 19- (amateur built) category.
RA-Aus also employed a new Technical Manager.
The ATSB is satisfied that the action taken by RA-Aus should lead to improvements that adequately address the safety issue.
