43.101 Persons to issue a release to service
A person shall not certify an aircraft or aircraft component for release to service after maintenance unless he:
(a) is authorised by the Governor in a particular case in relation to the specific aircraft maintenance task; and
(1) has attained a level of initial/continuation training and evidence of recent experience and competence assessment acceptable to the Governor; and
(2) holds a current valid licence and type specific training acceptable to a ICAO contracting State in accordance with ICAO Annex 1; or
(i) where an aircraft is grounded or operating away from a supported location other than the main base where no appropriate certifying staff are available, holds a current valid licence issued by an ICAO contracting State in accordance with ICAO Annex 1 on an aircraft type of similar technology, construction and systems; or
(ii) in the case of aircraft operating away from a supported location, holds a flight crew licence with sufficient practical training acceptable to the Governor, to ensure that the flight crew member can accomplish the specified task to the required standard; or
(b) is authorised by the Governor under the provisions of OTAR Part 66.
(c) holds an authorisation issued by a maintenance organisation appropriately approved under OTAR Part 145 and is certifying within the scope of that approval; or
(d) in the case of flight crew, holds an authorisation issued by a maintenance organisation appropriately approved under an OTAR Part 145 to carry out the actions associated with a repetitive pre-flight airworthiness directive.
(a) A person authorised by the Governor under paragraph 43.101 shall not certify an aircraft for release to service after maintenance unless that maintenance has been performed in accordance with this OTAR Part and, in respect of that maintenance, the aircraft is fit for release to service.
(b) An OTAR Part 145 approved maintenance organisation shall not certify an aircraft for release to service after the embodiment of a major design change or a major repair unless that design change or repair has been approved in accordance with OTAR Part 21 Subpart C.
(c) Where the acceptable technical data for a design change or repair to an aircraft or component includes changes to the aircraft flight manual, the OTAR Part 145 approved maintenance organisation shall not certify the release to service until these changes have been incorporated into the applicable flight manual.
(d) Each person issuing a Release to Service under an authorisation granted by the Governor as specified in paragraph 43.101 shall after performing maintenance on an aircraft:
(1) ensure maintenance is only conducted within the scope of the authorisation granted under paragraph 43.101 and any limitations identified in the approved maintenance programme; and
(2) be familiar with the maintenance actions required for the continued airworthiness of that aircraft or component; and
(3) use adequate environmentally protected housing, lighting, access equipment and facilities for the necessary disassembly, proper inspection, and reassembly of the aircraft or component; and
(4) perform the maintenance in accordance with the manufacturer’s instructions using methods, techniques, and practices that:
(i) are prescribed in the current manufacturer's maintenance manual or Instructions for Continued Airworthiness; or
(ii) are acceptable to the Governor; and
(5) use materials, parts, and appliances approved in accordance with OTAR Part 21 Subpart K; and
(6) use the tools, equipment, and test apparatus necessary to ensure completion of the work in accordance with paragraph 43.103(d)(3); and
(7) ensure that any special tools or test equipment recommended by the manufacturer are used as specified and have been tested and calibrated to standards accepted by an NAA identified in OTAR Part 21.25(a)(1); and
(8) perform the maintenance taking into consideration human factors so as to ensure that the aircraft or component meets all applicable airworthiness requirements.
43.105 Certificate of Release to Service
Each person authorised to certify an aircraft or component for release to service after maintenance shall:
(a) enter in the log book or other record required by paragraph 43.57(b)(1) a statement of release to service that states that:
‘’The work recorded has been carried out in accordance with the Air Navigation (Overseas Territories) Order as amended and in respect of that work the aircraft or component is fit for release to service”.
Note: The Governor may approve a different release statement that recognises the maintenance standards and approvals of an NAA identified in OTAR Part 21.25(a)(1) provided that the legal intent of the statement above is maintained and the applicable CRS statement is set out in the OTAR Part 145 MOE Supplement.
(b) in all cases enter beside the statement of release to service:
(1) their signature; and
(2) their OTAR Part 66, licence or validation number or pilot’s licence number and where applicable the Governor’s authorisation reference; or,
(3) AMO approval and authorisation number; and
(4) the date of entry.
43.107 Inoperative equipment
Each person authorised to certify an aircraft for release to service that includes equipment permitted to be inoperative in accordance with the Order and provided for in an approved MEL, CDL or as otherwise approved by the Governor shall:
(a) provide the owner or operator with a list of the inoperative equipment including details of any associated aircraft performance limitations; and
(b) place a placard on each inoperative instrument and cockpit control for each item of inoperative equipment, marking each item inoperative; and
(c) make reference to the approved data permitting inoperative equipment in the aircraft technical log book; and
(d) record limitations for the rectification interval.
43.109 Defects
(a) Details of any known defect shall be recorded in the appropriate aircraft technical log book referred to in OTAR Part 39.79 or appropriate aircraft record and be supplied to the owner or operator of the aircraft.
(b) Any defect that materially affects the performance of a special operational approval or system reliability monitored by a reliability centred aircraft maintenance programme shall be rectified in manner consistent with an established programme acceptable to the Governor.
(c) All defects shall be rectified and released to service in accordance with this OTAR Part.
43.111 Independent inspection
(a) A person shall not certify an aircraft or component for release to service after the initial assembly, subsequent disturbance or adjustment of:
(1) an engine control system; or
(2) a flight control system; or
(3) a vital point; or
(4) any task identified in the aircraft maintenance programme requiring such inspections unless an independent maintenance inspection has been performed.
(b) The independent maintenance inspection required by paragraph 43.111(a) shall include:
(1) an inspection first made by an authorised person signing the maintenance release who assumes full responsibility for the satisfactory completion of the work; and
(2) a subsequent inspection by a second, independent, competent person who attests to the satisfactory completion of the work recorded and that no deficiencies have been found.
Note: The second independent competent person is not issuing a maintenance release and therefore is not required to hold certification privileges, but shall be suitably qualified to carry out the inspection.
(c) When work is being done under the control of an approved maintenance organisation, that organisation shall have procedures to demonstrate that the signatories have been trained and have gained experience on the specific control systems being inspected. It is not acceptable for the certifying staff signing the release to show the person performing the independent inspection how to perform the inspection at the time the work is completed.
