US military orders new safety guidelines for key Osprey part after near-crash

The military has ordered new safety guidelines for a key part in all Osprey aircraft after a recent accident revealed the same problem that caused a fatal crash in Japan last year. During a Nov. 20 flight involving a CV-22B Osprey in New Mexico, the crew received warnings that the metal gears inside the aircraft's transmission, known as the proprotor gearbox, were in trouble.
