NATA's Safety 1st Professional Line Service Training (PLST) program sets the standard for line service training. AMR Combs created the first training program for line service specialists in the mid-1980s. In the late 1990s, the Aviation Training Institute (ATI) produced a new video edition of PLST. NATA purchased ATI's PLST in 2000, improved it again, and subsequently introduced it under the NATA Safety 1st brand of line service training tools. That version of the training is used today by more than 1,100 FBOs and thousands of line service specialists across the United States and internationally.
 
Since the launch of the NATA Safety 1st and the introduction of PLST, we have released numerous other online training tools for all general aviation businesses. With the support of our customers and our NATA members, we are only getting better!
