Another Marine Corps aircraft has made an unplanned landing in Japan, the third such incident in less than a week.

An MV-22B Osprey with Marine Medium Tiltrotor Squadron 265 made a "precautionary landing" Saturday at Amami Airport in Japan after the pilots received a cockpit warning indication, according to the 31st Marine Expeditionary Unit.

No one was injured, and the Osprey left the airport on Sunday after maintainers made sure it was operating normally, the 31st MEU said in a statement.


This latest incident comes after another MV-22B Osprey and an F/A-18 had to make separate unplanned landings on June 6. No injuries or property damage were reported in connection with either of those two landings. 

The Osprey from Marine Corps Air Station Futenma landed at U.S. training facilities at Ie Shima off the coast of Okinawa, and the Hornet landed at the at Matsushima Airfield, a Japanese Air Self-Defense Force facility on the mainland.


Despite the back-to-back incidents, flight operations for MV-22B Ospreys are not being paused, said Capt. George McArthur, a spokesman for the 31st MEU.

Meanwhile, Marine Corps officials have not publicly released the results of investigations into the Dec. 7 crash that killed Capt. Jake Frederick, who was assigned to the 1st Marine Aircraft Wing when his F/A-18C went down about 120 miles southeast of Iwakuni, Japan; or the Dec. 13 crash of an MV-22B Osprey Marine Medium Tiltrotor Squadron 265, which went down in shallow waters off Okinawa after its rotor struck a refueling line.

Separately, an MV-22B Osprey from Marine Medium Tiltrotor Squadron 262 had to make an emergency landing at Futenma on Dec. 13, 2016, when its landing gear failed, and an AH-1Z Viper helicopter with Marine Light Attack Helicopter Squadron 267 made an unplanned landing on Ikei Island on Jan. 20.
