Definition
An aircraft whose design has been formally approved by the FAA through the issuance of a type certificate, confirming that the design meets the airworthiness standards in the applicable Federal Aviation Regulations. Each individual aircraft built to that approved design is then issued its own airworthiness certificate, and the aircraft must be maintained in accordance with the type certificate data sheet and approved manuals.
Plain English
An aircraft built to a design that the FAA has officially approved as safe to fly. The whole design has been reviewed and signed off, and every aircraft made to that design must be kept in the condition that approval requires.
Context Anchor
You may see this term when reading about which older or existing aircraft can qualify to be flown under light-sport aircraft rules.
Derivation
From 'type' (a category or model of aircraft) and 'certificated' (formally approved by issuing a certificate). A type certificate covers the design itself — the 'type' — rather than any one airplane.
Why Pilots Care
Determines the operating rules, maintenance requirements, and pilot qualifications that apply to the aircraft.
Intuition Check
Do not read type certificated aircraft as simply “an aircraft with paperwork.” Here, type refers to the FAA-approved design or model, and certificated means that design has received formal FAA approval.
Example Sentence 1
Most training airplanes at flight schools, such as the Cessna 172, are type certificated aircraft built to an FAA-approved design.
Example Sentence 2
Before a flight school adds an aircraft to its fleet, it confirms the model is type certificated to meet insurance and regulatory standards.
