About this file

This document is a Maintenance and Operations (M&O) Critical Safety Items list for the T701D engine used in the UH-60L/AH-64A helicopter systems. It identifies 47 parts designated as critical safety items requiring specific inspection, testing, and quality control requirements to ensure airworthiness and operational safety.

The document specifies detailed critical characteristics for each part, including dimensional tolerances, material specifications, inspection methods (such as fluorescent penetrant inspection, ultrasonic inspection, and white light inspection), hardness requirements, and surface condition standards. Key component categories include bearings (annular ball and roller types), turbine discs and blades (stages 3 and 4), turbine shafts and rotors, seals, nozzle assemblies, bushings, and shroud segments. Each part entry includes the part number, National Stock Number (NSN), nomenclature, Critical Safety Item (CSI) certification date, serial number requirements, engineering test requirements, fatigue and endurance testing requirements, and approved replacement sources identified by CAGE codes. General Electric Company (Aircraft Engine Business Group) is listed as the primary or sole approved source for maintenance and overhaul on all items; secondary approved sources such as SKF USA Inc, Timken Aerospace, Schaeffler Aerospace Canada Inc, and others are identified for specific bearing and component replacements. The list establishes mandatory production and quality standards ensuring that all critical safety components meet rigorous engineering specifications before installation or use in military helicopter power plant systems.
