Definition
Helicopters certificated under 14 CFR Part 29, which sets the highest airworthiness standards for rotorcraft. They are typically larger, multi-engine helicopters built to stricter design, performance, and safety requirements than smaller helicopters certificated under Part 27 (normal category). Transport category is further divided into Category A (multi-engine with engine isolation and one-engine-inoperative performance guarantees) and Category B (single-engine or multi-engine without full Category A performance protections).
Plain English
These are the larger, more capable helicopters certified to the strictest safety and performance standards. They are built so that, in many cases, they can keep flying safely even if one engine fails.
Context Anchor
Seen in FAA instrument procedure requirements when a rule applies differently to helicopters that are certified in the transport category.
Derivation
"Transport" here refers to a certification category for aircraft intended to carry people or cargo with the highest level of airworthiness assurance. The same term is used for large airline-type airplanes certificated under Part 25. The label signals "built and tested to the toughest standards," not just "used for transportation."
Why Pilots Care
Determines which airworthiness standards, maintenance programs, and operational privileges apply to commercial helicopter flights.
Intuition Check
Do not read “transport category” as simply “a helicopter used for transportation.” Here, it means a specific FAA certification category with specific design and safety standards.
Example Sentence 1
Because the operator was flying a transport category helicopter, it qualified for the lower IFR takeoff minimums published for Category A operations.
Example Sentence 2
Operators of transport category helicopters must follow more rigorous inspection schedules than those flying normal category aircraft.
