|
During circuit training on RWY 17L at YMMB, after making the final touchdown it was realised there was an aircraft on finals behind them so made the decision of exiting on RWY22. The pilot missed the turn on to taxiway Foxtrot and continued on RWY22. As soon as the pilot realised the error the pilot stopped and contacted YMMB ground. It was concluded that the aircraft had just crossed the holding point for RWY17R, which was also the duty RWY the time. The pilot had the gable markers ahead, indicating the entry into a RWY.
OUTCOME: A joint visit was undertaken between Airservices ATC staff, the school's training manager and RAAus Operations to identify specific operational issues and an appropriate working process to address these. Agreed attendance at monthly safety meetings by the Flight school and Airservices and the removal of a taxiway where regular occurrences have occurred has been applied as appropriate mitigation with continued monitoring being adopted. |

|
During a training circuit it was noted the engine was running rough on approach. At first it was suspected icing and the pilot took appropriate actions with no improvement. By the time the aircraft was on short final, below 200ft approximately the rough running drastically escalated resulting in the engine failing completely. The aircraft landed safely and some basic checks carried out on the RWY resulting in restarting the engine.
OUTCOME: Upon Inspection of the aircraft (by the engineer responsible for the usual maintenance) it was confirmed to have been a failure in the mechanical fuel pump. Although the electrical auxiliary pump was running at the time this particular failure still resulted in loss of power. This is a type certified engine in the pioneer. |

|
OCCURRENCE DETAILS SUBMITTED TO RAAUS: The aircraft landed with a flat main wheel tyre, damaging the disc rotor. Due to the design of the brakes, the brake disc diameter is larger than the rolling flat tyre diameter of the wheel. This can allow the disc rotor to freely roll on the runway surface causing bending and burring damage to the thin disc, rendering it u/s or worst case, jamming in the caliper assembly, locking the wheel from turning.
DETERMINED OUTCOME: This occurrence has been referred to CASA engineering and airworthiness branch and the manufacturer for further monitoring and action where required. |

|
After an uneventful take off the pilot proceeded to make track and climb on a heading of 000 towards Charleville. At an altitude of about 2700ft the pilot started to smell a faint smell of oil and was proceeding to re-scan the gauges, when sparks erupted from under the cowl and the engine lost power. The pilot cycled the magnetos and established there was no power. The pilot then switch off magnetos, made two May-Day calls on the area frequency and the multi-com frequency and commenced a gentle turn away from a wooded area towards more open country to the south nearer to a Farmstead. The pilot selected a landing site that was clear of large trees and that had less shrub and proceeded to land, but as the aircraft was slowing the right wing collided with a small dead tree. The aircraft then ground looped in a clockwise direction and came to stop. The pilot then self extracted without harm and proceeded on foot the homestead to raise the alarm.
DETERMINED OUTCOME: The aircraft is a 19 amateur built but had a type certified 912 A rotax. Aircraft has a total time of approx 470 hours in 24 years. The problem was identified as a value issue but until the engine is pulled down nothing further at this stage. The aircraft and engine was L2-LAME maintained. The owner stated that the engine appeared to run a little rough prior to take off. In time a pull down report may be supplied. |

|
Whilst the aircraft was taxiing the nose wheel became stuck in loose dirt. Over use of right rudder by the pilot caused rudder cable to break.
OUTCOME: This is an amateur built aircraft where the design standards are not mandated. On review of similar types of aircraft it has been identified that a bike brake cable is sometimes used in this application and is usually supplied with the kit. The RAAus Technical Manager has spoken with the aircraft designer of this amateur build regarding parts. |

|
The aircraft was tied down alongside the hangar when a very strong gust of wind broke the tie down ropes and flipped the plane upside down, resulting in the wing landing on a club members’ car.
OUTCOME: A freak convection gust (which was later reported to exceed 70kph caused the aircraft to lift from its tie downs which were tied down to water ballast containers). Consequently one rope failed when the aircraft was lifted and one rope attached to a water container snapped allowing the aircraft to flip over an adjacent fence and onto the car. No weather conditions were forecast to indicate extreme convection, storm or frontal activity according to owner. |

|
As the pilot was turning right onto downwind, a glider was coming towards the aircraft from the slight right hand side (up the downwind). The pilot took action to avoid the glider as did they, the pilot radioed the glider to say they had been seen and avoided, however got no response.
OUTCOME: The incident has been reported to the Gliding Club safety committee and CFI for follow up. It is likely it was a glider and pilot not familiar with the airfield and right hand circuits on RWY 23, the actions from the gliding club address any identified issues. RAAus Operations Manager has reviewed the report, no further action at this time. |

|
On flight from Wollongong to Wedderburn oil pressure dropped to 0.8 Bar which is well below the minimum of 2 Bar for the Rotax 912 ULS type. The pilot made a call to alert other traffic to the inflight emergency and priority given. An uneventful landing was made.
An examination showed the lid on the oil tank had tilted up on one side allowing oil to escape. Residual oil in tank was found to be 600mm. Oil was replaced, the system purged of air and the oil pressure on start-up returned to normal. Compression afterwards was as expected and no damage to engine evident. During the emergency the CHT remained stable at 100 degrees C which is normal and the oil temperate was not elevated.
DETERMINED OUTCOME: It is likely that this issue occurred due to a faulty O-ring on the oil tank. Owner operator reminded to review LSA manufactures maintenance schedule. |

|
When taxiing out to RWY35 via 23, at the gable markers the pilot positioned the aircraft to look for any traffic on final of 35. Nothing was sighted. Another aircraft was approximately 300m downwind abeam the piano keys and gave a call to state they were doing a glide approach onto 35. The taxiing aircraft made a call to say it was entering and lined up for an immediate intersection departure. As they entered the RWY the pilot noticed the second aircraft was approx. still 700AGL at a 45 degree to RWY35 about 1800m away 1/2 way on base.
Determined Outcome: All schools contacted to ask them to co-ordinate operations using effective alerted see and avoid and appropriate airmanship for RAAus flight training schools |

|
Due to a miscalculation of fuel usage, the aircraft suffered fuel starvation on late finals during circuit practice. The engine continued to run but not make power. After exiting the aerodrome boundary of the active RWY the aircraft was inspected and found that there was no usable fuel remaining. After fuel was added the aircraft started and engine operated normally.
The pilot has since re-read the Drifter flight manual and recalculated fuel burn for further operations.
OUTCOME: There is currently no minimum fuel requirements prescribed for day VFR fuel reserves. Pilots are reminded to reference the pilot operating handbook and confirm fuel burn rate as there are a range of factors that affect this. See CAAP 234-1(1) Guidelines for Aircraft Fuel Requirements. |

|
When on late downwind after ensuring that there was sufficient spacing between the preceding aircraft (on mid to late final) the pilot closed the throttle and made a radio call that they were executing a practice glide approach. When at approx. 200-300ft above ground height on short final, a radio call was heard indicating that an aircraft was entering the active runway for an intersection departure and an aircraft was seen to enter, without time for a responding radio call. The pilot of the first aircraft immediately initiated a go around, however there were then three aircraft in relatively close proximity on upwind.
Outcome: This incident highlights the importance of aerodrome users working together to ensure safety. RAAus strongly recommends that recreational flying clubs at all airports seek to form or become a part of an already established aerodrome users safety committee. This type of committee should allow all users to express their concerns and needs in a forum where issues can be dealt with in a professional and respectful manner. |
