Canberra – An Australian Transport Safety Bureau preliminary report suggests that a helicopter’s communication systems may have critical problems, including a malfunctioning antenna which may have contributed to a Queensland helicopter crash earlier this year that resulted in five fatalities.
According to the report, the transport board problem statement signaled an emergency situation that should have activated procedures for sending out SOS alerts immediately and receiving them via a rotary ELT system fitted onto the aircraft. Without visibility to air traffic control as the helicopter was high up in Gulf Country, the vessel achieved low altitude navigation during contact.
The Gulf Country area contains notable geographical features known for their abrupt steep breaks. The aircraft is believed to have had two Bell212 helicopters. Toward the parting flight of the aircraft, the contact with the vessel is believed to have transmitting alerts for “Transponder contact on Gulf alpha one twenty two” that aid in plane “traverse navigation”.
Breakdowns in Communication
As stated by Angus Mitchell, ATSB Chief Commissioner, “The ELT System was unable to transmit a functional signal because of a faulty antenna connection,” and he continued, “This drastically reduced the capacity of the air craft to ALERT search and rescue teams at such a vital point during the emergency.”
Also, it was noted in the report that the weather was harsh and the pilot had restricted sight throughout the flight. However, failure of communication was emphasized as one of the most dominant reasons for both the delayed response and the crash.
Response from the Industry
The Australian aviation industry as a whole is undergoing increased scrutiny ever since the incident. Particularly from aviation operators who manage older planes located in remote regions of Australia. A review regarding the operational protocols and the standards of equipment for helicopters under commercial and government use was proclaimed by CASA (Civil Aviation Safety Authority).In a statement, CASA has said that “We are working closely with the ATSB to ensure that similar failures do not happen again.” In the same release, they stated that “All operators are being urged to conduct immediate inspections of ELT systems and antenna fittings.”
Families Demand Answers
Emma Kerr, whose sibling was a victim, stated: “Our loved ones might have been saved if help arrived sooner. We need stronger checks and real consequences when safety is compromised.” This highlights the demands being made by family members with regards to some degree of accountability being put in place and better safety regulation enforcement, especially on the ageing aircraft operating in the Outback.
In the meantime, The ATSB is anticipated to issue a comprehensive final report later this year which is likely to detail further proposed changes to aviation safety policies.
