OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot was test flying the kit built aircraft, the first touch and go was completed without incident on a sealed runway. The second circuit was completed with a touch and go on the grass runway. After applying power and climbing everything was normal until around 175ft above ground when significant rudder aerodynamic flutter began. With airspeed at 80mph the nose was pushed forward while reducing power the rudder pedals were oscillating severely and could not be contained. The pilot momentarily removed their feet from the rudder pedals to see if it would settle, the flutter continued. The stick was stable with no vibration. The engine was cut to idle the rudder flutter continued. The rear of the aircraft was now vibrating the whole airframe and the pilot chose to push the plane back onto the ground. Touching down at high speed approx. 125ft before the boundary fence, full brakes were applied and the pilot attempted to ground loop the aircraft to avoid or lessen the impact with the boundary fence. Approx. 20ft from the fence the left rudder pedal broke off under the high pressure of braking. The aircraft veered approx. 90 degrees to the right and impacted the corner section of the boundary fence. The nose impacted one of the three posts and the wing strut impacting the rail between the other two posts. The tail impacted the wire fence breaking the left stabiliser off the tubular boom and severely damaging the lower part of the rudder. The nose was crushed up to the pilots’ feet. On impact the throttle was advanced due to the inertia of the impact the pilot immediately reduced the power to idle and went through the shutdown procedures.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst an instructor and student pilot were conducting pre-flight checks in the designated run-up area, they heard an incoming VH registered aircraft announce that they were going to execute a “Straight in approach” in Redcliffe aerodrome. The ERSA states in item 6 of the Noise Abatement section pertaining to YRED that “No straight in approaches are permitted at YRED”. This occurrence was submitted to CASA for follow-up. Members are reminded to review and follow appropriate aerodrome procedures prior to operation.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft was being test flown and had done approx. 4 hours at the time. It was at 1200ft and overhead the airfield at the time when the pilot felt a slight hiccup in the engine. The pilot managed return and land safely then taxi back to the hangar. Upon investigation it was found that the number 5 cylinder piston connecting rod had disintegrated into 5 separate pieces and done severe damage to the lower cylinder barrel and crank case.
28/5/2020	OCC2032	Caboolture	QLD	Flight Design	CTSW	Rotax	912ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Ref to ROTAX 912ULS Cylinder Head MM Assembly Proce...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Ref to ROTAX 912ULS Cylinder Head MM Assembly Procedures. Collar CAP nuts found to be incorrectly fitted and (x2) seized onto M8 Stud. Cyl#3 (top right stud) and Cyl#4(top right stud) found to be affected. Cyl#3 capped nut freed from M8 stud with smart tap to wrench. Cyl#4 capped nut remains seized to M8 stud. M8 Stud rotates 3mm either way with collar nut and is unable to be loosened. (Top of capped nut had to be cut away to observe the stud and to inject penetrant). It appears that the Thread Sleeve M8 may be rotating inside the block. Observations: Collar CAP nuts have been fitted (in 2017) on top side cylinder head studs. (the capped cylinder head nuts should be inside the rocker cover). Logbook maintenance entry (2017) indicates nuts were tightened to 10Nm + 180 degree turn. Latest rev 912 MM indicates procedure as - 10Nm + 120 degrees. 'Optional' SI-912-025 2016 indicates procedure as - Step 3 - Loosen each M8 collar cap 360 degrees then tighten to 10Nm + 150 degrees. Engine reported to have been, and still is leaking oil.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst conducting and on the last circuit of a lesson based on Circuit emergencies, the Warning caution lights for the Rotax 912IS Lane A and Lane B (ecu redundancy circuits) both started flashing and a warning appeared on the Dyson Skyview system instructing to land immediately. A quick scan revealed the number 1 Exhaust gas temperature was indicating 1200 degrees Celsius, a PAN was declared and an uneventful glide approach conducted without further incident. Fault finding revealed that the number 1 Exhaust gas temperature sensor had failed. Sensor replaced and nil defects identified.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Coming in to land, the aircraft had touched down when the pilot felt a shimmy in the nose wheel. The pilot applied back pressure to lift the nose wheel off the ground for as long as possible. When the nose wheel touched down, the aircraft veered to the left. At this time the aircraft was travelling slow enough that they were able to apply the brakes and bring the aircraft to a complete stop. At this point the pilot didn't know that the nose wheel steering was completely lost and they attempted to turn the aircraft around and taxi off the runway. When the pilot realised this was not possible they turned the aircraft off, made a radio call advising another aircraft that was in the circuit of their intentions to get out of the aircraft and push it off the runway to the nearest taxi way, to which the other pilot acknowledged the call. Once this was completed, the pilot made a radio call advising they were clear of all runways.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: While conducting lesson on circuits, the instructor attempted to demonstrate engine failure after take-off and return to the runway. Power was reduced to idle, adopted airspeed 65/70 knots and lowered the nose to maintain airspeed. The pilot attempted to round out, however as they rounded out struck the ground resulting in a very heavy landing. The Instructor was requested to complete a review with the CFI, however has moved from the location and is no longer instructing. Prior to return to instructing a review process will be required. Members are reminded of the risks involved in attempting to turn back to the runway in an emergency and should elect to land straight ahead.
