Analysis

The acft went off the rwy during landing. The excursion was to the left & was not corrected before the acft made an exit from the rwy. The captain, in a written statement, said that he was anticipating a right x-wind because he was landing on rwy 26L & the wind was from 020 degrees at 12 KTS. He had already aborted a landing on rwy 17 due to a tailwind. The captain of another acft which landed in front of the incident acft reported a right x-wind. An FAA inspector, qualified in Boeing 727 acft, duplicated all conditions of the incident in a simulator and concluded that the incident was the result of improper technique or corrective action or a delay in response.
