A China Southern Airlines Airbus A321 was struck by lightning while taxiing at Shenzhen Baoan International Airport on Saturday afternoon [1].
The incident highlights the risks posed by severe weather to aircraft on the ground, where lightning can cause structural damage or electronic failure.
Flight CZ3209 was bound for Wuxi in Jiangsu province when a heavy thunderstorm produced the strikes [1]. The crew was forced to abandon the departure and return the aircraft to the gate for an immediate safety inspection [1].
Inspectors later identified 20 lightning-strike marks on the aircraft [1]. The plane remained grounded while technicians evaluated the extent of the damage to ensure the vessel was airworthy.
The disruption caused a delay of approximately four hours for the passengers on board [2].
Modern aircraft are designed to conduct electricity around the fuselage to protect passengers and crew, a process known as the Faraday cage effect. However, multiple strikes during a single event can lead to localized punctures or damage to sensitive sensors.
Airport authorities and airline officials managed the return to the gate to prevent further risk during the storm [1]. The aircraft was removed from service pending the completion of the technical review [1].
“20 lightning-strike marks were found on the aircraft.”
While commercial aircraft are engineered to withstand lightning strikes through specialized shielding and grounding, the discovery of 20 distinct marks on a single airframe suggests an unusually intense electrical event. This incident underscores the necessity of rigorous post-strike inspections, as lightning can cause invisible internal damage to avionics or compromise the structural integrity of the fuselage skin.
