Air Service Certificate S. 37 : The Air Service Certificate system, involving a great measure of detailed supervision by the Director of Civil Aviation over the management and organisation of a national operating agency, according to a code of standards which is largely unwritten, is unnecessary and inappropriate. It should not be applied to the national operating agencies, the boards of which are directly responsible to Government for the efficiency with which they carry out their mandate, while they are responsible also for compliance with the coded law. (Paragraphs 121-130.) S. 38: The Air Service Certificate system may usefully be applied to commercial operators of scheduled air services, but it is unnecessary in the case of non-scheduled air transport operators. (Paragraphs 131-132.) Airworthiness of aircraft S. 39: There is no need for a full code of New Zealand civil airworthiness requirements. The airworthiness requirements of the countries of origin of the aircraft must inevitably be accepted, with such limited modifications as may have been found necessary in New Zealand. It would not be worth while or even practicable to establish the organisation required for an occasional New Zealand designed aircraft. (Paragraphs 134-138 ; 143.) S. 40: Proposed aircraft modifications arising out of New Zealand operations should be submitted for approval after full investigation by the operator, who should employ qualified aeronautical engineers for this purpose. (Paragraphs 139-142.) 5. 41: Since the major functions of the Air Registration Board in the United Kingdom do not arise in New Zealand, there is no need for a similar body in this country. (Paragraph 145.) Type record and import control S. 42: There has been misconception regarding the content of the " type record " of an aircraft and the stage at which it is available. The type record contains the evidence on which a certificate of airworthiness is issued, and is not available until the certificate of airworthiness for the prototype has been issued. It is required for the purpose of approval of modifications. (Paragraphs 146-150 ; 157.) 5. 43: The " aeroplane flight manual," not the type record, contains a statement of the verified performance of the aircraft. The flight manual is a necessity for the proper operation of the aircraft. It is not available until the certificate of airworthiness for the prototype aeroplane is issued. (Paragraphs 151-155 ; 158.) S. 44: Many new aeroplanes are ordered before construction and testing of the prototype, and therefore before the type record and flight manual are available. While the supply of these documents may be made a condition of purchase, they may not be available to determine whether the purchase should be made. (Paragraphs 156-161.)
