A small propeller aircraft crashed into Beijing's tallest building on Tuesday evening, causing debris to fall onto the streets below in the city’s central business district. The incident occurred at the 528-meter Citic Tower, commonly known as "China Zun," which houses the headquarters of the state-owned Citic financial services group.

Video footage circulating on Chinese social media showed parts of the light aircraft near the upper section of the skyscraper, along with visible damage to windows on a high floor. Emergency services, including multiple fire engines and police vehicles, quickly arrived at the scene. Authorities cordoned off the surrounding block and restricted access, also preventing bystanders from photographing the building. Despite the incident, Chinese state media did not report on the crash on Tuesday evening, and related content was heavily censored on social media platforms. Beijing’s foreign ministry had not responded to requests for comment as of late Tuesday.

Eyewitnesses in the vicinity described seeing fragments fall from the tower near 6 p.m. local time. One bystander riding a bicycle reported that a delivery rider nearby mentioned an explosion and pointed out broken windows on one of the upper floors.

The Citic Tower is located in a highly secure area only a few kilometers from Zhongnanhai, the Chinese Communist Party’s leadership compound. The city enforces some of the world’s strictest airspace regulations, with specific bans on drones and private light aircraft over urban areas requiring prior authorizations. According to a former pilot familiar with the city’s airspace restrictions, which include a no-fly zone within the capital’s second ring road, unauthorized flights in this area typically trigger immediate warnings and possible responses from the Chinese air force. The Citic Tower stands just outside the more expansive third ring road.

The aircraft involved was identified by tracking service Flightradar24 as a Sunward SA60L Aurora, a two-seat, single-engine sport aircraft bearing registration number B-12PP. Images released show what appears to be the name of a flying school based in eastern Beijing on the side of the plane. The manufacturer, Stairair Aircraft from Hunan Province, describes the SA60L as having a maximum takeoff weight of 600 kilograms and capable of cruising at speeds up to 220 km/h.

No official details have been released regarding casualties or the cause of the crash. Authorities have maintained a tight control over information and access to the site as investigations continue. The incident has drawn attention for its rare breach of Beijing’s heavily regulated airspace and the symbolic prominence of the building involved.
