In spite of the system safety enhancements provided by the SEP program and continuing improvement efforts in ATOS, pre-ATOS carriers (non-top-ten) still must use traditional tools to conduct surveillance. Risk analysis is conducted using the ATOS elements but the resulting action plan must still be planned and assigned using PTRS activity codes, necessitating a translation. Once collected, another translation of the data must be made to conduct subsequent analyses. Furthermore, while new entrant carriers can be certificated using the ATOS design tool, the Safety Attribute Inspection (SAI), performance assessments of these elements must also be conducted largely with PTRS activities, even it the ATOS performance tool, the Element Performance Inspection (EPI) is used as a checklist. It is highly desirable to use a consistent set of tools throughout a carrier's oversight program. Likewise, it is also desirable to use a standardized set of tools across the Part 121 industry.
Based upon these limitations and the objective of further expanding the ATOS program, Flight Standards is considering moving the SEP program forward to SEP IV, where ATOS SAI's and EPI's will be used directly. The third dotted line on the graphic, as well as the earlier two, show how the ATOS and pre-ATOS programs are being tracked to bring increasing commonality of methods and tools.
During the FY01-03 timeframe, deployment of the 1.x DCT's and mod 7/8 at the top tem CMT's should also be completed.
