Incident
A loss of separation occurred between two aircraft after takeoff. The controller had issued a takeoff clearance to Simmons 4085 to fly the runway heading. United 556 was next in line and received a clearance to fly a heading of 140 degrees after takeoff.
Sequence of Events
The pilot of United 556 did not immediately turn to the assigned heading of 140 degrees. The controller made several attempts to contact the flight but received no response. In an effort to prevent United 556 from overtaking the slower Simmons 4085, the controller instructed United 556 to stop its climb. However, by the time the climb was stopped, radar separation of 3 miles had already been lost.
Aftermath
The incident resulted in a loss of radar separation between the two aircraft. No further details regarding injuries, damage, or subsequent actions were provided in the source.
