INTERNATIONAL: A Taiwanese Mirage 2000 fighter jet has crashed into the sea off the island's southeast coast on Monday after mechanical issues but the pilot was rescued, the air force has said, the second combat aircraft loss in the space of three months.

The air force have said the French-built aircraft took off just after 10 a.m. on a training mission from the Chihhang air base in Taitung and reported it had to return after a mechanical problem.

The pilot has ejected over the sea south of the air base and was rescued safe and in good condition by helicopter, it has added.

An investigation team has been set up and sent to Taitung, the air force has also said.

Taiwan has received its first Mirage jets in 1997, though they have been upgraded several times since then.

In January, the air force suspended combat training for its F-16 fleet after a recently upgraded model of the fighter jet crashed into the sea, killing the pilot.

Last year, two F-5E fighters, which first entered service in Taiwan in the 1970s, have crashed into the sea after they apparently collided in mid-air during a training mission, also from the Chihhang air base.

In late 2020, an F-16 has vanished shortly after taking off from the Hualien air base on Taiwan's east coast on a routine training mission.

While Taiwan's air force is well trained, it has been repeatedly scrambling to see off Chinese military aircraft intruding in its air defense zone in the past two years, though the accidents have not been linked in any way to these intercept activities.

China, which claims the island as its own, has been routinely sending aircraft into Taiwan's air defense zone, mostly in an area around the Taiwan-controlled Pratas Islands but sometimes also into the airspace between Taiwan and the Philippines.
