OCCURRENCE DETAILS SUBMITTED TO RAAUS: On climb out at around 800 ft there was a loud bang and the windscreen departed the aircraft.
29/6/2023	OCC3331	Goulburn Aerodrome	NSW	Skyfox Aviation	CA25N Gazelle	Rotax	912A	OCCURRENCE DETAILS SUBMITTED TO RAAUS: Two aircraft were operating in circuit on RWY 22 at Goulburn ...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: Two aircraft were operating in circuit on RWY 22 at Goulburn AD, both were dual training flights from different flight schools. Both were aware of each others positions and intentions but due to circuit spacing and performance differences the departing Cessna on downwind and the Gazelle turning base came into conflict requiring evasive action by the RAAus Instructor. Both aircraft had lost situational awareness of each others position at the late downwind - base intersection point. An additional factor was the lower cloud base that precluded a separating climb by the departing aircraft. Alerted See and Avoid is a dynamic discipline that requires active monitoring and mapping by pilots to determine risk and apply appropriate management of threats. Extending a circuit leg, departing via another quadrant and speaking up if there is any uncertainty, can all add to the effective resolution of threats and near misses such as these. RAAus urge all pilots and particularly Instructors to focus on these fundamental disciplines to assist in avoiding catastrophic outcomes that are most likely where these situations develop into inflight collision.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT - with reference to Aeroprakt SB A32-15 and concurrent with Rotax 5 year hose change, removed oil return line noted to be heat damaged and with only slight bending cracked open. Hose was original fitment from manufacturer (aircraft 5 years old/400-hour TTIS). The Oil hose is not the hose as listed in the Rotax installation documentation. _PN956394. Hose kit supplied from AU distributor for the 5 year hose change also supplied with the same non-compliant hose. SB A32-15 clearly says to use the Rotax hose PN956394. Maintainer contacted AU Aeroprakt distributor who also confirmed all their stock of 5year hose change kits have the incorrect oil hoses. Defect report raised to highlight potential of some aircraft may have been fitted with incorrect P/N oil hoses.

After executing a good landing, on applying the toe brakes the pilot may have put more pressure on the left brake and due to the lateral limitations of the runway they were unable to recover before the nose wheel was on the grass and unable to correct the direction. The aircraft went over the verge and ended up in the cane field on the side of the airstrip.
25/6/2023	OCC3322	Echuca Aerodrome	VIC	Ekolot	Topaz KR-030	Rotax	912 iS2 Sport	OCCURRENCE DETAILS SUBMITTED TO RAAUS: During flight training, for a crosswind landing in gusty cond...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: During flight training, for a crosswind landing in gusty conditions. The aircraft experienced some sink, the student and Instructor did not go around and was too late to add power and landed hard. The Aircraft received a heavy landing inspection. Going forward the CFI/Instructor will be more vigilant when flying in testing conditions with students.
25/6/2023	OCC3323	Caboolture Aerodrome	QLD	Tecnam	P92 Eaglet G5	Rotax	P-112276	OCCURRENCE DETAILS SUBMITTED TO RAAUS: A student under supervision during solo circuit training had...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: A student under supervision during solo circuit training had completed 3 successful circuits with the last requiring a taxi back to the apron for a normal take-off. During the application of power the aircraft yawed left, and despite attempts reported by the pilot to correct, they were unable and when emergency stopping actions were applied the aircraft had already departed the runway area and impacted the boundary fence and surrounding trees. The aircraft received substantial damage but has undergone repairs. A subsequent flight assessment by the CFI identified deficiencies in yaw correction from stationary take offs and remedial training will be undertaken. Pilots are reminded that aircraft reactions to secondary effects of power are more pronounced in stop and go scenarios or stationary take-offs and control effectiveness may be limited in the initial take off phase. Progressive introduction of power and high levels of situational awareness and correctives actions where required need to be applied in these vulnerable phases of flight.
18/6/2023	OCC3317	Muchea/Greenside Aerodrome	WA	Vans	RV-3B	Lycoming	0320-E2D	OCCURRENCE DETAILS SUBMITTED TO RAAUS: During power reduction for approach engine surged in power an...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: During power reduction for approach engine surged in power and backfired, resulting in reduction of power and then stoppage. Due to low altitude the engine was unable to be restarted and the aircraft was unable to reach the runway, landing in trees/scrub approx. 100m short of the runway. At time of misfire engine parameters checked and fuel flow, temperatures and pressures checked and confirmed in operating range.
11/6/2023	OCC3306	Moonee Beach	NSW	BRM Aero	Bristell S-LSA	Rotax	912ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: Returning from a flight to YSGR and YPLI the aircraft was at ...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: Returning from a flight to YSGR and YPLI the aircraft was at 1000ft southbound over water, approx. 1nm from the beach, 5500rpm and 120ktas, all gauges were normal, no indication of any issues at all. Engine shuddered badly and the pilot pulled the throttle back to idle. The shuddering got worse and then the engine stopped with a loud clunk. No fire, no smoke. Garmin gave fault message for low oil pressure and low fuel pressure only after the engine stopped, on checking the log file there was no indication at all which leads the pilot to think it might be the gearbox. The engine can only turn around 90 degrees before stopping in each direction. The pilot decided to land on the beach as it was low tide and the sand looked wet and hard. They made a mayday call on the Coffs Harbour CTAF which was relayed to Brisbane by another pilot who was overhead Coffs Harbour at 4500 feet. They flew a gentle turn to set up for a downwind as the wind was from the Southwest. Once settled the pilot applied full flaps and turned final and landed without incident. They rolled out and steered up the slope to stay above the high tide mark. The pilot called off the Mayday and reported the safe landing, and again the pilot over Coffs Harbour relayed that to Brisbane.
