Ground Event / Encounter Other / Unknown; Inflight Event / Encounter Loss Of Aircraft Control
Flight Crew Regained Aircraft Control
Environment - Non Weather Related; Procedure
At 50 FT [AGL] on landing at BOS on a visual approach Runway 04L; encountered a significant rolling motion caused by jet blast from a heavy aircraft that just departed from Runway 09. By the time I was able to correct the rolling motion we were through it and still on a visual glidepath for our landing runway. I continued for an uneventful landing and rollout. Tower was notified after we landed.Suggestions: Tower can not depart aircraft on Runway 9 with an aircraft on very short final for Runway 04L.
Captain was flying on visual approach to [Runway] 4L at BOS. At approximately 50-100 FT we experienced a significant rolling motion. Large Airbus was on the departure roll Runway 9. Captain regained control of the aircraft and we made a landing within the first 1/3rd of runway. Roll was very significant and we were very close to the ground.I was under the impression that aircraft are not departed on perpendicular runway when aircraft are landing such as in this situation. If this is not the case then it should be.
B737-800 flight crew reported encountering a rolling motion at 50 FT AGL on approach to BOS Runway 4L they felt was caused by jet blast from a heavy Airbus departing on Runway 9.
