Jetblue A320 at Sacramento on Aug 26th 2010, brake fire on landing

The NTSB released their final report concluding the probable cause of the accident was:

The first officer’s inadvertent activation of the parking brake in flight, which led to the airplane abruptly stopping and all four of its main landing gear tires deflating, and his use of a nonstandard procedure to cancel the airplane's monitoring alert system.

The NTSB reported that 4 seconds prior to the engagement of park brakes at 5116 feet MSL the speedbrakes were operated, the switch of which is near the park brake switch. The NTSB analysed: "It is likely that the first officer inadvertently activated the parking brake at the same time."

After touch down the first officer pushed and held down the ECAM emergency cancel pushbutton, which was his typical procedure to preempt the autopilot disconnect audio. This action also cancelled, in part, visual indications associated with the activation of the park brake. The operator's procedures state to use the ECAM emergency cancel push button only in case of spurious master cautions. Examination of the aircraft showed no malfunction. The NTSB analysed: "If the first officer had not cancelled out most of the visual alert indications associated with the in-flight parking brake activation, it is likely that a visual warning would have alerted the flight crew to the in-flight parking brake activation."
