The ATSB is investigating a propeller malfunction involving Bombardier DHC-8-202, VH-ZZA, which was conducting aerial work near Darwin, Northern Territory on 3 December 2019.
During climb, a loud bang was heard and debris was witnessed flying past the aircraft window. All systems were operating normally and the crew elected to continue the flight, which was completed without further incident. Post-flight inspection discovered damage to the right side of the fuselage and the right propeller. A propeller blade cuff from the right propeller was also missing, which was determined to have separated in flight and resulted in the damage to the aircraft.
As part of the investigation, the ATSB will review the relevant maintenance information and examine previous instances of blade cuff failures on this aircraft type.
A report will be released at the end of the investigation. Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant stakeholders so appropriate and timely safety action can be taken.
