Study Notes

Service Difficulty Reports (SDR)

  • Governed by CAR 521, Division IX (CAR 521.401 to CAR 521.403).
  • A "service difficulty" includes any failure, malfunction, or defect in an aeronautical product.
  • A "reportable service difficulty" affects or is likely to affect the safety of an aircraft, its occupants, or any other person if not corrected.

Reporting Requirements (CAR 521.401, AC 521-009)

  • A person must submit a separate service difficulty report to the Minister for each reportable service difficulty.
  • The report must contain the information specified in the Service Difficulty Report form published by the Minister.
  • Reports can be submitted electronically (e.g., Transport Canada web service difficulty reporting system) or by mail/courier.
  • All documents issued after 01 Feb 2007 are now published as Staff Instructions.

Time Limits (CAR 521.402)

  • A service difficulty report must be submitted to the Minister within three working days after discovering the reportable service difficulty.
  • If all information is unavailable within this period, an interim report can be submitted within three working days, including the following:
  • Aircraft registration (if applicable).
  • Date of the occurrence.

Interim SDR and Follow-Up

  • If an interim SDR is filed, a complete service difficulty report must be submitted within 14 days after discovering the reportable service difficulty.

Non-Duplication of Reporting

  • A service difficulty report is not needed for a reportable service difficulty already reported by another person or organization.

AMO and AME Responsibilities

  • Active participation from individuals and organizations in the aviation community is crucial for the SDR system to be effective.
  • AMEs should participate in the continuous exchange of information within the SDR framework to improve safety across the industry.

Web-Based SDR System (WSDRS)

  • Developed in response to requests from the Canadian aviation industry.
  • It is intended to be a web-based, fast, convenient, and confidential reporting system.
  • Because of experience gained over the years, TCCA has been able to develop new regulatory requirements
  • Improved methodology for SDR.
  • TCCA is now more informed in ability to develop corrective action based on reported service difficulties of an aeronautical product, component, equipment or part.

Submission of Service Difficulty Report

  • Form Number 24-0038E.
  • The submission to the minister must be made either electronic means or by mail or courier.
  • The Service Difficulty Report may also be faxed to Transport Canada.
  • Can be found at https://tc.canada.ca/en/aviation/reference-centre

Transport Canada's Role

  • Inputs the report into a database to track failures, malfunctions, or defects.
  • Communicates these events to owners and AMEs for safety purposes.

SDR Hierarchy

  • SDRs can lead to Airworthiness Directives (ADs), Civil Aviation Safety Alerts (CASAs), and Feedback Articles.

Computerized Airworthiness Web Information System (CAWIS)

  • A national, computer-based information system providing Aircraft Certification, Maintenance and Manufacturing, and Airworthiness offices access to current airworthiness data on Canadian-registered aircraft.
  • Enables effective monitoring of the Canadian fleet's airworthiness by 300-400 registered users.

Feedback

  • Is a Transport Canada publication.
  • All service difficulties that are reported, will be published in magazine.
