Circumstances:
The pilot attended the Bankstown Briefing Office at about 0600 hours. He was briefed concerning the current weather conditions at Bankstown Airport, which were Instrument Meteorological Conditions (IMC) but were Improving to VMC; and the relevant meteorological forecasts which indicated, for his proposed route, that he might experience some difficulty in maintaining flight In Visual Meteorological Conditions (VMC). The pilot's licence was not endorsed to permit him to operate in other than VMC. He then submitted a flight plan for a flight from Bankstown Airport to Warracknabeal and return, proceeding over Marulan the estimated time interval thereto being 33 minutes, the flight to be conducted in accordance with the Visual Flight Rules (VFR) at altitudes not exceeding 5000 feet. The aircraft departed Bankstown Airport, in VMC, and established two way communication with Sydney Flight Service Unit (FSU). At 0748 hours the pilot advised the Sydney FSU that he was "returning to Camden, estimating Camden at one five". In response to a query the pilot advised "weather okay". No further communications were received from the aircraft. At about 0755 hours the aircraft was heard and observed flying in an easterly direction some 20 kilometres north-northeast of Marulan. There was low cloud and some light rain in the area. The aircraft was flying below the cloud base and was at a height of 500 feet to 200 feet above undulating terrain, proceeding towards rugged terrain which was gradually rising. Subsequently the aircraft proceeded over a ridge line out of the sight of witnesses. Shortly thereafter the engine noise ceased abruptly. The police were alerted and search and rescue action was initiated. The wreckage of the aircraft was located some eight hours later. The aircraft had crashed on a heavily timbered 12 degree upslope about 100 feet below a ridge line. At Impact the aircraft was in a nose down attitude and was banked some 45 degrees to the right. The right hand propeller was feathered and the engine had not been operating at impact. The left hand engine had been under power. The landing gear and flaps had been fully retracted. The available evidence Indicates that the gross weight of the aircraft was at or about the maximum permissible all up weight. Examination of the right hand engine revealed massive internal failure which had commenced with the failure of the right hand dowel In the Number 2 main crankcase bearing. It is probable that the dowel failed because of abnormal loads resulting from loss of bearing nip associated with crankcase fretting at the lower through bolt of the Number 2 bearing saddle. It is estimated that the engine had operated some 170 hours since issue of the last maintenance release on 26 October 1976.
Probable cause:
The probable cause of the accident was that, in the conditions pertaining, the single engine performance of the aircraft was insufficient to ensure maintenance of adequate terrain clearance whilst flying over undulating terrain at a low eight. Internal structural failure of right hand engine, Lycomtng GSO480-BIC6 Serial number L3050-33. Left hand engine carburettor air temperature control valve detached from actuating shaft.

Circumstances:
At approximately 1103 hours Eastern Standard Time (EST) on 6 August 1976 the pilot of Nomad N24 aircraft Serial Number 10 encountered control difficulty at a height of about 950 feet immediately after taking off at Avalon Aerodrome. The aircraft entered a descending turn to the left through about 175 degrees and struck the ground. The pilot was killed; the occupant of the other pilot seat, an observer, sustained injuries which resulted in his death two days later; and the third occupant, the flight test engineer, was seriously injured.
Probable cause:
The cause of the accident was that the simplified design criterion which was used to justify freedom from flutter during the flight testing of various tail plane modifications was not valid for a design which included tab trailing edge T strips.

Circumstances:
The aircraft departed Polo Flat at 0750 hours on a planned flight to Khancoban, Talbingo and return. There was dense fog at Polo Flat at this time and the aircraft took off and climbed through fog until it was in clear conditions above. At Cooma Aerodrome, fog which had existed earlier dissipated about 0715 hours and the weather at that location then remained clear. When the aircraft returned to the Polo Flat area shortly after 0930 hours, fog was still present but it was commencing to break with patches of blue sky visible from time to time. Information regarding the weather conditions was communicated to the, pilot who had established radio contact with the base operations officer at Polo Flat. Shortly after the aircraft arrived in the area it was observed to make what appeared to be a landing approach into the north but when it had descended to a height of 10 to 15 feet the approach was discontinued and it climbed away. After flying for some time above the fog at a height of about 500 feet the aircraft was heard approaching from the south and the operations officer heard the pilot transmit the words 'hit the...'. Shortly afterwards the sound of an impact was heard. The port wing of the aircraft had struck the radio transmitter mast 32 feet from the top and the aircraft crashed to the ground in a steep nose-down attitude some 146 metres north of the mast. A fierce fire developed shortly after impact.

Probable cause:
The probable cause of the accident was that the aircraft was operated at an unsafe height in weather conditions in which the pilot was not able to maintain the visual reference necessary to ensure adequate clearance from obstructions.

Circumstances:
DH-114 Heron registered VH-CLS was operating Connair Flight 1263 from Alice Springs to Cairns landing at Mount Isa en route. At 12:57 hours VH-CLS taxied to runway 30 at Alice Springs and was cleared for takeoff. The flight landed at Mount Isa at 15:35 hours after making a visual approach. At 16:46 hours VH-CLS taxied to runway 34 at Mount Isa, and the flight reported its departure as 16:55 hours at which time it was climbing to its planned cruising altitude of 7000 feet. As the flight progressed position reports at the appropriate reporting points were received. At 18:01 hours, VH-CLS advised that it was descending to cruise at 6000 feet. Subsequently, at 18:49 hours, VH-CLS reported as being at the Saucebottle Creek position, 146 km southwest of Cairns, at an altitude of 6000 feet. The crew indicated an ETA at the Biboohra VOR, 35 km west of Cairns, of 19:12. VH-CLS was then advised by the Cairns aerodrome/approach controller, through the Cairns Flight Service Unit (FSU), to expect an ILS approach to runway 15 at Cairns Airport. At 18:54 hours the Cairns aerodrome/approach controller issued an air traffic clearance, for transmission through the Cairns FSU, authorising VH-CLS to enter the control area via the 049 degree radial of the Biboohra VOR cruising at 6000 feet and using an altimeter setting of 1006 millibars. At about 18:55 hours, the Weather Service Office (WSO) located at Cairns Airport observed a thunderstorm, without precipitation, in the vicinity of the airport and the following 'special' aerodrome weather report was issued: Wind : 360 degrees at 6 knots, visibility : 10 km or more, thunderstorm without precipitation, 1/8 cumulonimbus clouds, base 3000 feet, 4/8 cumulus, base 2300 feet, 4/8 strato cumulus, base 4000 feet. This was reported to the crew. At 19:10 hours, VH-CLS reported to the Cairns aerodrome/approach controller that it was over the Biboohra VOR at 6000 feet and, following confirmation by VH-CLS that its 'preferred approach' was an ILS approach, it was cleared 'on the Biboohra zero four nine radial, descend to three seven zero zero for an ILS approach runway one five, and report at Buchan Locator'. VH-CLS acknowledged this instruction and advised that the aircraft was leaving 6000 feet. At 19:17:29 hours, VH-CLS reported over the Buchan Locator turning outbound onto a heading of 330 degrees this being the standard ILS procedure; the aerodrome/approach controller cleared the aircraft for an ILS approach and instructed it to report leaving 3700 feet. At 19:20:54 hours, VH-CLS reported 'leaving three seven zero zero' implying that the aircraft had commenced the final approach segment of the ILS approach. The aerodrome/approach controller acknowledged the report and radioed: 'wind from the northwest, maximum downwind component runway one five not above six knots, runway wet, clear to land'. At 19:22:53 hours, the controller notified VH-CLS 'there's a moderately heavy shower at the field now, visibility er is reducing as the shower moves south, visibility to the south at the moment er in excess of four thousand metres, high intensity approach and runway lighting is on, advise when you would like the intensity decreased'. VH-CLS acknowledged. At 19:26:23 hours, VH-CLS reported 'going round' and the aerodrome/approach controller instructed VH-CLS to 'make missed approach on a heading of zero three five and climb to three seven zero zero'. VH-CLS turned away from the airport, descended to a low height above terrain, and completed about 270 degrees of a left hand orbit. It then entered a turn to the right during which it descended and crashed.
Probable cause:
The cause of the accident was that, following misalignment of the aircraft with the runway and abandonment of the landing approach, the pilot in command did not immediately initiate a climb to a safe altitude. Why such action was not taken has not been determined.

