BoCom Leasing, the financial leasing arm of China's Bank of Communications, signed a deal with Commercial Aircraft Corp. of China, Ltd. (COMAC) on November 23 to buy 30 of the nation's homegrown C919 large passenger planes.

BoCom Leasing signed the new deal as it tries to expand its fleet size to cash in on the country's rapidly growing demand for air services.

The deal is also a boost for COMAC as the newcomer looks to compete with dominant passenger plane makers Airbus and Boeing to win a slice of the international aviation market share. Neither side revealed the value of the order.

The new deal brings the total order of C919 passenger jets to 195. COMAC said that test flights for the single-aisle C919 are scheduled for 2014, and delivery is slated for 2016.
