FAA officials at a meeting last month told representatives from key industry organizations, including the Aeronautical Repair Station Association (ARSA), that guidance for a new drug testing rule would be released in “the coming weeks.” The new drug and alcohol testing rules, with a delayed effective date of October 10, pertain to maintenance contractors and subcontractors for Part 121 and 135 operators (FAR 135.251 and 135.253). According to ARSA, the guidance will focus on the definitions of maintenance and preventive maintenance in the FARs and on case-by-case determinations to advise whether the rules apply to specific employees or subcontractors.
