Which Canadian maintenance entity may approve data for major repairs to US-registered aircraft?

• A. Transport Canada civil aviation maintenance engineer (AME)
• B. Transport Canada civil aviation approved maintenance organization (AMO)
• C. Neither A nor B
• D. Other Canadian entity

Answer: (C)

When a repair qualifies as major, the repair data used has to be approved by the authority that certifies airworthiness for that aircraft. For US-registered aircraft, that approval typically comes from the FAA or from a foreign authority that the FAA has recognized under a bilateral arrangement. A Transport Canada AME or a Transport Canada approved maintenance organization does not have authority to unilaterally approve engineering data for major repairs on US-registered airplanes, simply by virtue of being Canadian. In other words, Canadian entities cannot grant the necessary data approval for major repairs to US-registered aircraft; the approval must come from the FAA (or a recognized foreign authority under applicable agreements).
