One passenger and one crew member were injured in an Air China passenger jet accident here Sunday.

The fore-undercarriage of the Boeing 767 took back automatically before taking-off, which was due 5:15 Sunday afternoon from Beijing to Dubai, General Administration of Civil Aviation (CAAC) officials said.

Most of the passengers have boarded the aircraft when the jet head fell onto the ground, according to the CAAC.

The two passengers, who are both Chinese, have been sent to hospital, and other passengers have been properly settled while a CAAC team has been conducting investigations.

The passenger and the crew member felt dazed, and medical checks show they were only slightly injured, the CAAC said.

All 148 passengers are boarding another Air China aircraft, waiting for taking-off Sunday night, according to the CAAC.
