From: Transport Canada

NCR-026-2017

Pursuant to subsection 5.9(2) of the Aeronautics Act, and after taking into account that the exemption is in the public interest and is not likely to adversely affect aviation safety or security, I hereby exempt persons who perform maintenance on General Electric (GE) turbofan engine models CF34-SC, CF34-8E and CF34-10E installed or intended to be installed on Canadian aircraft (“maintenance persons” hereinafter) from compliance with the requirements set out in paragraph 571.08(1)(b) of the Canadian Aviation Regulations (CARs), subject to the conditions below.

This exemption applies:

  • a) Only with respect to the installation of GE CF34-8C, CF34-8E and CF34-10E engine fan blades that have undergone maintenance performed and certified by IHI Corporation (IHI), of 229 Tonogaya, Mizuho-Machi, Nishitama-Gun, Tokyo 190-1297, Japan (hereinafter referred to as “IHI”).

Section 571.08 of the CARs states:

  • (1) No person shall install a used part on an aeronautical product, other than aircraft that are operated under a special certificate of airworthiness in the owner-maintenance or amateur-built classification, unless the part meets the standards of airworthiness that are applicable to the installation of used parts and are set out in Chapter 571 of the Airworthiness Manual and
    • (a) is an airworthy part that has been removed from an aircraft for immediate installation on another aircraft;
    • (b) is an airworthy part that has undergone maintenance for which a maintenance release has been signed pursuant to paragraph 571.11(2)(c); or
    • (c) has been inspected and tested to ensure that the part conforms to its type design and is in a safe condition, and a maintenance release has been signed to that effect.
  • (2) If, under the terms of a loan agreement or an air operator parts pooling agreement, a used part has been obtained from a source not subject to these Regulations, no person shall permit the part to remain in service for longer than 90 days unless specifically authorized by the Minister on receipt of documentation demonstrating that the part conforms to the applicable type design.

Purpose

The purpose of this exemption is to authorize persons who perform maintenance on GE turbofan engine models CF34-8C, CP34-8E and CF34-10E, installed or intended to be installed on Canadian aircraft, to install specified part number fan blades that have undergone maintenance and which are accompanied by a maintenance release contained in an Authorized Release Certificate issued by IHI, despite the fact IHI does not hold an approved maintenance organization (AMO) certificate issued by the Minister pursuant to section 573.02 of the CARs.

Application

This exemption shall apply:

  • a) Only with respect to the installation of GE CF34-8C, CF34-8E and CF34-10E engine fan blades that have undergone maintenance performed and certified by IHI;
  • b) Only to persons who perform maintenance on GE turbofan engine models CF34-8C, CF34-8E and CF34-10E, installed on Canadian registered aircraft; and
  • c) Only to repairs conducted by IHI to the specific fan blade part numbers that are listed herein only and, for which IHI is the sole source of repairs authorised by GE.

The specific fan blade part numbers covered by this exemption are as follows:

  • i) part numbers 4114T15P02 and 4114T31G01 for the CF34-8C and CF34-8E turbofan engines models (4114T31G01 was introduced by Service Bulletin (SB) 72-0225 for CF34-8C and SB 72-0l15 for CF34-8E); and
  • ii) part number 2225M27P02 for the CF34-10E turbofan engine model.

This exemption ceases to apply to the person who breaches a condition of the exemption.

The exemption is subject to the following conditions:

  1. Maintenance persons shall validate that the repair data used by IHI are specified in the most recent version of the applicable General Electric Instructions for Continued Airworthiness (ICAs); and more specifically
