Where can you find a list of approved engines for specific aircraft models?

The Type Certificate Data Sheet (TCDS) is the correct source for finding a list of approved engines for specific aircraft models. The TCDS contains detailed information about the aircraft, including the approved engine types, weight limits, and specific airframe configurations. This document is critical because it defines the aircraft's certification and outlines the components that have been tested and approved in conjunction with the airframe.

By consulting the TCDS, mechanics and operators can ensure that they are using the correct engines that meet regulatory approval. This is essential for maintaining safety standards and compliance with Federal Aviation Administration (FAA) regulations. Understanding the approved engine list from the TCDS helps prevent the use of unauthorized or incompatible engines, which could compromise the aircraft's performance and safety.

Other documents like the Aircraft Technical Manual and the Maintenance Repair Manual may contain useful information about the aircraft and its maintenance procedures, but they do not specifically enumerate the engines approved for that aircraft. Meanwhile, the Federal Aviation Regulations (FAR) outline broader regulatory requirements rather than specific aircraft and engine combinations.
