Appendix 3 APPENDIX 3. ETOPS APPROVAL METHODS The two different approval methods available for a certificate holder’s use are described in this appendix.
1. In-Service Experience Method (Two-Engine ETOPS for up to 180-Minute ETOPS).
a. General.
(1) An in-service experience program is one way of gaining ETOPS operational approval. As a prerequisite to obtaining any operational approval, the certificate holder should show that an acceptable level of propulsion system reliability has been achieved in service by the world fleet for that particular airplane-engine combination. The candidate certificate holder also should obtain sufficient maintenance and operation familiarity with the particular airplane-engine combination. Each certificate holder requesting approval to conduct ETOPS by the in-service method should have operational experience appropriate to the operation proposed.
(2) This appendix contains guidelines for requisite in-service experience. These guidelines may be reduced or increased following review and concurrence on a case-by-case basis by the Director, Flight Standards Service. Any reduction or increase in in-service experience guidelines will be based on an evaluation of the certificate holder’s ability and competence to achieve the necessary reliability for the particular airplane-engine combination in ETOPS. For example, a reduction in in-service experience may be considered for a certificate holder who can show extensive in-service experience with a related engine on another airplane that has achieved acceptable reliability. In contrast, an increase in in-service experience may be considered for those cases where heavy maintenance has yet to occur and/or abnormally low number of takeoffs has occurred.
b. Specific Approvals.
(1) 75- and 90-Minute Operation. Consideration may be given to the approval of 75-minute and 90-minute ETOPS for certificate holders with minimal or no in-service experience with the airplane-engine combination. This determination considers such factors as the proposed area of operations, the certificate holder’s demonstrated ability to successfully introduce airplanes into operations, and the quality of the proposed maintenance and operations programs.
(2) 120-Minute Operation. Each certificate holder requesting approval to conduct ETOPS with a maximum diversion time (in still air) of 120 minutes should have 12 consecutive months of operational in-service experience with the specified airplane-engine combination. Inservice experience guidelines may be increased or decreased by the Director, Flight Standards Service.
Appendix 3
(3) 180-Minute Operation.
(a) Each certificate holder requesting approval to conduct ETOPS with a maximum diversion time (in still air) of 180 minutes should have previously gained 12-consecutive months of operational in-service experience with the specified airplane-engine combination in conducting 120-minute ETOPS. In-service experience guidelines may be reduced or increased by the Director, Flight Standards Service. Likewise, the substitution of in-service experience, which is equivalent to the actual conduct of 120-minute ETOPS operations, also will be established by the Director, Flight Standards Service, on a case-by-case basis.
(b) Before approval, the certificate holder’s capability to conduct operations and implement effective ETOPS programs in accordance with the criteria detailed in this AC will be examined. Only certificate holders who have demonstrated capability to successfully conduct a 120-minute program will be considered for approval beyond 120-minutes. Approval will be given on a case-by-case basis for an increase to their area of operation beyond 120-minutes. The dispatch limitation will be a maximum diversion time of 180 minutes to an ETOPS alternate at an approved one-engine inoperative speed (under standard conditions in still air).
c. Requesting Approval. A certificate holder requesting approval under Title 14 of the Code of Federal Regulations (14 CFR) part 121, § 121.161 for ETOPS under this method should submit the request with the required supporting data to its CHDO at least 60 days before the proposed start of ETOPS operation with the specific airplane-engine combination. In considering an application from a certificate holder to conduct ETOPS, the CHDO should assess the certificate holder’s overall safety record, past performance, flight crewmember training, and maintenance programs. The data provided with the request should substantiate the certificate holder’s ability and competence to safely conduct and support these operations and should include the means used to satisfy the considerations outlined in this paragraph.
2. Accelerated ETOPS Method (Up to 180-Minute ETOPS for Two-Engine Airplanes and for all ETOPS for Passenger-Carrying Airplanes With More Than Two Engines). This section describes the means by which a certificate holder may initiate ETOPS operations when the certificate holder establishes the processes necessary for successful and reliable ETOPS operations and proves to the FAA that such processes can be successfully applied throughout the applicant’s ETOPS operations. This may be achieved by thorough documentation and analysis of processes and process validation, or demonstration on another airplane/validation (as described under process validation in this appendix, below) or a combination of these processes.
a. ETOPS Processes. The airplane-engine combination for which the certificate holder is seeking accelerated ETOPS operational approval must be ETOPS type design-approved (except for two-engine ETOPS at 75-minute authorization and for passenger-carrying airplanes with more than two engines manufactured prior to March 17, 2015) and be capable of operating at a satisfactory level of reliability before commencing ETOPS. The certificate holder seeking accelerated ETOPS operational approval must demonstrate to the FAA that it has an ETOPS program in place that consists of all the following applicable ETOPS process elements:
(1) The applicable process elements defined as the ETOPS maintenance and operations requirements of Chapter 3, paragraphs 301 through 304.
Appendix 3 NOTE: Passenger carrying airplanes with more than two engines are exempt from the ETOPS maintenance requirements. Therefore the operator may ignore the maintenance processes described in this Appendix.
(2) Documentation of the following elements as appropriate:
(a) Technology new to the certificate holder and significant difference in primary and secondary power (engines, electrical, hydraulic, and pneumatic) systems between the airplanes currently operated and the two-engine airplane for which the certificate holder is seeking ETOPS operational approval.
(b) The plan to train flight and maintenance personnel to the differences identified in the maintenance subparagraph above.
(c) The plan to use proven manufacturer-validated training and maintenance and operations manual procedures relevant to ETOPS for the two-engine airplane for which the certificate holder is seeking accelerated ETOPS operational approval.
(d) Changes to any previously proven validated training, maintenance or operations manual procedures used in previous non-ETOPS operations or in previous ETOPS with a different airplane-engine combination and/or geographic area of operations. Depending on the nature and extent of any changes, the certificate holder may be required to provide a plan for validating such changes.
(e) The validation plan for any additional certificate holder unique training and procedures relevant to ETOPS.
(f) Details of any ETOPS program support from the airframe manufacturer, engine manufacturer, other certificate holders or any other outside person.
(g) The control procedures when maintenance or flight dispatch support is provided by an outside person as described above.
b. Process Validation Methodology.
(1) Paragraph (a) identifies those process elements that should be proven before ETOPS authority is granted by the FAA under the accelerated ETOPS approval program. For a process to be considered proven the process should first be defined. Typically, this will include a flow chart showing the various elements of the process. Roles and responsibilities of the personnel who will be managing this process should be defined including any training requirement. The certificate holder should demonstrate that the process is in place and functions as intended. The certificate holder may accomplish this by thorough documentation and analysis, or by demonstrating on an airplane, that the process works and consistently provides the intended results. The certificate holder should define the necessary evaluation duration to validate the process and also show that a feedback loop exists to illustrate need for revision of the process, if required, based on in-service experience.
