10/9/2016	OCC0747	Archerfield	QLD	The Airplane Factory	Sling 2	Rotax	912 IS	Climbing out of RWY 28L the pilot made a left turn to join the circuit but when they went to reduce ...
Climbing out of RWY 28L the pilot made a left turn to join the circuit but when they went to reduce the throttle at the top of the climb it would not come back. The pilot immediately requested a climb to 1500ft overhead the field to try and fix the problem. After several attempts the pilot managed to pull the throttle back but felt something break when they did. Before descent the pilot performed some checks to make sure that they had full and free operation of the engine throttle before attempting to land. Once the pilot was satisfied, they reported ready for descent to ATC and made a faster than usual flapless approach to the runway to ensure they had enough speed and height in the event the throttle suffered another malfunction. The aircraft landed safely and there was no further reported issues. OUTCOME: Its was identified that the primary cause was resultant of a screw clamp holding the air filter box to the manifold intake not being done up tight enough during a 100 hour service. This led to it disconnecting and the throttle being caught on it. Maintenance has been completed and this issues has been rectified.

Birdstrike: On final circuit, a masked lapwing (Vanellus miles) flew up from the grass during holdoff phase prior to touchdown and was struck by either the left wing or left undercarriage. The aircraft was undamaged but the birds health is unknown. OUTCOME: This aerodrome has a high rate of bird strikes reported which is noted in the ERSA. Members are reminded that it is currently the start of the mating seasons and birds may display territorial behaviour to aerial predators.

Tracking north from Boonah a loss of power was noticed, the oil pressure light came on and the pressure gauge fell to zero. A suitable landing area was selected, and commenced approach, the engine had stopped with the propellor horizontal a hurried radio call was made with no response. The landing was OK on wet ground, the aircraft travelled about 150m when the nose wheel bogged at slow speed bringing the aircraft to a halt. OUTCOME: ATSB have conducted a short investigation into this incident. On 11 September 2016, at about 1000 Eastern Standard Time, a Jabiru SP500 aircraft registered 19-5503, departed Caboolture Airfield, Queensland (Qld), for a flight to Boonah Airfield, Qld. The pilot was the only person on board. As the aircraft approached Boonah Airfield, the pilot observed large white crosses on the runway indicating the airfield was closed. The pilot elected to return to Caboolture and applied engine power to climb to cruise altitude. At about 1055, the aircraft climbed to the north of Boonah. At a height of about 1,000 ft above ground level, the pilot noticed the engine RPM reducing and applied full throttle. At the same time, the pilot observed a low and fluctuating engine oil pressure indication. Within seconds, the engine failed and the propeller stopped rotating. The pilot identified a paddock to the north of their position as suitable for a forced landing. They manoeuvred the aircraft to conduct a forced landing into the paddock. The pilot ensured that turns made during the forced landing were not tight and of low bank angle to avoid an aerodynamic stall. Late in the ground roll, the nose wheel dug into the soft surface, the aircraft tipped onto its nose and the right wingtip struck the ground. The aircraft then stopped and settled onto its wheels. The pilot was not injured and the aircraft sustained minor damage. This incident is a good example of the effect an in-flight engine failure at a low altitude has on the time available to manage that failure and identify a suitable forced landing area.

7/9/2016	OCC0760	Yarram	VIC	Jabiru	J170	Jabiru	2200	The ATSB investigated a fatal aircraft accident involving a Jabiru J170, registration 24-5215, at Ya...
The ATSB investigated a fatal aircraft accident involving a Jabiru J170, registration 24-5215, at Yarram Airfield, Victoria at 15.44 EST Wednesday 7 September. It was reported that the aircraft collided with terrain while the pilot was conducting circuits. The pilot was the only person on board the aircraft. The ATSB deployed three investigators to the site. The ATSB found that the aircraft was likely subject to mechanical turbulence at the threshold of runway 09 at Yarram aerodrome. Trees and hangars on the north-eastern perimeter of the aerodrome were known locally to cause turbulence in the last 50 ft of the approach when the wind gusted out of the east-northeast. This information was not published in the Airservices Australia En Route Supplement Australia entry for Yarram aerodrome. The pilot was also likely affected by physical and mental fatigue given their age, medical history and recent physical labour. Fatigue’s effect on attention, reaction time, and vigilance likely exacerbated the pilot’s mishandling of the landing attempt and the subsequent go-around. The completed report pertaining to this accident is available on the ATSB website at https://www.atsb.gov.au/publications/investigation_reports/2016/aair/ao-2016-112/

OCCURRENCE DETAILS SUBMITTED TO RAAUS: During scheduled maintenance excessive play was noticed on the port flap. This, with pressure, enabled a movement of 3/8" at the trailing edge. On investigation the holes in the flap tubes, under the pilots floor, were found elongated slightly allowing the movement in the flap tube joint. OUTCOME: Appropriate maintenance and servicing has been carried out. Works were completed by LAME/L2 on LSA Sling 2. The Australian agent has been made aware of the potential issue and will monitor.

