Accident highlights the risks of aerobatic flight in a non-aerobatic aircraft and without adequate training.
The helicopter was departing from Bilingurr, about 2 km north of Broome Airport, with the pilot and three passengers on board. Soon after lifting off, the helicopter collided with terrain. The pilot and one passenger were fatally injured and the other two passengers were seriously injured.
The Cessna 208B was on its flight planned track from Cairns to Redcliffe, Queensland at flight level 110, when the pilot first contacted Brisbane air traffic control. The controller lost contact with the pilot 10 minutes later and the aircraft overflew its planned destination. The controller suspected the pilot had become incapacitated and another aircraft followed the 208B in an attempt to gain contact with the pilot.
During winching operations, the helicopter's main rotor blades struck a tree. The crew returned to Archerfield, after which inspection revealed substantial damage to all main rotor blades, which were replaced by engineers.
During descent, the pilot detected an airspeed mismatch between the pilot and co-pilot primary flight displays (PFD) and elected to return the aircraft to Jandakot.
A freight train unexpectedly encountered and entered floodwaters across a rail bridge near Tully, Queensland, highlighting the importance of weather monitoring stations at known flood locations being serviceable.
Visual flight rules pilots pressing on into instrument meteorological conditions without a current instrument rating carries a significant risk of spatial disorientation due to powerful and misleading orientation sensations with reduced visual cues.
» Disorientation can affect any pilot, no matter what their level of experience.
» Avoid deteriorating weather by conducting thorough pre-flight planning.
» Use a ‘personal minimums’ checklist to help control and manage risk.
» If you become disoriented or lost in marginal weather, seek whatever help is available, including support from air traffic control.
