Power bank fire on China Eastern flight MU2421 in Guiyang

A passenger power bank ignited in an overhead bin on China Eastern Airlines Flight MU2421, an Airbus A320, after the aircraft landed at Guiyang Longdongbao International Airport on 24 July 2026. Cabin crew quickly extinguished the flames, airport firefighters responded, and no passengers or crew were injured. The aircraft suffered only minor smoke damage.

China’s aviation authority tightened power‑bank rules in June 2025, requiring China Compulsory Certification (3C) markings and prohibiting placement of power banks in overhead compartments. The incident follows similar lithium‑battery fires on other Asian carriers in recent months, prompting renewed scrutiny of portable battery safety on commercial flights.
