编号系统是 ATA 三元素编号系统的扩展。编号有七个元素。前五个元素是每个任务或子任务所必需的。第六和第七元素仅在必要时使用。参见图 INTRO-3。
(b) Elements 1, 2, and 3 identify the ATA Chapter-Section-Subject number of the pageblock.
元素 1、2 和 3 标明分页块的 ATA 章-节-主题编号。
(c) Element 4 defines the maintenance function being performed. This element is a three position element. The third position is zero filled when further definition is not required. If required, the manufacturer will use the numbers 1 thru 9 or letters A thru Z, excluding the letters I and O. Refer to Table INTRO-5.
元素 4 定义正在执行的维护功能。该元素有三个位置。当不需要进一步定义时，第三个位置为零。如果需要，制造商将使用数字 1 至 9 或字母 A 至 Z，但不包括字母 I 和 O。
(d) Element 5 provides a unique identification for each TASK or SUBTASK number which is similarly numbered through the first four elements.
元素 5 为每个 TASK 或 SUBTASK 编号提供唯一标识，其编号与前四个元素类似。
– TASKS are numbered from 801 thru 999
– 任务编号为 801 至 999
