The ATSB recommends that the European Aviation Safety Agency take action to increase the number of existing helicopters that are fitted with a crash-resistant fuel system or have an equivalent level of safety in respect of post-impact fire.
Advice from Airbus Helicopters
Although not in response to this accident, as part of their directly involved party response to the ATSB’s draft investigation report, Airbus Helicopters advised that a service bulletin detailing the retrofit of a crash-resistant fuel system (CRFS) to its AS350 B3/EC130 B4 model helicopters was available and in the progress of certification. Development of a technical solution to retrofit earlier AS350 B2 model helicopters with a CRFS had also commenced. Airbus Helicopters advised that once a retrofit was developed it would be possible to fit a CRFS to all AS350 models, since all early AS350 versions could be upgraded to B2 models via existing service bulletins.
Airbus Helicopters also advised that a CRFS was certified and available as an option for inclusion in newly-manufactured AS350 B3e model helicopters.
