The resumption came days after a team of civilian, government and military experts cited defects in the rotor mast of the Marine helicopter as the cause of the crash.

The MUH-1 Marineon, the Marine variant of the KUH-1 Surion helicopter, crashed at a military airport in the southeastern city of Pohang on July 17, killing five of the six Marines aboard and injuring the other.

Before the resumption, the Army conducted the detailed inspection of the chopper's rotor mast and conducted test flights to ensure it has no operational problems.

"At 9 a.m., the Army resumed the normal operation of the Surion choppers that have gone through the inspection and flight tests," the Army said in a text message sent to reporters.

Currently, 30 percent of some 90 Surion choppers have undergone the inspection. "We plan to resume the operation of the remaining choppers after the inspection," the Army said.
