NTSB ISSUES UPDATE ON NEAR COLLISION ON ALLENTOWN RUNWAY

November 19, 2008

In its continuing investigation of a runway incursion in Allentown, Pennsylvania, involving a general aviation aircraft and a Chicago-bound regional jet airliner, the National Transportation Safety Board has developed the following factual information:

On September 19, 2008, at 7:38 p.m. EDT, a runway incursion resulted in a near-collision on runway 6 at the Lehigh Valley International Airport, Allentown, Pennsylvania.  Mesa Air Shuttle flight 7138, a Canadair CRJ-700 (N506MJ) aborted takeoff at about 120 knots (138 mph), skidding around a Cessna R172K (N736GV) that had just landed and was still taxiing on the runway.  The crew of the Mesa Air regional jet estimated the distance between the two aircraft as 10 feet when they passed. 

The Mesa Air flight carried 56 passengers and a crew of four; the Cessna carried a pilot and two passengers.  There was no damage to either aircraft and no reported injuries.  The incident occurred in night meteorological conditions.

A timeline of the incident events is as follows:

The Mesa Air crew elected to cancel the flight and have the aircraft inspected.  The Cessna taxied to general aviation parking and concluded the flight.

Safety Board investigators have interviewed the pilots involved in the incident, and the air traffic controllers on duty at the time of the incident as well as the FAA tower managers.

The tire marks created by the Mesa Air regional jet as it veered around the Cessna can be seen on the left side of the centerline in the image below.
