If a repair station provided me a copy of their A449 paragraph with the notation ‘A2’ or ‘A3’ in the telephone field, what else do I need to verify they conduct federal drug and alcohol testing?

View the full FAQ here.

The ‘A2’ designation on an Operations Specifications paragraph (A449) for a repair station is used when the safety-sensitive employees are part of a combined contractor registration. If the repair station’s A449 paragraph has an ‘A2’ notation, you should request a copy of the program registration that lists the repair station’s certificate number.  

The ‘A3’ designation on a repair station’s A449 is used when the safety-sensitive employees are part of a combined program with an air carrier or air tour operator (as defined in 14 CFR § 91.147). If the repair station’s A449 paragraph has an ‘A3’ notation, you should request a copy of the part 121, 135, or 91.147 operator’s A449 paragraph or Letter of Authorization (LOA or A049) from the employer that is responsible for testing and the employee’s safety-sensitive duties.