On landing there was a strong gusty Northerly wind. When the aircraft was approximately one meter off the ground a strong gust of wind hit the nose of the aircraft which caused the nose of the aircraft to rise and, on correction, the aircraft nose dived into the ground and somersaulted to land on the roof. OUTCOME: Pilot was competent and experienced in aircraft operation and aware of conditions at the time of the incident and correctly applied appropriate landing technique based on the situation. Whilst completing the landing roll, and "pinning" the tail wheel, a severe gust caused the aircraft to pitch and become airborne finally inverting on impact. The aircraft was destroyed however no injuries were sustained. High lift, lightweight recreational tail wheel aircraft that are often used for off airport operations. These aircraft are more susceptible to thermic turbulence and wind gusts during take off, and particularly landing, and require appropriate decision making regarding operation and use during these conditions.
29/8/2016	OCC0745	Caboolture	QLD	Bantam	Bs	Rotax	582	While descending to the dead side from 2000 ft to finally join crosswind on RWY12, and some where ab...
While descending to the dead side from 2000 ft to finally join crosswind on RWY12, and some where above RWY06 the pilot noticed a bird attacking what looked like a blue plastic bag (not uncommon sighting due to location of airfield to the tip). The bird and bag/ paper were making strange movements and the pilots thought that it could have possibly been a drone. The pilot lost sight of the bag and bird and landed safely. This possible drone sighting was mentioned at a later date to the local CFI and a student and the student confirmed that there had indeed been a drone flown over the hangers on that date that was playing with a bird. The pilot determined that the drone was about 1200 ft to 1000ft above RWY06 with no drone activity scheduled for the airfield. OUTCOME: This information has been reported to CASA in the interests of air safety and interference of drones with RAAus aircraft will continue to be monitored. Local area signage and procedures is recommended to ensure air operations do not conflict.
27/8/2016	OCC0740	Watts Bridge	QLD	Edra	Super Petrel LS	Rotax	912 ULS	Pilot experienced a radio communications failure after take-off from Watts Bridge fly in. Receiving ...
Pilot experienced a radio communications failure after take-off from Watts Bridge fly in. Receiving communication from other traffic was very weak and scratchy however the pilot maintained planned outbound track and climb to 2500 feet. The pilot attempted to resolve the issue by using alternative headsets and jacks and squawked 7600 to contact Brisbane Ctr 125.7 to advise other aircraft of the radio issue. The pilot revised their track to remain OCTA and divert around Archerfield CTR. The pilot broadcast twice more to Brisbane advising of other minor track and height changes and landed at Heckfield safely. OUTCOME: Operations has reviewed this report and have noted that the pilot carries a series of emergency procedures prompt cards to ensure that they follow the correct protocol. The cause of radio issues were unable to be identified however a future recommendation is to carry a back up hand held radio as a redundancy.
27/8/2016	OCC0753	Riddell Airfield	VIC	TOPAZ	KR 030	Rotax	UL	After a one hour local flight, when the pilot was on late final with 90 degree cross wind varying be...
After a one hour local flight, when the pilot was on late final with 90 degree cross wind varying between 10 and 15 kts. Approaching over the threshold at approximately 50 kts, nose into wind, the aircraft suddenly lost speed. The aircraft was then too slow to line up with the RWY. The aircraft landed heavily on the left main wheel cracking the leg. OUTCOME: Operations have reviewed the report. Pilot has conducted remedial training since the incident and suggested that in these conditions it would have been appropriate to have more speed on approach.
27/8/2016	OCC0739	Wollongong Regional Airport	NSW	Jabiru	J160C	Jabiru	22B	Aircraft was lined up for take-off on RWY26. As the pilot commenced the take-off run, the aircraft s...
Aircraft was lined up for take-off on RWY26. As the pilot commenced the take-off run, the aircraft started to veer to the left and the pilot over-corrected. The aircraft ran off the left side of the tar runway onto the grass, hit water pooled in the grass, then bounced up off a drainage channel. The aircraft then ran along a barbed-wire fence (on left of aircraft) until the aircraft went through the fence (where it made a right-angle bend). It then continued along the fence (now on right side of aircraft) until a fencepost tore the right wing-strut off the wing. The aircraft then dug the left wingtip into soft earth of the paddock, causing it to nose over and come to rest, inverted, on the barbed-wire fence, facing back in the opposite direction to the one it had been travelling. OUTCOME: The pilot lost control of the aircraft in the take off phase resulting in a runway excursion and collision with boundary fence. Contributing factors were incorrect take off technique, uneven runway surface and focus on defined external reference points during the take off roll. The pilot has been requested to undertake a full review with a RAAus Senior Flight Instructor prior to further command flight.

