Crew Leader The crew leader is a second or senior third class petty officer.. This person is responsible for ensuring the job gets done. When assigned a job, the crew leader must determine what member of the crew is to do what work, what tools and repair parts are required, identify special  safety  precautions  to  be  observed,  and  what priority the job has. A crew may be assigned more than one job at a time. Once the job is assigned, it is the crew leader's "baby." The crew leader is also responsible for ensuring that crew time is reported, that all materials used on the job are recorded, and that any unscheduled repairs are reported to the shop supervisor. Inspector Inspectors examine equipment for needed repairs and  services.  They  work  directly  for  and  are responsible  to  the  maintenance  supervisor.  Inspectors should  be  first  class  or  senior  second  class  petty officers. They must be knowledgeable and proficient in their rating, and they should be able to describe each repair action on the ERO clearly. 1-2 Before  the  initial  inspection  is  performed,  an inspector should review the equipment history jacket. The  inspector  is  responsible  for  reviewing  previous EROs for follow-up adjustments from previous repairs and  maintenance  schedule  and  lubrication  charts  to initiate hourly/mileage repairs or adjustments. He also reviews the DTO file for parts recieved to perform deferred repairs. Inspectors may perform minor work that pertains to inspection procedures only. Inspectors should inform the maintenance supervisor of suspected equipment abuse or misuse and recurring component failures   immediately. Each piece of equipment is inspected after repairs are  completed  to  ensure  that  the  work  was  done correctly.  Thorough  final  inspection  increases reliability and reduces the mechanic’s work load. Cost Control Supervisor The cost control supervisor is usually a first class petty officer who is responsible for adminstrative control of the equipment maintenance program. The cost   control   supervisor   works   directly   for   and responsible  to  the  maintenance  supervisor.  The  cost control supervisor directly supervises the PM clerk, the DTO  clerk,  the  tool  custodian,  and  the  technical librarian. Some  of  the  cost  control  supervisor’s responsibilities are to draft all maintenance related correspondence such as monthly CESE reports, receipt messages  and  letters,  disposal  letters,  1348s  and material-handling equipment (MHE) reports. The cost control supervisor also, completes EROS, forwards downloads to 3rd NCB equipment office, tracks daily and weekly equipment availability, maintains the deadline  equipment  file,  and  NORS/ANORS  status board. Preventive Maintenance Clerk The preventive maintenance clerk controls the PM program directed by the maintenance supervisor. The PM clerk places all CESE into PM groups, prepares the PM schedule, and maintains the PM record cards with the preventive maintenance history of each vehicle. The PM  clerk  is  responsible  for  controlling  EROS. maintaining the ERO log, maintaining and updating equipment  history  jackets,  and  updating  equipment status boards in the maintenance office. The PM clerk also summarizes the total cost of repairs and of labor expended and makes appropriate entries on the ERO. Direct  Turnover  Clerk The direct turnover (DTO) clerk maintains the maintenance   shop’s   repair   parts   status   and accountability records and is a liaison between the supply office and the shop. All requisitions for Not-in- Stock (NIS) and Not-Carried (NC) material must pass through the DTO clerk who maintains the DTO log and repair parts summary sheets. The DTO clerk also maintains the deadline file and deadline status board. Technical  Librarian Technical  librarians  are  responsible  for  the prepacked   library   that   contains   operational, maintenance, and parts manuals. They establish and enforce check-out procedures for the manuals and initiate  parts  requisitions  (NAVSUP  1250s  and  DD Form 1348s). The task of researching and preparing the requisitions  is  handled  by  the  technical  librarian,  so  the floor mechanics can perform maintenance functions.
