SEOUL, Dec 30 (Reuters) - South Korea's acting President

Choi Sang-mok on Monday ordered an emergency safety inspection

of the country's entire airline operation system once the

recovery work on the Jeju Air crash is finished.

South Korea's deadliest air accident ever killed 179 people

on Sunday, when an airliner belly-landed and skidded off the end

of the runway, erupting in a fireball as it slammed into a wall

at Muan International Airport.

The top priority for now is identifying the victims,

supporting their families and treating the two survivors for

which no available resources should be spared, Choi told a

disaster management meeting in Seoul.

"Even before the final results are out, we ask that

officials transparently disclose the accident investigation

process and promptly inform the bereaved families," he said.

"As soon as the accident recovery is conducted, the

Transport Ministry is requested to conduct an emergency safety

inspection of the entire aircraft operation system to prevent

recurrence of aircraft accidents," he said.

Jeju Air flight 7C2216, arriving from the Thai

capital Bangkok with 175 passengers and six crew on board, was

trying to land shortly after 9 a.m. (0000 GMT) on Sunday at the

airport in the south of the country.

Two crew members survived and were being treated for

injuries.

Investigators are examining bird strikes and weather

conditions as possible factors in the crash, fire officials have

said. Experts say many questions remain, including why the plane

was going so fast and why its landing gear was not down when it

skidded down the runway and into a wall.
