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.
9/7/2017	OCC1094	Wagga Wagga	NSW	Jabiru	J230c	Jabiru	3300	During a local flight, at approx. 10m N of YSWG and 2000ft altitude engine started to run rough. Th...
During a local flight, at approx. 10m N of YSWG and 2000ft altitude engine started to run rough. The pilot made a mayday call on local frequency 126.95 to gain a clear track for entry to RWY23, when at 3m from YSWG the engine failed completely. The pilot then found a suitable paddock and executed an uneventful emergency landing. DETERMINED OUTCOME: RAAus Technical team have engaged with the owner and manufacturer to attempt to enable further investigation. Possible valve failure due to high EGT readings. At this stage RAAus cannot take any further action.
6/7/2017	OCC1090	Camden airport	NSW	Jabiru	160C	Jabiru	2200	OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Prior to takeoff, a “full and free” control check was...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Prior to takeoff, a “full and free” control check was completed normally. During the takeoff roll, abnormally light back pressure was noticed on the control yoke and the takeoff immediately aborted. Inspection of the cable indicated that the flared mouth of the tubing, designed to retain the tube in the flexible housing while allowing some lateral movement, had been flattened, allowing the tube to disengage.
13/6/2017	OCC1080	Dunmarra	NT	Jabiru	J160	Jabiru	22A	Aircraft was at ground level and the wind was indicating to the pilot to be coming from the North. T...
Aircraft was at ground level and the wind was indicating to the pilot to be coming from the North. The pilot observed debris being blown in the same direction and the wind was felt on the aircraft. The pilot headed into the wind and quickly reached 60 knots IAS. The pilot then rotated the aircraft which resulted in the stall warning 'screaming' and the aircraft failed to climb more than a few feet. On returning to the ground the aircraft came down at an awkward angle with a loss of control resulting in the aircraft ending up on the roof in the bushes. OUTCOME The take-off from a private airstrip was conducted downwind, although wind on the ground was calm. As a result, the aircraft airspeed was not managed effectively resulting in the aircraft stalling, landing on a nearby road. The pilot has since completed additional retraining in management of windshear, flying using attitudes, local weather and VMC criteria along with a BFR with a local CFI.
4/6/2017	OCC1067	Canberra	ACT	Jabiru	J230D	Jabiru	3300	Approaching YSCB from the south at 6500' the pilot requested clearance to enter Class C and climb to...
Approaching YSCB from the south at 6500' the pilot requested clearance to enter Class C and climb to 7500' to avoid cloud. When told to wait outside controlled airspace because approval would be ten minutes, the pilot chose to descend under the Class C steps and under the cloud. There was plenty of clearance between cloud and terrain. While descending, the pilot entered the southern sticking-out part of the 4500' step at around 4900'. ATC noticed the threatened separation violation, cancelled the RPT descent and told the pilot to turn right, head west, and stay out of controlled airspace. It wasn't until the pilot completed the 270 degree turn and was checking out the westward track on the chart that they realised they were in a 4500' area. Outcome: Visual navigation with reference to ground features was compromised by cloud cover during unplanned descent. Pilot was expecting an airways clearance and did not effectively plan alternate tracking to remain clear of CTA. The pilot held all appropriate qualifications to conduct flight and utilise his GA qualifications to request the clearance. No further action taken by Operations.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Rear braking caliper and brake pads on port side, separated from attachment point to the wheel strut, due to metal fatigue. OUTCOME: Inspection of aircraft highlighted defect. RAAus recommends for the owner to go back to the manufacturer regarding the defective part. The owner has suggested the inclusion of inspections of the mounting bracket at the attachment point to the wheel strut for metal fatigue for 100 hrly inspections of the landing gear.
26/5/2017	OCC1057	Wedderburn Airport	NSW	Jabiru	J120C	Camit	2200	Coming in for full stop landing on 17, just prior to touchdown the aircraft lost directional control...
Coming in for full stop landing on 17, just prior to touchdown the aircraft lost directional control due to local gusting winds. In trying to correct the aircraft back onto the RWY, it hit a culvert running parallel to the RWY and as a result crossed the TWY and ended up in a hedge. OUTCOME: Possible factors include differences in aircraft response compared to the aircraft used to gain the Pilot Certificate and increased response time due to the pilots age. The pilot will complete further flights with an Instructor particularity as an order has been placed for a different brand of aircraft as a replacement. RAAus Operation Managers remind pilots of the importance of type training when flying a new aircraft and encouraged to seek assistance from Instructors if required.
23/5/2017	OCC1048	Caboolture	QLD	Jabiru	J160C	Jabiru	2200B	While the aircraft was on a take-off run, a kangaroo ran/hopped into the aircraft path and impacted ...
While the aircraft was on a take-off run, a kangaroo ran/hopped into the aircraft path and impacted with the aircraft causing mild damage to the propeller and engine. OUTCOME: Caboolture Airfield has had numerous reports of bird strikes however this is the first kangaroo strike reported to RAAus. Members are advised that the ERSA for this airfield has highlighted that kangaroo and bird strikes exist (see http://www.airservicesaustralia.com/aip/current/ersa/FAC_YCAB_25-May-2017.pdf for more information).
