Definition
The manufacturer (make) and the specific designation (model) that together identify a particular aircraft engine. The make names the company that built the engine, and the model identifies the exact configuration, displacement, power rating, and design variant within that manufacturer's product line.
Plain English
Who built the engine and exactly which version of their engine it is. For example, the company that made it, plus the specific name or number that tells you which one of their engines you have.
Context Anchor
Seen in aircraft maintenance records, logbook entries, inspection forms, engine data plates, and parts or service information.
Derivation
Make comes from the idea of who made something, and in this use it means the manufacturer. Model means a particular design or version made by that manufacturer. Together, the words narrow the engine from a general kind of engine to the exact one being discussed.
Why Pilots Care
Ensures that maintenance procedures, inspections, and performance calculations are performed correctly for the specific engine installed.
Intuition Check
Do not read “make and model” as a casual description like “an airplane engine.” Here it means the exact manufacturer and exact model designation used to identify the engine officially.
Example Sentence 1
Before ordering parts, the technician confirmed the engine make and model from the data plate on the accessory case.
Example Sentence 2
Before flight, verify that the engine make and model matches the one listed on the aircraft's type certificate data sheet.
