30.18.3 The calculations for technical factors are computed as follows:

MRF = [MTD(D) + MTD(CAD)] X MRR (Repairable)

Numeric Stockage Objective (NSO) - RMSS LVL (DED 329)

BDSR = MTD(CBD) X MRR

where;

MTD = Maintenance task distribution MTD(F) = Second subfield of the MTD MTD(H) = Third subfield of the MTD MTD(D) = Fifth subfield of the MTD MTD(CBD) = Sixth subfield of the MTD MTD(CAD) = Seventh subfield of the MTD MRR = Maintenance Replacement Rate

30.18.4 Part II interchangeability/replaceability (I/R) code is determined based on the interchangeability code (IC) entered in table HP:

30.18.5 Part III, Requirement Number (REQ NO) is a five position counter (first four positions are numeric and the last position is alphabetic), which is generated based on the type of task being displayed. The counter begins at 0001 for each type of task and the alpha codes consist of P (preventive), C (corrective), T (servicing), and U (calibration).

30.18.6 Part I is sequenced by ascending LCN or FGC (depending on display

APPENDIX B

The MRRII is calculated using the following formula:

MRRII = MRRI X MRRI/MRRII ratio (selected).

30.21.3 When failure rate, mean time between maintenance (MTBM)-induced, and MTBM-no defect are reported, each value is preceded by (M), (P), (A), or (C) to indicate measured, predicted, allocated, and comparative analysis values, respectively. Where a measured value has not been entered, the report will default to the predicted, then allocated, and finally comparative analysis.

30.21.4 The report is sequenced by ascending values of LCN for a given task code, then ascending task codes. This holds true for the assembly LCN, repair part LCN, and task LCN. For the reliability, availability, and maintainability (RAM) LCNs, they are sequenced in ascending value, then by failure mode indicators (FMI).
