UH-60 BLACK HAWK MAINTENANCE
The UH-60L helicopter uses a preventative maintenance structure that is based on number of flight hours and calendar days inspections. The military design of the Black Hawk allows a long time period (40 flight hours) before a mechanic is required to perform any inspections. The major depot level maintenance is referred to as the Phase Maintenance Inspection (PMI) which consists of different phases and is divided into several parts. Military Aviation Authorities (MAA) may require the operator to adjust the maintenance structure as per their additional requirements. The table below showcases the notional maintenance schedule, that is recommended by the Original Equipment Manufacturer (OEM) Ace Aeronautics, LLC:
