The purpose of SAE AIR4174A is to provide management designers and operators with information to assist them to decide what type of power train monitoring they desire. This document is to provide assistance in optimizing system complexity performance and cost effectiveness.

This document covers all power train elements from the point at which aircraft propulsion energy in a turbine or reciprocating engine is converted via a gear train to mechanical energy for propulsion purposes. The document covers aircraft engine driven transmission and gearbox components their interfaces drivetrain shafting drive shaft hanger bearings and associated rotating accessories propellers and rotor systems as shown in Figure 1. For guidance on monitoring additional engine components not addressed herein (e.g. main shaft bearings and compressor/turbine rotors) refer to ARP1839.
