OCCURRENCE DETAILS SUBMITTED TO RAAUS: DEFECT: The Bowden cable used to operate the carburettor heat on this aircraft has been configured so that when the control knob in the cockpit is pilled, the cable end at the carburettor extends. The change f direction in the cable's action is achieved by the single wire carburettor heater control cable having a 180 degree bend half way along its length. In the form of a tight 'U', and doubling back along itself for a couple of inches. The cable sleeve is in two separate parts so that the portion of the cable with the 'U' bend is exposed, and free to move outside the sleeve. On this particular aircraft the cable sleeves were not supported at the ends near the 'U' bend. This allowed the cable sleeves to move with the control cable and prevent the carburettor heater valve from operating correctly.
DETERMINED OUTCOME: This issue has been rectified and the Maintenance Manager has also notified the manufacturer of the issue. |

|
Warp Drive Propellor hub failed in flight after 5-10 seconds of vibration. The pilot attempted to find a motor setting with minimal vibration however the ensuing failure occurred very quickly. The engine was then shut down and a forced landing site ensured. A "MAYDAY" was called and EPIRB activated. The landing was conducted as slow as possible with motor off, the flaps fully down, and switches off. The canopy was open (it opened after the hub failure due to the vibration) and the pilot ensured the passenger was tightly secured. The aircraft was damaged on landing however no injuries were reported.
OUTCOME: Factory have issued a service bulletin for an inspection schedule on the Warp Drive Propeller Hub at each 100 hourly. The factory will also supply a letter of authorisation for the fitment of Australian made Bolly 3 blade ground adjustable propellers. Members are reminded to contact the appropriate Search and Rescue authorities to clarify a safe landing when calling a "MAYDAY" and activation of a EPIRB. |

|
During take-off the pilot opened the throttle to get up to speed however the aircraft did not seem to be performing, despite the gauges reading okay. The pilot decided to abort the take-off however was too late to pull up before the end of the RWY. The aircraft went through a ditch and several bushes, coming to a stop approximately 45m from the end of the RWY. After inspection it appeared that the handbrake of the aircraft may have been engaged.
OUTCOME: Investigations revealed the hand brake of the aircraft may still have been engaged reducing the performance of the aircraft. Pilots are reminded of the importance of using checklists to ensure the aircraft is configured correctly for the intended phase of flight, and early actions to reject take-off if reduced aircraft response is recognised. |

|
On approach to a one way private airfield, an unexpected tailwind was encountered. The pilot was additionally forced to hold off the touch-down due to noticing unexpected loose stones on the approach end of the paddock. The plane was landed normally on the remainder of the paddock however the grassed surface had a pronounced undulation which greatly reduced the braking effectiveness. The plane was almost brought to a stop however made contact with some bushes at the far end, resulting in one propeller blade being broken.
OUTCOME: On approach to a one way private airfield, an unexpected tailwind was encountered, and in an effort to avoid loose stones an extended float occurred. The aircraft landed normally on the remainder of the paddock, but the grassed surface had a pronounced undulation which greatly reduced the braking effectiveness. The aircraft was almost stopped when it made contact with bushes at the far end, resulting in one propeller blade being broken. Appropriate engine teardown and required maintenance was subsequently conducted. |

Whilst conducting a touch and go on the grass RWY04R, during the climb out a magpie took flight and impacted the inboard leading edge of the port wing.
OUTCOME: No damage sustained to the aircraft. Archerfield had two reports in early 2016 of bird strikes and information is contained in the ESIR for the local area which outlines the seasons when the bird population increases. RAAus will continue to monitor for any future recurrence of this type of incident in this area. |

|
During an instructional flight a radio call joining downwind RWY15 at YDUN was made. Approximately 30 seconds later another aircraft was heard giving a 3 NM call inbound for joining right downwind RWY33. This put both aircraft on a collision course. The instructor had the student give a turning base RWY15 Dunwich call, no response was heard from the other aircraft. On short final the instructor heard the other aircraft call they were joining downwind on RWY33. As it was likely that the Tecnam would have to go round the instructor made the radio call that they may have to go around and suggested the second aircraft leave the circuit area to which they replied OK. The Tecnam landed and the other aircraft returned to the circuit and landed on RWY15.
OUTCOME: RAAus Operations Manager has reviewed this report. De-identified information regarding this report has been forwarded to CASA to follow up with the VH registered aircraft involved. |

