ML.A.903
Airworthiness review process

Regulation
(EU) 2019/1383

(a)     To satisfy the requirement for the
airworthiness review of an aircraft referred to in point [ML.A.901](#_DxCrossRefBm1924813374),
the airworthiness review staff shall perform a documented review of the
aircraft records to verify that:

(1)     airframe, engine and propeller flying
hours and associated flight cycles have been properly recorded;

(2)     the flight manual is applicable to the
aircraft configuration and reflects the latest revision status;

(3)     all the maintenance due on the aircraft
according to the AMP has been carried out;

(4)     all known defects have been corrected or
deferred in a controlled manner;

(5)     all applicable ADs have been applied and
properly registered;

(6)     all modifications and repairs made to the
aircraft have been registered and are in compliance with Annex I (Part-21) to Regulation (EU) No
748/2012;

(7)     all service-life-limited components
installed on the aircraft are properly identified, registered and have not
exceeded their approved service life limit;

(8)     all
maintenance has been certified in accordance with this Annex;

(9)     if required, the current mass-and-balance
statement reflects the configuration of the aircraft and is valid;

(10)    the aircraft complies with the latest
revision of its type design approved by the Agency;

(11)    if required, the aircraft holds a noise
certificate corresponding to the current configuration of the aircraft in
compliance with Subpart I of Annex I (Part-21) to Regulation (EU) No 748/2012.

(b)     The airworthiness review staff referred to
in point (a) shall carry out a physical survey of the aircraft. For this
survey, airworthiness review staff not appropriately qualified under Annex III (Part-66) shall be assisted by
such qualified personnel.

(1)     all required markings and placards are
properly installed;

(2)     the aircraft complies with its approved
flight manual;

(3)     the aircraft configuration complies with
the approved documentation;

(4)     no evident defect can be found that has
not been addressed according to point [ML.A.403](#_DxCrossRefBm1924813416);

(5)     no inconsistencies can be found between
the aircraft and the documented review of records as referred to in point (a).

(d)     By derogation from point [ML.A.901(a)](#_DxCrossRefBm1924813374), the airworthiness review may
be anticipated for a maximum period of 90 days, without loss of
continuity of the airworthiness review pattern, so as to allow the physical
review to take place during a maintenance check.

(e)     The ARC (EASA Form 15c) set out to in
Appendix IV shall only be issued:

(1)     by appropriately authorised airworthiness
review staff;

(2)     when the airworthiness review has been
completely carried out, all findings have been closed;

(3)     when any discrepancy found in the AMP in
accordance with point (h) has been satisfactorily addressed.

(f)      A copy of any ARC issued or extended for
an aircraft shall be sent to the Member State of registry of that aircraft
within 10 days.

(g)     Airworthiness review tasks shall not be subcontracted.

(h)     The effectiveness of the AMP may be
reviewed in conjunction with the airworthiness review in accordance with point
(c)(9) of point [ML.A.302](#_DxCrossRefBm1924813372). This review shall be completed by the person
who performed the airworthiness review. If the review shows deficiencies of
the aircraft linked with deficiencies in the content of the AMP, the AMP shall
be amended accordingly. The person performing the review shall inform the
competent authority of the Member State of registry if he does not agree with
the measures amending the AMP taken by the owner, CAMO or CAO. In such case
the competent authority shall decide which amendments to the AMP are
necessary, raising the corresponding findings defined in point [ML.B.903](#_DxCrossRefBm1924813445) and,
if necessary, reacting in accordance with point [ML.B.304](#_DxCrossRefBm1924813394).
