ATSB issues final report on in-flight loss of propeller involving Saab 340B

The Australian Transport Safety Bureau’s (ATSB) investigation into the in-flight propeller loss involving a Saab 340B was the result of a fracture of the propeller shaft on the right engine propeller gearbox (PGB).

The right propeller separated from the aircraft, with 16 passengers and three crew on board, while it was on approach to Sydney Airport from the south-west on 17 March 2017.

The ATSB found the fracture was due to a fatigue crack that originated in a propeller shaft flange dowel hole and spread through the shaft until it could no longer transmit the loads required to maintain the propeller on the aircraft. The NSW Police Aviation Support Branch undertook a search operation for the propeller four days later. The propeller was located in dense bushland at Revesby, and airlifted out.

The ATSB was unable to determine, conclusively, what caused the fatigue crack to occur.

Following the incident, the engine manufacturer, General Electric, and the airline, undertook a number of proactive safety actions, such as the release of new service bulletins and airworthiness directives, and changes to their maintenance regime, to reduce the risk of this event from occurring again.

Rudder trim caused Beech 200 King Air loss of control accident on takeoff, Melbourne

The Australian Transport Safety Bureau’s (ATSB) final report into the loss of control and collision with terrain involving a Beechcraft B200 King Air, highlights the importance of following a cockpit checklist.

During take-off from Melbourne-Essendon Airport, Australia on the morning of 21 February 2017, the aircraft diverged to the left of the runway centreline. Having reached a maximum altitude of 160 feet (49 metres) above ground level, the aircraft began to descend with an increasing left sideslip. The aircraft subsequently collided with the roof of a building in the Bulla Road Precinct Retail Outlet Centre of Essendon Airport. The aircraft was destroyed by the impact. The pilot and four passengers were fatally injured. Two people on the ground received minor injuries.

The ATSB’s investigation found that the pilot did not detect that the aircraft’s rudder trim was in the full nose-left position prior to take-off. The position of the rudder trim, which assists a pilot with controlling an aircraft’s movement around the vertical axis, resulted in a loss of directional control and had a significant impact on the aircraft’s climb performance.

In addition to the importance of using a checklist, this accident also emphasises the challenges associated with decision-making during critical stages of a flight.
