table, first determine in which quarter after overhaul the MR will be first scheduled. Go to this quarter in the first row of the table. Then schedule the MR for the quarters in that column as applicable. For example, if an 18M-1 is scheduled for the 4th quarter after overhaul, it must also be scheduled for the 10th, l6th, and 22d, as applicable. NOTE Prior  to  scheduling  30M,  36M,  48M,  or 60M,  review  the  MRC  to  see  if  a  specific quarter after overhaul is indicated. (4)  Ships with overhaul cycles of less than 24 quarters must schedule cycle requirements  within  this  operational time  frame.  Ships  delayed  beyond  24 quarters must extend their Cycle PMS Schedule  by  adding  quarter  numbers in  the  Schedule  Quarter  After  Over- haul  As  Indicated  column.  (Multiple month   requirements   needed   before entering  overhaul  must  be  reviewed and rescheduled as necessary.) b. In  the  Each  Quarter  column,  list  every  2 weeks,   monthly,   every   2   months,   and quarterly maintenance requirements (2W-1,  M-1,  2M-1,  Q-1,  and  so  on),  and situation requirements (M-IR, Q-IR, S-IR, A-IR,  18M-IR,  R-1,  and  so  on).  Daily, every  2d  day,  every  3d  day,  and  weekly maintenance  requirements  are  not  listed here. 4. Have   the   completed   Cycle   PMS   Schedule reviewed, signed, and dated by the department head. 5. Once the Cycle Schedule has been completed, maintenance  requirements  listed  are  not  to  be moved from one quarter to another. If rescheduling  becomes  necessary,  reflect  it  on the Quarterly PMS Schedules. 6. All superseded cycle schedules will be retained for 12 months. QUARTERLY PMS SCHEDULE The   Quarterly   PMS   Schedule   (OPNAV   Form 4790/14)  (fig.  7-11)  displays  each  workcenter's  PMS requirements    to    be    performed    during    a    specific 3-month period. This schedule, when updated weekly, provides a ready reference to the current status of PMS for   each   workcenter.   This   schedule   represents   a departmental  directive  and,  once  completed,  may  be changed   only   at   the   department   head's   discretion. Responsibility  for  changes  is  sometimes  delegated  to division officers on carriers and cruisers. Contents of the Quarterly PMS Schedule The Quarterly PMS Schedule contains the following:   Space  is  provided  for  entering  the  workcenter, year,  quarter  after  overhaul,  department  head's signature, date prepared, and months covered.   Thirteen  columns,  one  for  each  week  in  the quarter,  are  available  to  permit  scheduling  of maintenance  requirements  on  a  weekly  basis throughout   the   quarter.   Additional   columns provide space to enter the complete MIP codes and any PMS requirements that may be required to be rescheduled into the next quarter. Take care to ensure that rescheduling changes conform to the periodicity specified for the requirement.
