About AIA/ASD S5000F

International specification for in-service data feedback


With the introduction of new and complex technical products, a proper support system must be made available in a timely manner. This requires a proper product surveillance in order to fulfillthe product liability regulations and to ensure a proper and optimal exploitation of product capabilities. A process for information feedback thus becomes necessary so as to ensure cost-efficient and optimised operation of the product. Over the life cycle of a complex technical system or product, support costs are much higher than the acquisition costs. Therefore this specification is a prerequisite for cost saving and optimized product exploitation. It describes the relevant data flow for the involved parties and information feedback when the data is analyzed and turned into recommendations.


The specification S5000F has been designed to cover the information that is required to be fed back to both ILS and other domains. It should be kept in mind that in-service data feedback is one of tthe most important functions of in-service support. It enables fleet and support managers and technical syste manufacturers t perform a thorough analysis of operational and maintenance performance.

The results of this analysis can be the basis for:

  • § Enhancement of the maintenance and support concept

    § Improvement of the product by modifications and retrofit activities

    § Sophisticated operational planning

    The overall aim to be achieved by operational and maintenance data feedback is the increase of fleet and product availability and optimization of effectiveness.

    In addition, feedback information is a firm requirement by industry to agree to and manage performance-based logistic (PBL) contracts where the contractor takes over part or the full maintenance of the product and fufills his obligations regarding product liability.

    The purpose of using S5000F alone or together with other S-Series ILS specifications is to obtain a structured way to handle the operational and maintenance data feedback from the operator. By using the data model of S5000F (and the common data model for the S-Series of ILS specifications, SX002D) this can be performed in an efficient way.

S5000F specification development history

The development work was allocated in the year 2008 to an international team of experts working under the joint chairmanship of AIA and ASD representatives. The following companies and organizations contributed to the work:

AgustaWestland United Kingdom
Airbus Defense and Space Spain (former Airbus Military) and Germany (former Cassdian)
Andromeda Systems, Inc. USA
Boeing USA
Dassault Aviation France
Bundeswehr  Germany
ESG Germany
OCCAR European (based in Germany)
Rolls-Royce United Kingdom
Saab AB Sweden
UK MoD United Kingdom

A first draft of the specification (Issue 0.1) was officially published in December 2013 internally to ASD and AIA member companies. The main purpose of this publication was to enable experts from interested companies and organizations to provide comments on the first approach to the S5000F expert team..

A second draft (issue 0.2) was published in June 2014 to the public at large, so as to receive a more extended feedback. BAsed on the received comments draft 0.3 was published in March 2016.

The first formal release, Issue 1.0, was published in September 2016.

Brief description and outline

S5000F describes the basic in-service feedback processes, as well as as the activities to be performed during the in-service phase and the information that these activities require for their proper execution. Thus, the data to be fed back is directly related to activities and their need is evidenced if such activities have to be carried out. For simplicity, these activities have been summarized in typical use cases, and the feedback data have been mapped against these use cases. S5000F can therefore be used contractually, by selecting the activities (use cases) to be performed and referencing to the tables that list the information that is required to perform such activities.

The specification is organized into 20 chapters, each of them addressing a specific feedback purpose or proving the global-level information:

Chapter 1 Introduction and general guidance on how to use the Specification
Chapter 2 The in-service feedback business process
Chapter 3 Feedback data for the purpose of reliability, availability, maintainability and testability analysis
Chapter 4 Feedback of data for maintenance analysis
Chapter 5 Feedback of safety data
Chapter 6 Feeback of data for supply support
Chapter 7 Feedback for Life Cycle Cost analysis
Chapter 8 Feedback of data for warranty analysis
Chapter 9 Feedback of data for the purpose of platform usage and health monitoring
Chapter 10 Feedback of data to support obsolescence management
Chapter 11 Feedback of data for integrated fleet management
Chapter 12 Feedback of data for configuration management
Chapter 13 Feedback of data to support the management of service contracts
Chapter 14 Feedback of non-predefined information
Chapter 15 Data model
Chapter 16 Data exchange
Chapter 17 Data element list
Chapter 18 Tailoring and contracting against S5000F
Chapter 19 Data required for the different use cases
Chapter 20 Terms, abbreviations and acronyms

S5000F interoperability with other S-series ILS specifications

A significant effort was carried out so as to ensure that S5000F is interoperable since the beginning with the other S-Series ILS specifications.

S5000F is fully interoperable with S3000L issue 1.1, as well as with S2000M Issue 6.0 and the next issue of S4000P. Coordination is also performed with SX000i so as to ensure that the feedback corresponds to the activities defined in the global ILS framework. Similarly, S5000F is since the beginning fully interoperable with the S-Series Common Data Model (SX002D) Issue 1.1 and has included even elements of the future Issue 2.0. The interoperability with other S-Series specifications (S1000D, future S6000T) is also being monitored, so as to include them is future issues of S5000F.

Similarly, the data environment is described by a detailed relationship model using standard UML technology (based on ISO Standard 10303, AP239, PLCS). This will allow in the medium term to integrate feedback data not only with ILS, but also with Engineering, using the ISO STEP standards. The goal is not to have an isolated feedback specification, but to integrate in a set of ILS, engineering and manufacturing specifications so as to achieve a true global lifecycle data exchange.

S5000F specification comments

The current version of S5000F is a draft sent out for public comment, and therefore any comments, questions of suggestions for improvement can be forwarded to the S5000F Steering Committee. For this purpose, register in the common ILS specification commenting tool and submit any proposed issues. Details can be found in Chapter 1.

Relationship with other specifications

The realtionship of S5000F with other ASD specifications is described in SX000i, ILS Guide. These other specifications can be found on their respective websites, which are listed in our Links page.. An overview of the S-Series Suite of ILS Specifications can be found here.
