PROCESS MANAGEMENT FOR AVIONICS –
MANAGEMENT PLAN –
Part 1: Preparation and maintenance of
an electronic components management plan

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62239-1 has been prepared by IEC technical committee 107:
Process management for avionics.
IEC 62239-1 cancels and replaces IEC TS 62239-1 published in 2015.
This first edition cancels and replaces the first edition of IEC TS 62239-1 published in2015.
This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) added references to SAE EIA-STD-4899, IECQ OD 3702, IECQ OD 3407-1, IEC TR
62240-2, IECQ component schemes, SAE AS6081, SAE AS6171. GEIA-STD-0005-1 GEIA
STD 0008;
IEC 62239-1:2018 © IEC 2018 – 5 –
b) replaced Annex C (which was transferred into IEC TR 62240-2) with a cross-reference
table to SAE EIASTD4899 rev C clauses/subclauses for guidance purposes only;
c) added the analysis of component technical erratum in 4.8.2;
d) updated Bibliography and reference documents.
The text of this international standard is based on the following documents:

INTRODUCTION
This document provides the structure for avionics equipment manufacturers, subcontractors,
maintenance facilities, and other aerospace component users to develop their own electronic
component management plan (ECMP), hereinafter also referred to as ‘plan’. This document
states objectives to be accomplished. The plan does not describe specific requirements and
those who prepare plans in compliance with this document will document processes that are
the most effective and efficient for them in accomplishing the objectives of this document. In
order to allow flexibility in implementing and updating the documented processes, plan owners
are encouraged to refer to their own internal process documents instead of including detailed
process documentation within their plans.
NOTE The equipment manufacturer, often called in the industry the original equipment manufacturer (OEM) is in
general considered as the plan owner.
This component management document is intended for aerospace users of electronic
components. This document is not intended for use by the manufacturers of electronic
components. Components selected and managed according to the requirements of a plan
compliant with this document may be approved by the concerned parties for the proposed
application, and for other applications with equal or less severe requirements.
Organizations that prepare such plans may prepare a single plan and use it for all relevant
products supplied by the organization or may prepare a separate plan for each relevant
product or customer.

PROCESS MANAGEMENT FOR AVIONICS –
MANAGEMENT PLAN –
Part 1: Preparation and maintenance of
an electronic components management plan

1 Scope
This part of IEC 62239 defines the requirements for developing an electronic components
management plan (ECMP) to guarantee to customers that all of the electronic components in
the equipment of the plan owner are selected and applied in controlled processes compatible
with the end application and that the technical requirements detailed in Clause 4 are
accomplished.
In general, the plan owner of a complete electronic components management plan (ECMP) is
the avionics original equipment manufacturer (OEM).
NOTE SAE EIA-STD-4899 can be used to comply with the requirements of IEC 62239-1 where applicable (see
Annex C), to enable the plan owner to harmonise its plan for both documents.
This document provides an aid in the aerospace certification process.
Although developed for the avionics industry, this process can be applied by other industrial
sectors.

4 Technical requirements
4.1 General
The plan shall document the processes used by the plan owner to accomplish the following
requirements which apply to all electronic components, including off-the-shelf components,
which are defined by the component manufacturer's data sheet, and custom components,
which are defined by the plan owner:
a) component selection;
b) component application;
c) component qualification;
d) component quality assurance;
e) component dependability;
f) component compatibility with the equipment manufacturing process;
g) component data;
h) configuration control.
The plan owner is responsible for these requirements even when subcontracting out, see
4.4.8 and 5.6.3.
Table A.1 provides a requirements matrix that may be used to document the accomplishments
of the technical requirements for IEC 62239-1.
Table D.1 provides guidelines for environmental protection techniques to be considered
during the avionics design process.
4.2 Component selection
4.2.1 General
All components shall be selected according to documented processes and satisfy the
requirements of 4.2 regardless of additional criteria such as standardization, order
of preference, etc.
Because of the highly individual nature of most plan owners’ administrative processes, no
detail is included here. Component selection can include the use of a preferred COTS
component list, provided the requirements of 4.2 are met when the components are placed
onto the standard list. Components should then be selected from the standard list for use in
specific applications. The selection process m
