OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst conducting circuits at Bankstown on runway 29L, the Bristell was following a Sling which was marginally slower and performing wider circuits. Upon unsuccessfully attempting to create sufficient spacing Tower directed the Bristell to perform a go around. The go around was performed and attempts were made to climb and divert to the left side of runway 29L however the pilot did not divert enough to create sufficient spacing. The incident was reviewed by RAAus. The pilot correctly identified a need for improved situational awareness and decision making in the report. In the future this will include applying increased separation margins and making decisions earlier to avoid further occurrences.
1/12/2019	OCC1879	Albany regional Aerodrome	WA	Jabiru	J160	Jabiru	2.2	OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft lost power at 4000ft with the engine reduced to ...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft lost power at 4000ft with the engine reduced to idle (900 RPM). The option was taken to return to the airport. Carb heat was applied for icing and a forced landing procedure was enacted. A best L/D is achieved at 70kts. The runway became unachievable with a stronger wind of 15-20kts. The engine remained at idle till switches were cut at 200ft AGL. The undercarriage struck a fence with the aircraft at stall point resulting in the aircraft impacting the ground nose first however it did not become inverted. Likely cause of power loss was carburettor icing. Conditions were suitable for icing on the day.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft radio had failed completely so the pilot was using a borrowed a portable radio and while its interface with the aircraft was giving problems, it was usable when the pilot took off so the test flight was continued. The Sonex build plan recommends fuel level monitoring is conducted with a sight gauge located on the panel of the aircraft. The pilot believed this sight gauge was working properly as it appeared to be giving reasonably accurate indications of available fuel on previous flights. On take-off the sight gauge indicated that there was between a third and half of a tank of fuel. The pilot, distracted by the problems with the radio didn’t dip the fuel tank or crawl under the instrument panel to visually inspect the fuel level. When the aircraft was about 15 mins flight time NW of Bendigo, the engine started to lose power and eventually stopped completely. The pilot selected a forced landing site in a paddock and landed without any damage uneventfully. The pilot has provided proposed modifications to the fuel monitoring system to remove this issue. Best practice is to ensure the fuel tanks are physically dipped prior to flight to ensure fuel quantity.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The student was flying solo and it was the first solo without a check flight. The approach and flare appeared normal. The aircraft ballooned on touch down with a slight indication of a Pilot Induced Oscillation (PIO). After the second touchdown, the pilot initiated a go around and then proceeded to do 4 more circuits, all to an acceptable standard. On returning to the hangar, a distinct "nose down" attitude of the spinner/propeller was noticed resulting from the previous PIO. A detailed analysis of the aircraft characteristics and the student training was undertaken with the CFI to identify future opportunities to reduce risk of PIO related occurrences. Additional training will be undertaken prior to further command flight.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Microlight trike engine failure due to fuel starvation. Carried out a successful emergency landing on the northern side of South Stradbroke island. On inspection found the check valve (non return valve) on the end of the fuel pickup tube in the fuel tank to be blocked. The check valve was cleaned out and fuel tank inspected for contamination. An engine run was carried out to confirm serviceability. Aircraft was flown back to base. Outcome: Blockage of the fuel feed hose inside the tank. Attention needs to be paid to keeping the fuel tank debris free, fuel drain clear and bright during the pre flight may not indicate the presence of FOD in the tank. Continued discipline of only using clean drums and even filtering the fuel on the way in will prevent this type of occurrence.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst conducting a navigation exercise with intentions of a touch and go at Cowra Airport, the aircraft suffered an incredible amount of loss of power on take-off until unable to continue climbing (from 5200RPM to 4400RPM, which is below 60% of engine power). The instructor took control just below circuit height and levelled off for a full stop back on RWY 33. Fault finding identified vapor lock as the probable cause due to the high temperatures on the day.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft was cleared to taxi via Alpha 1, Juliet, Echo. The pilot was confused by signage and continued on Alpha 1 and unknowingly onto the runway centre and crossed the holding point without clearance. There was an aircraft on short final, the pilot slowed to allow it to pass and to keep it in sight. Tower instructed to hold position as the aircraft had entered the runway area. The pilot was then instructed to cross the runway. The occurrence was reviewed and future occurrences mitigated by the flight school implementing improved training procedures for trainee pilots on surface movement requirements..

