Poor communication was blamed for the crash of a commuter plane, killing all 14 aboard, because a stabilizer came off in flight. A maintenance crew had started removing both leading edges of the plane the night prior to the accident. When their task had not been completed at the time of the shift change, the shift change document was written up as "Removed top edge screws". Two mechanics coming on duty read the message, unaware that the left side screws had also been removed. Had the write-up said, "Removed top edge screws on stabilizer left and right leading edge", people might still be alive. Specific language is needed, especially when communicating technical information.
