OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst conducting a check ride, the approach airspeed decayed to 50kts in gusty conditions and the aircraft was caught by a wind gradient, dropping it onto the ground heavily. The left undercarriage leg was bent. Upon taxiing back to the hangar the left leg failed completely and the aircraft came to a stop. It was reported after the event from ground observers that the aircraft suffered a serious gust of wind at the time of landing that also upset other aircraft parked on the ground nearby. No further action required by RAAus.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: During dual flight training the instructor was to demonstrate a simulated engine failure at 100’. The take-off was normal and at 100’ they reduced the throttle to the idle position and set glide attitude, however they descended at a much faster rate than normal resulting in the aircraft bouncing on the RWY and the NW collapsing. Instructors are reminded to ensure the aircraft is managed carefully when maneuvers of this type are attempted. RAAus aircraft have significantly reduced inertia compared to heavier CASA registered aircraft.
25/10/2018	OCC1542	Maitland Airport	NSW	Brumby	LSA R600	Jabiru	J3300	OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: During 100 hourly inspection cracks and a split under...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: During 100 hourly inspection cracks and a split undercarriage bulkheads were found. On further inspection and removal of underwing skins on LHS found a very poor repair of earlier damage from prior to current owner. This aircraft sustained damage to this exact area at 91 TTIS, it was repaired at the Brumby factory and returned to service. Unable to determine the cause of this current damage however appears consistent with a hard landing. Repairs carried out by a qualified LAME In accordance with the instruction and repair scheme from the factory.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Previous radio issues with aircraft. The radio cables/antennas have been replaced and needed to be checked. This particular flight was a circuits lesson with a student. All transmissions were normal and standard until the fourth circuit where we were not receiving any transmissions from tower. Troubleshooting was attempted with no sucess. The tower gave the green light for the landing as no radio contact was able to be made.
23/10/2018	OCC1511	Bankstown Aerodrome	NSW	BRM Aero	Bristell FG	Rotax	912 ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: During dual flight training short field take off from RWY 11L...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: During dual flight training short field take off from RWY 11L was conducted. During the climb passing 300ft, the aircraft lost power and could not climb anymore. As a result, the instructor took over controls from student and commenced an early turn onto crosswind due to lack of forced landing fields to the east of YSBK. The early turn led them straight into the helicopter circuit at low level. One helicopter traffic on crosswind was identified and the instructor planned to maintain separation. After completion of the turn onto crosswind low level, the Tower called to ascertain if ops were normal and the instructor informed them about the loss of power and urgency to return to land. On downwind, another helicopter was on finals for helipad and the instructor turned to the right to avoid it. The aircraft was unable to climb and maintained 400ft on downwind. Then landed RWY 11L without further incident. OUTCOME: Potential cause is vaporisation of the fuel due to heat under the cowl and radiating from the tarmac surface.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: During flight a change in engine tone was noted and a distinct odour of exhaust fumes in the cockpit detected and was getting stronger. The pilot proceeded to perform an uneventful precautionary landing on a gravel road. An inspection of the custom made mild steel exhaust revealed that the weld fixing the tail pipe to the muffler had failed in an area which had been wrapped in heat wrap and this is believed to have caused hydrogen embrittlement weakening the area causing it to fail.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: The aircraft was taken for a test flight of one circuit which was fine in the early part of the flight but as the speed built up on downwind, a loud bang was both heard and felt in the lower part of the fuselage. Speed was reduced and the aircraft landed without incident. The fuel tank breather was found to be clear and the seat appeared to be secured but the flap circuit breaker was found to be tripped even though the flaps had not been used during the flight. A close inspection was made of the aircraft and the reason for both the loud bang and the flap circuit breaker tripping. It was found that the lower flap motor mounting point was set into the fuselage of the aircraft skin. This is an area that has no structural members to support the flap motor. It would appear that the airflow over the flaps at cruise speed distort the alignment of the flap jacking screw with the motor housing and this moves the micro switch bar away from the positioning cam. As a result, the flap motor had actuated and run to the end of the thread on the jack screw to cause the motor to stall and trip the circuit breaker. There is a 100 x 100mm section on the lower fuselage where the flap motor is attached that moves up and down with both airflow and flap actuation.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: As the aircraft touched down on the grass RWY it drifted to the left slightly. The tailwheel was not quite on the ground, when the port mainwheel ran over a sprinkler depression and the aircraft suddenly nosed over smashing the propeller and skidding to a stop on the lower front of the engine cowl.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Shortly after takeoff, the Instructor noticed high coolant and oil temperatures coupled with rough running while on downwind. An immediate safe landing was made. Pulled the oil dipstick but was to hot to handle. It was then noticed that traces of coolant were evident on the nose wheel fairing and inside the cowl. Investigation found the coolant hose had come off the intake pipe. RAAus AN270810-1 is applicable. The notice recommends cooling hoses are inspected on a regular basis including at the daily inspection. An article on coolant hoses has also been included in the Licence to Learn February 2020 edition.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot forgot to lower nose leg in landing phase, as a result the aircraft nose contacted RWY. The approach was a straight in, rather than maneuvering for a standard circuit and the pilot admitted he did not complete pre-landing checks as a result. OUTCOME: The pilot has now implemented processes for pre-landing checks regardless of the number of circuit legs flown

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst taxiing to end of RWY 10 for take-off the mainwheels of the aircraft (taildragger) collapsed underneath the fuselage resulting in aircraft pitching forward, the prop striking ground and the aircraft coming to abrupt stop.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: During the aircraft annual check it was noted there were cracks under head of the bolt attaching the elevator balance weight. OUTCOME:The elevator was removed, endcap removed from the elevator and bolt and weight removed. It was then discovered that the end rib is .020 alloy and the balance weight of 1/2 a kilo has flexed and broken the rib. This has occurred both elevators. If the weight had come adrift, it has clearance to be able to roll forward and back. LSA manufacturer has supplied repair scheme.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot had just purchased the aircraft and was undertaking a check flight on the aeroplane prior to a ferry flight to their home state as they had not logged any tailwheel time in over 2 years. The pilot completed two full stop circuits with back track after each landing. On the third approach, with a light cross wind from the right, the aircraft skipped and commenced a swing which was unable to be corrected. The aircraft clipped a RWY light and in the attempt to correct the swing a ground loop resulted. The owner then decided to truck the aircraft back to their home state and accumulate tailwheel currency at or near their home aerodrome. RAAus reminds all pilots to be aware of the importance of Type Training when operating an unfamiliar aircraft.
