Some years ago I was mapping the techlog process with a household-name flag carrier. The techlog confirms an aircraft's technical status before it flies, and at every airline the copies go to the same few places.
This airline had an extra copy. “We send it to George,” the room told me. George worked in another city, so we got him on the phone. “I have no idea why I get them,” he said. “I get hundreds every day, so I store them in Warehouse 5.” Had anyone ever asked to see one? “Never. Not once.”
The copy was a leftover from a merger years earlier. That one conversation saved the airline around $600,000 a year. Nobody had done anything wrong. The problem lived in the handover between departments, the one place nobody owned.
