In an interview with The Associated Press, Conley said he believed it was the pilot's instinct to complete the military exercise that drove his decisions. A second vibration followed. This time one of the five pinion gears inside the left proprotor gearbox was vibrating. When the third chip burn warning posted, the crew was close to mainland Japan and just 10 miles from its nearest airfield. The official guidance after three chip burns was to "land as soon as practical," guidance that still leaves that decision to the pilot's discretion.
The fourth and fifth chip burn warnings came fast. Then with the sixth, escalation: just chips. It meant the Osprey could not burn them off. "Land as soon as practical" turned into "land as soon as possible." Still, the crew members did not act with urgency. Investigators later found the fail message occurred because the detector "had so many chips on it, it couldn't keep up," Conley said.
