## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Propeller/rotor contact to person, standing - starting engine(s)
  - procedures/directives - improper, flight engineer (cause)
  - visual lookout - inadequate, ground personnel (cause)
  - communications - not understood, flight engineer (cause)

## Analysis

DURING ENGINE START NUMBER 4 ENGINE WAS STARTED. THE SIGNAL WAS GIVEN TO THE GROUND CREWMAN TO DISCONNECT THE AIR START UNIT. THE ENGINEER THOUGHT HE HEARD 'START NUMBER 3'. ENGINE NUMBER 4 WAS SHIFTED UP, IT STABILIZED, AND ENGINE NUMBER 3 WAS STARTED. AFTER THE GROUND CREWMAN DISCONNECTED THE AIR START UNIT, HE TURNED AROUND AND WALKED INTO THE PROPELLER OF THE NUMBER 3 ENGINE.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19861009052259A](https://openairdocs.org/incident/19861009052259A), Oct 9, 1986: Lkheed 188ALKHEED, Boston, MA. A ground crewman walked into a propeller. The pilot failed to supervise the engineer who was starting the engine.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
