OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst conducting a dual flight training exercise, after being airborne for approx. 35-40 minutes conducting air exercise without incident (all engine temps and pressures good). On recovery from a demo of stalling in a descending turn, the aircraft, on full power (3000 RPM) at about 5400ft, began to miss and run rough, throttle closed but engine seized within 5 seconds. A Mayday was issued to Melbourne Centre (120.75) and acknowledged. The Instructor selected suitable landing area (sheep paddock) and carried out a forced landing without further incident, damage or injury. They then called 000 to report their position and waited for emergency services. The aircraft was recovered and taken to Jindabyne Airfield where an L2 Maintainer inspected engine and reported major failure of piston in No.1 cylinder. The engine is to be removed and returned to the manufacturer for further diagnosis.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The student was conducting their first solo after completing five circuits to a safe standard. Additional traffic had just landed, slowing down to exit the runway. The student lined up and started rolling without realising the traffic still had not exited the runway via the taxiway. The traffic subsequently exited via taxiway safely but the student was startled during the initial take-off roll, reduced the power and came off the side of the runway with no damage. The student will undertake further assessment flights with an Instructor prior to solo.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Flying from Flinders Island to Tasmania, via Cape Barren Island when the engine failed over water approximately five nautical miles South of Cape Barren Island. The airstrip on Cape Barren Island is on the Western side and the aircraft was positioned to the South. The pilot glided toward the airstrip, not expecting to get there, however, a dirt road ran from the south side of the island toward the airport. The pilot elected to land on the dirt road. The road was not wide enough for the wingspan and the right-hand wing impacted with the foliage spinning the aircraft 180 degrees. No injuries were incurred. On inspection of the engine, it was found that the exhaust valve on the number three cylinder had failed.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: When the aircraft was on late final at 50ft a Cockatoo struck the port wing. RAAus continues to monitor bird strike and wildlife reports at aerodromes to ensure correct ERSA/NOTAM information is in place and to enable reporting to the aerodrome proprietor.

14/12/2019	OCC1901	Launceston Aerodrome	TAS	Jabiru	J160C	Jabiru	2200B	OCCURRENCE DETAILS SUBMITTED TO RAAUS: At the termination of a training flight the pilot was asked t...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: At the termination of a training flight the pilot was asked to contact the tower.The instructor was advised by the tower personnel that a take-off was made without a clearance. On review the instructor didn't recall all instructions from the tower, but recalls the direction to make to make a left turn. The instructor further reviewed the incident with the student and acknowledged that cockpit patter may have interfered with interpreting the clearance correctly. Sterile cockpit disciplines have been improved to avoid future occurrences of this type. RAAus reminds instructors to consider the increased demands on situational awareness and procedural disciplines when operating in controlled environments and to ensure that these elements are prioritised when under Surface Movement Control (SMC) and an airways clearance. Where any doubt may exist, Instructors are reminded to request a repeat transmission from ATC rather than assume a clearance has been given.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot had been conducting circuits and EFIC, on the last circuit a slight vibration was noticed. Late downwind power was reduced and turned early base for RWY 32, power reduced to idle. The landing was carried out without incident. On investigation the CHT and EGT on No2 cylinder indicated no power being produced from this cylinder. Spark Plugs were removed and found fouled with Oil. Removed the head which appeared to have no fault. Inspected the cylinder and the piston appeared to have a seized ring, removed barrell, some marks were noted on the piston skirt and closer inspection of the barrel revealed a crack at the 4 o'clock position at the bottom of the piston travel.

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.
