FOR IMMEDIATE RELEASE: June 26, 2002 SB-02-19
EXCESSIVE AIRSPEED AND FLIGHT PATH ANGLE CAUSED SOUTHWEST AIRLINES B-737 RUNWAY OVERRUN IN BURBANK, CALIFORNIA, NTSB SAYS
Contributing to the accident was the air traffic controllers positioning of the airplane, which was too high, too fast, and too close to the runway threshold. As a result, no safe options existed for the flight crew other than a go-around maneuver. Furthermore, had the accident flight crew applied maximum manual brakes immediately upon touchdown, the airplane would likely have stopped before impacting the blast fence, the Board found.
A stabilized approach is critical for a safe landing, said NTSB Chairman Marion Blakey. Everyone involved in the system has an important role to play. The controller must establish the aircraft correctly on approach, the flight crew must adhere to stabilized approach criteria, and the airport operator needs to ensure an adequate runway safety area.
On March 5, 2000, Southwest Airlines, Inc., flight 1455, a Boeing 737-300, N668SW, overran the departure end of runway 8 after landing at Burbank-Glendale-Pasadena Airport, Burbank, California. The airplane touched down at approximately 182 knots. About 20 seconds later, at approximately 32 knots, the airplane collided with a metal blast fence and an airport perimeter wall. The airplane came to rest on a city street near a gas station off of the airport property. Of the 142 persons on board, 2 passengers sustained serious injuries, 41 passengers and the captain sustained minor injuries, and 94 passengers, 3 flight attendants, and the first officer sustained no injuries. The airplane sustained extensive damage and some internal damage to the passenger cabin.
During its investigation, the Board found that a forward service door escape slide inflated inside the aircraft and blocked the forward exit. This slowed down the evacuation from the plane.
Consequently, the Safety Board issued recommendations asking the FAA to issue
an airworthiness directive to require all operators of Boeing 737-300 through
-500 series airplanes to replace the slide cover latch brackets on forward slide
compartments with the type of slide cover latch brackets installed on the forward
slide compartment of Boeing 737-600 through -900 series airplanes. The Board
also issued a recommendation asking the FAA to issue an airworthiness directive
to require initial and periodic inspections of the pivot bracket assemblies
on a particular model jumpseat installed on Boeing 737-300 through -500 series
airplanes. Although a flight attendants jumpseat collapsed during the
accident, it did not affect the ability of passengers and crewmembers to evacuate
the plane.

The full report will be available on the web site in the next few weeks.
