NATO Supply Class 4920 is a classification within NATO Supply Group 49, which is dedicated to Maintenance And Repair Shop Equipment. Specifically, Class 4920 focuses on Aircraft Maintenance And Repair Shop Specialized Equipment.
This class includes specialized equipment that is used in aircraft maintenance and repair shops. It encompasses a wide range of tools and machinery that are specifically designed for the maintenance and repair of aircraft.
Some examples of equipment that fall under NATO Supply Class 4920 include:
1. Aircraft engine stands: These are used to securely hold aircraft engines during maintenance and repair work.
2. Aircraft jacks: These are hydraulic or mechanical devices used to lift and support aircraft during maintenance procedures.
3. Aircraft tire changers: These are specialized machines used to remove and replace tires on aircraft.
4. Aircraft component test sets: These are electronic testing devices used to diagnose and troubleshoot various components of an aircraft.
5. Aircraft fuel system maintenance equipment: This includes equipment used for cleaning, testing, and repairing aircraft fuel systems.
6. Aircraft hydraulic system maintenance equipment: This includes tools and machinery used for maintaining and repairing hydraulic systems in aircraft.
7. Aircraft electrical system maintenance equipment: This includes equipment used for testing, repairing, and maintaining electrical systems in aircraft.
These are just a few examples of the specialized equipment that falls under NATO Supply Class 4920. The class is designed to ensure that aircraft maintenance and repair shops have access to the necessary tools and machinery to effectively and safely carry out their work.

Includes Maintenance stands designed for support of aircraft assemblies during repair or overhaul; Test Stands and Test Equipment specially designed for maintenance and repair of aircraft components such as: engines, generators, hydraulic systems, armament, automatic pilot, fire control, flight control, and navigational systems.
Excludes Hand Tools; Airfield Maintenance Platforms; Basic types of electrical and electronic test instruments, including those specially designed, such as ammeters, voltmeters ohmmeters, multimeters, and similar instruments, as shown in the indexes to the FSC; Test Apparatus used for both communications and other electrical and electronic equipment.
Note-Specialized equipment which is designed for automotive maintenance and repair, and which is also used for the maintenance and repair of nonautomotive vehicles or equipment, will be classified in Class 4910. Jigs, fixtures, and templates used in conjunction with maintenance and repair shop specialized equipment are classified in this group. However, jigs, fixtures, and templates used in conjunction with metalworking machinery are classified in Group 34. Infrared assemblies, subassemblies, and components specifically designed as test and maintenance specialized equipment are classified in the appropriate classes of this group. Excluded from this group is infrared equipment designed for testing communications and night vision equipment.
