Those injured were receiving medical treatment and authorities were investigating the incident, Chaoyang district government said in a statement on Saturday.
"A single-engine, two-seat light sport aircraft collided with a high-rise building while flying near the East third ring road in Chaoyang, at 5.55pm on June 26," said the statement, which was posted on social media.
"There was only one person on board, the pilot, who died," the statement added, without giving any further details of the possible cause of the crash.
Damage to the facade of the skyscraper appeared to be limited to a hole caused by the loss of two large glass panels.
The gap had been temporarily boarded up as of Saturday.
Reuters reported on Friday the crash into the 528-metre-high building, known as CITIC Tower or China Zun, in central Beijing.
It is about 6km from the Forbidden City visited by thousands of tourists each day.
It is also near Zhongnanhai, a compound that houses the offices of China's top political leadership.
The incident follows Beijing's ban since May on buying, renting or flying drones without authorisation, due to public security concerns.
The last aircraft crash in Beijing was in 2022, when a tourist helicopter crashed during a flight between the Changping and Fangshan districts, killing the two pilots on board.