Circumstances:
The flight departed from Essendon Airport at 0050LT. At 0122 hours the flight reported to the Melbourne Flight Service Unit (FSU) that it was then at the Westgate reporting point cruising at 3,500 feet, and its estimated time of arrival at the West Bass reporting point was 0159 hours. At 0145:44 hours VH-SJQ advised the Melbourne FSU 'we have an engine failure on the port side, we have it feathered and are returning to Melbourne'. In response to a request from the FSU the flight advised it was able to maintain height 'at the moment'. At 0148:54 VH-SJQ confirmed that 'the port engine has failed and is feathered' and shortly thereafter advised an estimated time of arrival at the Primegate reporting point en route to Essendon Airport. The Uncertainty Phase of the search and rescue procedures was declared by the Melbourne Air Traffic Control Unit (ATC). At 0151:58 hours the flight advised the Melbourne FSU 'we are making a slow descent to one five zero zero' and, in answer to a query, reported 'we're unable to maintain our height with our rated power'. The Alert Phase of the search and rescue procedures was declared by Melbourne ATC, and a Bristol 170 Mark 31 aircraft en route from Launceston to Essendon Airport was diverted to intercept VH-SJQ and act as an escort. At 0157:46 hours VH-SJQ reported 'four eight DME Wonthaggi', and shortly thereafter, reported 'tracking one eight three on the Wonthaggi VOR'. At 0203:00 hours VH-SJQ transmitted a distress call and reported 'we're passed fifteen hundred feet and still going down'. The position of the aircraft at 0203:57 hours was reported as 'on the one eight six radial Wonthaggi and we are three seven DME'. The Distress phase of the search and rescue procedures was declared by Melbourne ATC and a second northbound aircraft was diverted to intercept VH-SJQ. At 0204:32 hours VH-SJQ reported 'we're down to nine hundred feet at the moment'; at 0207:42 hours, 'at six hundred feet at the moment; at 0212:55 hours, 'two two DME'; at 0213:22 hours, altitude was 200 feet; 0214:31 hours, 'we're down to one hundred feet'; and, at 0215:23 hours, 'this is a final MAYDAY call, we are approximately one eight DME and our altimeters registering zero feet'. Melbourne FSU then transmitted a ditching report of moderate seas with a moderate south-westerly swell; this was acknowledged by VH-SJQ. The escort aircraft then heard further transmissions from VH-SJQ which indicated that both altimeters were reading zero; the crew could see the tops of waves; and DME distances of 16, 15 and 14 were transmitted, the latter being the last transmission heard from the aircraft the time being about 0218 hours. Neither of the escort aircraft sighted VH-SJQ. Post analysis of the meteorological information indicates that the weather in the area of the accident was: surface wind from 280 degrees (True) at 15 knots, scattered cumulus cloud base 2,500 feet, scattered stratus cloud base 1,200 feet, patches of sea fog, visibility 40 kilometres reducing to 4,000 metres in rain showers, temperature 12° Celsius. It is probable that the temperatures at 1,500 feet, 2,500 feet, and 3,500 feet were 9.5°, 7° and 5° Celsius respectively. The conditions were not conducive to the formation of airframe or carburettor icing, and search aircraft in the area did not encounter any such icing.
Probable cause:
Due to lack of evidences, it was not possible to determine the exact cause of the accident. Analysis of the information available indicates that the flight profile flown by VH-SJQ is compatible with the aircraft having been flown at an indicated airspeed of 95 knots, and a power output from the starboard engine of 1250 BHP, i.e. 26 per cent less than the normal maximum power available in the conditions which prevailed. The pilot did not indicate in detail the nature of the difficulties he was experiencing, and as the majority of the aircraft wreckage has not been found it has not been possible to determine why he shut down the port engine; whether or not there was a degradation in the power output of the starboard engine; or whether there was some other factor which might have affected the performance of the aircraft. It might be significant, however, that at 0208:33 hours when a crew inter-communication was inadvertently transmitted from VH-SJQ, it was stated 'cylinder head is about three forty, oil pressure is around about eighty, oil temperature is about ah sixty five'. Such an oil pressure and temperature is normal, but the reported cylinder head temperature is 30 degrees Celsius in excess of the permissible emergency maximum.

Circumstances:
Tracker N12-153608 was catapulted from the carrier at 2200 hours on 9 February 1975 to carry out an anti-submarine warfare close support task. The night was unusually dark with no visible horizon so that approximately three hours of the flight were spent in Instrument Meteorological Conditions (IMC). At 0323 hours the following morning, the aircraft attempted a routine landing using the mirror landing system as an approach aid. In the days preceding the accident, the mirror setting had been changed from an approach slope of 4° to 4.5° but the pilot had not been informed of this. In consequence, the approach was slightly high and fast, the aircraft failed to pick up an arrester wire, an event known as a "bolter", and it subsequently crashed into the sea approximately ten seconds later. All four crew members managed to escape from the sinking aircraft and were rescued uninjured. Accident occurred off the Jervis Bay, in the Tasman Sea.
Source: Phil Thompson
Probable cause:
Applied Report 78 concluded that the most probable cause of the accident was that the pilot was affected by unrecognized disorientation associated with somatogravic illusion and flew the aircraft into the sea. Factors thought to have contributed were:
a. the exceptionally dark night,
b. the pilot's unawareness of the change of settings to the mirror landing aid,
c. the pilot's lack of any previous bolter experience,
d. the need to monitor engine instruments instead of the VGI as the aircraft was rotated.

