The aircraft was on a training flight, which was its second flight of the day after purchase from its prior owner. The aircraft was pre-flight inspected and nothing of concern was noted. While taking off, as it left the ground the aircraft experienced significant yaws left and then right that didn't seem able to be corrected by rudder, so the engine power was cut and the aircraft was able to land on the airstrip without injury or crashing. When attempting to taxi back to the start of the runway, it was immediately discovered that there was no rudder control. The pilot and instructor alighted from the aircraft and saw that the rear strut had broken off in two places, leading to separation of the tail wheel assembly, which also provided support for the end of the rudder. Hence the rudder was not controllable. A repair scheme from a CASA certified welder was supplied for rectification.

During a touch-and-go landing, an aircraft was observed in close proximity of a parked glider on RWY 31. Outcome: There was a misunderstanding between the PIC and trainee. This resulted in the aircraft landing on the bitumen vice the left side strip. The PIC and trainee debriefed this issue at length. All pilots are reminded of the importance of clear and concise communication both during pre-flight planning and within the cockpit.
21/7/2017	OCC1106	Unknown	QLD	Tecnam	P2004 Bravo	Rotax	912ULS	During a routine 100hrly inspection/oil change, a substantial quantity of solid debris [crushed alum...
During a routine 100hrly inspection/oil change, a substantial quantity of solid debris [crushed aluminum in appearance] was found in the oil tank. The engine was removed and sent to the Rotax agent, where it was stripped and inspected. No sign of contaminant or damage was found. Only other way for debris to enter the oil tank, is through the oil filler cap. Determined Outcome: Nothing was found to be wrong with the engine. Owner has decided to re-evaluate hanger security, design some form of security for aircraft engine compartment, for when aircraft is left unattended at airfields. Owner claims this was a deliberate act of sabotage. Nothing further to be done by RAAus.

While completing a BFR flight the pilot was demonstrating a simulated engine failure glide approach. Due to a high sink rate the pilot intended to apply full power, however removed all power by mistake resulting in a heavy landing. The aircraft bounced and impacted on the nose gear, which collapsed resulting in the aircraft flipping over. OUTCOME: The pilot will complete his BFR prior to further flight. RAAus remind pilots who also operate farm machinery to carefully apply power due to the possibility of a reverse throttle input while under stress or pressure.
15/7/2017	OCC1099	Private Airfield, Indented head	VIC	Brumby	610	Rotax	912 ULS	The aircraft overran the end of the RWY and hit a fence. Outcome: The pilot identified the root c...
The aircraft overran the end of the RWY and hit a fence. Outcome: The pilot identified the root cause as incorrectly approaching this 600m ALA too fast resulting in excessively long landing phase. This coupled with reduced traction due to wet grass and limited landing distance remaining were also contributing factors. Appropriate remedial training was initiated by the pilot after this incident to ensure appropriate competencies for operations at this ALA.
12/7/2017	OCC1186	10nm N of Lilydale	VIC	Jabiru	J230D	Jabiru	3300A	Airspace infringement. The pilot was unaware they had entered CTA until advised later. The pilot is ...
Airspace infringement. The pilot was unaware they had entered CTA until advised later. The pilot is usually very conscious of the height restrictions and aware of the limits on the route as they fly it frequently. It is possible that it was a loss of concentration or as it was an unconfirmed altitude, transponder error. The pilot will have the transponder calibration checked. DETERMINED OUTCOME: While attempting to ensure accurate hemispherical levels were maintained the pilot penetrated the lower limit of a CTA step. Members are reminded they can significantly reduce the risk of inadvertent operation in CTA by ensuring careful flight planning is carried out prior to the flight and using known geographical features to ensure controlled airspace is avoided. Hemispherical levels are not mandatory below 5000' AMSL, however where possible pilots are encouraged to plan at these levels if operating below 5000' AMSL.
9/7/2017	OCC1094	Wagga Wagga	NSW	Jabiru	J230c	Jabiru	3300	During a local flight, at approx. 10m N of YSWG and 2000ft altitude engine started to run rough. Th...
During a local flight, at approx. 10m N of YSWG and 2000ft altitude engine started to run rough. The pilot made a mayday call on local frequency 126.95 to gain a clear track for entry to RWY23, when at 3m from YSWG the engine failed completely. The pilot then found a suitable paddock and executed an uneventful emergency landing. DETERMINED OUTCOME: RAAus Technical team have engaged with the owner and manufacturer to attempt to enable further investigation. Possible valve failure due to high EGT readings. At this stage RAAus cannot take any further action.
8/7/2017	OCC1162	Moruya	NSW	Aeroprakt	Foxbat A22LS	Rotax	912	OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: During taxi it was discovered that two of the four en...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: During taxi it was discovered that two of the four engine mounting bolts had become loose and fallen out. The engine was able to pivot around the remaining bolts and damaged the fibreglass cowling. DETERMINED OUTCOME: RAAus Technical Manager raised this issue through the Australian Foxbat agent. The factory have advised that they will amend future installations and replied that "to avoid such a problem we decided on all new aircraft apply paint marks of those bolts. For inspection of their condition" The supplier and factory would also like to reiterate that the AMM calls for 200 hour interval inspection of proper torque and the engine mount attachment bolts. The Foxbat Australia website can be view for further information on this issue.
6/7/2017	OCC1090	Camden airport	NSW	Jabiru	160C	Jabiru	2200	OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Prior to takeoff, a “full and free” control check was...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Prior to takeoff, a “full and free” control check was completed normally. During the takeoff roll, abnormally light back pressure was noticed on the control yoke and the takeoff immediately aborted. Inspection of the cable indicated that the flared mouth of the tubing, designed to retain the tube in the flexible housing while allowing some lateral movement, had been flattened, allowing the tube to disengage.

