Tell him to avoid American Eagle and AA. They don't give the time of day to anything with anything on their record, no matter what happened and who's fault it was. ExpressJet, Delta, Continental, Horizon, Air Wisconsin, and Northwest have concerns, but they'll interview and hire someone with an accident, incident, or occurrence on their record.
Just so ya know, some places are asking, “Have you ever been investigated by the FAA and/or NTSB?” If you ever had a ramp check, the answer is yes.
