Issue and renewal of certificates of airworthiness16
1
Subject to paragraph (2), the Department must issue for an aircraft registered in the Isle of Man a certificate of airworthiness if it is satisfied that the aircraft is fit to fly having regard to—
a
the design, construction, workmanship and materials of the aircraft (including in particular any engines fitted in the aircraft), and of any equipment carried in the aircraft that it considers necessary for the airworthiness of the aircraft; and
b
the results of flying trials and such other tests of the aircraft as it may require.
2
If the Department has issued a certificate of airworthiness for an aircraft that, in its opinion, is a prototype aircraft or a modification of a prototype aircraft, it may dispense with flying trials in the case of any other aircraft if it is satisfied that the other aircraft conforms to such prototype or modification.
3
A certificate of airworthiness must —
a
specify the category “Private”; and
b
be issued subject to the condition that the aircraft may not be flown except for the purposes (which may not include commercial air transport or aerial work) specified in the certificate.
4
The Department may issue a certificate of airworthiness subject to such other conditions relating to the airworthiness of the aircraft as it thinks fit.
5
The Department may issue a certificate of validation.
6
Nothing in this Order obliges the Department to accept an application for the issue of a certificate of airworthiness or certificate of validation or for the variation or renewal of such a certificate if the application is not supported by a report from a person approved under article 158 as the Department may specify, either generally or in a particular case or class of case.
7
In this article, a certificate of validation means a certificate rendering valid for the purposes of this Order a certificate of airworthiness issued for an aircraft registered elsewhere than in the Isle of Man under the law of a country other than the Isle of Man.
Certificate of airworthiness ceasing to be in force and issue of airworthiness directives17
1
Subject to paragraph (3), a certificate of airworthiness or a certificate of validation issued for an aircraft registered in the Isle of Man ceases to be in force if—
a
the aircraft or a part of it or such of its equipment as is necessary for its airworthiness has been overhauled, repaired, replaced, modified or maintained;
b
maintenance or an inspection of the aircraft or of equipment necessary for its airworthiness is required by a maintenance programme approved by the Department for the aircraft under article 22;

maintenance of the aircraft or of equipment necessary for its airworthiness has been made mandatory by a directive issued by the Department;
d
an inspection for the purpose of ascertaining whether the aircraft remains airworthy has been made mandatory by a directive issued by the Department; or
e
any modification of the aircraft or of any equipment is necessary for its airworthiness has been made mandatory by a directive issued by the Department for the purpose of ensuring that the aircraft remains airworthy.
2
A certificate of airworthiness or a certificate of validation that has ceased to be in force under paragraph (1) becomes valid again on the issue of a certificate of release to service under this Order relating to the overhaul, repair, replacement, modification, maintenance or inspection.
3
4
In this article, a certificate of validation has the same meaning as in article 16(7).
Issue of national permits to fly18
1
Subject to paragraph (2), the Department must issue for an aircraft registered in the Isle of Man a national permit to fly if it is satisfied that the aircraft is fit to fly having regard to the airworthiness of the aircraft and the conditions to be attached to the permit.
2
The Department must refuse to issue a national permit to fly for an aircraft registered in the Isle of Man if it appears to the Department that the aircraft is eligible for, and ought to fly under and in accordance with, a certificate of airworthiness.
3
The Department may issue a national permit to fly subject to such conditions relating to the airworthiness, operation or maintenance of the aircraft as it thinks fit.
4
Nothing in this Order requires the Department to accept an application for the issue, variation or renewal of a national permit to fly if the application is not supported by a report from a person approved under article 158 as the Department may specify, either generally or in a particular case or class of cases.
National permits to fly ceasing to be in force and issue of airworthiness directives for permit aircraft19
1
A national permit to fly ceases to be in force if—
a
the Department has issued a directive that requires—
i
an inspection to be carried out for the purpose of ascertaining whether the aircraft remains airworthy; or
ii
modification or maintenance of the aircraft or any of its equipment necessary for its airworthiness for the purpose of ensuring that the aircraft remains airworthy; or
b
completion of an inspection, modification or maintenance of the aircraft is required as a condition of the permit to fly.
2
A national permit to fly that has ceased to be in force under paragraph (1) comes into force again as soon as—
a
any such inspection, modification or maintenance has been satisfactorily completed; and
b
in the case of an inspection, any consequential repair, replacement or modification has been satisfactorily carried out.
3
A national permit to fly ceases to be in force—
a
if any condition (other than a condition of the permit requiring an inspection, modification or maintenance) is not complied with;
b
if the aircraft, engines or propellers, or such of its equipment as is necessary for its airworthiness are modified or repaired, unless the repair or modification has been approved by the Department or by a person approved by the Department for that purpose.
4
A national permit to fly is not in force unless the permit includes a current certificate of validity issued by the Department or by a person approved by the Department for that purpose.
5
In this article a certificate of validity means a certificate that certifies that a national permit to fly remains valid for the period specified in the certificate and a certificate of validity is current during that period.
Limitations of national permits to fly20

An aircraft registered in the Isle of Man for which a certificate of airworthiness is in force must not fly unless the aircraft (including its engines), together with its equipment and radio station, is maintained in accordance with a maintenance programme approved by the Department for that aircraft.
2
The design and application of the maintenance programme must observe Human Factors principles as specified in any guidance material published by the Department.
Technical log23
1
This article applies to each aircraft registered in the Isle of Man for which a certificate of airworthiness is in force and which is used for international air navigation.
2
A technical log must be kept for every aircraft to which this article applies.
3
In the case of an aircraft that has a maximum total mass authorised of 2730kg or less, a record approved by the Department (in this article called “an approved record”) may be kept instead of a technical log.
4
Subject to paragraph (5), at the end of every flight the commander must enter in the technical log—
a
the times when the aircraft took off and landed,
b
information about any defect that is known to him and that affects the airworthiness or safe operation of the aircraft, or if no such defect is known to him, an entry to that effect, and
c
such other information about the airworthiness or operation of the aircraft as the Department may require,
and must sign and date each entry.
5
Subject to paragraph (6), if there are two or more consecutive flights, each of which begins and ends—
a
within the same period of 24 hours,
b
at the same aerodrome, and
c
with the same person as commander of the aircraft,
the commander may make the entries specified in paragraph (3) at the end of the last of such consecutive flights.
6
Paragraph (5) does not apply if the commander becomes aware of a defect during an earlier flight.
7
When a defect entered in a technical log or approved record is rectified the person issuing a certificate of release to service issued under this Order or under Part 145 in respect of the defect must enter the certificate in the technical log in such a position as to be readily identifiable with the defect to which it relates.
8
9
In the case of an aeroplane that has a maximum total mass authorised of 2730 kg or less, or a helicopter, if it is not reasonably practicable for the copy of the technical log to be kept on the ground it may be carried in the aeroplane or helicopter, provided that it is removed and kept on the ground as soon as reasonably practicable.
10
Subject to article 90, a technical log required by this article must be preserved by the operator of the aircraft to which it relates for at least two years after the aircraft has been destroyed or has been permanently withdrawn from use, or for such shorter period as the Department may permit in a particular case.
