OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: Ref to ROTAX 912ULS Cylinder Head MM Assembly Procedures. Collar CAP nuts found to be incorrectly fitted and (x2) seized onto M8 Stud. Cyl#3 (top right stud) and Cyl#4(top right stud) found to be affected. Cyl#3 capped nut freed from M8 stud with smart tap to wrench. Cyl#4 capped nut remains seized to M8 stud. M8 Stud rotates 3mm either way with collar nut and is unable to be loosened. (Top of capped nut had to be cut away to observe the stud and to inject penetrant). It appears that the Thread Sleeve M8 may be rotating inside the block. Observations: Collar CAP nuts have been fitted (in 2017) on top side cylinder head studs. (the capped cylinder head nuts should be inside the rocker cover). Logbook maintenance entry (2017) indicates nuts were tightened to 10Nm + 180 degree turn. Latest rev 912 MM indicates procedure as - 10Nm + 120 degrees. 'Optional' SI-912-025 2016 indicates procedure as - Step 3 - Loosen each M8 collar cap 360 degrees then tighten to 10Nm + 150 degrees. Engine reported to have been, and still is leaking oil.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst conducting and on the last circuit of a lesson based on Circuit emergencies, the Warning caution lights for the Rotax 912IS Lane A and Lane B (ecu redundancy circuits) both started flashing and a warning appeared on the Dyson Skyview system instructing to land immediately. A quick scan revealed the number 1 Exhaust gas temperature was indicating 1200 degrees Celsius, a PAN was declared and an uneventful glide approach conducted without further incident. Fault finding revealed that the number 1 Exhaust gas temperature sensor had failed. Sensor replaced and nil defects identified.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Coming in to land, the aircraft had touched down when the pilot felt a shimmy in the nose wheel. The pilot applied back pressure to lift the nose wheel off the ground for as long as possible. When the nose wheel touched down, the aircraft veered to the left. At this time the aircraft was travelling slow enough that they were able to apply the brakes and bring the aircraft to a complete stop. At this point the pilot didn't know that the nose wheel steering was completely lost and they attempted to turn the aircraft around and taxi off the runway. When the pilot realised this was not possible they turned the aircraft off, made a radio call advising another aircraft that was in the circuit of their intentions to get out of the aircraft and push it off the runway to the nearest taxi way, to which the other pilot acknowledged the call. Once this was completed, the pilot made a radio call advising they were clear of all runways.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: While conducting lesson on circuits, the instructor attempted to demonstrate engine failure after take-off and return to the runway. Power was reduced to idle, adopted airspeed 65/70 knots and lowered the nose to maintain airspeed. The pilot attempted to round out, however as they rounded out struck the ground resulting in a very heavy landing. The Instructor was requested to complete a review with the CFI, however has moved from the location and is no longer instructing. Prior to return to instructing a review process will be required. Members are reminded of the risks involved in attempting to turn back to the runway in an emergency and should elect to land straight ahead.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Radio Failure during arrival (Transmit failure) at YBAF. The pilot requested clearance and read back the clearance, however Tower could only receive the carrier wave, no transmission modulation and requested an acknowledgement of the clearance. The pilot repeated the last transmission again. Again no reception by tower. They then transmitted in the blind "change of intention, full stop at RWY 10R" – the tower could only receive the carrier wave. The tower then requested that the pilot click twice if they were receiving, which the pilot did. The aircraft landed safely on RWY 10R. Further clearances to taxi back were transmitted by the tower and acknowledged by the pilot with 2 clicks as requested.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: On taxi to the runway, the brakes failed approaching the holding point. The pilot reduced the power to help bring the aircraft to a stop before the holding point. This was not possible and the pilot diverted off the taxiway into grass to avoid breaching the active runway.
15/5/2020	OCC2024	Port Macquarie Aerodrome	NSW	The Airplane Factory	Sling 2	Rotax	912ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: The lesson was running late and the aircraft had not been fu...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: The lesson was running late and the aircraft had not been fuelled the previous day. The instructor was organising to refuel the aircraft and had student take aircraft out of the hangar. This break to the instructors’ normal routine combined with the time pressures meant they neglected to remove the tow bar from the nose wheel of the aircraft. They started the aircraft, taxied to runway, completed run-ups and taxied onto runway 21. Throughout these sequences, neither the instructor or the student detected anything wrong and did not hear anything out of the ordinary (the instructor was wearing an active noise cancelling headset). The student began the take-off roll and a noise was detected as speed increased that sounded like wheel bearings scraping. Just after lift-off the instructor took over and landed the aircraft and taxied back off the runway. The instructor exited the aircraft and found the towbar still attached but trailing behind the nose wheel.
