Reassembly complete...Now what about these extra parts?

On November 9, 2013, about 1245 central standard time, a Eurocopter Deutschland GMBH EC135P1 helicopter, N911KB, impacted terrain near Shreveport, Louisiana. The commercial pilot and two company mechanics sustained minor injuries and the helicopter was substantially damaged.

A review of the helicopter's log book found an entry dated October 31, 2013, that a mechanic performed the action "disassemble, inspect, and reassemble tail rotor pedals". According to a statement provided by the company's director of maintenance, after the accident a search of the area maintenance area was conducted. Near the area where the helicopter was previously repaired, a small parts bag was found tied to the tail rotor control cable that had been replaced. Inside of the bag were bolts similar to the bolts used to secure the anti-torque pedals.

Complacency can bite any of us on any given day. Consider your strategy to break error chains. "second set of eyeballs," CYA checks, tool and parts inventory post-maintenance... Are there chinks in your armor?
