OCCURRENCE DETAILS SUBMITTED TO RAAUS: The incident aircraft was being ferried from YMRI to YBOA via YEML and YDAY. The aircraft had been purchased the week prior to the incident. The buyer had been taken for a flight in the aircraft by the seller, and a pre-purchase inspection had been conducted by an RAAus L2 maintainer and it had not been flown since the condition report. The departure from YMRI was uneventful, as was the climb to planned cruising altitude of 6500 ft. Approx. 85 nm into the first leg the aircraft suddenly began to vibrate. The throttle was immediately retarded to idle but the nature of the vibration didn't change. RPM was increased to cruise setting while the pilots considered their options. The vibration was very noticeable but was not severe, and there were no changes to the readings of any of the engine gauges or to the performance of the aircraft. The pilots assessed alternative landing options (YDYS and YMMU were the closest) but both these ALAs were owned and operated by mining companies and there were restrictions on their use. Also the status of the ALAs was unknown to the pilots so the decision was made to continue towards YEML. At that point (51 nm from YEML) the propeller departed the aircraft. The aircraft was immediately turned towards YMMU and a mayday was declared on the area frequency. Initially it looked like a glide to YMMU was possible but marginal. There was scrub between the aircraft and the end of the runway so rather than risk an undershoot into poor terrain the PIC elected to land in a paddock, with a farm track/driveway identified as an alternative option if the paddock was unsuitable. The non-flying pilot identified obstacles in the paddock and so the aircraft was manoeuvred to land on the farm track. The landing was relatively uneventful apart from the undercarriage running over a rut which made a loud noise but did not cause any obvious damage. CENSAR was contacted immediately after landing to cancel the mayday and advise that both occupants were safe and that the aircraft had not sustained further damage other than what was caused by the departing propeller.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: During a pre-fight inspection the L2 maintainer noticed during the elevator trim cable had lost tension and was laying on the floor of the fuselage. This prompted them to further investigate and try to understand why the cable had lost tension. With the aid of a flight instructor the trim tab mechanism was operated electrically from within the cockpit to its maximum positions on the in-cockpit indicator. During the operation in the up direction and as the trim tab got closer to its upper position a series of creaking sounds could be heard coming from the rear of the airframe. These noises focused the attention of the L2 maintainer towards the elevator trim tab. The trim tab was again operated electrically through its cycle of up and down, it was quickly identified that the trim tab was not freely moving (binding) and was not returning to its straight and level position when the cable tension was released The aircraft was immediately grounded and the elevator trim tab removed to try and identify the causes for the rotational resistance.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The holder of a recently issued Pilot Certificate holder was completing flying to build up pilot in command time towards a passenger endorsement. During the take-off roll the aircraft veered left. The pilot, responded with a primacy based on driving a car and applied the "clutch" resulting in application of more left rudder and the aircraft exited the runway. It completed a 360 rotation and came to rest in a ditch to the side of the runway. The aircraft was substantially damaged but the pilot was not injured. Following the incident the pilot has undergone further flight training as well as completing their Cross Country endorsement. The CFI has reviewed their processes and added additional procedures to help mitigate the risk of a similar incident occurring in the future.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot was operating a recently purchased Paradise aircraft into an airfield he had flown into before and he assumed the CTAF frequency was unchanged. Two training aircraft were in operation on runway 28 and the pilot of the Paradise aircraft conducted orbits at circuit height on the base leg of runway 28. As the pilot was on the incorrect frequency, multiple attempts by the pilots of both other aircraft in the circuit to contact the Paradise were unsuccessful. The Paradise proceeded to join the for runway 10 circuit as the windsock was not strongly indicating a specific direction. This resulted in the Paradise and another aircraft in the circuit both on final approach for opposing runways (28/10). Both aircraft operating on runway 28 took evasive action to prevent a near collision. RAAus spoke to the Paradise pilot (who recently completed a BFR) and confirmed the CFI had revised this information with him and he will never assume any information about airports or frequencies into the future. RAAus recommended the pilot review the CASA Visual Flight Rules Guide for latest circuit procedures and to monitor area frequency when not in the vicinity of an airport, as his previous practice had been to monitor 126.7.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The reporter was conducting training with a student in a VH aircraft. Whilst in the circuit they observed 3 other aircraft also conducting circuit training on runway 24, one of which was a Eurofox. The lesson they were conducting had been going for approx. 