Chapter 1 - Policy and General Information


1.1.1 This manual provides the standard, policy, procedures and guidelines for obtaining Type Design and/or Operational Approval for two-engine transport category aeroplanes to operate over a specified route containing a point farther than 60 minutes flying time at the approved one-engine-inoperative cruise speed (under standard conditions in still air) from an adequate airport regardless of terrain. The 60 minute threshold is a point beyond which the provisions of this publication apply. Previously issued approvals for ETOPS programs continue to be valid; requests for new ETOPS authorizations or changes to existing programs will be assessed under the criteria outlined in this manual. Specific criteria are included for diversion time of 75, 90, 120, or 180 minutes and beyond.


1.2.1 This manual* applies to all twin-engine aeroplanes with a MCTOW of more than 8618 kilograms (19,000 pounds) for which a Canadian type certificate has been issued authorizing the transport of 20 or more passengers (whether or not the individual aeroplane is configured for 20 or more passengers) operated by a Canadian air operator in an air transport service. ETOPS does not apply to flights conducted wholly within Canadian Domestic Airspace.

* Note: Transport Canada's Web site still publishes the previous version of TP 6327 because Chapter 2 of each publication is applicable to the aeroplane types for which an ETOPS certification application was submitted to the airworthiness authority having jurisdiction in the State of Design during the applicable dates of the TP 6327 version. The applicability of Chapter 2 is consistent with the applicability for approval of, or changes to, the type design of an aeronautical product, under Part V of the Canadian Aviation Regulations (CARs).


1.3.1 This document is enabled by Paragraph 705.26 (2)(c) of the Canadian Aviation Regulation.


1.4.1 Requests for approval for ETOPS operations with two-engine aeroplanes must be submitted, with the required supporting documentation to the applicable TCCA office at least 90 days prior to the proposed start of ETOPS operations.

1.4.2 The Aeroplane type design must meet the requirements for ETOPS design features and criteria specified in Chapter 2 (Design Features Criteria) of this manual unless another Standard is available.

Despite the above, ETOPS type design approval is not required for air operators requesting approval to conduct 75 minute operations in Benign Areas of Operations. The airframe-engine combination and the general scope of the operation will be reviewed by the POI and the PMI to determine if there are any factors that could affect the safe conduct of operations before an Operations Specification (Ops Spec) is issued.

1.4.3 In addition, for ETOPS operations other than 75 minutes Benign Area of Operation, the following criteria must be met prior to conducting ETOPS operations:

a) Satisfy the operational approval considerations (Operational Approval Criteria) specified in Chapter 3 of this manual;

c) Demonstrate that the maintenance checks, servicing, and programs called for in Chapter 4 of this manual are properly conducted;

d) Demonstrate that ETOPS flight release practices, policies, and procedures are established; and,

e) Conduct an operational validation flight, in the aeroplane or an approved simulator (as determined by Transport Canada, Civil Aviation (TCCA) on a case-by-case basis), where demonstration of the following emergency conditions must be incorporated;

i) Total loss of thrust of one engine;

ii) Total loss of normal generated electrical power;

iii) Total loss of pressurization; and

iv) Any other event or condition considered to be equivalent in operational challenge, safety management, crew workload or performance risk.

When the foregoing has been reviewed and found acceptable, a recommendation from the Principal Maintenance Inspector (PMI) and the Principal Operating Inspector (POI) will be forwarded to the to the responsible Manager, for approval and the applicant will be issued an Operations Specification to conduct ETOPS operations within specified limitations.


1.5.1 Due to the special nature of ETOPS continuous processes, procedures and training are required to be maintained once ETOPS approval is issued.

1.5.2 Subject to the Subsection 1.5.3, where an air operator ceases actual ETOPS operations for a period exceeding 13 months, application for re-instatement must be submitted in accordance with section 1.4 of this document.

1.5.3 Where an air operator cease actual ETOPS operation for a period exceeding 13 months but maintains simulated ETOPS processes, procedures and training as prescribed in this manual, the ETOPS approval may be maintained until actual ETOPS operation is resumed.

However, when actual ETOPS operation resumes following a period of actual ETOPS inactivity that exceeds 13 months, a recurrent training must be completed by each flight crew member as per the requirements of Subsection 725.124(36) of the Commercial Air Service Standards (CASS) and an ETOPS recurrent must be completed by each flight dispatcher as per the requirement of Paragraph 725.124(21)(t) of the Commercial Air Service Standards (CASS).
