I think it has already been said but HF should be aimed at everyone within an aircraft maintenance organisation and not just the engineers in the hangar. The guys and girls at the front end are high risk but other personnel from HR to the canteen staff should all be included. I know from experience that office based staff do not feel that they need to be HF trained as they feel that they have no involvement with maintenance, however it is usually the bean counters that are applying the pressure to complete the work and release the aircraft in the shortest space of time. Everyone within a maintenance organisation has a responsibility for HF and should undergo awareness training.
