Next the turnover should identify or describe the aircraft safety state, i.e.; prohibitions to system activation, pinch or crush hazards present, and lock out/tag out activity. Management and mechanics should pass on safety information during crew shift briefings. These briefings must occur prior to moving to the aircraft or starting work.
Work cards or other maintenance paperwork contain important safety information that should be referenced in the turnover log. Work cards are often reposted to the planning booth between shifts where important information may be missed. That is why it should also be described in a turnover log. Other maintenance work in progress is recorded on continuation sheets or on aircraft logbooks depending on the circumstances.
Heavy maintenance checks on large aircraft can involve hundreds or thousands of work cards and their progress is often recorded either on work cards or attached nonroutine forms. If this sounds like a lot of work; it is. However, constant use and enforcement will make the use of the turnover process routine once it becomes part of the work culture.
If one were to review the maintenance-related accidents on record the lack of good RII management has played a role. Emphasis on required inspections and safety conditions must be trained into the work force and enforced by the supervision. Constant review by the quality unit, with verification on the aircraft, drive RII compliance as well as assure that communication processes provide the accuracy needed to make shift and work turnover a successful safety tool.
