60.10 Table BJ, Failure Mode Indicator Mission Phase Code Characteristics Narrative. This table may be used to identify Compensating Design Provisions and Compensating Operator Actions. Table keys consist of EIAC (EIACODXA), LCN (LSACONXB), ALC (ALTLCNXB), LCN Type (LCNTYPXB), Failure Mode Indicator

a. If the Failure Mode Indicator Mission Phase Characteristics Narrative Code (FMMPCNBJ) is (A), then this table describes compensating design provisions which circumvent or mitigate the effect of the failure (Compensating Design Provisions, DED 049).

b. If the Failure Mode Indicator Mission Phase Characteristics Narrative Code (FMMPCNBJ) is (B), then this table describes compensating operator action provisions which circumvent or mitigate the effect of the failure (Compensating Operator Action Provisions, DED 050).

60.11 Table BK, Reliability, Availability, and Maintainability Criticality. This table sums up the failure mode criticality numbers related to the failure modes of an item within specific safety hazard severity classification (SHSC)

APPENDIX A

b. Unscheduled task codes, task interval code “G” (2d position of the task code), must have a MB entered which corresponds to the MB for the AOR. For this reason, the AOR LCN (AORLCNCA), AOR ALC (AORALCCA), AOR LCN Type (AORTYPCA), and the AOR MB (AORMSBCA) must match with a set of key values already established in Table AG.

c.Every Task Code (TASKCDCA) must have a Task ID (TASKIDCA).

d.Secondary Means of Detection (SMDTECCA) is not allowed without Primary Means of Detection (PMDTECCA).

e.For Performance Standards A, B, and C (PRSTDACA, PRSTDBCA, and PRSTDCCA), and Task Conditions A, B, and C (TCONDACA, TCONDBCA, and TCONDCCA),

enter a “Y” or “N”.

f.Every task code requires a corresponding task frequency.

g.If the Facility Requirement Code (FTRNRQCA) is “Y”, the Facility tables (F tables) should be addressed.

h.Up to four Training Location Rationale (TRNLOCCA) codes may be entered for each unique combination of LCN, EIAC, ALC, LCN Type, and task code (codes must be entered in a continuous string).

i.Up to four Training Rationale (TRNRATCA) codes may be entered for each unique combination of LCN, EIAC, ALC, LCN Type and task code (codes must be

entered in a continuous string).

j. Measured Mean Man-Hours (MSDMMHCA) are calculated by summing the Mean Man-Minutes (SUBMMMCD) per Person ID for the given task (see DED 225) and dividing by 60.

k . Measured Mean Elapsed Time (MSDMETCA) is calculated by summing the Mean Minute Elapsed Times (SBMMETCB) for all subtasks of a task (see DED 224).

l.Items entered which have task function codes (lst positon of task

code) of W, E, G, K, L, R, H, and J must have physical LCNs (LCN Type of “P”).

m. Task Frequency (corrective) shall be calculated based on Failure Mode Ratio (Table BF), Failure Rate (Table BD), Mean Time Between Maintenance Induced (Table BD), Mean Time Between Maintenance No Defect (Table BD), Conversion Factor (Table BA), and Annual Operating Requirements (Table AG). Task Frequency (preventive) shall be calculated based on Annual Operating Requirements (Table AG), Conversion Factor (Table BA), Maintenance Interval (Table BH), or Task Interval Code (Table CA). A change in any of these variables shall result in an update of Task Frequency (Table CA).

70.2 Table CB. Subtask Requirement. This table contains data related to the subtask level such as Work Area Code and Mean Minute Elapsed Time. All task narrative will be written at the subtask level, then rolled into the task level. It is possible to reference subtask descriptions within this table. Table keys consist of LCN (LSACONXB), LCN Type (LCNTYPXB), ALC (ALTLCNXB), EIAC (EIACODXA), Task Code (TASKCDCA), and Subtask Number (SUBNUMCB).

a. For referencing purposes, Referenced Subtask Number (RFDSUBCB), Referenced Subtask Task Code (RFDTCDCB), Referenced Subtask LCN (RFDLCNCB), Referenced Subtask ALC (RFDALCCB), Referenced Subtask LCN Type (RFDALCCB), and Referenced Subtask EIAC (RFDEIACB) must be included as nonidentifying keys. This referencing capability should only be used when the data of this table and the subordinate tables SEQUENTIAL TASK DESCRIPTION and SUBTASK PERSONNEL REQUIREMENTS (tables CC and CD) are the same for referenced and referencing subtasks. All non-key attributes in table CB and it’s subordinate tables (CC and CD) are pulled from the referenced subtask and it’s subordinate tables.

