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.

Safety Management

Safety is the first priority in all our activities. We are committed to implementing, developing and improving strategies, management systems and processes to ensure that all our aviation activities uphold the highest level of safety performance and meet national and international standards.  We manage safety in a systematic, organised way in order to minimise risk.  We operate in accordance with our organisational safety system manual and provide our staff with regular safety education and training. Monitoring all civil aviation orders (CAO’s) and civil aviation advisory publications (CAAP’s) ensure our compliance with all safety regulations.

It includes social and personal skills such as communication and leadership, as well as the physical and psychological factors that influence interaction with our environment. Human Factors are considered in conjunction with technical skills, both of which are important for safe and efficient aviation.


Drug & Alcohol Management Plan (DAMP)

The Walsh Avionics Drug & Alcohol Management Plan (DAMP) amalgamates two components of CASR Part 99 Alcohol and Other Drugs Management and testing in aviation.  Those components being sub-part B ‘Drug and Alcohol Management Plan (DAMP)’; and sub-part C, applicable only to those personnel defined by CASA as being in Safety Sensitive Aviation Activity roles, ‘CASA Alcohol and Other Drug Random Testing Guidelines’.
