the pilot's improper in-flight planning/decision, which allowed the airplane (MD-11) to encounter wake turbulence from a larger/heavy jet airplane (Boeing 747), while on a short final approach for landing on a close-by/parallel runway with a staggered threshold. Factors relating to the accident were the staggered/off-set runway thresholds, which positioned the normal approach path of runway 24R below that of runway 24L; the steeper than normal final approach path; and the left crosswind, which resulted in wake turbulence drifting from the Boeing 747's approach path to the MD-11's approach path.
