3.13Block 13. Periodicity.Enter the periodicity of this task from block 13 of the Maintenance Requirements Index (MRI) form. For PMS MRCs, enter a two-segment code; e.g., "4416 Q-2", "7211 Q-1", and "2331 R-1". The first segment is the ESWBS/MIP series code which will be provided by the applicable MCA. The second segment is the task periodicity. Identify MRCs applicable to more than one MIP series and enter each MIP series into block 13. The ESWBS and Class Maintenance Plan (CMP) maintenance requirement periodicity shall be entered in months.

3.14Block 14. PMS MRC Rates and Man-Hours.Identify and enter, by rating and rate, the number of persons required to perform the maintenance requirement and the man-hours required for each person. Additional entries in this area shall be included as follows:

3.14.1The Navy Enlisted Classification (NEC) shall be entered if special skills are required.

3.14.2When both NEC and rates are important to the task, both shall be included; e.g., GM2, with the NEC 0876 listed beneath the rate.NECs shall not be in parentheses; multiple NECs shall be separated by a slash (/).

3.14.3Titles for officers shall be the first entry in the block when applicable; e.g., "Damage Control Assistant (DCA)", "Electronic Material Officer (EMO)", "Engineering Officer (Eng. Off.)."

3.14.4In cases where more than one rating is required, ratings shall be listed after the officers descending by rate within each rating category; e.g., "Eng. Off.", "Electrician's Mate First Class (EM1)", and "Machinist's Mate Second Class (MM2)."

3.14.5When more than one person is required for a particular rate, the appropriate number shall precede the rate; e.g., "2 Operations Specialists First Class (2 OS1)", "2 Sonar Technicians Surface First Class (2 STG1), and 3 Electronics Technicians Second Class (3 ET2)."When more than one person of the same rate are required and their time requirements are not equal, each person shall be listed separately. When additional personnel are required because of safety regulations, the rate and number of such personnel shall also be included.

3.14.6In cases where either of two similar ratings can be assigned the work on an MRC, both ratings shall be listed and separated by a slash; e.g., "Fire Control Technician First Class (FC1)/Electronics Technician First Class (ET1)", "Gunner's Mate Second Class (GM2)/Gunner's Mate Missiles Second Class (GMM2)."

3.14.7Calendar periodicity and "R" periodicity MRCs shall include the necessary rates to perform the maintenance.Inactive Equipment Maintenance (IEM) procedural MRCs shall also include rates. MRCs with a U periodicity shall include rates when so directed by the MCA.

3.14.8Man-hours (M/H) (converted to hours and tenths of an hour) shall be entered immediately to the right of each rate in the RATES area.When the M/H figure is less than one hour, a zero shall appear before the tenths of an hour portion; for example, "0.1" and "0.4." When an officer is required, no M/H shall be assigned for that person.

3.14.9The time entered shall indicate the M/H required for each rate as if they were performing their tasks independently.When more than one of the same rating and rate are required and their time requirements are equal, the M/H will be the sum of their time requirements. When more than one person of the same rating and rate are required and their requirements are not equal, each person shall be listed separately.

3.14.10Equipment warm-up time of up to 30 minutes shall be included in the assigned M/H, block 14.Warm-up time in excess of 30 minutes, as well as periods not requiring maintenance technician intervention (i.e. charge batteries for 24 hours) shall not be included unless the maintainer is required for constant observance.
