The vertical/short takeoff and landing (VSTOL) MV-22 Osprey underwent its maiden deployment in 2006 and serves as a multi-mission aircraft often supporting combat and logistical operations.
In Marine Corps use, the MV-22 will replace the CH-53D Sea Stallion transport helicopter. In Navy use, the aircraft is potentially a replacement for the C-2 Greyhound.
With its massive three-bladed 38-foot propellers, the Osprey is not only unusual in appearance, but also in composition. Its fuselage and empennage are partly comprised of aluminum and carbon/epoxy composite. The wing and nacelles are comprised of carbon/epoxy composite and fiberglass.
A relative new comer, the first MV-22 induction to the command was in 2015 at FRCSW Site Miramar when FRCSW joined FRC East in establishing the Navy’s Integrated Maintenance Program (IMP) requirements for the tilt-rotor aircraft.
The IMP model is also applicable to the Air Force’s Osprey fleet.
The IMP targets the structural integrity of the airframe and is comprised of Planned Maintenance Interval-One (PMI-1) and PMI-2.
During induction, the aircraft’s engines, fuel cells, and select panels are removed and preserved. Specifications for both PMI processes are similar, however, PMI-2 is a more in-depth event that includes painting of the aircraft.
FRCSW completed its first PMI-1 in May 2016 at its Miramar site and inducted its first MV-22 for PMI-2 in January 2019 at its North Island site.
