OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: During CCTs the pilot noticed an engine vibration and made full stop landing. An investigation revealed low compression on No 1 cylinder, further investigation revealed a cracked cylinder along a machined surface. All cylinders were replaced with replacement cylinders supplied by the manufacture which included a modification to the machined surface. DETERMINED OUTCOME: This issue has been referred to CASA Airworthiness and Engineering section. As it is a registered LSA RAAus is limited in what it can do to resolve this issue.
7/10/2017	OCC1178	Canberra	ACT	Jabiru	J230D	Jabiru	3300A	The aircraft engine surged 5 times during climb out, at approx. 3500 ASL. The pilot returned immedia...
The aircraft engine surged 5 times during climb out, at approx. 3500 ASL. The pilot returned immediately to Canberra airport, no further problems during remainder of the flight. The pilot ran an engine check after landing, magneto test & carby heat, all were OK. On close examination, the underside of the carburetor was found to have extensive fuel stains. New carburettor installed. No further issues identified.
6/10/2017	OCC1163	Albany Regional Airport	WA	Jabiru	J170C	Jabiru	2200B	Normal take-off on RWY05. At approximately 300ft the engine suffered significant loss of power accom...
Normal take-off on RWY05. At approximately 300ft the engine suffered significant loss of power accompanied by vibration/rough running. With insufficient runway remaining to land, performed a gentle turn back towards the threshold of RWY14. The pilot found that with reduced throttle the engine could maintain about 1800rpm. The pilot elected to perform a tight sweeping approach back onto RWY05 (which was more into wind) rather than land downwind on 14. The landing was uneventful. Upon shutdown oil was found leaking from around the exhaust manifold #4 cylinder, the plugs on #4 cylinder were totally oiled up. DETERMINED OUTCOME: This occurrence has been referred to CASA engineering and airworthiness branch and the manufacturer for further monitoring and action where required. It appears a valve failed.

The pilot maintained too much pressure with their right foot on the rudder, resulting in the aircraft veering sharply to the right and hitting a tree sustaining minor damage. DETERMINED OUTCOME: A detailed ground based review was conducted with CFI to revise strategies for control management and authority during critical flight phases. The student training records were reviewed and prior training deficiencies discussed. The aircraft has subsequently been fully repaired by the manufacturer and returned to service.
1/10/2017	OCC1170	Caboolture	QLD	Jabiru	J160D	Jabiru	2200B	During approach and again on final approach, the crew of a Cessna 172 observed the Jabiru in close p...
During approach and again on final approach, the crew of a Cessna 172 observed the Jabiru in close proximity. No radio calls were heard from the Jabiru. The PIC of the Jabiru noted they were positioned outside the gable markers in the locally accepted location for run-ups. There are no taxiways or run up areas at Caboolture and no radio calls were received from the Cessna pilot.

The aircraft experienced an RWY excursion whilst attempting a go around. Outcome: Loss of Control (RLOC) whilst conducting missed approach. Member self analysis to undertake more practice on missed approaches and aircraft handling. No further action required at this time.
9/9/2017	OCC1142	Coolah	NSW	Jabiru	J230D	Jabiru	3300A	The Jabiru was departing Coolah on gravel RWY08 and at the time of rotation appeared unable to climb...
The Jabiru was departing Coolah on gravel RWY08 and at the time of rotation appeared unable to climb under full power and appeared to be buffeted by wind shear forcing aircraft sharply to the left. As they were still at speed towards a fence, which was outside the cone markers and, parallel to the RWY the pilot had to make a decision to hit the fence or try to clear it. The aircraft came into contact with the fence and was subsequently flipped onto its back. OUTCOME: The primary cause determined was the inability of the aircraft to reach minimum climb airspeed and maintain minimum control airspeed within the takeoff distance available resulting in an a Runway - Loss of Control accident (RLOC). Contributing factors were local convective conditions affecting wind direction. Members are reminded of the importance of selecting and referencing an appropriate takeoff rejection point based on environmental conditions presented at the time of the flight.
2/9/2017	OCC1140	Cambrian Hills	VIC	Jabiru	J-160 C	Jabiru	2200B	During a training flight, approx. 10NM south of Ballarat Township when the engine started to lose po...
During a training flight, approx. 10NM south of Ballarat Township when the engine started to lose power and intermittently ran rough 45mins into the lesson and the instructor was unable to maintain height. The instructor immediately selected carburettor heat, maintained safe airspeed, selected a force landing field and completed the forced landing checks. The instructor performed a forced landing into the selected field with no physical injuries experienced by student or instructor and only minor damage to the aircraft spats and propeller blade. Shutdown checks were then completed and evacuation occurred with the aircraft tied down and secured. The NAIPS ARFOR and TAF YBLT and AWIS was obtained/discussed as part of the pre-flight/lesson brief with the student, highlighting the probability of carburettor ice and the procedures to be adopted. The conclusion that could be drawn from the weather conditions was that carburettor ice was the likely factor. DETERMINED OUTCOME: Partial Engine failure with Carburettor icing was the most probable cause. Investigation with the CFI confirmed that appropriate flight planning in relation to icing likelihood and judicious use of carb heat control was used but was unsuccessful in preventing power loss resulting in the CFI conducting a successful forced landing.
30/8/2017	OCC1128	Private Airstrip Gnaraloo	WA	Jabiru	J230C	Jabiru	3300A	The aircraft bounced on runway after encountering some "sink" on landing. On the bounce a crosswind ...
The aircraft bounced on runway after encountering some "sink" on landing. On the bounce a crosswind forced the aircraft off the left hand side of RWY. The left hand undercarriage and nose wheel folded under the fuselage. The nose hit the ground stopping the engine and coming to rest 250m from the beginning of the RWY. OUTCOME: The pilot is aware of the relevant factors behind this accident and will be undertaking some additional training in other disciplines including gliding and GA aerobatics which will broaden his experience and assist his skill level.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: After 45.1hrs number 1 cylinder was found to be low in compression, upon investigation outer valve spring was found to be broken. These springs were the latest spec manufacturer supplied double valve springs. The manufacturer has supplied replacements and broken components have been returned to the manufacturer for inspection. OUTCOME: Incident has been refereed to Airworthiness and Engineering branch of CASA for ongoing monitoring.
16/8/2017	OCC1121	Temora	NSW	Jabiru	J230	Jabiru	3300	OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: During the course of a RAAus school inspection it was...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: During the course of a RAAus school inspection it was identified that the factory built LSA Jabiru used for flight training was fitted with a Cummins spinner. Notation of the fitment was noted in the aircraft maintenance logbook but with no maintainer authorisation as per TM requirements. Further investigation revealed supply of a spinner on a Jabiru invoice which was later identified to be a factory approved spinner. A telephone call to Jabiru confirmed the Cummins spinner was not approved by Jabiru and needed to be replaced with the factory approved unit to remain compliant with LSA requirements. Subsequently the CFI/L2 replaced the spinner with the approved item that was available and the aircraft was returned to service. Outcome: Defect has been resolved. No further action required by RAAus.
5/8/2017	OCC1112	Latrobe Regional Airport	VIC	Jabiru	160C	Jabiru	2200	While taxiing to the run-up bay, the right hand tyre went flat. The 4 AN4-11A bolts had sheared. ...
While taxiing to the run-up bay, the right hand tyre went flat. The 4 AN4-11A bolts had sheared. Determined Outcome: RAAus is currently developing L1 and L2 training process to address these types of issues. It would appear that this is a high time aircraft and that the routine maintenance and servicing has not been correctly implemented.
25/7/2017	OCC1176	Winton	QLD	Jabiru	J170-C	Jabiru	2200B	During the flight, following major service at YBMA, radio reception became gradually worse, then U/S...
During the flight, following major service at YBMA, radio reception became gradually worse, then U/S approx. 30mins from YLRE. The pilot noted that Voltmeter showed 9v, it was showing full voltage at start of flight. The pilot turned off all electronics other than transponder, contacted Brisbane centre by phone to alert incoming YLRE and proceeded with flight without incident. Examination next day found wires from stators to the regulator had become disconnected, possibly because cable ties grouping various leads had been pulled very tight causing the disconnection. Outcome: the PIC as self-identified the issue. No further action required by Safety.
21/7/2017	OCC1102	Gawler Airfield	SA	Jabiru	J170C	Jabiru	2200B	During a touch-and-go landing, an aircraft was observed in close proximity of a parked glider on RWY...
During a touch-and-go landing, an aircraft was observed in close proximity of a parked glider on RWY 31. Outcome: There was a misunderstanding between the PIC and trainee. This resulted in the aircraft landing on the bitumen vice the left side strip. The PIC and trainee debriefed this issue at length. All pilots are reminded of the importance of clear and concise communication both during pre-flight planning and within the cockpit.
12/7/2017	OCC1186	10nm N of Lilydale	VIC	Jabiru	J230D	Jabiru	3300A	Airspace infringement. The pilot was unaware they had entered CTA until advised later. The pilot is ...
Airspace infringement. The pilot was unaware they had entered CTA until advised later. The pilot is usually very conscious of the height restrictions and aware of the limits on the route as they fly it frequently. It is possible that it was a loss of concentration or as it was an unconfirmed altitude, transponder error. The pilot will have the transponder calibration checked. DETERMINED OUTCOME: While attempting to ensure accurate hemispherical levels were maintained the pilot penetrated the lower limit of a CTA step. Members are reminded they can significantly reduce the risk of inadvertent operation in CTA by ensuring careful flight planning is carried out prior to the flight and using known geographical features to ensure controlled airspace is avoided. Hemispherical levels are not mandatory below 5000' AMSL, however where possible pilots are encouraged to plan at these levels if operating below 5000' AMSL.