8/6/2023	OCC3310	Redcliffe Aerodrome	QLD	Tecnam	P92 Echo Super DL	Rotax	912 ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot was conducting solo circuits to consolidate their f...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot was conducting solo circuits to consolidate their flying after renewing their certificate after an 11-year break from flying. There were multiple mixed operations in the circuit area at the time. It was assumed two identified aircraft were no threat and a take-off roll was commenced. As the aircraft lifted off and was beginning an initial climb the pilot heard the helicopter announce "ROLLING ". at this point, the pilot saw a dark-coloured helicopter rise above the black background of the tarmac some distance ahead of them. Avoiding action was taken by the pilot as well as a non standard radio call and collision avoided. The pilot then continued five more circuits before landing. This airport has high traffic levels and a variety of traffic including fixed and rotary wing, flight training, spraying , maintenance and private operations. Risk assumptions and target bias can lead to missing the biggest threats immediately before us, this is also known as selective attention and can increase risks especially in critical phases of flight. Alerted see and avoid and vigilance by pilots is a critical aspect of operations at non-controlled airports. Pilots are encouraged to watch the original visual presentation experiment on selective attention and the CASA Webinar series on Operations at Non- Controlled aerodromes as well as our safety series content; https://www.raa.asn.au/calendar-of-events/nationalsafetymonth/home/week-2-content/

OCCURRENCE DETAILS SUBMITTED TO RAAUS: On a dual instructional flight, the route was YRED -YKCY-YKRY-YRED. The student was diverted between YRED and YKCY to Conondale. The student was maintaining 2000ft on a diversion and making a decision as to proceed as the cloud base was 2500 over the ranges to Conondale. They then saw an Aircraft opposite direction appear out of nowhere, the instructor took control to avoid collision. The aircraft was at least 150-250 feet above them and passed overhead. Flight after that was uneventful rediverted to YCDR CPMN then YRED. Reminder to all pilots operating VFR to keep actively scanning the sky for other traffic or hazards.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot was performing autopilot tests using climb and descent VS/IAS settings, using the throttle to add and reduce power as necessary when they realised the throttle was not affecting the power setting yet still freely moving from full aft to full forward position, the engine RPM was stuck at 2440 RPM
1/6/2023	OCC3336	Caloundra	QLD	TL Ultralight	Sirius TL 3000	Rotax	912 ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot inadvertently entered controlled airspace to the So...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot inadvertently entered controlled airspace to the South East of YBSU (Sunshine Coast Airport). They made a simple error reading the map during the flight which lead to this infringement into controlled airspace. OUTCOME: Learning outcome achieved through member education relating to preflight planning including better understanding of map reading during flight.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: During a dual instructional flight, the aircraft was contacted by ATC, who advised they had strayed into YBSU controlled airspace (above the 2500' step). The instructor had allowed the candidate to fly too close to the control step and briefly enter Class D airspace, they were trying to give the student the opportunity to realise this and correct their error. After the ATC made contact the aircraft departed the airspace.
29/5/2023	OCC3285	Caboolture	QLD	Flight Design	CTSW	Rotax	912 ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: The fuel hose barbs fitted to the fuel gascolator and fuel t...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: The fuel hose barbs fitted to the fuel gascolator and fuel tap fittings are not the appropriate size for the fuel hose used. Cause - The fuel hose has been stretched and forced to fit the oversized barbs. The effect is a significant reduction of the thickness of the fuel hose and damage to the integrity of the hose. It is likely that eventually, the damaged hose could split at the point where it has been overstretched. On the CTSW, such overstretching of the fuel hose has been observed behind the dashboard, close to electrical wiring. On the CT, this is also the location of the fuel filter subject to a 2009 issued SB CTSW-06 / CT2k-04 / CTLS-01 that, on this aircraft, had not been carried out.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: At the conclusion of a trial instructional flight, the CFI and student returned to the airfield and conducted a circuit and final approach to the west on the downhill sloping runway. The stronger NW upper level winds indicated this was the preferred into wind landing option. Normal procedures at this location favour an uphill landing even with a surface tailwind as due to local topography, rotor turbulence and associated wind shear and sink are often prevalent in the circuit area. The Instructor chose to land into the identified wind and while conducting a low base to final turn experienced strong sink and wind shear and the microlight stalled and despite power being applied late in the landing to reduce sink rate, a heavy impact resulted. The CFI received minor injuries in the impact and the student was uninjured. The aircraft was substantially damaged. Surrounding topography can have substantial affects on the nature and degree of turbulence that can be experienced close to the ground. Local knowledge and significant experience can mitigate these effects, but conditions can vary in the specific locations in the vicinity of the landing zone based on a range of meteorological factors.