Circumstances:
Fokker F-27, registered VH-EWL, was operating as East-West Airlines Flight 752/753 from Sydney (SYD) to Orange, Bathurst and back to Sydney. The flight departed from Sydney at 17:06 hours and proceeded to Orange without incident. The flight then departed from Orange at 18:10 hours and, flown by the First Officer, the aircraft cruised at an altitude of 5250 feet which is the lowest safe altitude for the route. There was no cloud below the aircraft and the visibility was unrestricted. At Bathurst the weather was reported as a five knot wind from the north-east and the altimeter setting was 1021 millibars. The crew commenced the descent from a position about 5.5 km west of the aerodrome, in visual conditions, with the lights of the city of Bathurst and the runway lights clearly visible. Initially, it was intended to overfly the aerodrome and then make a left-hand circuit preparatory to landing on runway 17, but when the captain saw what appeared to be a light rain shower slightly east of the runway 35 threshold, and which might have involved penetration during a left-hand circuit to runway 17, he decided to land on runway 35 instead. At 1817:30 hours the captain called Sydney Flight Service reporting that the aircraft had arrived in the Bathurst circuit area. The aircraft, which was still being flown by the First Officer, was turned some 90 degrees to the right and it joined the left downwind leg of the traffic circuit for a landing on runway 35. The aircraft proceeded downwind a little further than is usual then turned onto base leg of the circuit by which time all cockpit checks had been completed except for setting the engine fuel trims to 'full increase'. The captain states that whilst the aircraft was on the base leg he checked that the water methanol lights were on, and that the fuel trim indicators were at 'full increase'. The aircraft was turned onto final approach for landing, at which time the landing gear was down, 26.5 degrees of wing flap had been extended, it was aligned with the runway centre-line and no drift was evident. Flight conditions were smooth. Light rain was then encountered and the windscreen wipers were switched on to operate at slow speed. The flight path appeared to be normal at an airspeed of 110 knots reducing to 100 knots with the rate of descent stabilised at some 700 ft/min. At about this time the aircraft passed over the Great Western Highway (730 metres south of the runway 35 threshold) and at the normal height of about 300 feet above terrain; two or three noticeable turbulence bumps were then encountered and the aircraft commenced to drift to the left of the runway alignment. The aircraft heading was altered a few degrees to the right and the approach was continued in light to moderate turbulence with the rain intensity increasing to heavy as the aircraft approached the runway threshold; the windscreen wipers were then selected to operate at high speed. At approximately 200-250 feet above terrain and prior to reaching the runway threshold, on the command of the Captain, the First Officer initiated a go-around because the aircraft had drifted too far to the left of the runway centre-line to safely effect a landing. The First Officer placed the power levers in the position for maximum power and he rotated the aircraft, by reference to the flight instruments, to the normal body attitude of 8 to 9 degrees for initial climb. The response of the engines appeared normal to the crew and they believed that full 'wet' power was being developed. Immediately after the engine power increased the captain raised the wing flaps from the setting of 26.5 degrees to 16.5 degrees, and he retracted the landing gear. At the commencement of the go-around the aircraft was still in conditions of turbulence and heavy rain and that, initially, the aircraft maintained its altitude; the indicated airspeed then decayed rapidly to 73 knots at which time the aircraft was estimated to be 80-100 feet above the runway. As the indicated airspeed decreased the First Officer lowered the nose of the aircraft slightly but still maintained a climbing attitude. At about this time the captain took hold of his control wheel but the First Officer continued to fly the aircraft by reference to his flight instruments. The indicated airspeed remained at 73 knots for a few seconds then rapidly increased to about 80-85 knots; it was not fluctuating and the turbulence had ceased. The rear fuselage of the aircraft then impacted the ground heavily just outside the boundary of the flight strip, at a point 1240 metres north of the runway 35 threshold, 48 metres to the right of the runway centre-line. The aircraft slid along on the fuselage for a distance of 625 metres during which the starboard engine was torn out of the wing. Cockpit impact drill was initiated by the flight crew during the ground slide and completed when the aircraft came to rest. The crew and passengers evacuated the aircraft at which time there was little or no rain at their location and there was a light breeze from a southerly direction.
Probable cause:
During the climb performance of the aircraft was adversely affected by an unpredictable encounter with a large change in the horizontal wind component, and an associated downdraft, at a height too low to effect recovery.
