澳大利亚国防军四名成员在2023年7月一次训练演习中驾驶MRH-90 Taipan直升机坠入昆士兰州惠特桑迪群岛海域，四人全部遇难[1]。遇难者分别为Captain Danniel Lyon、Lieutenant Maxwell Nugent、Warrant Officer Class 2 Joseph "Phillip" Laycock和Corporal Alexander Naggs[1]。事故发生时直升机时速达259km/h[1]。这起坠机事故已引发多项调查，包括一项于2023年10月启动、历时15个月的独立调查[1]。
遇难者家属现已对澳大利亚政府和空中客车公司提起集体诉讼，声称相关失职导致了他们的死亡[1]。家属指控涉及TopOwl夜视仪软件升级存在的问题[1]。根据防御飞行安全局2024年5月发布的报告，退役测试飞行员Major Ian Wilson曾在2020年向陆军发出警告，称TopOwl 5.1存在严重故障，可能构成"工业过失杀人"[1]。该系统的夜视能力比其他系统低50%[1]。领导此次诉讼的是遇难者之一Danniel Lyon的遗孀Caitland Lyon[1]。家属表示提起诉讼的原因是"停止时钟"以防止失去诉讼权利[1]。
Families of four Australian Defence Force members killed in a helicopter crash have initiated legal proceedings against the Australian government and Airbus, alleging negligence contributed to their deaths [1]. The four service members—Captain Danniel Lyon, Lieutenant Maxwell Nugent, Warrant Officer Class 2 Joseph "Phillip" Laycock, and Corporal Alexander Naggs—died when their MRH-90 Taipan helicopter crashed into waters off the Whitsunday Islands in Queensland during a training exercise in July 2023 [1]. The aircraft was traveling at 259 kilometers per hour at the time of impact [1].
The lawsuit centers on claims of systemic failures, including alleged defects in the TopOwl night vision system software upgrade [1]. A retired test pilot, Major Ian Wilson, had warned the military in 2020 of serious malfunctions in the TopOwl 5.1 system that he suggested could constitute "industrial manslaughter," and testing revealed the system's night vision capability was 50 percent below that of comparable alternatives [1]. An independent investigation into the accident, launched in October 2023, was completed in May 2024 after 15 months [1]. The class action was filed to prevent families from losing their legal rights under the statute of limitations, with Caitland Lyon, widow of Captain Danniel Lyon, leading the proceedings [1].
