An investigation by the US Department of Defense's Office of the Inspector General (OIG) has concluded that the commander of the US Marine Corps' first Bell Boeing MV-22 Osprey squadron falsified maintenance records, but that this played no part in two fatal Osprey crashes.

The OIG ruled that a small number of the commander's subordinates knew of the falsification, but took no action.

The OIG concludes that the commander began falsifying the records in December because of perceived pressure from superior officers. But the OIG found no evidence that any officer senior to the squadron commander directed the action.
