An emergency airworthiness directive from the Federal Aviation Administration (FAA) with operational implications for aircraft assembled in Canada, operating in the United States, was issued with immediate effect following a presidential instruction on the certification status of these aircraft.
An emergency measure, which grounds aircraft on the next available landing, unless otherwise exempted, indicates a move towards a rulemaking process, as discussed below, which outlines the determinations and provisions made, reproduced verbatim for reference purposes.
Emergency Airworthiness Directive (AD) 2026-01-266 is sent to owners and operators of all aircraft whose final assembly was completed in Canada.
The President of the United States has instructed that the type certificate for all aircraft whose final assembly was completed in Canada, as referenced under 14 CFR § 121.571(b) and 14 CFR § 135.117(e), be revoked with immediate effect.
These products have been approved by the aviation authority of another country and were approved for operation in the United States. The FAA is issuing this emergency AD after determining that this approval basis has been revoked.
This emergency AD requires operators to immediately cease operations of affected aircraft upon their next landing, except for any authorization specifically granted by the FAA.
