OCCURRENCE DETAILS SUBMITTED TO RAAUS: After landing from their second circuit solo a student vacated at TWY B RWY 35R and was instructed to hold short of RWY 35L. The student came to a stop but had crossed the yellow hold short line. This resulted in a runway incursion. An aircraft on final went around and the student was given clearance to cross the runway. Procedures at the FTS have been reviewed by Operations and the CFI, with changes to Instructor processes to reduce recurrences.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft engine seized at approx. 80ft above RWY. The aircraft landed on the remaining RWY without further incident. Initial causes leading up to the failure are undetermined however the final cause of engine stoppage was the number 1 con rod bearing cap separation and piston skirt failure after number two main bearing seizure. Indications leading up to this failure were a rapidly increasing engine oil temperature and sluggish engine acceleration. No further action required

OCCURRENCE DETAILS SUBMITTED TO RAAUS: During flight there were issues with the engine running rough as a result of no fuel pressure. The electric pump was turned on and the engine returned to life, however it wouldn't keep pressure up without it. OUTCOME: Primary cause most likely vaporization of the fuel due poor quality.
28/10/2018	OCC1538	Bodangora Aerodrome	NSW	Australian Aviation Works	Karasport	Rotax	582	OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst ferrying an aircraft to Wakefield from Cowra there was...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst ferrying an aircraft to Wakefield from Cowra there was a planned fuel stop at Dubbo, however as the aircraft approached Wellington the engine began to misfire. The condition gradually worsened so the pilot decided to fly to Bodangora airfield to make an emergency landing. The pilot had phoned a fellow pilot who lives in Wellington and had been informed of the drag races being conducted on the day. The engine continued to misfire as the aircraft approached, the pilot radioed twice that they were to make a straight in approach on RWY 09 but received no acknowledgement of the calls on Unicom 126.7. The aircraft landed without incident. Follow up with the aircraft owner revealed the spark plugs were replaced, with the engine operating normally as a result

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The amphibious aircraft enacted a water landing without raising the undercarriage. The event actually started with a departure from land, with no change in wheel position. Distraction during the landing phase resulted in complacency regarding completion of the checklist. Waterborne pilots are recommended to use triggers to conduct pre-landing checks at nominated points in the landing phase, including a final check for surface, confirming wheel position at that time.
27/10/2018	OCC1518	Clifton Aerodrome	QLD	Austflight ULA	A-582	Rotax	582	OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst conducting a check ride, the approach airspeed decayed...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst conducting a check ride, the approach airspeed decayed to 50kts in gusty conditions and the aircraft was caught by a wind gradient, dropping it onto the ground heavily. The left undercarriage leg was bent. Upon taxiing back to the hangar the left leg failed completely and the aircraft came to a stop. It was reported after the event from ground observers that the aircraft suffered a serious gust of wind at the time of landing that also upset other aircraft parked on the ground nearby. No further action required by RAAus.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: During dual flight training the instructor was to demonstrate a simulated engine failure at 100’. The take-off was normal and at 100’ they reduced the throttle to the idle position and set glide attitude, however they descended at a much faster rate than normal resulting in the aircraft bouncing on the RWY and the NW collapsing. Instructors are reminded to ensure the aircraft is managed carefully when maneuvers of this type are attempted. RAAus aircraft have significantly reduced inertia compared to heavier CASA registered aircraft.
25/10/2018	OCC1542	Maitland Airport	NSW	Brumby	LSA R600	Jabiru	J3300	OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: During 100 hourly inspection cracks and a split under...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: During 100 hourly inspection cracks and a split undercarriage bulkheads were found. On further inspection and removal of underwing skins on LHS found a very poor repair of earlier damage from prior to current owner. This aircraft sustained damage to this exact area at 91 TTIS, it was repaired at the Brumby factory and returned to service. Unable to determine the cause of this current damage however appears consistent with a hard landing. Repairs carried out by a qualified LAME In accordance with the instruction and repair scheme from the factory.
