During flight training, the aircraft was about to turn downwind and climbing through 900ft. At this point The instructor heard the engine RPM drop to an unsafe power setting so took command and whilst turning downwind and levelling out at 1000ft, attempted to trouble shoot as they had lost power and were continuing to do so. The instructor declared a PANPAN call requiring immediate preference to land RWY 29L. From this point they decided to glide into land and not rely on power and landed safely with no further incident, also taxiing off the runway using the aircraft's inertia.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Metal particulate found in oil filter during a routine oil change. Upon investigation it was found that a piston circlip on number 3 piston had broken resulting in the gudgeon pin becoming loose and rubbing on the edge of the crankcase. After consulting manufacturer, a decision was made to remove engine from service and return to manufacturer for repair and further investigation. DETERMINED OUTCOME: This occurrence has been referred to CASA engineering and airworthiness branch and the manufacturer for further monitoring and action where required.

While completing a 3-point landing in a tail wheel aircraft on a private grass air-strip, the tail wheel assembly cracked and broke away from the tail of the aircraft. The aircraft tail skidded along the ground dragging the tail wheel assembly by the connecting chains. The tail wheel assembly contacted and damaged the rudder and elevator control surfaces. DETERMINED OUTCOME: It is likely that the tail-wheel assembly which used a 3/4" solid aluminium rod to attach the wheel to the fuselage boom may have become work-hardened over time, causing it to crack rather than flex as intended. This will be replaced with a spring steel option.

After applying full power on the runway for a normal touch and go, the aircraft began to skid. The instructor took over from the student and verified that no brakes were applied and aborted the take-off whilst maintaining directional control. Aircraft had sustained a nose wheel collapse preventing rotation of the wheel
11/2/2018	OCC1283	St George	QLD	Aeroprakt	A32 Vixxen	Rotax	912 ULS	After refueling the aircraft with 20L of PULP which was put into the left fuel tank from a jerry can...
After refueling the aircraft with 20L of PULP which was put into the left fuel tank from a jerry can using a filtering water trapping funnel. Fuel drain was then immediately checked with nil abnormalities, and again 10 minutes later two further fuel drains revealed no abnormalities. After take-off, due to the temperature being quite warm the pilot had planned on climbing to 6500ft. At 4500ft there was loud bang/snap noise and the engine began to vibrate and shake. The pilot reduced the throttle to idle, made an emergency call and because of the altitude and the westerly wind made the decision to turn back to YSGE for an emergency landing. The pilot flew parallel to the RWY and due to the engines behavior elected to turn both ignition switches off. The aircraft reached the eastern most end of the bitumen approx. 1NM S of the strip. The pilot then applied 10 degrees of flap and made a gentle descending U-turn setting up the approach for the RWY into the wind, because of this wind the aircraft was approx. 0.5NM from the end of the runway at 1000ft. Using a side slip method, the aircraft touched down on the keys with a very smooth landing. DETERMINED OUTCOME: The RAAus Technical Manager attended the engine tear down and it was identified that the inlet value from number one cylinder ended up in no 3 cylinder. Crank was found to have a 1/2mm twist. A representative from the Rotax factory attended and viewed the torn down engine. It appears that a manufacturing fault had occurred to a push rod and this part some how made its way into the engine. The push rod has then failed which caused the rocker and valve not to operate correctly and the engine then seized. Rotax to review how this error occurred internally and will supply and fit an new 912 to the effected owner of the LSA

