5 Executive Summary New Zealand Type Acceptance has been granted to the MD Helicopters Inc. Model 600N based on validation of FAA Type Certificate number H3WE. There are no special requirements for import. The 600N is now eligible for the issue of an Airworthiness Certificate in the Standard Category in accordance with CAR , subject to any outstanding New Zealand operational requirements being met. (See Section 5 of this report for a review of compliance of the basic type design with the operating Rules.) 1. Introduction This report details the basis on which Type Acceptance Certificate No. 4/21B/7 was granted in the Standard Category in accordance with NZCAR Part 21 Subpart B. Specifically the report aims to: (a) Specify the foreign type certificate and associated airworthiness design standard used for type acceptance of the model in New Zealand; and (b) Identify any special conditions for import applicable to any model covered by the Type Acceptance Certificate; and (c) Identify any additional requirements which must be complied with prior to the issue of a NZ Airworthiness Certificate or for any subsequent operations. 2. Foreign Type Certificate Details Type Certificate: H3WE Issued by: Manufacturer: Model: Engine: MCTOW Federal Aviation Administration MD Helicopters Inc. (See TCDS Production Basis for manufacturer changes) 600N Rolls Royce 250-C47M 4100 lb. Noise Category: FAR 36, Appendix J at Amendment The certification basis of the Model 600N is FAR 27 dated October 2, 1964 through Amendment 27-30, with some deviations as noted in Section 4. This is an acceptable certification basis in accordance with NZCAR Part 21B Para 21.41, as FAR Part 27 is the basic standard for Normal Category Rotorcraft called up under Part 21 Appendix C. One Equivalent Safety Finding was granted and a special condition relating to HIRF was imposed by the FAA, because of the FADEC engine control system. There are no non-compliances and no additional special conditions have been prescribed by the Director under TAR 4/21B/7 MDHI 600N

6 The certification basis of the Rolls Royce 250-C47M is FAR Part 33, with Amendments 33-2 through 33-4, and Exemption Number 2087B from FAR This is the basic standard for aircraft engines called up under Part 21 Appendix C. 3. Type Acceptance Certificate The application for New Zealand type acceptance, dated 10 th September 2003, was from Faram Helicopters Ltd, the importer of the first-of-type example serial number RN016, registered ZK-INT. The MD600N is an eight-seat single turbine light utility helicopter. Type Acceptance Certificate No. 4/21B/7 was granted on 10 th October 2003 to the MDHI 600N based on validation of FAA Type Certificate H3WE, and includes the Rolls Royce 250C-47M turbine engine based on validation of FAA Type Certificate E1GL. There are no special requirements for import into New Zealand. The 600N is a stretched development of the Model 500N, the final evolution of the Hughes 369 Series and which first introduced the NOTAR torque-control system. (The Model 500N was previously type accepted in September See TAR 4/93.) The main changes are a 30 inch extension to the cabin to fit an extra row of seats; the NOTAR tailboom is extended 28 inches; power is increased from 425 to 600 hp with the installation of the FADEC-equipped 250C-47M engine, along with higher fuel capacity; a new transmission and drive system is fitted to support the higher loads, including a six-bladed main rotor head; longer strengthened landing skids are fitted; and maximum gross weight is increased. 4. Type Data The type data requirements of NZCAR Part 21B Para have been satisfied by supply of the following documents: (1) Type certificate: FAA Type Certificate H3WE Model 600N approved May 15, 1997 FAA Type Certificate Data Sheet H3WE at Revision 21 dated May 10, 2003 FAA TCDS E1GL at Rev. 21 dated 9 June C47M added May 14, 1997 (2) Airworthiness design requirements: Already held by the CAA. (3) Certification compliance listing: MDHS Model 600N Compliance Checklist Rev B, dated 3/1/00 MD 600N Special Condition 27-ASW-4, protection for electrical / electronic systems from High Intensity Radiated Fields (HIRF), dated January 21, 1997 Issue Paper F-1 Power on V NE Envelope Limits, dated April 22, 1997 FAR para.s (b) and specify handling conditions to be met. The 600N initially did not meet these, including pilot control feedback loads and pilot skill level needed to maintain a 30 banked turn. To meet these V NE was reduced and the MCP TOT limit reduced above 10,000 feet. Issue Paper F-2 MCP Climb Directional Stability, dated April 22, 1997 FAR requires static directional stability be positive in cruise and climb at sideslip angles up to ±10. The 600N had difficulty in complying with this at aft c.g., even at reduced MCP, and V Y was increased. TAR 4/21B/7 MDHI 600N 2

