Narrative:Following a maintenance inspection, the inspections and tool control performed by the maintenance shift was not according to procedures and failed to identify a breaker bar with an attached socket on the main rotor (MR) head of the helicopter.
During the start-up sequence of engine no. 2, the breaker bar and the socket ejected from the MR head, and the breaker bar penetrated the leading edge of a moving rotor blade, while the socket ended up on the apron.
Consequential human factor effects – partly caused by an ongoing discussion with the management regarding future work shifts, organisational structure and maintenance procedures perceived by engineers as being less than optimum – might have influenced the decision-making and the effectiveness of the applied procedures of the shift.
