Casualties unknown • Washington, DC, US

An investigation into an accident involving a propeller-driven aircraft determined that a ramp agent's judgment was potentially impaired by medication and heat.

What happened

During the conclusion of his shift, a ramp agent was involved in an accident near a propeller-driven airplane. The incident occurred on a day characterized by extreme heat. While the specific mechanics of the contact were not detailed, the investigation focused on the actions of the ground personnel during this period.

Findings

Investigators determined that the ramp agent possessed the necessary training and experience required to work in the vicinity of propeller-driven aircraft. Statements from coworkers supported the conclusion that the agent was a hard worker and typically safety conscious, suggesting that the carelessness observed during the accident was inadvertent and uncharacteristic of his usual performance.

Specific factors identified during the investigation included:

  • The ramp agent was at the end of his work shift.
  • Ambient temperatures were very high on the day of the accident.