|
The landing was on a one-way private strip. The approach was conducted too high and too fast to land safely but the pilot left the option of going around too late (tall heavy timber was in the way) and committed to landing. The aircraft was steered towards fallen tree branches in order to dissipate forward speed however the right wing struck a tree trunk about 600mm from the tip. The aircraft spun around 180° and the rudder impacted with another tree.
OUTCOME: The pilot persisted with an unsuccessful approach beyond a point where a missed approach was possible resulting in impacting vegetation during the ground rollout resulting in substantial aircraft damage. Comment from Operations: Pilot's should always have a pre-determined decision point in the final approach and apply conservative margins for early missed approach procedures, particularly where short field or one way operations are being conducted. |

|
On the third circuit the pilot had to take evasive action due to an animal on the RWY. This resulted in the aircraft ground looping in long grass damaging the propeller.
OUTCOME: This is the first report of this instance regarding an animal or bird strike in this area. Long grass makes it difficult for pilots to visually identify animals near the runway and as such it is suggested that aerodrome users inform their local aerodrome manager when long grass has not been mowed to ensure their is little likelihood of an animal strike recurring. |

|
Student was conducting second attempt at takeoff. A short discussion was held to go over the routine again and the student commenced takeoff with the instructor directing. When the tail wheel came up, the aircraft pointed into wind (slight left divergence), and the instructor applied a small pressure on the right rudder to ensure the nose didn't continue further left. As the aircraft lifted off it tipped slightly right and the instructor tapped the stick to the left and said words to the effect of keep the left wing down. The aircraft suddenly pitched up and over to the right turning through approximately 270 degrees while clear of the ground and struck the ground near vertical nose down. It then bounced back and onto the wheels going backwards. During this period the instructor attempted to take over however, due to the very rapidly developing (nose down at this point) situation, cut the power and accepted that there was no choice but to fly it in. Upon impact the instructor checked which side would make for the best exit - the left aide of the aircraft was ablaze so the instructor opened the right side doors and commanded evacuation to the right. The student and instructor made a speedy exit. The aircraft burned due to the engine being torn free along with the fuel lines.
OUTCOME: Operations Manager and CFI reviewed incident and the possible wake turbulence from a passing Dash 8 or thermal activity resulted in loss of control on the take off roll. |

CFI was conducting post maintenance check flight. Fuel load for the flight was 25L. Fuel had not been added since the previous flight. Pre-take off engine run-ups were conducted. After take off, the engine power rapidly reduced below that required to maintain straight and level flight. A turn back to the departure RWY was not safely practicable so the pilot elected to land in a paddock. The engine continued to run smoothly at low power until the aircraft was on the ground. The power loss occurred after, but not co-incident with, a cruise-climb power setting being selected. The aircraft landed successfully.
OUTCOME: A full inspection was conducted and no clear cause for the rough running of the engine was identified. The incident flight was a post-maintenance test however inspection showed no clear causal factor. Carb icing was also considered a possibility due to the conditions at the time of the incident being in the second highest band IE on the icing probability chart (moderate icing at cruise power) however there was no roughness or kicking in the engine to signal to the pilot the need for heat (there was simply a rapid power-down). The aircraft has been fully inspected and back in normal service. |

At 4000ft AGL the pilot started gliding operations as planned for the test flight. The glide tests were done at set speeds. Halfway into the flight the engine stopped and the pilot could not restart the engine. The pilot performed a standard forced landing. The aircraft restarted on ground with no other issues found.
OUTCOME: The pilot reported that it was good conditions for icing and suggested that they clear the engine more frequently to prevent this from happening. RAAus Technical Manager reviewed this report and is aware that the pilot is currently exploring the amateur built process, including conducting the appropriate flight testing in accordance with the flight test procedure. |
