Rationale
This European Standard has been significantly revised further defining process requirements and data
expectations; restructuring the nonconformity documentation data and providing further definition of
data descriptions; and providing process defect, cause, and corrective action codes.
This European Standard was created to provide for the uniform submittal of nonconformance
information for notification and/or approval when contractually invoked at any level or as guidance
within the aviation, space, and defence industry. This European Standard can be invoked as a stand-

alone requirement or used in conjunction with 9100-series standards (i.e., 9100, 9110, 9120).
To assure customer satisfaction, aviation, space, and defence industry organizations must produce, and
continually improve, safe, reliable products that meet or exceed customer and regulatory authority
requirements. The globalization of the industry, and the resulting diversity of regional/national
requirements and expectations, has complicated this objective. End-product organizations face the
challenge of assuring the quality of, and integrating, product purchased from suppliers throughout the
world and at all levels within the supply chain. Industry suppliers and processors face the challenge of
delivering product to multiple customers having varying quality expectations and requirements.
The aviation, space, and defence 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 nonconformance 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
This European Standard defines the common nonconformance 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.
The process of exchanging, coordinating, and approving nonconformance data varies with the multiple
relationships and agreements among all parties concerned. The information provided by this European
Standard forms guidelines for submitting and managing of data through accurate communication. The
main objective 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).
Reporting of nonconformance 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.
2 Normative References
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
EN 9100, Quality Management Systems — Requirements for Aviation, Space and Defence Organizations
EN 9110, Quality Management Systems — Requirements for Aviation Maintenance Organizations
EN 9120, Quality Management Systems — Requirements for Aviation, Space and Defence Distributors
ISO 9000:2005, Quality management systems — Fundamentals and vocabulary
3 Terms and Definitions
For the purposes of this document, the terms and definitions given in ISO 9000 and the following apply.
3.1 Customer
The 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. The data field must be printed out
on the paper form.
3.3 Optional Data
All data fields that are not defined as mandatory by this European Standard. These fields may be
requested by a customer or needed by the originator for their own purposes.
3.4 Product
Any 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 be nonconforming to contract and/or product specification requirements
3.6 Waiver/Concession
Written 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: Waiver/concession and product quality escape differ with respect to the point in time
when a nonconformance is detected during the product life cycle. Waiver/concession is evident before
delivery to the customer, while a product quality escape is identified after delivery to the customer.
4 Requirements
4.1 Data related to the description of a nonconformity (i.e., content, format, size) shall be in
accordance with the complete set defined in Annex A and the contractual requirements.
a. Mandatory data fields, identified in bold text and marked with an asterisk (*) shall be
systematically recorded and reported to the customer.
b. Optional data fields shall be recorded, when required, provided that it is not in contradiction
with contractual requirements.
NOTE 1 For any data field, whether mandatory or optional data, recorded and reported to the customer
that is not applicable shall have N/A entered in the field, prior to final approval/signature.
NOTE 2 Customers may require different optional data fields be recorded and reported. It is therefore
recommended to ensure the Information Technology System is capable of modifying the
optional data fields and inactivating those not being used to be able to fulfil new customer’s
requirements and where existing customers change their requirements. This includes the
capability of the Information Technology System to process with data types and data sizes
specified in this standard.
4.2 Nonconformity data recording and approval shall be in accordance with contractual and
regulatory requirements.
4.3 Attached files should be in a protected format (e.g., pdf, tif, jpg), whenever possible. Where this is
not practical, appropriate precautions shall be taken to prevent inadvertent changes.
4.4 Where file sizes are constrained, file size optimization tool shall be used. If a file compression is
not capable of meeting file size constraints, the data exchange has to be agreed upon between
both parties [e.g., via compact disk, USB flash drive, e-mail correspondence, direct access to data
system].
4.5 A nonconformance form shall contain, at a minimum, the fields defined in Annex A and depicted
in the example provided (see Annex B). However, the size and order of the fields may be changed
to suit the individual application provided that:
a. The contents of the boxes specified in this European Standard are maintained; alternatively a
cross reference can be used.
b. The form is identified as a nonconformance record.
c. Complies with contractual/regulatory requirements.

4.6 When required, continuation/additional sheets and attachments shall include the same reference
number as the original document.
NOTE Reference Annex A, the data fields ‘Nonconformance Description’ (see No. 19) and ‘Disposition’
(see No. 25) may be presented either as a summary or in a clearly defined sub-structure (see No.
19 a-i and No. 25 a-e).
4.7 The forms may be pre-printed, computer generated, or accessed via a net-based system
(intranet/internet), but in all cases, the printing of lines and characters shall be clear and legible.
The details entered on the forms shall preferably be machine/computer printed, but may be
handwritten as long as capital letters are used and the document remains legible.
NOTE The use of abbreviations should be kept at a minimum.
4.8 The information shall be in English, but other languages are acceptable (e.g., bilingual: English and
native) when specified in the contract.
NOTE The use of abbreviations should be kept to a minimum.
5 Code Catalog
The following codes are recommended for codifying affected processes, causes of process deviations,
and corrections made to remedy the nonconformity. If codes are defined by a contract and/or the
originators already have codes defined that satisfy their needs, these codes shall take precedence over
the following.
NOTE The following codes represent a minimum selection of possible variances. In case of needing additional
code definitions (e.g., software, electronic, composites, structures), the tables can be enhanced by using
the existing structure.
5.1 Nonconformance Process Codes
A product nonconformance is typically associated with a process deviation. See Table 1 for a selection
processes.
5.2 Nonconformance Cause Codes
The causes of process deviations are defined in Table 2. In order to assist categorization, the list is set
up to facilitate the use of process improvement tools (e.g., cause and effect diagram). The ‘Main Term’
code can be used as the cause code, if appropriate, or further definition may be provided.
NOTE 1 One or more cause codes may be used to define the cause(s) for a product nonconformity.
NOTE 2 The allocation of a cause code could be either apparent (preliminary/initial) or final, depending on the
...