12/5/2020	OCC2017	Cessnock Aerodrome	NSW	Jabiru	J230-C	Jabiru	3300A	OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot flew from Mudgee to Singleton at 7500ft then cruise...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot flew from Mudgee to Singleton at 7500ft then cruise decent to Cessnock 1200ft. Shortly after joining the circuit, downwind runway 35, the aircraft was abeam the threshold the engine ran rough and began to lose power. The aircraft was following another who was 1/2 a mile ahead so the pilot called turning base 35 for a full stop and flew an abbreviated circuit. All went well and the pilot exited the runway with communication. Review identified likely cause due to carburettor icing.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Training was being conducted using both runway 05 and runway 36 at Ballarat Airport. These two runways intersect mid field. There were multiple aircraft in the circuit making the visual positioning of aircraft and situational awareness quite complex and difficult. The pilot of the Zenith entered 36 believing another aircraft was on cross wind 36 giving them ample time to take off and join 36 circuit for training. The pilot of the Zenith rolled and took off, then heard a final 05 call from the other aircraft they thought was on cross wind 36. The pilot had not at that time heard a base call for 05 to alert them that this aircraft was circuiting on 05. The Zenith continued to climb out at best angle of climb and was over 400+ AGL by the time they crossed the intersection of 05 and 36. The pilot of the aircraft landing on 05 called go round and passed behind and below the Zenith. The pilot of the Zenith was of the opinion that the other aircraft could have safely landed below them and they would have had at least 400ft clearance.
5/5/2020	OCC2012	Romsey Aerodrome	VIC	Ekolot	KR-030 Topaz	Rotax	912 UL	OCCURRENCE DETAILS SUBMITTED TO RAAUS: A pilot was on final approach on RWY 03 at Romsey Airport whe...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: A pilot was on final approach on RWY 03 at Romsey Airport when they heard an aircraft make a radio call announcing “aircraft near Romsey Airport I have you insight and will remain clear”. The pilot looked around and found the other approx. 3 aircraft wingspan distance to their right at same altitude it then made a steep bank to the east. The pilot conducted a go-around and joined cross wind for alternate RWY 33 and landed uneventfully. Pilots are reminded of their requirement to remain clear of the circuit area when transiting within the vicinity of an aerodrome as well as maintaining regular radio calls and an active lookout at all times.

OCCURRENCE DETAILS SUBMITTED TO RAAUS: Whilst conducting a dual NAVEX with a touch and go at YCWR RWY 33, on the climb at 300ft AGL the engine started vibrating and losing power. The Instructor took control of the aircraft and conduct a low level return to RWY 33. They made a PAN PAN call and change intentions to touch down on RWY 12. The Instructor made an uneventful landing with no damage to the aircraft. Review identified failure was likely due to a carburettor issue and was resolved with an L2 maintainer.
3/5/2020	OCC2015	The Oaks airfield	NSW	Aeroprakt	A22L Foxbat	Rotax	912 ULS	OCCURRENCE DETAILS SUBMITTED TO RAAUS: During a routine daily inspection by a senior flight school i...
OCCURRENCE DETAILS SUBMITTED TO RAAUS: During a routine daily inspection by a senior flight school instructor, a crack was identified at the base of a ground adjustable composite propeller blade near where it enters the mounting hub. The aircraft was immediately grounded and the L2 maintainer notified. Shortly thereafter the crack was inspected by the L2 maintainer and it was decided to remove the propeller for further inspection. Prior to removal, the propeller was inspected and checked for possible damage caused by a strike or a faulty installation procedure. There was no evidence of any type of strike and all the mounting bolts were tensioned to the require torque setting prescribed by the propeller manufacture. A check of the pitch setting of the 3 blades identified the damaged blade was approx. 1.5 deg’s in lead of the other 2 blades. The propeller was fully disassembled for further inspection. Where the blades mount into the split hub there were signs of light corrosion on all 3 blades between the aluminium split hub and aluminium crush tube, with no other apparent signs of any damage. With the propeller fully disassembled the crack on the damaged blade became more evident, the crack is confined to the what appears to be an aluminium crush tube which is mounded into the composite blade. The crack commences from just where the blade exists the split hub at the split line for both hub sections and extends for approximately 10mm outwards and finishes at the outer edge of the aluminium crush tube.
