On March 4, 2008, a Cessna 500 Citation entered a steep descent and crashed after colliding in flight with a flock of large birds about 2 minutes after takeoff from Oklahoma City-Wiley Post Airport (PWA).
Following its investigation the National Transportation Safety Board issued ten new safety recommendations. These include recommendations for:
– the revision of bird-strike certification requirements;
– airports compliance with the requirements to perform wildlife hazard assessments;
– aircraft-specific guidance information for minimizing the severity of aircraft damage sustained during a bird strike;
– reporting of all wildlife strikes;
– inclusion of the operator and operating rules in flight plans;
– issuance of a written document that expressly describes the terms of carriage by Part 135 on-demand operators;
– improving FAA on-site inspector surveillance to detect improper charter operations;
In addition, the NTSB reiterated a safety recommendation to require all operators of aircraft equipped with a CVR make sure the CVR is functioning (A-06-23).
