Incident at CALGARY INTL AB (CYYC)

Summary

2003-01-09: Shortly after departure at Calgary, WJA 500, a Boeing 737-700, struck a bird with the left engine. The engine was not shut down, but the crew returned to Calgary as a precaution.
2003-01-17: UPDATE Aerodrome Safety reported that the YYC Environmental Specialist advised that on January 9, 2003 at approximately 0740 local time, WJA 500, a B737-700 struck a short-eared owl on rotation while on departure on Runway 34. The short-eared owl struck the left engine cowling and the pilot elected to have the aircraft return to YYC for inspection. Calgary Airport Authority Wildlife Staff were on duty at the time of the strike and conducted a runway inspection immediately after the incident. The remains were discovered and returned to the Environmental Specialist for proper identification. After the incident, the Wildlife Control person met the aircraft on its return to the gate location at 0820 to determine the extent of damage. At this time, no determination could be made until a boroscope inspection could be completed. The next day, WestJet was contacted and they explained that the strike did not cause any damage. It should be noted that the aircraft inspection required 25 man hours, plus downtime for the aircraft, as well as the inconvenience to put the passengers onto a different aircraft. The Calgary Airport Authority has a comprehensive Wildlife Management Program. Wildlife Control personnel are on duty every day of the year from 0600 until 2200. At the time of this strike, light conditions were dark, which limited any type of active control measures. The species of owl struck is not normally observed around the airport at this time of year which also made it difficult to anticipate. It is believed the bird, most likely, was traveling through the area when it ventured airside. The Airport Authority will continue to patrol and monitor the area for any further evidence of this species and if necessary take the appropriate mitigation measures. RECOMMENDATIONS: Calgary airside operations through their Wildlife Control Program has a strong focus on pro-active management which includes primarily habitat elimination. They also have a significant active control component which includes pyrotechnics and various exclusion and deterrent methods. No further action is required.
