Where can type design information for an R1830-92 engine be found when certificated under the Civil Air Regulations?

The correct choice regarding where to find type design information for an R1830-92 engine, when certificated under the Civil Air Regulations, is in the Aircraft Engine Specifications. This document contains critical details about the engine's design, performance, and operational limitations, which are essential for ensuring that maintenance and operations comply with regulatory standards.

Aircraft Engine Specifications typically include the type certificate data sheet, which outlines the engine's characteristics, requirements for operation, and any limitations imposed by the certification process. This specification serves as an authoritative source of information for mechanics and operators, ensuring that they have access to the most accurate and relevant data concerning the engine's design and performance criteria.

In contrast, Propeller Specifications generally focus on the propeller itself rather than the engine, while the Airframe Maintenance Manual is directed towards the airframe and how it supports various components, including the engine but without the detailed engine specifications. Component Repair Guidelines are specific to the repair and maintenance procedures for specific components but do not serve as the primary source for initial design specifications of the engine. Therefore, the Aircraft Engine Specifications is the essential document for understanding the type design information specific to the R1830-92 engine.
