Inflight Event / Encounter Wake Vortex Encounter
General None Reported / Taken
Procedure; Environment - Non Weather Related
[We were] landing [Runway] 36L MEM; visual approach. VFR conditions; winds 080/009. [We had] visual contact with traffic (heavy Airbus - A300) ahead and the field. Visual approach clearance received. Spacing between traffic [was] approximately 3.5 miles. Controller issued two cautions for wake turbulence. Upon crossing runway threshold my aircraft experienced wake turbulence approximately 100 FT above runway. Turbulence [was] not enough to warrant go around. Aircraft rolled approximately 10-15 degrees left and right. Any increase in wake and a go around would have been executed. Minimized spacing caused wake turbulence. Recommend re-evaluate decreased spacing.
Medium Large Transport Captain reported wake vortex encounter on approach behind an A300 that resulted in left and right roll 100 FT AGL.
