1.0  INTRODUCTION

1.1  Purpose

The purpose of this Staff Instruction (SI) is to provide guidance concerning the acceptance of modifications and repairs intended for use on Russian Kamov Ka-32A11BC transport category rotorcraft, its components, and on its Klimov Scientific and Industrial Enterprise engines (model TB3-117BMA or TB3-117BMA series 02) that are designed by a party other than Kamov or Klimov.

1.2  Applicability

This document applies to all Transport Canada Civil Aviation (TCCA) employees, to individuals and organizations when they are exercising privileges granted to them under an External Ministerial Delegation of Authority. This information is also available to the aviation industry for information purposes.

3.0  BACKGROUND

  1. The introduction of the Russian Kamov Ka-32A11BC transport category rotorcraft for Canadian operation on a Certificate of Airworthiness has created a novel situation.
  2. The 1995 validation visit to Kamov Company for the type certification of the model Ka-32A11BC transport category rotorcraft was conducted using the procedures applicable for the certification of any foreign designed aircraft. While there had been a prior visit by the Aircraft Certification team to familiarize themselves with the Russian Aviation Register and their certification system in general, no activity was ever undertaken to determine the acceptability of their equipment and materials. It was considered acceptable for Canadian operation of a Restricted Category aircraft to accept the Russian equipment and materials as an integral part of the aircraft certification activity, resulting in the issuance of type certificate number H-100 and IE-35.
  3. During the U.S. assessment of the Russian aircraft certification system for a Bilateral Airworthiness Agreement (BAA), a need for evaluation of material strength properties and design values in that system became apparent. As a result, the Federal Aviation Administration (FAA) and the Russian Aviation Register engaged in the Russian-American Materials Assessment Team (RAMAT) to compare structural materials. Western materials is qualified in accordance with the statistical methods of MIL-HDBK-5J and MIL-HDBK-17F, whereas the Russian material is manufactured to a specification and then subject to several levels of quality control, depending on the specific application.
  4. The FAA concluded that the materials were adequately controlled within the Russian system, although, were not suitable for introduction into Western aeronautical products. These materials would, however, be considered acceptable for use on Russian designed products.

4.0  DESIGN CHANGE PROCEDURES

  1. Any changes to the type design of the Kamov Ka-32A11BC transport category rotorcraft shall comply with the procedural requirements of Part V of the Canadian Regulations for the approval modification and repair designs. In addition, the applicant shall consider the following limitations:

    1. The materials and equipment incorporated into the design of the Kamov Ka-32A11BC transport category rotorcraft and its Klimov Scientific and Industrial Enterprise engines (model TB3-117BMA or TB3-117BMA series 02) are acceptable for use on aircraft certified by the Russian Aviation Register.
    2. The materials and equipment incorporated into the design of the Kamov Ka-32A11BC transport category rotorcraft and its engines are NOT acceptable for use on any other Canadian registered aircraft.
    3. In accordance with normal Original Equipment Manufacturer’s acceptance procedures, design changes originated by Kamov and intended for the Kamov Ka-32A11BC transport category rotorcraft, or by Klimov intended for the Klimov Scientific and Industrial Enterprise engines (model TB3-117BMA or TB3-117BMA series 02) using Russian materials or equipment are acceptable on the basis of an approval issued by the Russian Aviation Register. Kamov has the responsibility to advise TCCA of any non-routine design changes before releasing such modifications for use on Canadian registered aircraft. The paperwork associated with all modifications and repairs, classified as routine or non-routine in nature, should clearly indicate that the Russian Aviation Register has approved them. The Russian Aviation Register system does not recognize third party design changes originating from the Commonwealth of Independent States.
    4. Design changes approved by means of a Canadian Supplement Type Certificate (STC), Limited Supplement Type Certificate (LSTC) or Repair Design Certificate (RDC) for the Kamov Ka-32A11BC transport category rotorcraft, using Russian materials or equipment, can only be approved by a regional aircraft certification office where an independent means of compliance can be used, for example static testing of a fabricated component.
  2. Where it is felt appropriate to consider an exception to the foregoing limitations, a rationale is to be documented and submitted to National Aircraft Certification for review and agreement.
