What happened
On the day of the incident, two aircraft collided at the intersection of two active runways. The Beechcraft 1900C, registered as N87GL, was performing its landing roll on runway 13. Simultaneously, a Beechcraft A90, registered as N1127D, was engaged in its takeoff roll on runway 04.
While the crew of the N87GL had attempted to coordinate their arrival via radio and visual observation, a misunderstanding occurred regarding the intentions of the aircraft on the intersecting runway. The crew of the Beechcraft 1900C heard a radio transmission from a third aircraft, a Cherokee, which stated that the pilot was holding for departure on runway 04. The crew of the N87GL incorrectly interpreted this transmission as a response from the N1127D regarding its departure plans. This led the crew to believe the Beechcraft A90 would remain stationary until the Beechcraft 1900C had exited the runway.
Findings
Investigation into the collision highlighted two primary communication issues. First, the pilot of the Beechcraft A90 did not broadcast his intention to depart on the common traffic advisory frequency. Second, the lack of a clear departure announcement from the A90 contributed to the confusion that allowed the aircraft to enter the path of the landing plane.
