4.7Reliability Program

4.7.1 An ETOPS reliability program will be developed or the existing reliability program supplemented as applicable. This program should be designed with early identification and prevention of ETOPS related problems as the primary goal as well as ensuring that the minimum ETOPS reliability levels are maintained. The program should be event-oriented and incorporate reporting procedures for significant events detrimental to ETOPS flights. This information will be readily available for use by the operator and Transport Canada to help establish that the reliability level is adequate, and to assess the operator's competence and capability to safely continue ETOPS. An ETOPS reporting program will be established by the operator to ensure that Transport Canada is notified at least monthly, or more often if events reportable through this program are identified.

4.7.2 The operator must also ensure that procedures are established and implemented that will roll back the approved ETOPS diversion time should the engine in flight shutdown rate exceed the limits specified in AppendixA. The appropriate maintenance management level must be authorized to initiate roll back of the approved ETOPS diversion time.

4.7.3 Where reliability data indicates that the "target criteria" per AppendixA, Figure1, is no longer being met, the operator must notify Transport Canada with corrective action measures. Where the "minimum criteria" is no longer being met, the operator must roll back the ETOPS diversion time to that specified in the appendix for the particular IFSD rate noted.

4.7.4 Failure for an operator to roll back the maximum diversion time when required will constitute grounds for removal of ETOPS authority.

4.7.5 In addition to the requirements of Chapter591 of the Airworthiness Manual, the following items will be included in the reporting program:

  1. in-flight shutdowns or flameouts;
  2. diversion or turnback;
  3. uncommanded power changes or surges;
  4. inability to control the engine or obtain desired power;
  5. problems with systems critical to ETOPS (engine bleed air, pressurization, electrical power, etc.).

4.7.6 The report will also identify the following:

  1. aircraft identification;
  2. engine identification (make and serial number);
  3. total time, cycles and time since last shop visit;
  4. for systems, time since overhaul or last inspection of the defective unit;
  5. phase of flight; and
  6. corrective action.
