A China Airlines passenger plane bound for Hong Kong was forced to make a U-turn and return to Taipei’s airport after declaring a state of emergency on Saturday night, according to media reports.
According to Taiwanese media reports, flight CI919 departed from Taipei Taoyuan International Airport on Saturday night, issued a “7700” code to indicate an emergency situation, and returned to the airport safely.
According to flight data, the aircraft began its flight at 6:06 p.m. and landed at the airport at 7:35 p.m.

According to aviation tracking websites, the aircraft involved in the incident was an Airbus A330. China’s airline fleet includes 18 of his aircraft from the same manufacturer.
Hong Kong International Airport posted on its website that the flight was delayed as of 9:20 p.m.
The newspaper has contacted China Airlines for comment.

An aircraft engineer who spoke on condition of anonymity said a 7700 code can be issued for a variety of reasons, including technical issues or medical emergencies.
Experts believe that a sudden drop in altitude could be associated with a possible failure of the aircraft’s pressurization system, in which case the pilot would have to descend rapidly to maintain cabin pressure at the appropriate level. He suggested that it would be.
“This means either there is a problem with the aircraft’s pressurization system or there is an opening in the aircraft that allows air to escape,” the engineer said.
“We will only know if there was a technical or structural problem with the plane’s pressurization system after inspection on the ground.”
