To improve its H-60 MRO capacity, FRCSW opened Building 325 in 2016, an 110,627 square-foot facility solely devoted to the maintenance and repair of the Sea Hawk.
The command’s H-60 MRO program applies the Integrated Maintenance Program (IMP) to assess and ensure the structural integrity of the MH-R and MH-S models of the airframe. Both models support aircraft carrier battle groups. Under the IMP, aircraft undergo a Planned Maintenance Interval-One or Two (PMI-1 or PMI-2) cycle.
PMI is a cell-based structure, with each cell dedicated to a specific function that includes induction, disassembly, evaluation, repair, modification, assembly, test and finally a “sell” or return to the fleet.
The inspection targets six sections or zones of the aircraft. Not all zones are covered during both PMI cycles. During PMI-1 the cockpit, cargo area, fuel system, tail pylon and tail rotor are examined. In PMI-2, artisans revisit the cockpit and cargo area, and assess the tail cone and the upper deck of the aircraft and main rotor.
The aircraft is also stripped and painted.
Although out of the scope of the IMP, FRCSW handles in-service repair (ISR) work on major components under a separate work order. Modifications and upgrades, like avionics, are also sizable portions of workload
Six years ago, the command purchased a Laser Alignment Fixture to assist in the repair of crash damaged H-60 aircraft.
The only one of its kind in the Navy today, the system is applicable to all H-60 variants and enables the alignment of the aircrafts beams, drive shaft and engine mount.
Use of the fixture expanded in FY 2018 when Fleet Support Team engineers applied it during a study to establish baseline data to extend the life of the airframe.