After take-off the pilot noticed the aircraft was not climbing as it should. They turned onto downwind leg at about 400ft despite full throttle, the thrust was not able to sustain level flight so the pilot elected to land on irrigation country as they could not return to the airstrip. The aircraft landed in a lettuce paddock which was hilled up, the axle of aircraft made contact with the hills and overturned the aircraft on landing. The pilot abandoned aircraft as fuel was pouring out and smoke evident. With the help of a farmer was able to right the aircraft and turn switches and fuel off. DETERMINE OUTCOME: On inspection of the engine it was identified that loose cylinder head bolts (finger tight) and a suspected damaged head gasket. It was suggested that the tappets were loose. L1 practical will help owner builders to become aware of process and controls during building and ongoing maintenance. This was a amateur built aircraft.

On touchdown for a students first solo flight the left tyre blew/was flat. The student used the break to keep straight on the otherwise uneventful landing. The aeroplane was taxied clear of all movement areas and tied down prior to last light awaiting repairs when staff available. Outcome: No investigation required by RAAus.
23/6/2017	OCC1086	Sunshine Coast Airport	QLD	Alpi Aviation	Pioneer 300	Rotax	912 ULS	The pilot departed YCDR and gave inbound call above the Ring Tank to YBSU. The pilot did not ensure ...
The pilot departed YCDR and gave inbound call above the Ring Tank to YBSU. The pilot did not ensure they were outside of controlled airspace whilst checking the radio and entered Class D airspace. Outcome: Pilot under training was provided additional guidance and training on enroute planning and task management while manoeuvring close to CTR boundaries. Primary cause was identified as Loss of situational awareness and task prioritisation in flight
23/6/2017	OCC1082	Narrabri Airport	NSW	Tecnam	P2002 Sierra	Rotax	912S ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Upon landing a strong petrol smell was investigated. ...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Upon landing a strong petrol smell was investigated. A large leak was discovered from the carburettor float bowl on cylinder 2 and 4 due to the float post coming out of the bowl leaving a hole. Outcome: Rotax have changed the floats for the carburetors due ongoing issues and it appears that this has rectified this issue.
