  2. 2. Federal AviationAdministration2Aircraft Maintenance RecordsIntroductionThis course provides a review of aircraftmaintenance documentation requirements,emphasizing the importance of accurate andcomplete documentation.It identifies common documentation problemsthat can lead to maintenance errors.
  3. 3. Federal AviationAdministration3Aircraft Maintenance RecordsAircraft Maintenance RecordsThe basic requirements for Aircraft MaintenanceRecords are the same.The method of meeting those requirements may bedifferent depending on the type of operation.
  4. 4. Federal AviationAdministration4Aircraft Maintenance RecordsCommon problems• No documentation.• Inadequate description of work performed.• Using the wrong references.• Poor shift turnovers

  8. 8. Federal AviationAdministration8Aircraft Maintenance RecordsNTSB FindingDepartures from approved procedures included failuresto give proper shift / turnover reports, failures to usemaintenance work cards as approved, failures tocomplete required maintenance/inspection shift /turnover forms, and a breach in integrity of the qualitycontrol system.
  9. 9. Federal AviationAdministration9Aircraft Maintenance RecordsShift /TurnoverThe transfer of critical information between work groups orshiftsIt needs to be as detailed as necessary, depending on thetasks involvedSharing of information by the people doing the task
  10. 10. Federal AviationAdministration10Aircraft Maintenance RecordsWhy is Shift/Task Turnover ImportantData shows that poor shift/task turnover is a contributingfactor to accidents/incidents.Challenges related to shift turnover include:1. A high demand for teamwork and communication skills2. Lack of structured and standardized policies andprocedures3. Using a location that is not conducive for discussion andplanning
  11. 11. Federal AviationAdministration11Aircraft Maintenance RecordsWhy is Shift/Task Turnover Important4. Finishing workers are tired and want to depart the facility.5. Lack of adequate shift overlap to provide time to give one-on-one briefings between the teams.6. Absence of a process to ensure departing personnel havedocumented all tasks accomplished or started.7. Minimal training on procedures for shift/task turnover.High-quality shift/task turnover procedures enableimprovement in safety and accountability to allinvolved in the work.
  12. 12. Federal AviationAdministration12Aircraft Maintenance RecordsImplement a Shift/Task Turnover process• Formalize policy and procedures that make theturnover as important as the work.• Communicate policy and procedures to all personnel.• Deliver initial and recurrent training on how to conduct agood shift/task turnover.• Provide a time and place for formal shift/task turnover.• Consider technology enhancements that improve thetransfer of visual information (e.g., photos, graphics).

  21. 21. Federal AviationAdministration21Aircraft Maintenance RecordsI’ve always done it this way!This is an example of what happens when we do not pay attention to detail, and do not followinstructions and checklists!A KC-135 Aircraft was being pressurized at ground level. The outflow valves which are usedto regulate the pressure of the aircraft were capped off during a 5 year overhaul and neveropened back up. The post-investigation revealed: that a civilian depot technician who, "hadalways done it that way," was using a homemade gauge, and no procedure.The technicians gauge didnt even have a max "peg" for the needle and so it was no surprise hemissed it when the needle went around the gauge the first time. As the technician continued topressurize the aircraft, and as the needle was on its second trip around the gauge the aircraftwent "boom" - the rear hatch was blown over 70 yards away, behind a blast fence!An incident like this is never funny and is further regrettable when we consider that thismistake is one that we (the taxpayers) will end up paying for. Fortunately, no one was reportedas being injured.This was a good "Lessons Learned" for making sure we have trained people, who have the righttools, and who are following detailed procedures. And it should serve as a reminder that justbecause you’ve always done it that way, it does not make it the “right” way!