APPENDIX A

Keys from table CB migrate down to tables CC and CD. Additional keys needed for tables CC and CD are pulled from referenced subtask tables CC and CD.

b. Subtask Numbers shall begin with 001 and run through 999 for each unique set of keys (e.g., EIAC, LCN, ALC, LCN Type, and task code). Skips are allowed when assigning subtask numbers.

70,3 Table CC, Sequential Subtask Description. This table contains the sequential task narrative entered at the subtask level. The narrative will be entered in a step-by-step basis in order to document all subtasks required to perform the task under analysis. Subtasks should be detailed and sequenced to eliminate possibilities of technically incorrect procedures. Elements are subordinate to subtasks. All requirements for power, compressed air, and environmental considerations will be specified. Qualifying notes must be

but are not needed until later in the task) should be documented in the first subtask. Similarly, notes and warnings for close-down of a task should be documented in the last subtask. In cases of multi-personnel tasks, the communication and coordination requirements between personnel must be documented (i.e., communication and coordination between individuals in one crew area with individuals in another area). Table keys consist of LCN (LSACONXB), LCN Type (LCNTYPXB), ALC (ALTLCNXB), EIAC (EIACODXA), Task Code (TASKCDCA), Subtask Number (SUBNUMCB), and Text Sequencing Code (TEXSEQCC).

a. The Element Indicator “E” is documented against the first line of a given element narrative and is blank for all subsequent lines of that element narrative.

b. Element narratives must begin on unique lines (Text Sequence Codes). For example, one element cannot end on line 12 and the next element begin on line 12 also.

APPENDIX A

NOTE: Every Task Remark Reference Code and Task Remark combination is unique across all rows of information for a given EIAC. In other words, for the same

EIAC, a given Task Remark Reference Code can only correspond to one Task Remark statement throughout the file structure.

70.6 Table CF. Task Remark Reference. This table serves as a tie-in table between the TASK REQUIREMENT table (CA) and the TASK REMARK table (CE). Table keys consist of LCN (LSACONXB), LCN Type (LCNTYPXB), ALC (ALTLCNXB), EIAC (EIACODXA), and Task Code (TASKCDCA), which are migrated from table CA and the Task Remark Reference Code (TSKRRCCE), which migrates from table CE. EIACODXA from tables CA and CE must always be identical, therefore, duplication of that key in this table is not needed.

70.7 Table CG. Task Support Equipment. This table contains information which relates data needed for the task under analysis to the Support Equipment (SE) tables. This table serves as the tie-in between Task Analysis and SE areas for data which is to be incorporated into the LSA-070 series of reports (e.g., LSA-070, 072, 074, etc.). Table keys consist of LCN (LSACONXB), LCN Type (LCNTYPXB), ALC (ALTLCNXB), EIAC (EIACODXA), Task Code (TASKCDCA), Task Support Reference Number (TSFEFNCG), and Task Support CAGE Code (TSCAGECG).

a.In a given row, Quantity Per Task and Quantity Per Task Unit of

Measure must either both be blank, or both have entries.

b. Based on the definitions for Item Category Codes (ICC) (DED 177), it is recommended that only items which fall under the following ICCs (identified

c. If the Training Equipment Requirement Code (TRNRQCCA) in table CA is “Y”, upport equipment item identified by the Task Support Reference Number (TSREFNCG) must have an ICC (SEICCDEA) of “AF” entered against it in the EA table (match TSREFNCG and TSCAGECG with SEREFNEA and SECAGEEA, then check ICC).
