What happened
At night, a Bombardier CL-600 Regional Jet (CRJ) was positioned at a taxiway split, where one taxiway branches into two. The aircraft was stationary with its parking brake set as the crew waited for preceding aircraft to clear the path ahead on one of the taxiways.
During this time, a Boeing 727 attempted to maneuver behind the CRJ, passing obliquely using the other available taxiway. The captain of the Boeing 727 was aware of the CRJ's position and believed there was sufficient clearance to pass safely. As the Boeing 727 proceeded along the taxiway centerline, the crew experienced a slight physical bump, which they initially attributed to a seam in the concrete pavement.
Shortly after the sensation, the Boeing crew heard the CRJ crew report an impact over the radio. The investigation confirmed that the left wing of the Boeing 727 had struck the right winglet of the Bombardier CRJ. The collision occurred from an aft-to-forward direction. There were no injuries reported following the contact.
