NAVAIR Issues V-22 Bulletin and Interim Flight Clearance

Based on engineering analysis, on December 20, 2024 NAVAIR issued a fleet bulletin directing the inspection of V-22 Osprey to verify the flight hours on each Proprotor Gearbox (PRGB) prior to an aircraft’s next flight.

Aircraft with PRGBs that currently meets or exceeds a predetermined flight-hour threshold will resume flights in accordance with controls instituted in the March 2024 interim flight clearance (IFC).

V-22 Joint Program Office Welcomes New Leader

Colonel Robert Hurst relieved Colonel Brian Taylor as the commanding officer of the V-22 Joint Program Office (PMA-275) during a change of command ceremony at the Air Test and Evaluation Squadron Two One’s (HX-21) hangar on Naval Air Station Patuxent River, Oct. 10.

V-22 Joint Program Issues Bulletin to Restrict Flights

Based on the recommendation from the V-22 Joint Program Office, the U.S. Marine Corps, U.S. Air Force Special Operations Command and U.S. Navy issued a time limit, via fleet bulletin, on the V-22 Input Quill Assembly, effective Feb. 3, 2023.

The imposed time limit will restrict flight on a subset of V-22s until the Input Quill Assembly is replaced. The Input Quill Assembly is an element of the proprotor gearbox, which houses the aircraft clutch.

This recommendation is based on a progressive increase in Hard Clutch Engagement events and ongoing engineering analysis.

Flying into 40: V-22 program office recognizes four decades of collaboration

Forty years ago this month, the Department of Navy (DoN) took control of what is now known as the V-22 Joint Program Office (PMA-275), responsible for the cradle-to-grave acquisition, sustainment, development and production of the venerable tiltrotor aircraft.

With more than 700,000 flight hours under its articulating halos, the V-22 Osprey is a military marvel, providing unmatched capabilities to the U.S. Marines, Navy, Air Force and the Japan Ground Self-Defense Force.
