Safety Recommendation

The Australian Transport Safety Bureau recommends that the Civil Aviation Safety Authority assess the safety benefit of mandating Saab Aircraft AB Service Bulletin 340-24-026 incorporating generator control unit modification number 2533.

Response from: Civil Aviation Safety Authority
Action status: Closed - Not Accepted
Response text:

CASA has assessed the safety benefit of mandating SAAB Service Bulletin 340-24-026 and can see no case for mandating modification 2533, which is essentially a product improvement.

The original issue of the Service Bulletin was given "recommended" status by the manufacturer. However, when the Bulletin was revised in October 2001, the status was downgraded to "optional". Therefore, given the downgrading of the manufacturer's status and the fact that this is a product improvement, CASA can see no safety benefit in mandating this Bulletin.