7 Issue Paper M-1 Instructions for Continued Airworthiness, dated April 15, 1997 Boeing letter Magish to Winnert (UK-CAA), Subject: Certification MD 600N: UK CRI A-01 Applicable Requirements and Depth of Investigation and CAI FAA Regression, Dated: October 6, 1998 Containing: ICPTF Justification for MDHS Model 600N Issue Paper G-1, TC Basis, dated December 26, 1996 and related revisions The 600N was accepted as a derivative of the 369/500N Series, which were certificated to CAR 6. However McDonnell Douglas Helicopter System (MDHS), as it was then known, elected to show compliance against FAR 27 Admt 30. However the FAA agreed to the following regressions: FAR (Emergency Landing Dynamic Conditions) and FAR (Flammable Fluid Fire Protection) were excluded. This was substantiated in accordance with AC20-ICPTF methodology. MDHS demonstrated energy absorbing seats could not be justified economically. This was based on an analysis of Model 369/500N data, which showed only 8% of all survivable accidents resulted in fatalities, even though the helicopter was destroyed in 31% of cases. This proved the inherent crashworthiness of the basic fuselage design. The regulatory analysis using the AC Safety/Resource Evaluation Guide showed the dynamic seating change in this case would be not effective. Service experience was also accepted for the fuel system on the basis there had never been an in-flight fire from that cause in 25 million flight hours. MDHS also added other beneficial enhancements including self-sealing valves, fuel-free vent tubes and the 50 drop test for the fuel cell. FAR at Amendment Incidental to the exclusion of FAR FAR (Self Locking Nuts) at Amendment 27-3 Accepted on the basis that relevant service experience shows the current fastener design (expanding bolts) was safe and acceptable. FAR (Seats, berths, safety belts and harnesses) at Amendment Shoulder harnesses are fitted as standard. Otherwise incidental to the exclusion of FAR FAR (Static Pressure Systems) at Amendment Accepted as identical to the 500N. Issue Paper P-3, Engine Gas Generator Speed Instrument Display (ESF) The FAA granted an Equivalent Safety Decision against FAR (b) for the N 1 gauge. The 600N gauge only displays the RPM in digits with abnormal values shown by a single red light with no trend indication. This literal non-compliance was accepted because N1 is only a third (back-up) gauge for engine power level and abnormal conditions are adequately indicated by the red LED.

(4) Flight manual: FAA-Approved Rotorcraft Flight Manual for the MD 600N Doc. CSP-600RFM-1 Reissue #1, Rev. 7 CAA Accepted as AIR 2838 Note: The FM has an unusual presentation of performance in three sections. (See Discussion Paper: MD 600N Certification Basis and the Rotorcraft Flight Manual, Dated 11 Feb 2000) MD was only able to show compliance with the FAR 27 H-V requirement at 7000 ft Density Altitude (DA) up to 3850 lb. Above this weight the FAA accepted compliance with the more restrictive FAR 29 case where the manufacturer can demonstrate all critical combinations of internal weight and DA, on the basis of equivalent safety. However the FAA would not allow RFM charts that combined FAR 27 and FAR 29 rules. Therefore there are two separate FAA approved performance sections in the Flight Manual, and another MD-approved section which combines them, for ease of reading. 3 TAR 4/21B/7 MDHI 600N
