HKAR 145.50 Certification of maintenance
(See AMC 145.50)
(a)
(b)
(c)
(d)
(e)
(f)
A Certificate of Release to Service shall be issued by appropriately authorised
certifying staff on behalf of the HKAR-145 approved maintenance organisation when
it has been verified that all maintenance ordered has been properly carried out by the
HKAR-145 approved maintenance organisation in accordance with the procedures
specified in the HKAR 145.70 maintenance organisation exposition, taking into
account the availability and use of the maintenance data specified in HKAR 145.45
and that there are no non-compliances which are known that hazard seriously the
flight safety.
A Certificate of Release to Service shall be issued before flight at the completion of
any maintenance. A Certificate of Release to Service must contain basic details of
the maintenance carried out including detailed reference of the approved data used,
the date such maintenance was completed and the identity including approval
reference of the HKAR-145 approved maintenance organisation and certifying staff
issuing such a certificate.
New defects or incomplete maintenance work orders identified during the above
maintenance shall be brought to the attention of the aircraft operator for the specific
purpose of obtaining agreement to rectify such defects or completing the missing
elements of the maintenance work order. In the case where the aircraft operator
declines to have such maintenance carried out under this paragraph, paragraph (e)
below is applicable.
A Certificate of Release to Service shall be issued at the completion of any
maintenance on an aircraft component whilst off the aircraft. The Authorised
Release Certificate identified as CAD Form One in Section 4 Appendix No. 1 to
HKAR-145 constitutes the aircraft component Certificate of Release to Service.
When a HKAR-145 approved maintenance organisation maintains an aircraft
component for its own use, a CAD Form One may not be necessary depending upon
the organisation's internal release procedures defined in the maintenance organisation
exposition.
Notwithstanding paragraph (a), when the HKAR-145 approved maintenance
organisation is unable to complete all maintenance ordered, it may issue a Certificate
of Release to Service within the approved aircraft limitations. The HKAR-145
approved maintenance organisation shall enter such fact in the aircraft Certificate of
Release to Service before the issue of such certificate.
Notwithstanding paragraph (a) and HKAR 145.42, when an aircraft is grounded at a
location other than the main line station or main maintenance base due to the
non-availability of an aircraft component with the appropriate release certificate, it is
permissible to temporarily fit an aircraft component without the appropriate release
certificate for a maximum of 30 flight hours or until the aircraft first returns to the
main line station or main maintenance base, whichever is the sooner, subject to the
aircraft operator agreement and said aircraft component having a suitable release
