UH-60A EH-60A UH-60L Black Hawk Airframe Depot Maintenance Modification Kits Manual – DMWR 1-1520-237-3 Appendix E

Description

UH-60A / EH-60A / UH-60L Airframe Depot Maintenance Modification Kits Manual

This is the UH-60A EH-60A UH-60L Black Hawk Airframe Depot Maintenance Modification Kits Manual, reproduced from Appendix E (Modifications) of Depot Maintenance Work Requirement DMWR 1-1520-237-3, published by the US Army Aviation and Missile Command. It sets out the depot-level structural rework standards for three helicopter models built on the same H-60 airframe family: the UH-60A, EH-60A, and UH-60L, identified by NSN 1520-01-035-0266, NSN 1520-01-082-0686, and NSN 1520-01-298-4532.

Chapters Covered

This UH-60A EH-60A UH-60L modification kits manual is built entirely around Appendix E and walks through 24 individually numbered Special Service Instruction (SSI) modification kits, each with its own subject, purpose, applicable model, drawing list, references, weight and balance data, manpower estimate, material information, and step-by-step rework instructions:

Together these 24 sections give a depot-level airframe technician everything needed to plan and execute an H-60 structural modification job from end to end: which drawings govern the work, what parts and top kits are required, how the change affects aircraft weight and balance, how many mechanic man-hours to budget, and the exact fastener-by-fastener disassembly, rework, and reassembly sequence keyed to drawing zones and aircraft station/waterline coordinates.

What This Modification Kits Manual Supports

Every SSI in this UH-60A EH-60A UH-60L Airframe Depot Maintenance Modification Kits Manual follows a consistent structure: Subject and Purpose, Applicable Model, Description, Drawings Required for Modification, References, Weight and Balance Data, Manpower estimate by trade (sheet metal mechanic, helicopter electrician, fuel mechanic), Material Information (top kit and sub-kit part numbers), and detailed lettered/numbered Instructions covering removal, modification, and reinstallation of airframe structure by aircraft station and waterline. Illustrations throughout show exploded modification kit layouts with numbered callouts tied to the instruction steps.

Typical structural areas addressed in this manual include the cockpit door posts and canopy hinge structure, side fuselage and gunner’s window reinforcement, frame stations 379.00 and 485.00, upper cabin plating, buttline 34.50, ESSS doublers, tail rotor drive shaft supports, the lower aft transition section, tail cone shear deck and stringers, the station 605.00 bulkhead, the tail rotor pylon and its aft spar/stabilator attachment fittings, side firewalls, engine cowl assemblies, and the HIRSS infrared suppression system repair kit.

Why This UH-60A EH-60A UH-60L Modification Kits Manual Matters

A depot-level structural modification on a Black Hawk airframe is not a job to approach from memory or generic sheet-metal experience. This manual gives the exact drawing numbers, part numbers, fastener callouts, and station/waterline coordinates that the US Army itself uses to control these repairs, so the correct hardware goes into the correct location and the resulting weight and balance change is properly documented. Working from the actual DMWR text also means warnings and cautions about drilling near existing structure, wiring, and fuel cells are followed exactly as written, rather than improvised.
