What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On 3/12/14 at 1720 a swissport ramp employee drove a beltloader from avianca gate to the south african gate. As he approached the right side of the sa aircraft he was instructed to position the beltloader at the aft bulk pit. Driver was being marshalled by another ramp agent. When he came to the final stop about 2 feet from aircraft the marshaller instructed him to raise the belt. While raising the belt the driver said he had his right foot on the brake. After the belt was raised the marshaller instructed the driver to come forward and turn slightly to the right. The driver put his foot on the gas pedal and the beltloader accelerated towards and under the aircraft. The marshaller jumped out of the way and was not injured. The driver stopped the beltloader after it had gone under the aircraft and struck the under portion of the fuselage causing minor damage.
Note: at some point during this operation the beltloader operator put the gear shift in neutral. When the driver put the beltloader back into gear he started moving forward and actually hit the accelerator instead of the brake.