OCCURRENCE DETAILS SUBMITTED TO RAAUS: On initial leg of R15 impacted eagle/hawk about 1.7m from left wing root. The aeroplane has been initially inspected by a level 2 maintainer who advises that further investigation is required prior to any further flight. RAAus continues to gather statistical data on birds and wildlife that interfere with aviation activities around the country. It is particularly important that these incidents are reported so that RAAus can identify problematic areas and notify the relevant parties.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: A student was on a solo navigation flight. When departing on downwind, thermals caused by the heat resulted in the aircraft increasing in altitude. The student attempted to arrest the climb but was unable to manage the situation, ending up at 2000 ft. The instructor had discussed with the student outbound and inbound altitudes with the student before departing. On return from the flight a full debrief was conducted with a discussion about how to manage height control in addition to possible communication strategies for ATC regarding block height and amended height requests.
18/11/2019	OCC1866	Barwon Heads Aerodrome	VIC	Brumby	LSA R610	Rotax	912 ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: An RAAus registered aircraft that was uncontactable on radio ...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: An RAAus registered aircraft that was uncontactable on radio via Barwon Heads CTAF and Melbourne Centre when it flew near to skydivers in a drop zone. The pilot was interviewed by RAAus and it was determined some confusion about the correct frequencies and procedures existed. The pilot completed a ground review with a RAAus Pilot Examiner and has now adopted improved procedures to ensure adequate separation from parachute aircraft and parachutists. RAAus pilots are reminded to ensure they reference appropriate charts for the proposed flight area to confirm radio frequencies and comply with procedures at uncontrolled aerodrome as per Civil Aviation regulation (CAR) 166 and guidance material provided in the latest version of Civil Aviation Advisory Publication (CAAP) 166.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Climbing out, normally get 3000 RPM, got to 300', got a rev drop, confirmed with the tcho 2800 rpm, over trees away from the strip, turned around to return to the strip, got to gliding distance, back to idle, lots of vibration, applied a small amount of power to remove engine vibration, landed safely, no injury to people, no damage to aircraft. Subsequent investigation revealed part of the side of the #4 piston had a piece missing, top ring damaged, area between 1 and 2 ring damaged.
17/11/2019	OCC1868	Ayr Aerodrome	QLD	Jabiru	J170C	Jabiru	2200B	OCCURRENCE DETAILS SUBMITTED TO RAAUS: During dual flight training, on climb out after take-off from...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: During dual flight training, on climb out after take-off from Ayr aerodrome there was a loud thump noise with a sudden loss of power. The instructor immediately took over control and turned the aircraft towards the aerodrome hoping to make a landing on RWY 11. Despite having a tailwind at that point the glide was not progressing as well as expected, so the instructor repositioned the aircraft for an approach to an obstacle free headland between two recently harvested sugar cane blocks. The aircraft landed on the headland without any damage.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft made contact with power lines resulting in collision with terrain and serious injury to the pilot
16/11/2019	OCC1864	Goulburn Aerodrome	NSW	Skyfox	CA25N Gazelle	Rotax	912A	OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft was returning to the airfield after a dual train...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft was returning to the airfield after a dual training flight. During the cruise, the aircraft began vibrating abruptly and aggressively. The instructor immediately took back control and began to troubleshoot the issue. During this time, the engine RPM was fluctuating but more-or-less stable and in the vicinity of its normal cruise setting. Troubleshooting confirmed that the issue was engine related, during which the instructor also confirmed the aircraft had either full power with no vibration, or low and decreasing power with considerable vibration. The instructor opted to maintain height and full power and continue tracking towards Goulburn and also commenced a standard forced landing drill, preparing the aircraft, cabin and student for any deterioration that would require such a landing. During the flight back the situation deteriorated with power decreasing to idle with significant vibration and backfiring before spiking back to full power and repeating this pattern several times. As a result, the instructor declared a PAN PAN on the CTAF frequency (127.150) primarily to let other aircraft operating within the area know the situation and the intention of continuing towards the airport as a priority. During the approach and descent, the engine at full power and the instructor planned to make a gradual descent towards RWY 22 at high speed and shut the engine down shortly before touchdown, trading airspeed for altitude as necessary. The aircraft landed uneventfully. The aircraft was pushed back to the hangar, and inspection revealed that the left throttle control cable had snapped.
