The Marine Corps deputy commandant for aviation told Aerospace Daily that the MV-22 Osprey is facing reliability issues due to inaccurate predictive modeling. Lt. Gen. George Trautman said reliability and maintainability are “not meeting my full expectations yet.” He said it's become evident that early predictions of mean time between failures on certain parts were inaccurate. But he praised Bell Boeing for being engaged in working on the issues.
