Took them by surprise my ass. There needs to be some Squadron Commanders, Maintenance officers, and Maintenance Chiefs looking for a new line of work. Corrosion has always been an issue in the Navy and Marine Corps. This problem didn’t just suddenly appear out of thin air.
I know this particular issue. The corrosion is inside voids only opened at depot level. Probably never intended to be opened during lifespan of aircraft. The way the plane is constructed prevents the corrosion in those from being accessed the way it needs to be.
