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.

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.

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.
