Safety Recommendation

The Australian Transport Safety Bureau recommends that the Civil Aviation Safety Authority examine the circumstances surrounding this incident where Saab 340 aircraft can stall without warning in icing conditions and take appropriate action to ensure the safety of the Saab 340 fleet operating within Australia.

Initial response
Date issued: 25 February 2004
Response from: Civil Aviation Safety Authority
Action status: Closed - Accepted
Response text:

CASA will observe any developments by the aircraft manufacturer or other aviation regulatory authorities towards mandatory modification of Saab 340 aircraft to provide enhanced stall warning in icing conditions.

The Authority understands that Transport Canada requires enhanced stall warning in Saab 340 aircraft registered in Canada. However, CASA is not aware of any Service Bulletin or similar document offering this enhanced stall warning system for general availability.

In order to ensure that Saab 340 aircraft operators are aware of circumstances surrounding the incident, the Authority's airline offices will write to their Saab 340 operators advising that they review the Bureau's report and note the recommendations.

CASA is satisfied that both Rex and Hazelton have taken appropriate measures to address the deficiencies identified in the 'Local Safety Actions' at Section 4.2 of the report. For the information of the Bureau, CASA will determine if the specific issues identified in 'Local Safety Actions' have been applied by Macair during its next audit of the operator.

In addition, CASA plans to publish a series of articles on icing related issues in a future edition of Flight Safety Australia.
