Baggage Handler Struck by Propeller During Maintenance on Night Departure (N422MQ)

Electrical Fault and Maintenance

During a night departure, the crew received an electrical fault indication after starting the left engine. They shut down the left engine to allow a maintenance mechanic to board for troubleshooting. The mechanic identified a failed part and obtained its replacement. The fault had extinguished the airplane's external lights and prevented the acceptance of external electrical power.

Baggage Handler Incident

A baggage handler from another airline arrived behind the airplane with bags for the flight. The crew prepared to shut down the right engine to replace the part and signaled the marshaller to apply external power to maintain cabin lighting. The marshaller was at the external power receptacle on the front right fuselage when the baggage handler walked forward along the right side and into the turning propeller.

Handler Background

The baggage handler was on her second day in that capacity and was working the night shift. She had previously been an aircraft cleaner on the day shift for an operator whose fleet consists entirely of jets. The job change to baggage handler involved no classroom or practical training.
