TAIPEI (Taiwan News) — A foreign man who jumped onto the landing gear of a departing China Airlines (CAL) flight last November was charged Friday (Feb. 28) with violating immigration laws.

On Nov. 2, the man appeared on the tarmac at Taiwan Taoyuan International Airport and tried to enter CAL flight 28 by climbing up over the wheels, CNA reported. The pilot of a South Korean Asiana Airlines plane taxiing behind spotted and told the authorities, who arrested him before he managed to disappear inside the plane.

In the two backpacks the man was carrying, investigators found a diary with notes in Russian, but he has given no verbal explanation of his motives. After a Orthodox priest reportedly visited him, he wrote that he had wanted to fly to the Pacific island of Palau, which was the flight’s destination.

Prosecutors said Friday that the man had never responded to questions about how he successfully entered a part of the airport off-limits to the public.

The Taoyuan District Court will conduct the trial, CNA reported. The man faces a maximum prison sentence of three years or a maximum fine of NT$90,000 (US$2,960) for violating immigration rules.
