What happened
The incident occurred while the airplane was stationary at a gate, actively engaged in the process of boarding passengers. A catering truck approached the aircraft and collided with its right side. The impact resulted in specific structural damage to the fuselage, including a puncture measuring six inches by fourteen inches, along with several minor dents. Additionally, two formers and one stringer sustained damage during the collision.
The driver of the catering truck later reported that he was approaching the airplane when he received a radio call. While engaged in conversation over the radio, he inadvertently stepped on the accelerator pedal. This action caused the truck to move forward unexpectedly, leading to the strike against the parked aircraft.
The investigation
Investigation into the mechanical aspects of the event focused on the nature of the damage and the operational context. The fuselage sustained a distinct puncture and denting consistent with contact from a ground vehicle. Structural components identified as formers and stringers were also compromised. No mechanical failure of the aircraft itself was cited; the damage was entirely external and caused by the ground support equipment.
Findings
The primary factor contributing to this incident was human error on the part of the ground crew. The driver's attention was divided by a radio communication at a critical moment. This distraction led to the loss of vehicle control, specifically the unintended application of throttle power. The ground vehicle operator failed to maintain proper awareness of the aircraft's position relative to the truck's path.
Safety message
This event highlights the importance of maintaining undivided attention during ground operations near active aircraft. Ground crew members must ensure that communications do not compromise vehicle control, particularly when operating in close proximity to parked planes. Strict adherence to safety protocols regarding radio use while driving support equipment is essential to prevent similar collisions.
