CASA has mandated that all IFR aircraft must be equipped for ADS-B by 2 February 2017.  This applies to all Australian aircraft and will enhance AirServices' capability to provide safe and efficient air traffic management services.

All IFR Aircraft

On and after 2 February 2017, any aircraft that is first registered before 6 February 2014 and is operated under the IFR must carry serviceable ADS-B transmitting equipment that complies with Civil Aviation Order 20.18


Reporting & Investigation of Defects


ALL defects are recorded and reported to our Quality Manager.  Reported defects are evaluated and considered with respect to prior maintenance practices and processes and approved maintenance data including maintenance instructions and airworthiness directives.  In addition to the actions taken relating to each defect to maintain or restore airworthiness of the aircraft, defects meeting the definition of a Major Defect, are submitted to CASA pursuant to CAR 51A (1).  Special consideration is given in circumstances where defects are deemed ‘other than normal wear and usage’.

Walsh Avionics maintain its own records tracking of abnormal defects and obtain engineering advice other than from the aircraft or component manufacturer to plan remedial action.
