Definition
An official FAA document issued as part of an aircraft's type certification that records the approved specifications, operating limitations, and configuration details for a specific aircraft model. It lists items such as approved engines and propellers, fuel grades, weight and balance limits, airspeed limits, control surface movements, and any required equipment or placards. The TCDS is the formal reference for what the FAA approved when the aircraft model was certified.
Plain English
It's the FAA's official spec sheet for an aircraft model. It states exactly what the aircraft was approved as, what engines and parts it can use, and the limits it must be operated within.
Context Anchor
A pilot may see a Type Certificate Data Sheet when checking an aircraft’s approved configuration, maintenance-related records, or limits that come from the FAA’s approval of that airplane model.
Derivation
Type' refers to the specific make and model of aircraft. 'Certificate' is the formal FAA approval. 'Data Sheet' is the document listing the approved details. Together: the document holding the approved data for that aircraft type.
Why Pilots Care
Pilots and owners consult it to confirm approved weights, speeds, configurations, and any special limitations that apply to their aircraft.
Analogy
Think of it like the official specification label for a whole airplane design, not just one individual airplane. It tells what the approved design includes and what limits come with it.
Intuition Check
Do not read “type” as a loose category like “small airplane.” Here, “type” means a specific FAA-approved design, such as a particular make and model series.
Example Sentence 1
Before approving the engine swap, the mechanic checked the Type Certificate Data Sheet to confirm the replacement engine was an approved option for that model.
Example Sentence 2
During preflight planning the pilot confirmed that the installed propeller met the requirements listed on the Type Certificate Data Sheet.