30 minutes when the Eurofox chose to start conducting conflicting crosswind circuits on runway 30. At the time the Eurofox decided to do this there were still 3 aircraft conducting circuits off runway 24. Due to runway 30 being right hand circuits and runway 24 being left hand circuits this presented a collision risk, particularly where both aircraft would turn base on their respective runways. RAAus is working with the pilot of the Eurofox to determine alternate means of completion of cross wind circuits at a busy airport.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: After a satisfactory training check ride covering slight crosswinds before third solo, the student then carried out two satisfactory circuits solo. During the course of the third circuit a 7-8 Kt unexpected cross wind gust on touchdown caused the aeroplane to veer to the left side of the runway and run onto the grass section of runway strip. Due to the recent heavy rain the aircraft became bogged and suffered no apparent damage.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The last flight before the due annual inspection the owner noticed the flap position indicator was intermittent and showed variations in the display. Upon inspection they found a slightly corroded joining connector at the flap motor in the tail plane, this was corrected by a certified aircraft electrician. A few days later the owner decided to check the entire flap loom. They performed a thorough inspection of every inch and used an inspection camera in the hidden places. On the screen they saw the main loom was laying 90 degrees to a small strengthening bracket and the loom was almost severed so they activated the master and gently rattled the wiring loom to see what happened, again the indicator light malfunctioned but this time the flap trim went into FULL nose down then popped the circuit breaker. The owner tried this again several times with an accomplice, it continued to go full down and then pop the circuit they then requested the aircraft electrician returned to repair the cable. The main battery cable was also chaffed but not enough cause a problem. Both cables are in sheaths now.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: After an inflight engine shut down, upon restart the engine ran roughly. The aircraft landed and the RH carby was flooding/leaking fuel out the overflow. The problem was identified as a missing idle return spring on the LH carby. The reporter suspects the idle return spring was shaken loose during the shutdown engine shaking.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft departed from Childers for a fuel consumption flight test. During the flight engine stopped completely, it had sufficient fuel aboard. The pilot tried to restart it three times in flight. The pilot chose a paddock for landing, they had to avoid power lines and flew under these, resulting in a dive which was recovered. The aircraft starboard undercarriage leg collided with a fence line, resulting in the aircraft impacting sideways, collapsing the starboard side undercarriage, tearing starboard wing and engine off.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft began to lose power, despite application of full throttle. Pilot who is also the owner and builder suspected overheating of the engine. The pilot completed a successful forced landing with no damage to aircraft or property. OUTCOME: The aircraft engine has been inspected and re-installed with a plenum to help increase airflow over the cylinders and keep engine within the required temperature range.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot was undertaking a Touch & Go at Northam during which they commenced the pre take off checks during the landing rollout too soon and at a higher speed than recommended. Whilst their vision was inside the aircraft they ran off the runway to the left and the LH main undercarriage leg was damaged (delamination). The pilot corrected and braked heavily to control the R-LOC. Subsequent inspection revealed the RH leg to also have a small delamination crack forming. The pilot has undertaken further remedial training with a RAAus CFI

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Complete loss of engine power at approx. 2300 feet. The pilot tried briefly to restart the engine without success, all gauges where normal before the failure with plenty of fuel on board. Aircraft was above heavily timbered terrain and the pilot tried gliding to the nearest opening but was not successful. OUTCOME: No injuries to pilot or passenger. Airframe damaged beyond repair. Engine removed and sent to L2 for examination which identified a snapped valve in cylinder number 3.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: On inspection during 100 hourly it was noted that the L/H rudder cable empennage area pulley was not rotating with rudder movement. The pulley was removed and found with 1.4 mm wear to aluminium pulley surface from cable movement. The cable was inspected serviceable and pulley replaced. Details of this occurrence have been sent to the manufacturer for review. Members are reminded of the importance of conducting thorough inspections during maintenance to ensure any defects are identified.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Port undercarriage axle crack caused failure leading to ground loop late stage of landing roll. This is not a common fault with this aircraft type. It is probable that the aircraft has had a heavy landing at some point and the cracked axle had gone unnoticed until it failed.
