Safety Action

Summary

Although the Civil Aviation Safety Authority (CASA) implemented training programs to educate the industry on the hazards associated with low level helicopter operations, it is believed that WSPS kits may yet prove beneficial in mitigating helicopter wire strike accidents.

As a result of this investigation, and after a review of the ATSB accident database statistics relating to agricultural helicopter wire strike fatal accidents, the ATSB is concerned that fatalities are continuing to occur in agricultural helicopter operations despite the earlier recommendation (R19950120). The ATSB therefore issues the following recommendation.

R20010083

The ATSB recommends that CASA:

(i) Require the fitment of approved Wire Strike Protection System kits for all helicopters engaged in low flying activities for which a kit exists; and

(ii) That only agricultural spray kits compatible with Wire Strike Protection Systems be approved for fitment to these helicopters.
