Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
A 'no brake condition' was experienced while the plt was using the yellow brake sys during a landing. The normal landing procedure calls for using the green sys. During the roll-out, the plt selected the emergency yellow sys & subsequently locked the brakes. He stated that the yellow hydraulic sys was used because of a problem with the green sys on the previous day. Also, he reported that management had decided to use the yellow sys. The specific level of management that had reportedly made this decision was not identified.
