Definition
A specific model of light twin-engine general aviation aircraft manufactured by Piper Aircraft, known as the Seneca II. It is a six-seat, low-wing airplane powered by two turbocharged piston engines (the 'T' indicates turbocharged, and '200' refers to the rated horsepower per engine). It is commonly used for personal travel, business flying, and multi-engine flight training.
Plain English
A particular model of small twin-engine airplane made by Piper, called the Seneca II. It seats up to six people and has two turbocharged engines, one on each wing.
Context Anchor
Seen in FAA handbook examples, aircraft manuals, training materials, and discussions where the exact airplane model matters.
Derivation
Piper is the manufacturer's name. 'PA' stands for Piper Aircraft. '34' is the internal model number for the Seneca line. '200' is the horsepower of each engine, and 'T' indicates the engines are turbocharged.
Why Pilots Care
Knowing the exact model designation matters because performance numbers, weight limits, icing certification, and operating procedures are specific to that model. A PA-34-200T behaves differently from later Seneca variants with different engines or systems.
Intuition Check
Do not read Piper PA-34-200T as a general aircraft category. It is the exact model designation for one specific Piper Seneca version.
Example Sentence 1
The handbook used a Piper PA-34-200T as the example aircraft when describing how ice accumulation affects a light twin's climb performance.
Example Sentence 2
Preflight inspection of the Piper PA-34-200T included checking the wing and tail de-icing equipment.
