A preliminary finding by the National Transportation Safety Board (NTSB) reveals that the JetBlue plane that blew out four tires at Sacramento International Airport on August 26 had its parking brake engaged during landing.
Recorded flight data shows that the parking brake on the Airbus 320-232 was engaged at an altitude of 5,100 feet and stayed on throughout the landing, causing the twin-engine jet to rapidly decelerate and sparking a minor tire fire.
After Flight 262 ground to a halt, the captain ordered an evacuation using emergency slides. Seven of the 86 passengers suffered minor injuries. The two pilots and three flight attendants were unharmed.
The NTSB said neither pilot recalled any abnormal indications or warnings associated with the braking system prior to landing.

There have been at least four near midair collisions involving commerical jets in the past six months, most recently on September 16, when US Airways A320 came within 100 feet of colliding with a cargo plane over Minneapolis-St. Paul.
