SECTION I. INTRODUCTION

1-1. Purpose. This Technical Bulletin (TB) implements the provisions of AR 750-1 (Army Materiel Maintenance

Policies) and AR 750-2 (Army Materiel Maintenance Wholesale Operations). Maintenance Expenditure Limits (MELs)

have been established to ensure that only the repairs that benefit the Army are done. This TB is intended to be used for

end items in Federal Supply Class (FSC) 1510 (Fixed Wing Aircraft), and FSC 1520 (Rotary Wing Aircraft). It establishes

maximum direct labor man-hour repair allowances for Aviation Unit Maintenance (AVUM) and Aviation Intermediate

Maintenance (AVIM) level organizations, and maximum dollar cost expenditures for depot level activities. This TB

includes instructions for conducting damage assessment evaluations. Provides guidance for requesting disposition

instructions or waiver authorization from AMCOM, when the damage and/or deterioration to an aircraft and on board

mission related equipment, exceeds the maximum repair allowances, or needed repairs exceed the authorization

prescribed in applicable -23 manual's Maintenance Allocation Chart (MAC).

1-2. Scope. This TB applies to the Active Army, Army National Guard (ARNG), U.S. Army Reserve (USAR),

Department of Defense (DOD) and other Government or contract activities that operate, store, or maintain Army aircraft.