25/10/2018	OCC1514	Bankstown Aerodrome	NSW	Aeroprakt	A22LS Foxbat	Rotax	912 ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: Previous radio issues with aircraft. The radio cables/antenna...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: Previous radio issues with aircraft. The radio cables/antennas have been replaced and needed to be checked. This particular flight was a circuits lesson with a student. All transmissions were normal and standard until the fourth circuit where we were not receiving any transmissions from tower. Troubleshooting was attempted with no sucess. The tower gave the green light for the landing as no radio contact was able to be made.
23/10/2018	OCC1511	Bankstown Aerodrome	NSW	BRM Aero	Bristell FG	Rotax	912 ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: During dual flight training short field take off from RWY 11L...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: During dual flight training short field take off from RWY 11L was conducted. During the climb passing 300ft, the aircraft lost power and could not climb anymore. As a result, the instructor took over controls from student and commenced an early turn onto crosswind due to lack of forced landing fields to the east of YSBK. The early turn led them straight into the helicopter circuit at low level. One helicopter traffic on crosswind was identified and the instructor planned to maintain separation. After completion of the turn onto crosswind low level, the Tower called to ascertain if ops were normal and the instructor informed them about the loss of power and urgency to return to land. On downwind, another helicopter was on finals for helipad and the instructor turned to the right to avoid it. The aircraft was unable to climb and maintained 400ft on downwind. Then landed RWY 11L without further incident. OUTCOME: Potential cause is vaporisation of the fuel due to heat under the cowl and radiating from the tarmac surface.
21/10/2018	OCC1513	Hughenden	QLD	Zenith Aircraft	Zodiac 601	Rotax	912UL	OCCURRENCE DETAILS SUBMITTED TO RAAUS: During flight a change in engine tone was noted and a distinc...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: During flight a change in engine tone was noted and a distinct odour of exhaust fumes in the cockpit detected and was getting stronger. The pilot proceeded to perform an uneventful precautionary landing on a gravel road. An inspection of the custom made mild steel exhaust revealed that the weld fixing the tail pipe to the muffler had failed in an area which had been wrapped in heat wrap and this is believed to have caused hydrogen embrittlement weakening the area causing it to fail.
16/10/2018	OCC1512	Roma	QLD	Allegro	2000	Rotax	912 ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: The aircraft was taken for a test flight of one circu...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: The aircraft was taken for a test flight of one circuit which was fine in the early part of the flight but as the speed built up on downwind, a loud bang was both heard and felt in the lower part of the fuselage. Speed was reduced and the aircraft landed without incident. The fuel tank breather was found to be clear and the seat appeared to be secured but the flap circuit breaker was found to be tripped even though the flaps had not been used during the flight. A close inspection was made of the aircraft and the reason for both the loud bang and the flap circuit breaker tripping. It was found that the lower flap motor mounting point was set into the fuselage of the aircraft skin. This is an area that has no structural members to support the flap motor. It would appear that the airflow over the flaps at cruise speed distort the alignment of the flap jacking screw with the motor housing and this moves the micro switch bar away from the positioning cam. As a result, the flap motor had actuated and run to the end of the thread on the jack screw to cause the motor to stall and trip the circuit breaker. There is a 100 x 100mm section on the lower fuselage where the flap motor is attached that moves up and down with both airflow and flap actuation.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: As the aircraft touched down on the grass RWY it drifted to the left slightly. The tailwheel was not quite on the ground, when the port mainwheel ran over a sprinkler depression and the aircraft suddenly nosed over smashing the propeller and skidding to a stop on the lower front of the engine cowl.
11/10/2018	OCC1561	Tyabb Aerodrome	VIC	Aeroprakt	A22LS Foxbat	Rotax	912 ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: Shortly after takeoff, the Instructor noticed high coolant an...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: Shortly after takeoff, the Instructor noticed high coolant and oil temperatures coupled with rough running while on downwind. An immediate safe landing was made. Pulled the oil dipstick but was to hot to handle. It was then noticed that traces of coolant were evident on the nose wheel fairing and inside the cowl. Investigation found the coolant hose had come off the intake pipe. RAAus AN270810-1 is applicable. The notice recommends cooling hoses are inspected on a regular basis including at the daily inspection. An article on coolant hoses has also been included in the Licence to Learn February 2020 edition.
