On approach into RWY08 in a Piper Seneca, a Jabiru rolled through the holding point while simultaneously giving a "crossing the runway" call. Piper pilot was about to touch down and could not Go-around (as the Jabiru was too close) and elected to continue to land and apply emergency braking. Piper pilot gave a call indicating their position which promoted the pilot to stop immediately. Piper stopped about 50 meters short of the Jabiru without having to avoid the Jabiru. OUTCOME: Ops spoke with JABpilot who agreed confusion may have existed between his intentions and his actions. Pilot didn't believe the risk of collision was high, however wasn't aware the Seneca had applied emergency braking to stop. JABPilot has spoken to local CFI and learnt several lessons including ensuring a situational picture of aircraft is built even while taxiing and running up, and ensuring clear comms are made.

Jabiru was holding ready to cross RWY08 and RWY26 and did not hear the base call for the VH aircraft on RWY08 however heard the on-final call for a full stop. The active runway at the time was RWY34 however there was a 5-10 kt wind from the East. The VH aircraft touched down and Jabiru pilot gave a call that he was taxing for RWY34 and cross RWY08 and RWY26. The VH aircraft called to state they were still on the runway which Jabiru had a clear view of and could see they were starting their turn off the runway. Jabiru pilot started to move when a call was heard from VH aircraft and pilot immediately stopped to assess the situation. The VH aircraft departed at the cross strip and radioed the runway was available and Jabiru Pilot acknowledged. OUTCOME: Ops spoke with JABpilot who agreed confusion may have existed between his intentions and his actions. Pilot didn't believe the risk of collision was high, however wasn't aware the Seneca had applied emergency braking to stop. JABPilot has spoken to local CFI and learnt several lessons including ensuring a situational picture of aircraft is built even while taxiing and running up, and ensuring clear comms are made.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Significant leakage of fuel under pressure along the length of the fuel line from pump to injector rail. Fuel forced out under pressure through the Stainless Steel over-braid. Aircraft has previously flown, during factory flight test however has not flown since then for 2 + years. Examination of a small length of core "rubber" hose from which over-braid had been removed showed a multitude of cracks and tears in the hose. Leakage estimated at 1 litre plus in 30 secs of pressurisation. OUTCOME: Tech reviewed report and appears that fuel line issues due to an extended storage period. Tech recommends a full inspection of aircraft after long storage periods to identify any corrosion that may have occurred.

Pilot was asked to join up wind at 1500 and instead turned for base. When told to maintain 1500 and track for upwind Pilot requested to join on final. The tower cleared pilot, after which he flew a slightly unstable approach and did not perform a good landing. The pilot kept the aircraft on the runway and taxied to the apron. OUTCOME: Operations has reviewed incident. CFI has conducted debrief with pilot for further education and training to provide appropriate information to the student. NFA required.

First take-off for 2 weeks aborted on ground run when engine ran rough - stopped and investigated but found no causes. Ran up engine and carried out ignition check at 4000 RPM. No problems and normal engine running on taxi back to take-off at end of strip. Second take-off normal with engine running at 5430 RPM on climb. At approximately 250-280 ft the engine ran rough and lost power. Pilot brought the throttle to idle and made off field normal landing straight ahead in wheat paddock 400 m north of end of RWY03. Permission gained from landowner to cut fence between paddock and end of RWY03. Aircraft pushed back to runway and taxied back to hangar. OUTCOME: Maintainer was unable to find a definitive cause of the rough engine however conducted the following after the incident: - drained all fuel (98 mogas) and replaced it with new fuel. - checked the gascolator and cleaned it. - removed carbs and cleaned with carb cleaner. - cleaned filter pods with K&N kit. - new plugs were ordered from manufacturer and installed. - checked lines, carb stubs and wiring attachments. Maintainer conducted a long run-up and checks with no issues with the test flight being OK and 1.5 h cross country being OK. It is recommended that a 50 h change would have be prudent with the plugs as the engine started easier and ran smoother after the plug change.

