21.A.1 Scope This Section establishes general provisions governing the rights and obligations of the applicant for, and
holder of, any certificate issued or to be issued in accordance with this Section.
21.A.2 Undertaking by another person than the applicant for, or holder of, a certificate The actions and obligations required to be undertaken by the holder of, or applicant for, a certificate for a
product, part or appliance under this Section may be undertaken on its behalf by any other natural or legal
person, provided the holder of, or applicant for, that certificate can show that it has made an agreement
with the other person such as to ensure that the holders obligations are and will be properly discharged.
21.A.3A Failures, malfunctions and defects (a) System for Collection, Investigation and Analysis of Data
The holder of a type-certificate, restricted type-certificate, supplemental type-certificate, European
Technical Standard Order (ETSO) authorisation, major repair design approval or any other relevant
approval deemed to have been issued under this Regulation shall have a system for collecting,
investigating and analysing reports of and information related to failures, malfunctions, defects or other
occurrences which cause or might cause adverse effects on the continuing airworthiness of the product,
part or appliance covered by the type-certificate, restricted type-certificate, supplemental type-certificate,
ETSO authorisation, major repair design approval or any other relevant approval deemed to have been
issued under this Regulation. Information about this system shall be made available to all known operators
of the product, part or appliance and, on request, to any person authorised under other associated
implementing Regulations.
(b) Reporting to the Agency
1. The holder of a type-certificate, restricted type-certificate, supplemental type-certificate, ETSO
authorisation, major repair design approval or any other relevant approval deemed to have been issued
under this Regulation shall report to the Agency any failure, malfunction, defect or other occurrence of
-

which it is aware related to a product, part, or appliance covered by the type-certificate, restricted type-
certificate, supplemental type-certificate, ETSO authorisation, major repair design approval or any other
relevant approval deemed to have been issued under this Regulation, and which has resulted in or may
result in an unsafe condition.
2. These reports shall be made in a form and manner established by the Agency, as soon as practicable
and in any case dispatched not later than 72 hours after the identification of the possible unsafe condition,
unless exceptional circumstances prevent this.
(c) Investigation of Reported Occurrences
1. When an occurrence reported under point (b), or under points 21.A.129(f)(2) or 21.A.165(f)(2) results
from a deficiency in the design, or a manufacturing deficiency, the holder of the type-certificate, restricted
type-certificate, supplemental type-certificate, major repair design approval, ETSO authorisation, or any
other relevant approval deemed to have been issued under this Regulation, or the manufacturer as
appropriate, shall investigate the reason for the deficiency and report to the Agency the results of its
investigation and any action it is taking or proposes to take to correct that deficiency.
2. If the Agency finds that an action is required to correct the deficiency, the holder of the type-certificate,
restricted type-certificate, supplemental type-certificate, major repair design approval, ETSO authorisation,
or any other relevant approval deemed to have been issued under this Regulation, or the manufacturer as
appropriate, shall submit the relevant data to the Agency.
AMC No 1 to 21.A.3A(a) Collection, investigation and analysis of data related to Flammability Reduction Means (FRM) reliability Holders of a type-certificate, restricted type-certificate, supplemental type-certificate or any other
relevant approval deemed to have been issued under Part 21 and which have included a FRM in
their design should assess on an on-going basis the effects of aeroplane component failures on
FRM reliability. This should be part of the system for collection, investigation and analysis of data
required by 21.A.3 (a). The applicant/holder should do the following:
(a) Demonstrate effective means to ensure collection of FRM reliability data. The means
should provide data affecting FRM reliability, such as component failures.
(b) Unless alternative reporting procedures are approved by the Agency, provide a report to
the Agency every six months for the first five years after service introduction. After that
period, continued reporting every six months may be replaced with other reliability tracking
methods found acceptable to the Agency or eliminated if it is established that the reliability
of the FRM meets, and will continue to meet, the exposure specifications of paragraph
M25.1 of Appendix M to CS-25.
(c) Develop service instructions or revise the applicable aeroplane manual, according to a
schedule approved by the Agency, to correct any failures of the FRM that occur in service
that could increase any fuel tanks Fleet Average Flammability Exposure to more than that
specified by paragraph M25.1 of Appendix M to CS-25.

AMC No 2 to 21.A.3A(a) Collection, investigation and analysis of data related to ETOPS significant occurrences (1) Holders of a type-certificate, restricted type-certificate, supplemental type-certificate or
any other relevant approval deemed to have been issued under Part 21 and which
includes extended range operation with two-engined aeroplane (ETOPS) capability should
implement a specific tracking, reporting and resolution system for ETOPS significant
occurrences, suitable to ensure the initial and continued fleet compliance with the
applicable ETOPS reliability objectives. This system should be part of the system for
collection, investigation and analysis of data required by 21.A.3A(a).
Appropriate coordination should exist between engine TC holder, propeller TC holder and
APU ETSO authorisation holder with the aircraft TC holder to ensure compliance
with the ETOPS reliability objectives.
(2) For tracking, reporting and resolution of ETOPS significant occurrences refer to EASA the
latest edition of AMC 20-6 (see AMC-20 document).
GM 21.A.3A(a) The system for collection, investigation and analysis of data In the context of this requirement the word Collection means the setting up of systems and
procedures which will enable relevant malfunctions, fa
