About S4000P

Purpose:

The main purpose of this specification is to assist regulatory authorities and all parties involved in the analysis process in developing and releasing initial Preventive Maintenance Task Requirements (PMTR) and intervals for new Products prior entry into service. S4000P analysis methodologies remain applicable for later optimizations/modifications of the Product design in Product systems and/or of Product structure and/or of Product zones.
Once developed, authorized and packaged into interval clusters in a Product OMP, the S4000P In-Service Maintenance Optimization (ISMO) process enables the mechanism for continuously improving Product maintenance during its in-service phase.
Every development or improvement of a preventive maintenance task for a Product supports at least one of the following aspects:

  • Ensure / maintain Product safety, including safety/emergency systems and/or emergency equipment,
  • Avoid any conflict with law and/or significant impact on environmental integrity (ecological damage) during Product mission/operation and/or maintenance,
  • Optimize mission/operational capability/availability of the Product,
  • Optimize Product economy (Life Cycle Costs = LCC).

S4000P main advantages and innovations:

  1. In comparison to other known analysis methodologies, the application of ASD S4000P is not limited to pre-defined Product types like on military or civil aircraft only. The S4000P analysis principles are developed by industry to be applicable for all complex technical Products. This comprises Products on air, on ground, under the ground, on sea, under the sea level or even in space for civil and/or military usage.
  2. To cover the whole Product life cycle, S4000P provides the innovative ISMO methodology to prove and optimize the Product maintenance during its complete in-service life in addition to the Product maintainability analysis that has to take place during the design and development phase provided as Engineering/Design Support.
  3. When defining preventive maintenance tasks, the S4000P Product system analysis takes into account Product-integrated test- and condition monitoring technology being realized more and more in modern Products.
  4. The S4000P Product structure analysis covers all kind of present and of future Product structure materials and material combinations.
  5. The S4000P Product zonal analysis is based on a modular analysis concept to cover the zonal analysis of all kind of Product types.
