Frontier A320 engine damaged by air conditioning tube at Charlotte: pictures

A Frontier Airlines Airbus A320 sustained damage to its left-hand engine after a ground-based air conditioning tube was ingested as the aircraft prepared for departure. The unfortunate incident, which took place at Charlotte-Douglas International Airport (CLT) in North Carolina, led to a delay of around nine hours for the passengers affected while the airline sourced a replacement aircraft.

The aircraft concerned, a 5.7-year-old Airbus A320 registered as N365FR, was at its parking stand preparing for departure to New York-LaGuardia Airport (LGA) on August 16, 2025, as Frontier Airlines flight 3134, a flight that was due to take around one hour and twenty minutes to complete. According to the website PYOK, flight 3134 had already boarded passengers when eyewitnesses caught the moment that the ground air supply hose was sucked into the engine.

During the warmer summer months, ground power air conditioning units are an essential piece of ground equipment that supplies cooled air into the aircraft cabin while the engines are switched off and the aircraft is not running its own air conditioning systems.

The cooled air is supplied from large hoses that connect to a special port in the underbelly of the aircraft. When these tubes are not in use, they are supposed to be securely stowed either at the base of the airbridge at the parking stand or in a dedicated storage box located close to the aircraft itself.

It became clear that the engine would have to undergo further inspection, so the airline managed to source another aircraft in the form of Airbus A321neo N715FR to operate the service instead. While the original flight had been scheduled to depart at 09:55 local time, the passengers eventually escaped Charlotte at 19:06, according to data from Flightradar24.

Videos shared by passengers and reported by PYOK captured the hose disintegrating as it spun within the engine’s outer fan blades, with one passenger remarking, “That engine’s fried.” Eyewitness accounts and footage highlighted the severity of the event, showing the shredded hose entangled in the engine fan, with the remnants strewn across the airport tarmac. Airport personnel responded to the aircraft quickly, securing the aircraft and ensuring that there were no injuries occurred among any of the passengers or crew prior to disembarking the aircraft itself.

The airline is reportedly conducting a thorough investigation to determine the cause of the incident and to establish what lessons can be learned to prevent similar occurrences from happening in the future. Investigators will be particularly keen to establish if any lapses in operating procedures, ground equipment handling, or an engine malfunction may have contributed to the incident.

As at the time of writing, the damaged A320 remains out of service at Charlotte Airport as airline engineers assess the condition of the engine and whether it will need to be removed from the wing for a more detailed inspection.
