Chapters & Procedures Covered

This manual systematically guides you through the entire overhaul process, providing clear instructions for every critical area of the blade.

• Introduction: General information, required publications (service bulletins/letters), personnel requirements, safe handling, facility and tooling requirements, component life and service definitions.
• Description and Operation: Overview of aluminum blades, blade and propeller model designation systems, identification of shank types (Y, D, E, X, V, MV, W, Z, M, P, R, T).
• Blade Shank Overhaul: Complete disassembly, cleaning, dimensional inspection, retention radius inspection (including optical comparator use), rework procedures for all single and double shoulder shanks, chemical etching, penetrant inspection, cold compression rolling, shot peening, and application of chemical conversion coatings.
• Blade Airfoil Overhaul: Blade station setup, straightening limits, grinding and polishing procedures, chemical etching, penetrant and eddy current inspection, dimensional inspection (thickness, width, length, angle, face alignment), blade length reduction rules, shot peened blade inspection and rework, Q-tip blade repair, lightning strike inspection, and blade anodizing.
• Special Inspections and Procedures: Mandatory inspections and repairs for specific applications, including hard alloy blade procedures, eddy current inspection requirements, modifications for double shoulder blades, Nord 262 aircraft inspections, counterweight requirements, blade shank inspection for T10176 blades, interchangeability of N modification blades, and many other special use cases.
• Finish: Blade painting, application of Teflon tape on Y, D, and E shank blades, application of hard coating on shank radius, installation of split bearing race and retaining ring, and application of lubricant.
• De-ice Boot: Relocation of electrical de-ice and anti-icing boot instructions to separate Hartzell manuals (with references).
• Blade Balancing: Static-horizontal and static-vertical balancing of blade sets with detailed procedures and lead wool installation.
• Illustrated Parts List: Comprehensive parts breakdowns for every shank type including bushings, bearings, spacers, plugs, and retention rings.
• Appendix A – Optical Comparator: Guide to using the optical comparator for shank radius inspection, approved comparator models, and overlay reference tables.
• Appendix B – Travelers: Sample overhaul and dimensional travelers for all major shank types, providing a workflow checklist for the overhaul process.
• Appendix C – Blade Specification Tables: Extensive tables with dimensional limits (width, thickness, face alignment, angles) for nearly every Hartzell aluminum blade model, along with tip specification drawings.
• Appendix E – Rolling Machine: Complete operating and maintenance instructions for the DT-1724-( ) blade cold rolling machine, including setup procedures for each shank type.

Technical Authority & Value

This is not a generic or aftermarket guide. It is the official engineering publication used by Hartzell Propeller Inc. and their authorized service centers. The procedures within are based on extensive engineering analysis and testing and include the latest revisions up to January 2017, as well as incorporated temporary revisions (TRs) concerning critical areas like blade shank rolling, balance hole shot peening, and blade specification limits for D, E, and other shank designs.

The manual empowers you to perform a complete, airworthy overhaul of a Hartzell aluminum blade from disassembly to final assembly. It covers critical processes such as compression rolling of the retention radius (requiring a certified DT-1724 machine), shot peening of the pitch change knob, and detailed optical comparator inspection of the highly-stressed shank radius. Using this manual ensures compliance with FAA regulations, service bulletins, and airworthiness directives, helping to prevent premature blade failure or unsafe conditions.
