S4C6 - SPECIAL TECHNICAL INSTRUCTIONS
Table of Contents
1. A Special Technical Instruction (STI) provides a means for a Systems Program Office (SPO) to issue an urgent engineering and maintenance instruction to AMOs. STIs are limited to technical matters of priority or safety which cannot be satisfied by, or actioned within the timeframe necessary to process a publication amendment, or a Modification Order.
2. This chapter prescribes the requirements for an AMO to effectively manage an STI.
3. An STI is readily identifiable by a ‘Warning Page’ hatching around the page border.
4. An STI will normally belong to a series allocated in accordance with the sponsor SPOs STI identification system. The STI will be numbered sequentially within the applicable series, and released in numerical order to facilitate tracking and filing.
5. Released STIs have a status of either ‘Active’ or ‘Cancelled’. A STI is ‘Active’ until all action is complete, or is superseded by a new or amended STI, after which it becomes ‘Cancelled’. The status of released STIs is promulgated by means of a Consolidation Index.

However, the SMM or delegate must notify, and should seek SPO advice in making the assessment prior to deferring the STI.
10. In the event the SMM or delegate is unable to contact the relevant SPO, the SMM or delegate must complete the assessment and notify the SPO of the STI deferral at the first available opportunity.