During circuit training with a student who required close attention, the downwind call for landing was missed resulting in the aircraft landing without clearance. OUTCOME: As a result of this incident it was agreed, after consultation with the Tower, that a Base call be made during circuit training to bring this into line with requirements for the parallel runway. This procedure will reduce the time between the call and landing and therefore reduce the possibility of missing the call due to time pressures.
26/8/2016	OCC0738	South Grafton Aerodrome	NSW	Morgan	Sierra	Jabiru	3300	After returning from a local flight to land on RWY08 the aircraft touched down on the bitumen after ...
After returning from a local flight to land on RWY08 the aircraft touched down on the bitumen after floating in ground effect for some distance. When the seal ends there is another 300 metres of grass and the aircraft continued onto the grass on the left hand side. There had been significant rain in the days prior and there was a very soft patch of ground. The nose wheel sank into the soft patch, the nose leg bent and the aircraft came to a halt. The aircraft crossed the fence at approximately 65 kts with more than 30 ft of altitude. The air was particularly buoyant and the aircraft seemed to float along forever however eventually ran out of energy. The pilot touched down on the main under carriage and had the nose wheel on the ground before the end of the bitumen. OUTCOME: Pilot approached too fast, and failed to recognise a potential runway overrun as a result of the increased approach speed. The aircraft overran the bitumen component of the runway, and the nose wheel subsequently dug into the grass component of the runway overrun area. As a result of recent rain, the grass was softer than expected and the nose wheel was bent. Pilot has noted future flights will ensure a go/no-go assessment is made and a go-around initiated early enough to prevent a recurrence.

Pilot had set up to land and was flaring before landing. As they pulled on the control stick (back to flare) the passenger's drink container cooler (located between his legs) restricted the stick from any backwards movement. The plane landed heavily on the nose wheel first then the pilot felt the tail hit the runway and the plane veered to the left of the runway. The pilot began to brake hard and steer back to the centre of the runway however the plane did not change course and continued into the trees. The left wing hit the trees and the aircraft went sideways and stopped. OUTCOME: Pilot was unable to correctly flare the aircraft during the landing phase due to the passenger retaining a small drinks container on his lap. Future operations will ensure an adequate passenger briefing is conducted and confirm that items are correctly stowed as part of pre-landing checks.
20/8/2016	OCC0743	Adelaide Soaring Club, Gawler	SA	Jabiru	J170C	Jabiru	2200B	The pilot (instructor) and student were taxiing out towards RWY23 whilst listening out on the radio ...
The pilot (instructor) and student were taxiing out towards RWY23 whilst listening out on the radio of where all circuit traffic was. There was a light 5-10 knot head wind towards RWY23 use. At the hold point, prior to crossing over the active runway, the pilot and student conducted a good visual lookout to ensure that no aircraft was on final (and that no one was having an emergency and doing a tail wind landing) and that no aircraft was about to take off. The pilot and student heard no radio call of any aircraft on final, no rolling call from the aircraft on the threshold and no threshold traffic was moving. The pilot made a radio call to taxi across the runway, as is procedure, and taxied across the runway. Almost across the runway, the pilot and student received a call from a tug and glider combo that they were rolling right behind their aircraft. Neither the pilot or student had heard any radio call and when they started crossing RWY23, the tug and glider were stationary. The pilot had sufficient separation and taxied out of the way and the two aircraft were airborne and behind and above them when the pilot was alerted that they had taken off. The pilot exchanged radio calls to the effect of maintaining sufficient separation. On returning to the ground after the flight, the pilot and student discovered from numerous sources that their taxiing crossing radio call came through however the rolling call did not and both aircraft had transmitted at the same time. Radio communication and situational awareness/good lookout prevented any incident. OUTCOME: The pilot of the Jabiru conducted usual lookout and radio call procedures, as did the glider/tug combination. Due to failed radio reception, the call from the glider/tug was not received, and the glider/tug combination did not observe the Jabiru crossing the runway. Pilots are reminded of the importance of alerted "see and avoid" and ensuring runways are clear in both directions, both on the ground and for approaches. OPERATIONAL GUIDANCE AT ADELAIDE SOARING CLUB: As aerodrome operator they have revised their operational guidance as follows: • Taxying aircraft intending to enter a runway must stop at the hold point and ensure that it is “all clear” before proceeding. • No glider tug shall be left parked on the “take-off pad”. • Pilots are to assume that if a tug is on the “take-off pad” that a glider launch is imminent. • When a tug is on the “take-off pad” any aircraft intending to enter the same RWY must make radio contact with the tug pilot to establish the status of the tug operation. The tug pilot will advise the aircraft intending to enter the runway if it is safe to do so.
17/8/2016	OCC0807	Moorabbin Airport	VIC	Jabiru	J-160C	Jabiru	2200	The pilot was issued instructions to join the circuit and follow a C172. The pilot turned and mistak...
The pilot was issued instructions to join the circuit and follow a C172. The pilot turned and mistakenly followed the wrong aircraft. When the error was detected the pilot was instructed to go around and rejoin the circuit on mid downwind. OUTCOME: While in a high traffic environment at Moorabbin, the pilot mistakenly followed the wrong aircraft. Once advised by the tower he conducted a go-around to avoid a possible mid air collisions. Pilots are reminded to remain vigilant in the circuit at all times to avoid possible conflict with other circuit traffic.