After an uneventful flight to Caloundra and Glass House Mountains area the aircraft joined the circuit for RWY 30 and commenced to carry out touch and goes in the circuit. Due to a wind change so the aircraft moved to RWY 06 to do a touch and go. That touch and go was uneventful to that point and the pilot proceeded to take off again but noticed on climb out that it took longer to reach 500ft for the first turn. The engine was observed to be running rough and on turning onto crosswind I noted there was loss of power with revs down to 2,600 and the aircraft was vibrating/shaking from the rough running engine. The pilot checked that the carby heat control was closed and then immediately applied carby heat. This action made no difference and the engine continued running rough and still at only around 2,600 rpm so they closed the carby heat control to cold. The pilot continued on with the FCOST checks but nothing else seemed to be obvious apart from a slightly high oil temperature and the rough running engine continued. The pilot checked around them and kept flying down wind maintaining 600ft for the closest RWY being 12. A PanPan call was made to alert Caboolture Traffic of the partial loss of engine power and advised Caboolture Traffic on 125.85 that the pilot needed the immediate use of RWY 12 as other traffic was using RWY 06. The pilot continued downwind for RWY 12 with the available power and made a glide approach and uneventful landing on RWY 12. Determined Outcome: The fitted engine was a first generation Gen 4. The detected fault was a crack in the head of the No 5 cylinder. Jabiru identified that this may have been caused by a machining flaw during manufacturing. Jabiru have identified other engines that may have been affected and supplied modified head/barrel assemblies to the aircraft owners.

Approx. 10mins after take off the GPS started flickering on & off. Then about 10secs after that the entire electrical system failed. The PIC had the PAX text messaged the instructor at Maryborough to see if clear to land. The aircraft landed uneventfully. DETERMINED OUTCOME: This was an electrical fault caused by a voltage regulator becoming inoperable. This is an issue that cannot be detected and can happen at any time. Rotax are aware of the continual voltage regulator issues. Due to time in service its impossible to determine the length of service or operational conditions this part has been exposed to. Pilot and pax handled situation correctly.
10/2/2018	OCC1282	1KM West of Tumut Airfield	NSW	Jabiru	J170c	Jabiru	2200B	The pilot called inbound at 10mi out and had no reply, so started to descend from 5500ft. The pilot ...
The pilot called inbound at 10mi out and had no reply, so started to descend from 5500ft. The pilot positioned the aircraft west of and parallel to the strip about 1Km from the centre line and descending through about 2200ft for a mid-field cross wind joining pattern for RWY17 at 1900ft. The pilot passed the 17 threshold and had been checking the strip on the left, when they looked forward again in preparation to turn crosswind a trike with 2 on board flew past the starboard side, (heading North). The pilot first saw the trike at about the 1-2 o'clock position at their level less than 50m from them. After they passed the pilot heard no communication from the other pilot. OUTCOME: The investigation revealed differing recall of the proximity relating to this occurrence making a determination impractical. Pilots are asked to keep a high degree of visual situational awareness when operating in the vicinity of uncontrolled aerodromes and use radio for "alerted" see and avoidance but not become reliant on radio only.
9/2/2018	OCC1318	Redcliffe aerodrome	QLD	Arion	Lightning	Jabiru	3300	During take-off, when about 10ft in the air, a duck flew up from the left side of the aircraft and f...
During take-off, when about 10ft in the air, a duck flew up from the left side of the aircraft and flew into the prop and then impacted the inboard leading edge of the right wing. The pilot did not feel or hear the prop blade impacting the duck but the carcass made a thud when it impacted the leading edge of the wing. The pilot climbed to 500ft at reduced power and alerted local traffic that the aircraft had just had a bird strike and was making a precautionary landing from a low level circuit. The aircraft and engine were operating as normal. On short final the pilot saw the carcass of the duck on the side of the airstrip. The aircraft was taxied off the RWY and inspected for damage and none was found. OUTCOME: No action required by RAAus.

During a circuit flight in Moorabbin Airport. On final the tower gave the aircraft a Touch and Go clearance. The pilot replied with the read back but no "TX" signal was shown on the avionics panel. The tower repeated the clearance once more but was unable to get our reply. The pilot performed a go-around and attempted to restart the avionics switch and panel. The panel failed to show sufficient battery charge, 7.5V instead of 12V. The avionics panel was not switched on successfully. The aircraft squawked 7600 and performed a full stop with a green light from the tower. DETERMINED OUTCOME: This aircraft is now grounded while the old avionics systems is removed. A new Garmin G3X instrument panels and associated equipment is now being installed.
