Bird Strikes – an Increasing Safety and Economic Concern

Bird strikes are an increasing safety and economic concern, annually costing commercial air carriers over $1.2 billion USD

Learjet 45 strike with pigeons at Linate Airport, Italy, June 2003. Aircraft and building destroyed, two pilots killed.

1. Increasing populations of large- and flocking- bird species.
2. Faster quieter turbofan-powered aircraft.
3. Non Bird Strike resistant airframes and engines, relative to large- and flocking-bird species.

Amendment 10 to Annex 14, Volume I

•9.4 Wildlife strike hazard reduction
•Note.—The presence of wildlife (birds and animals) on and in the aerodrome vicinity poses a serious threat to aircraft operational safety.

Amendment 10 to Annex 14, Volume I

•9.4.1 The wildlife strike hazard on, or in the vicinity of, an aerodrome shall be assessed through:
a) the establishment of a national procedure…
b) the collection of information from aircraft operators, aerodrome personnel….
c) an ongoing evaluation of the wildlife hazard by competent personnel.

•9.4.3 Action shall be taken to decrease the risk to aircraft operations by adopting measures to minimize the likelihood of collisions between wildlife and aircraft.

•9.4.4 The appropriate authority shall take action to eliminate or to prevent the establishment of garbage disposal… unless an appropriate wildlife assessment indicates that they are unlikely….. 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.

•9.4.5 Recommendation.— States should give due consideration to aviation safety concerns related to land developments in the vicinity of the aerodrome that may attract wildlife.
