S4000P – International specification for developing and continuously improving preventive maintenance

 

Introduction:

For a new Product or Product variant, the maintainability of the intended Product design must be assessed by Engineering Support specialists based on their in-service experience.
Preventive maintenance task requirements (PMTR) with intervals and/or redesign requirements must be determined in parallel to the Product design process and must be available prior to Product design-freeze milestones (latest prior to the critical design review (CDR) of the Product).
According to the ASD scope, S4000P must cover all kind of Product types including any complex technical platform, system, equipment or facility (eg. on air/sea/land, under sea, under ground, in space).
The S4000P analysis methodologies allow a structured, traceable and complete determination of PMTR with intervals for a Product, which are the basis to elaborate and document a Product maintenance program / Operator Maintenance Plan (OMP) prior to start the Product in-service phase.
During the Product in-service phase, S4000P provides an additional process that allows to review the completeness and effectiveness of preventive maintenance tasks from a Product OMP taking into account Product in-service experience and the state-of-the-art analysis methodologies. That review of the OMP is again fully traceable and applicable for all Products types.
Every S4000P analysis methodology or process must be tailored and precised for a Product under analysis in a guideline or handbook to be acceptable to regulatory authorities, maintainers, operators, manufacturers and suppliers.

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:
