The NTSB has started investigating another close call between an airliner and business jet that occurred on Friday at San Diego International Airport in California. The incident involved a Southwest Airlines Boeing 737 and a Cessna Citation XLS during daytime VMC.
Preliminary information indicates that San Diego tower cleared the 737 to line up and wait on Runway 27 also advising that the Citation traffic was on a five mile final and cleared to land. About two minutes later, with the airliner still on the runway but not cleared for takeoff, the Citation crew radioed the tower, asking if they were still cleared to land.
Possibly this call by the Citation crew helped alert controllers to the proximity of the two aircraft because they immediately issued go-around instructions for the Citation. The 737 subsequently departed and the Citation landed about 15 minutes later.
Executing the go-around, the Citation reportedly overflew 737 by about 100 feet.
On February 27, a Bombardier Learjet 60 and JetBlue Embraer E190 narrowly missed each other at Boston Logan Airport. According to the NTSB’s final report published earlier this month, despite acknowledging ATC instructions to line up and wait, the flight crew of the Learjet 60 took off without clearance and caused a near-collision with thelanding Embraer E190, which passed over the business jet at about 400 feet after it was instructed to go around.
