21.1 General
For the purpose of this Annex I (Part 21), ‘competent authority’ shall be:
(a) for organisations having their principal place of business in a Member State, the authority designated by that Member
State; or the Agency if so requested by that Member State; or
(b) for organisations having their principal place of business in a non-member State, the Agency.
SECTION A
TECHNICAL REQUIREMENTS
SUBPART A — GENERAL PROVISIONS
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 holder’s 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 Regu
lations.
(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.
21.A.3B Airworthiness directives
(a) An airworthiness directive means a document issued or adopted by the Agency which mandates actions to be
performed on an aircraft to restore an acceptable level of safety, when evidence shows that the safety level of this
aircraft may otherwise be compromised.
(b) The Agency shall issue an airworthiness directive when:
1. an unsafe condition has been determined by the Agency to exist in an aircraft, as a result of a deficiency in the
aircraft, or an engine, propeller, part or appliance installed on this aircraft; and
2. that condition is likely to exist or develop in other aircraft.
(c) When an airworthiness directive has to be issued by the agency to correct the unsafe condition referred to in point
(b), or to require the performance of an inspection, 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, shall:
1. propose the appropriate corrective action or required inspections, or both, and submit details of these proposals to
the Agency for
