Narrative:

During the roll-out phase of landing on runway 30R; a taxiing widebody transport on the taxiway right turning left onto taxiway D jet blasted the single engine aircraft that I was acting as the CFI in. The aircraft did become momentary airborne and the tail of the aircraft was pushed strongly to the left. I did manage to keep control of the aircraft and prevented any damage to the runway or the aircraft. ATC did not advise or seem to notice the hazard of this jet-blast to the runway. The widebody transport was taxing slowly around the turn and could be possible he was using one engine to taxi with a lot of power in the turn. I believe that if this was not an experience pilot that had control of the aircraft; such as a student pilot; the outcome could have been worst. I can only imagine what the outcome could have been if we was still airborne. I think that the airport should not allow these aircraft to taxi with one engine. Another idea is to make sure ATC does not allow anyone to land near the widebody size aircraft when this type of hazard is possible until the aircraft is at a considerable distance. Another idea is not let this size of aircraft use those taxiways when 12L/30R is in use and traffic has clearance to land or take off. I do have a lot of experience working around this airport and preventing jet blast from aircraft to ours. I will inform students and pilots around the school of the newly discovered hazard at this airport and advise them to not land on that runway if this hazard does seam to exist. This was an unexpected event of jet-blast. Other weather information; wind was reported calm.