Pilot test flew aircraft after instillation of a new prop. After having no problem with taxiing around Pilot lined up and rolled on RWY 14. After remaining straight for 200m and up to 50kts, a whirring bang was heard under the port wing. The aircraft slewed to the left in spite of full right rudder, decelerated, the tail came up even with full back stick, then the prop struck and came to stop on the nose. OUTCOME: The KR2 is being rectified by the new owner of the aircraft who has been repairing it and fitting it with a Jabiru engine (as the original engine crankshaft was damaged in the accident) The owner/ maintainer indicated that the incident occurred due to the port disc brake assembly distorting at speed which tangled with the spat, causing the wheel lockup. Additionally it appears that the seat cushioning also hindered some up deflection. Owner/ maintainer is modifying the cushion to get full up elevator, rebuilding a more rigid brake assembly and will be adjusting the weight and balance after the engine refit to ensure that there is no nose heavy tendency.

Failure of fuel to feed from right hand wing to surge tank due to blockage in the vent. OUTCOME: The pilot/ maintainer inspected the engine and the breather/vent was cleaned out. The pilot/ maintainer waited for fuel to cross feed as the breather/vent was not operating correctly due to contamination. RAAus Technical review. This is a 19 amateur built - previous reports have identified that the fuel vent is susceptible to small particles and grit becoming lodged and then preventing the vent from working (for example, in coastal conditions, salt crystals have formed which has then prevented the vent from operating correctly). The inspection identified that there was no cross feeding and in removing and cleaning the fuel vent the pilot was able to continue on without any other further issues.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Right wing rear spar had no attachment and had nil support, this allowed over 1" of up & down movement at the trailing edge. LH wing had wedge bashed in to eliminate movement. Severe corrosion on bolts holding tail plane. OUTCOME: This is an amateur built aircraft. Maintenance errors will be addressed with training and the release of Technical Manual Issue 4. The L2 has rectified the current issue.
6/10/2015	OCC0453	Port Macquarie	NSW	Aeroprakt	A22 LS Foxbat	Rotax	912 U L S	The aircraft landed hard, resulting in a collapsed nose landing gear. OUTCOME: CFI followed up with...
The aircraft landed hard, resulting in a collapsed nose landing gear. OUTCOME: CFI followed up with pilot the control issues that occurred during this incident.
5/10/2015	OCC0467	Oakey	QLD	Austflight ULA	Drifter A-582	Rotax	582	The aircraft had been refuelled by Jerry-can and fuel drain carried out with no visible contaminatio...
The aircraft had been refuelled by Jerry-can and fuel drain carried out with no visible contamination. Departure was from a private strip and after traveling east to another private strip an approach was made from the west and a go around conducted, followed by an approach from the east, no attempt to land was made. On climb out to the West at approximately 300 feet AGL, the engine stopped. The aircraft was turned into wind and lined up with furrows in an open paddock, a brief attempt to restart was made during the turn. An uneventful landing was carried out. OUTCOME: Appropriate emergency actions were taken following engine failure to land aircraft safely. Appropriate fuel practices were carried out operationally. Aircraft is normally trailered at YBOK. The aircraft had been parked assembled outside one week earlier, Normal fuel drains were conducted pre-flight. Technical - Following the accident the carburettor bowls and fuel cells showed evidence of water that was not detected in the pre-flight. Complete fuel system was cleaned and flushed. The no1 cylinder showed signs of seizure and was repaired accordingly. A subsequent test flight was conducted and was successful and all engine operations normal. All pilots must ensure appropriate fuel sampling is conducted pre-flight based on the design of the fuel system and its likelihood to ingest water when secured in open environments. Poor sealing and open venting systems are common causes of water ingress in flight fuel systems.
4/10/2015	OCC0492	Cessnock	NSW	Tecnam	Sierra P2002JF	Rotax	912 S	OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Electric elevator trim runaway. During flight the Pil...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Electric elevator trim runaway. During flight the Pilot operated up-trim. After releasing the up-trim button (located on the head of the control stick) the aircraft continued to change attitude. The trim electric isolation switch was moved to 'off' and control was held with some effort. The stick trim selector was moved to the co-pilot and trim isolator set to 'on'. Retrim was possible by using the buttons on the co-pilot control stick. The fault was later found to be a faulty up-trim switch in the pilots stick. Both up and down switches were replaced and no further trouble has been identified. OUTCOME: Switch was identified as the problem with no actual loss of primary flight control.
