European foreword
This document (EN 9131:2020) has been prepared by the Aerospace and Defence Industries
Association of Europe - Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this Standard has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2021, and conflicting national standards shall
be withdrawn at the latest by January 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
This document supersedes EN 9131:2016.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
Rationale
This standard was created to provide for the uniform submittal of nonconformity information for
notification and/or approval when contractually invoked at any level or as guidance within the aviation,
space, and defense industry. This standard can be invoked as a stand-alone requirement or used in
conjunction with 9100-series standards (i.e., EN 9100, EN 9110, EN 9120).
Foreword
To assure customer satisfaction, aviation, space, and defense organizations must provide, and
continually improve, safe, reliable products and services that meet or exceed customer and applicable
statutory and regulatory requirements. The globalization of the industry, and the resulting diversity of
regional and national requirements and expectations, have complicated this objective. Organizations
have the challenge of purchasing products and services from external providers throughout the world
and at all levels of the supply chain. External providers have the challenge of delivering products and
services to multiple customers having varying quality requirements and expectations.
The aviation, space, and defense industry established the International Aerospace Quality Group (IAQG)
for the purpose of achieving significant improvements in quality and safety, and reductions in cost,
throughout the value stream. This organization includes representation from companies in the
Americas, Asia/Pacific, and Europe.
This document standardizes requirements for nonconformity data definition and documentation for the
industry. The establishment of common requirements, for use at all levels of the supply-chain by
organizations, should result in improved quality and safety, and decreased costs, due to the elimination
or reduction of organization-unique requirements and the resultant variation inherent in these multiple
expectations.
1 Scope
1.1 Application
This document defines the common nonconformity data definition and documentation that shall be
exchanged between an internal/external supplier or sub-tier supplier, and the customer when
informing about a nonconformity requiring formal decision. The requirements are applicable, partly or
totally, when reporting a product nonconformity to the owner or operator, as user of the end item (e.g.,
engine, aircraft, spacecraft, helicopter), if specified by contract.
Reporting of nonconformity data, either electronically or conventionally on paper, is subject to the
terms and conditions of the contract. This also includes, where applicable, data access under export
control regulations.
1.2 Purpose
The process of exchanging, coordinating, and approving nonconformity data via concession or product
quality escape varies with the multiple relationships and agreements among all parties concerned. The
information provided by this document forms architecture for submitting and managing data that
allows for concise and accurate communication using various documented methods. The main objective
of this document is to provide the definition of a data set that can be integrated into any form of
communication (e.g., electronic data interchange, submission of conventional paper forms).

3 Terms and definitions
Definitions for general terms can be found in EN ISO 9000 and the IAQG International Dictionary
(located on the IAQG website).
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
 ISO Online browsing platform: available at http://www.iso.org/obp
 IEC Electropedia: available at http://www.electropedia.org/
3.1
customer
recipient of a product provided by an internal/external supplier or sub-tier supplier
3.2
mandatory data
common and transferable data systematically filled in and provided; if printed, this field shall be
included on the printed form
3.3
optional data
all data fields that are not defined as mandatory by this standard; these fields may be requested by a
customer or needed by the originator for their own purposes
3.4
product
output of an organization that can be produced without any transaction taking place between the
organization and the customer
Note 1 to entry: Production of a product is achieved without any transaction necessarily taking place between
provider and customer, but can often involve this service element upon its delivery to the customer.
Note 2 to entry: The dominant element of a product is that it is generally tangible.
Note 3 to entry: Hardware is tangible and its amount is a countable characteristic (e.g. tyres). Processed
materials are tangible and their amount is a continuous characteristic (e.g. fuel and soft drinks). Hardware and
processed materials are often referred to as goods. Software consists of information regardless of delivery
medium (e.g. computer programme, mobile phone app, instruction manual, dictionary content, musical
composition copyright, driver's license).
EXAMPLE vehicle, engine, equipment, component, deliverable software, or parts and materials thereof

3.5
product quality escape
any product released by an internal/external supplier or sub-tier supplier, that is subsequently
determined to have one or more nonconformities to contract and/or product specification require-
ments, that have not been positively dispositioned prior to delivery
3.6
concession
documented authorization from the customer to the internal/external supplier to use or release a
product which does not conform to the specified requirements
Note 1 to entry: Concession and product quality escape differ with respect to the point in time when a
nonconformity is detected during the product life cycle. Concession is evident before delivery to the customer,
while a product quality escape is identified after delivery to the customer.
