CCTV footage of the bizarre incident on Tuesday shows the 31-year-old man tossing the coins from the jet bridge as he was boarding the flight with his family at Wuhan Tianhe International Airport in Hubei province.
As a result of the man's superstitious actions, Hainan Airlines flight 7783 departing for Urumqi, Xinjiang was delayed for 40 minutes, affecting 101 passengers on the plane, Chinese media reported.
The video shows the man's wife walking behind him, holding their four-month-old daughter.
As he approaches the cabin door, the man slows down and reaches into his pocket before dropping the coins through the narrow gap between the jet bridge and the plane.
Two 1 yuan and one 1 jiao coins were found on the ground near the aircraft's engine after a security guard alerted airline staff, according to Changjiang Daily.
The man, surnamed Xia, later told police that his mother-in-law insisted that he threw coins at the aircraft to pray for a safe flight since it was the baby's first time flying.
Xia was detained for endangering passenger safety for 10 days in Wuhan, while his wife continued to Urumqi with their daughter.
The engine of an aircraft would be severely damaged or even destroyed if a coin is sucked into it, according to a professor at Civil Aviation University of China cited by China Daily in a previous report.
'The engine could tremble, lose speed and even stop in mid-air if a coin were sucked into its core,' he said. 'That would put all the passengers on board at great risk.'
This is not the first time a passenger has attempted to toss coins into an aircraft engine for good fortune and a safe flight.
Last month, two women in their mid-20s were removed from a Lucky Air flight after they each admitted to tossing a 1 yuan coin as they were boarding a plane at Jinan Yaoqiang International Airport in Shandong province.
In February, a 28-year-old man was detained for seven days after he admitted to throwing two 1 yuan coins at another Lucky Air passenger jet in Anqing, Anhui province, causing the flight to be cancelled.
A similar incident happened in February when a 28-year-old man was detained for throwing two 1 yuan coins at another Lucky Air passenger jet in Anqing, Anhui province
A total of 162 passengers were affected and the incident caused the airline nearly 140,000 yuan (£16,000).
In June 2017, an 80-year-old woman threw her change at a China Southern Airlines flight at Shanghai Pudong Airport to pray for a safe flight, causing a five-hour delay and one million yuan in damages. She was not charged due to her age.
Several months later in the same year, a 76-year-old woman flung several coins into the engine of a Lucky Air flight, also Kunming-bound from Anqing. She was detained but not charged.
