Narrative:
We were cleared to intercept the lda prm 28R to san francisco following a heavy jet on the ILS prm 28L. We were instructed to maintain 180 KTS to darne and contact the tower there. At darne we contacted the tower and advised traffic ahead and runway in sight; and were subsequently cleared to land. On short final; approximately between 100 and 200 ft; we encountered wake turbulence from the heavy jet. Prevailing wind at the time was from approximately 30 degrees to the left of the nose at about 8-10 KTS. This condition probably caused the heavy's wake to be blown toward our flight path. Upon encountering the wake turbulence; we executed a go-around and returned for a standard ILS approach to 28L.
Original NASA ASRS Text
Title: An A320 crew on a 28R PRM reported going around between 100 and 200 FT after encountering wake turbulence from a heavy aircraft which was landing on a 28L PRM. A 10 KT left 30 degree crosswind was present during this event.
