Activities that operate NALCOMIS should store the current month and the two preceding months of flight data on the host computer in historical data format. For example, if the current month is March, January and February data should be retained and December database should be transferred to storage. This  electronic  database  must  be  stored  for  one complete inspection cycle or 12 months, whichever is longer. Upon transfer of the aircraft, ensure that the aircraft inspection  files,  TD  compliance  files,  aircraft  general files,  and  electronic  history  data  tape  files  are forwarded with the aircraft. In addition, activities should  produce  an  Aircraft  Transfer  Report  and forward  it  along  with  the  other  aircraft  logbook records. The  NALCOMIS  OMA  database  will automatically  retain  6  months  of  historical  data. Activities that operate NALCOMIS OMA are not required to maintain paper copies of MAFs. Q24. What level of maintenance has responsibility for functions that are related to adjustments, removal and  replacements  of  parts,  and  periodic maintenance of support equipment? Q25. Records are kept on the acceptance, transfer, and custody of SE. Records are also kept on the rework,  preservation,  and  depreservation  of  SE. Further,  records  are  kept  of  TDs  and  the miscellaneous history of SE. On what record is this information concerning SE recorded? SUMMARY The  maintenance  data  system  (MDS)  is  the maintenance   information   system   that   provides statistical data on naval aircraft and equipment. Of primary interest to the AZ is the maintenance data reporting (MDR) system and subsystem capability impact reporting (SCIR) system. The MR subsystem reports all supply actions that support aircraft maintenance. AZs do NOT have direct responsibilities in maintaining the MR subsystem. The MDR subsystem of the MDS deals with the most complex range of MDS data. The MAF Copy 1 Daily Audit Report has three parts: Part I contains data that have no errors and each data element is considered valid. Part II contains records that were submitted for the current reporting period with errors that have not been previously corrected. Part III is produced when there are correction or deletion records that cannot be 5-45 applied to the local database due to erroneous data. The MDR  4-1  is  a  detailed  list  of  technical  directive compliance during a reporting period. The Aircraft/ Equipment Work Load Report is the Naval Aviation Logistics Command Management Information System (NALCOMIS) report that provides a listing of all outstanding Maintenance Action Forms (MAFs) for a specific aircraft or equipment. The  SCIR  subsystem  provides  information  about aircraft   and   equipment   inventory,   subsystem performance,  and  mission  capability  of  specific  aircraft or equipment. The status of an aircraft or equipment at the time of inventory is indicated by an inventory status code. An aircraft inventory MAF is required when an aircraft is gained or lost from the reporting custodians inventory or when the aircraft undergoes a change in material  condition  reporting  status  (MCRS).  The Equipment Master Roster, E-00, reflects the aircraft or equipment on hand as of 0001 on the 1st day of the reporting period. Maintenance control updates the E-00. SCIR-3 reports the hours in a reporting period where  equipment  was  limited  in  performing  its intended  mission. The  monthly  maintenance  summary  provides information that maintenance managers need to know. The monthly maintenance plan (MMP) for an aircraft maintenance activity provides for scheduled control of its predictable maintenance workload. The MMP for an organizational maintenance activity (OMA) must be prepared and distributed not later than (NLT) the 25th of the month prior to the month where the plan applies. A supported aviation activity uses the MAF to request work from a supporting IMA. The IMA or supply department uses a Work Request Customer Service, OPNAV Form 4790/36A, to request work from a depot-level maintenance facility. An aircraft that is not capable of performing any of its intended mission due to lack of parts or materials is described as “not mission capable supply.” The  aircraft  readiness  report  (AMRR)  identifies  the number of aircraft that are assigned to a carrier air group (CAG) and informs the aircraft controlling authority (ACC) and the type commander (TYCOM) of mission capable (MC) and full mission capable (FMC) data  as  well  as  significant  maintenance  and  supply deficiencies. Whenever oil analysis is initiated, terminated, or the monitoring laboratory changes, an entry should be made in the Miscellaneous/History record for the aircraft or equipment.
