AMC1 21.A.263(c)(6) Privileges

ED Decision 2021/001/R

PROCEDURE FOR THE APPROVAL OF THE CONDITIONS
FOR THE ISSUE OF A PERMIT TO FLY (PtF)

1.       INTENT

—
This AMC provides the means to
develop a procedure to determine that an aircraft can fly, under the
appropriate restrictions compensating for non-compliance with the
certification specifications applicable to the specific aircraft category.

—
Each DOA applicant or DOA
holder should develop its own internal procedure following this AMC, in order
to obtain the privilege to make this determination and approve the associated
conditions without EASA’s involvement, under point [21.A.263](#_DxCrossRefBm1649096918)(c)(6). When the privilege does
not apply, the DOA applicant or the DOA holder will prepare all the necessary
data required for the determination in accordance with the same procedure
required for the privilege, and will apply for EASA’s approval.

—
The establishment of flight
conditions may include conditions related to engines/propellers without a type
certificate or with unapproved changes that are fitted to the aircraft, for
which a permit to fly (PtF) is requested. These conditions (i.e. the installation,
operating limitations, maintenance conditions or limitations) should be
defined by the organisation responsible for the design of the engine/propeller
and provided to the organisation responsible for the design of the aircraft.

—
These conditions should be
established and substantiated under an arrangement between the organisation
responsible for the design of the aircraft and the organisation responsible
for the design of the engine/propeller. However, the establishment and substantiation
of the flight conditions for the aircraft, including its engine(s), is
ultimately the responsibility of the organisation responsible for the design
of the aircraft.

2.       PROCEDURE
FOR THE APPROVAL OF THE CONDITIONS FOR THE ISSUE OF A PERMIT TO FLY (PtF)

2.1     Content

The procedure should address the following
points:

—
the decision to exercise the
privilege;

—
management of the aircraft
configuration;

—
determination of the
conditions that should be complied with to safely perform a flight;

—
documentation of
substantiations of flight conditions;

—
approval under the DOA
privilege, when applicable; and

—
the authorised signatories.

2.2     Decision
to exercise the privilege of point [21.A.263](#_DxCrossRefBm1649096918)(c)(6)

The procedure should include a decision to
determine the flights for which the privilege of point [21.A.263](#_DxCrossRefBm1649096918)(c)(6) will be exercised.

2.3     Management
of the aircraft configuration

The procedure should indicate:

—
how the aircraft, for which an
application for a permit to fly is made, is identified; and

—
how changes to the aircraft
will be managed.

2.4     Determination
of the conditions that should be complied with to safely perform a flight

The procedure should describe the process
used by the DOA holder to justify that the aircraft can perform the intended
flight(s) safely. This process should include:

—
with reference to point [21.A.701](#_DxCrossRefBm1649097379)(a), identification of the
applicable airworthiness requirements which the aircraft does not meet, or has
not been shown to meet, if applicable, and of the purpose of the flight(s);
for flight conditions raised to cover unapproved changes, the identification
of the applicable airworthiness requirements which the aircraft does not meet,
or has not been shown to meet, can be fulfilled by referring to the
certification programme of the unapproved changes;

—
the analysis, calculations,
tests or other means used to determine under which conditions or restrictions
the aircraft can safely perform a flight (the flights);

—
the establishment of specific
maintenance instructions and conditions to perform these instructions;

—
an independent technical
verification of the analysis, calculations, tests or other means used to
determine under which conditions or restrictions the aircraft can perform the
intended flight(s) safely;

—
a statement by the office of
airworthiness (or equivalent), that the determination has been made in
accordance with the related procedure and that the aircraft has no features
and characteristics that render it unsafe for the intended operation(s) under the
identified conditions and restrictions; and

—
approval by an authorised
signatory.

2.5     Documentation
of flight conditions substantiations

1.       The
analysis, calculations, tests~~,~~ or other means used to determine under
which conditions or restrictions the aircraft can safely perform a flight (or
the flights) should be compiled in compliance documents. These documents
should be signed by the author and by the person performing the independent
technical verification.

2.       Each
compliance document should have a number and an issue date. The various issues
of a document should be controlled.

3.       The
data submitted and approved by the TC holder can be used as substantiations.
In that case, the independent technical verification referred to in 2.4 is not
required.

2.6     Approval
under the DOA privilege

2.6.1  Initial
approval

The procedure should include the following
EASA Form 18A (as an alternative, the DOA holder should provide an equivalent
template containing the same level of information) to
support the approval under the DOA privilege:
