Project AS 09/17 - New Advisory Circular - Wildlife Hazard Management at Aerodromes
AC 139-26 (0) has been finalised and is available on the CASA website.
On request from the Australian Aviation Wildlife Hazard Group (AAWHG), the Australian Transport Safety Bureau (ATSB) recently produced a report analysing bird strike data recorded between the years 2002 and 2006. The report stated that the number of reported bird strikes nearly doubled over this period from approximately 750 strikes recorded in the year 2002 to 1200 strikes recorded in the year 2006.

The report also referred to an estimate from the Federal Aviation Administration that the worldwide cost to aviation industry from wildlife strikes is approximately 1.3 billion dollars per annum.
The ATSB report stated that the quality of bird strike reporting is somewhat inconsistent with many bird strike events being inadvertently miscounted due to multiple and sometimes contradictory reports. Through feedback provided to the AAWHG members by the aviation industry, it is apparent that the correct classification and reporting of bird strikes is not consistent nationally.
The ATSB report further stated that over two-thirds of strikes events occur during the takeoff and landing phases of flight. Therefore any improvement to the management of wildlife at aerodromes has the potential to make a significant impact to the overall reduction of wildlife strikes.

As the regulator for civil aviation safety, CASA is in a position to make a positive contribution in this area through effective regulation, industry education and operational surveillance.
Under our current regulatory framework, Part 139 of the Civil Aviation Safety Regulations (CASR) requires that the operators of Certified and Registered aerodromes manage wildlife hazards at or in the vicinity of the aerodrome in accordance with the Manual of Standards (MOS) Part 139.
MOS Part 139 section 10.14 requires that the operator of a Certified Aerodrome must monitor wildlife activity and prepare a management plan. For the operator of a Registered Aerodrome, MOS Part 139 section 12.1.3 requires (at a minimum) that a check be made of the 'animal and bird activities' in the vicinity of an aerodrome.
Aside from these outcome statements in MOS Part 139, there is little information provided to an aerodrome operator detailing what CASA specifically expects in order to demonstrate compliance and how this can be achieved.
The aim of this new AC under CASR Part 139 is to:
- provide general information and advice to the management of wildlife at aerodromes in support of CASA's regulatory requirements under CASR Part 139 and MOS Part 139;
- establish a national 'recommended industry practice' for the consistent and accurate reporting of wildlife strikes by aerodrome operators to the ATSB;
- communicate the latest ICAO recommendations to the management of wildlife hazards at aerodromes; and
- communicate the latest AAWHG recommendations to the management of wildlife hazards at aerodromes
Following the issue of this new AC, it is probable that amendments to MOS Part 139 sections 10.14 and 12.1.3 may be required to align the information between both documents.
To assist with the content of the AC, the AAWHG has already developed a series of policy documents for the management and reporting of wildlife hazards. These policies have been developed over the past 5 years based on the experience and input from:
- Aerodrome operators;
- Air transport operators;
- Department of the Environment;
- Department of Infrastructure; and
It is proposed that these policies are reviewed internally by representatives within Airways and Aerodromes before being incorporated into this new AC.
The current ICAO recommendations for Wildlife Hazard Management should also be addressed in the new AC. The significant proposed changes to the current bird and wildlife standards as set out in Chapter 9 of ICAO Annex 14, Volume I include:
- Replacing the term 'bird strike hazard' with wildlife hazard;
- nclusion of guidance material to support the following ICAO standard: Action shall be taken to decrease the risk to aircraft operations by adopting measures to minimize the likelihood of collisions between wildlife and aircraft;
- Inclusion of the guidance material to support the following ICAO standard: The appropriate authority shall take action to eliminate or to prevent the establishment of garbage disposal dumps or any source which attracts wildlife to the aerodrome, or its vicinity, unless an appropriate wildlife assessment indicates that they are unlikely to create conditions conducive to a wildlife hazard problem. Where the elimination of existing sites is not possible, the appropriate authority shall ensure that any risk to aircraft posed by these sites is assessed and reduced to as low as reasonably practicable; and
- Inclusion of guidance material to support the following recommendation: States should give due consideration to aviation safety concerns related to land developments in the vicinity of the aerodrome that may attract wildlife.
