The Australian Transport Safety Bureau recommends that the Civil Aviation Safety Authority expand the requirements for the carriage and activation of transponders with the object of maximising the effectiveness of airborne collision avoidance systems.

Initial response

Response from: Civil Aviation Safety Authority
Action status: Monitor
Response text:

I refer to the draft ASO Report on the traffic confliction incident involving Beech 1900, VH-IMA, Beech 1900, VH-IMH, Piper PA-31 (Chieftain) VH-SVV, and De Havilland DHC-8-201 (Dash 8), VH-TQO, which occurred near Port Macquarie, NSW on 28 April 1999.

The Civil Aviation Safety Authority does not agree with recommendations R20000181 and R20000182, but supports recommendations R20000184, R20000198 and R20000199. R20000183 is still being considered.

CASA is, at this stage, still considering R20000183 and is currently reviewing mandatory requirements for the carriage and activation of transponders. Although the current level of transponder fitment in the Australian fleet is high, it is accepted that a higher level of fitment and mandatory requirements for activation of transponders where TCAS-equipped aircraft are operating would enhance safety.

ATSB comment:

As at 20 March 2008, no further advice had been received from CASA on their consideration of the recommendation and the ATSB reclassifies it is Closed - Not Accepted.