17/5/2020	OCC2021	Archerfield Aerodrome	QLD	The Airplane Factory	Sling 2	Rotax	912	OCCURRENCE DETAILS SUBMITTED TO RAAUS: Radio Failure during arrival (Transmit failure) at YBAF. The...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: Radio Failure during arrival (Transmit failure) at YBAF. The pilot requested clearance and read back the clearance, however Tower could only receive the carrier wave, no transmission modulation and requested an acknowledgement of the clearance. The pilot repeated the last transmission again. Again no reception by tower. They then transmitted in the blind "change of intention, full stop at RWY 10R" – the tower could only receive the carrier wave. The tower then requested that the pilot click twice if they were receiving, which the pilot did. The aircraft landed safely on RWY 10R. Further clearances to taxi back were transmitted by the tower and acknowledged by the pilot with 2 clicks as requested.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pin pressed into the aileron that then slides through to the wing hanger had become loose and slid out causing the outer part of the aileron to drop free of the wing. Information was sent to aircraft manufacturer who have issued service instruction.
16/5/2020	OCC2019	Launceston Aerodrome	TAS	Jabiru	J160C	Jabiru	2200CC/CI	OCCURRENCE DETAILS SUBMITTED TO RAAUS: On taxi to the runway, the brakes failed approaching the hold...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: On taxi to the runway, the brakes failed approaching the holding point. The pilot reduced the power to help bring the aircraft to a stop before the holding point. This was not possible and the pilot diverted off the taxiway into grass to avoid breaching the active runway.
15/5/2020	OCC2024	Port Macquarie Aerodrome	NSW	The Airplane Factory	Sling 2	Rotax	912ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: The lesson was running late and the aircraft had not been fu...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: The lesson was running late and the aircraft had not been fuelled the previous day. The instructor was organising to refuel the aircraft and had student take aircraft out of the hangar. This break to the instructors’ normal routine combined with the time pressures meant they neglected to remove the tow bar from the nose wheel of the aircraft. They started the aircraft, taxied to runway, completed run-ups and taxied onto runway 21. Throughout these sequences, neither the instructor or the student detected anything wrong and did not hear anything out of the ordinary (the instructor was wearing an active noise cancelling headset). The student began the take-off roll and a noise was detected as speed increased that sounded like wheel bearings scraping. Just after lift-off the instructor took over and landed the aircraft and taxied back off the runway. The instructor exited the aircraft and found the towbar still attached but trailing behind the nose wheel.
12/5/2020	OCC2017	Cessnock Aerodrome	NSW	Jabiru	J230-C	Jabiru	3300A	OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot flew from Mudgee to Singleton at 7500ft then cruise...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot flew from Mudgee to Singleton at 7500ft then cruise decent to Cessnock 1200ft. Shortly after joining the circuit, downwind runway 35, the aircraft was abeam the threshold the engine ran rough and began to lose power. The aircraft was following another who was 1/2 a mile ahead so the pilot called turning base 35 for a full stop and flew an abbreviated circuit. All went well and the pilot exited the runway with communication. Review identified likely cause due to carburettor icing.
