The Shanghai-listed company plans to fund the purchase in part through a private placement of shares to raise 4.5 billion yuan, according to a statement to the exchange yesterday.
The single-aisle A320 has a list price of $97 million, according to Airbus.
"Demand in China's domestic and international aviation market is steadily increasing," Spring said in the statement. "The company intends to reasonably expand the scale of its fleet to increase its air transport capacity."
Spring's shares, which had been suspended since June 26 amid a rout on China's stock market, were down the daily limit of 10 per cent to 113.48 yuan after resuming trading today.
The company's net profit for the first quarter this year jumped 46.43 per cent year-on-year to 254.32 million yuan.
China, the world's second-largest economy, is already Asia's biggest aircraft buyer as a growing middle class takes to the skies in ever-increasing numbers.
But China hopes part of its vast aircraft market will go to a homegrown passenger plane -- the 168-seat C919 -- in a challenge to the global dominance of Boeing and Airbus.
Chinese economic growth is also slowing and expected to soften further in coming years -- a trend industry officials say could put a dent in air travel.
China's gross domestic product expanded 7.4 per cent last year, the slowest since 1990. The country's GDP grew 7.0 per cent year-on-year in the second quarter, matching the 7.0 per cent expansion in the first three months of this year.
