At 1340 hours EST on 18 August, 1974, a parachutist was fatally injured on impact with the ground following a free fall parachute descent at Wilton, NSW. The parachute was observed to extend fully from the pack, but the canopy, which was squidding, failed to inflate.

At approximately 1822 hours Eastern Standard Time (EST) on 31 May 1974 Fokker Friendship F-27-100 aircraft, registered VH-EWL, crashed adjacent to Runway 35 at Bathurst aerodrome, New South Wales, during an attempted go-around from a landing approach. 

The aircraft came to rest after sliding 625 metres from the impact point and sustained substantial damage. 

VH-EWL was engaged in operating a regular public transport flight with a crew of four and was carrying thirty passengers. Both members of the flight crew, and six passengers, received minor injuries; no other persons were injured.

Parts of the tail plane were found in an area 550 metres from the main wreckage. Examination of these parts revealed evidence of failure as a result of in-flight loads being experienced in excess of their ultimate structural strength. There was no evidence of any pre-existing structural deficiency in the failed components. The nature and direction of the tailplane failures show they could only have occurred in a grossly abnormal condition of flight such as a complete loss of control. Very active thunderstorms were reported in the area at about the estimated time of the accident. These could have Induced a loss of control arising either from pilot disorientation in cloud or an upset in severe turbulence.

At approximately 1537 hours Eastern Standard Time (EST) on 13 March 1974, a De Havilland Dove DH1D4 Series 5 aircraft, registered VH-WST, and a Piper Twin Comanche PA30-160B aircraft, registered VH-WWB, collided in flight above a point 3 225 metres north of Bankstown Airport, Sydney, New South Wales.

The Dove aircraft had taken-off from Bankstown Airport and was orbiting the airport at about 1 500 feet above terrain before proceeding to Sydney (Kingsford-Smith) Airport. Some two minutes later the Twin Comanche aircraft also took-off from Bankstown Airport and was proceeding to a training area in the vicinity of Camden. The collision occurred in the Bankstown Control Zone in visual meteorological conditions (VMC), and both aircraft were operating under the Visual Flight Rules (VFR).

Following the mid-air impact, both aircraft fell to the ground in a residential area of the suburb of Bass Hill, causing damage to houses and other property. The sole occupant of the Dove aircraft and the three occupants of the Twin Comanche aircraft were killed. Both aircraft were destroyed by the collision and ground impact.

At approximately 1445 hours, EST, on 29 December, 1974 a Cessna 172K aircraft, registered VH-KUE, crashed into the sea some eight kilometres north of Slade Point, Queensland. The bodies of two of the three occupants of the aircraft and portions of the aircraft wreckage were subsequently located and recovered from the sea.

At approximately 1045 hours EST on 25 April, 1974 a parachutist was fatally injured on impact with the ground following a free fall descent near Beaudesert, Queensland. Examination of the equipment after the accident revealed that the main parachute had been activated and there was nothing to suggest it would not have fully deployed if there had been sufficient time and height available. The reserve parachute was intact and had not been activated. There was no evidence of any defect or error in the packing of either parachute which might have contributed to the accident. Examination of the altimeter did not indicate any defect which might have affected its normal operation prior to the accident.

The main rotor blades made contact with objects on the deck of the barge and three bystanders were struck by flying debris. The helicopter then fell into the water and subsequently the pilot swam clear of the wreckage. The cause of the accident was that the helicopter was operated in unsafe proximity to the barge.

On 16 February, 1974 a Beech 95/B55 Baron aircraft registered VH-FWR disappeared whilst on a flight from Gladstone to Longreach, Queensland, and no trace has been found of the aircraft or its two occupants.

The search for the aircraft continued on an intense scale until 25 February, 1974. During this time civil and military aircraft flew a total of 532 hours and searched an area in excess of 40,000 square miles, within which the areas of high probability were examined many times. Much of the eastern section of the search area consists of rough mountainous terrain covered with dense tropical vegetation. A number of sighting and hearing reports were received and investigated but the aircraft and its occupants have not been located.

At approximately 1830 hours Eastern Standard Time on 9 February, 1974, a parachutist was fatally injured on impact with the ground following a free fall descent at Mareeba Aerodrome, two kilometres south of Mareeba, Queensland.

The cause of the accident was that, following non-deployment of the main parachute, the reserve parachute canopy was seriously damaged when it inverted during deployment. There is insufficient evidence available to determine the reason for the canopy inversion.

At approximately 2020 hours EST on 4 January, 1974 a Beech 35/C33A "Debonair" aircraft, registered VH-DEW, struck the ground in conditions of heavy rain and darkness some 1400 metres north of Barkly Downs homestead, Queensland.

Examination of the wreckage subsequently established that the aircraft had struck the ground on a south-westerly heading, at high speed in a 20 to 30 degrees nose down attitude and while slightly banked to the right. The aircraft had broken up on impact and the wreckage trail extended about 137 metres beyond the point of initial ground contact. There was no evidence of any pre-impact structural failure, defect or malfunction which could have contributed to the accident.
