1.1 This guide serves as an endorsement to the Aircraft Electronics Technician (AET) and Federal Aviation Administration (FAA)/European Union Aviation Safety Agency (EASA) Airframe and Powerplant (A&P) Mechanic Training, and to address the fundamental subject knowledge, task performance, and task knowledge activities and functions for a digital engine monitoring systems technician.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This guide is intended to be used to assess competencies of qualified individuals who wish to receive the Digital Engine Monitoring Systems Technician endorsement through any certification program.

4.2 This guide is intended to be used in concert with a certification provider’s structure and materials for management, exam delivery, and candidate preparation.

4.3 The knowledge, skills, and abilities (KSA’s) identified in this guide shall be assessed by levels of competency as referenced in Table 1.

4.4 This guide identifies KSA levels for three skill-level technicians: apprentice (A), journeyman (J), and master technician (M).

• 4.4.1 An “apprentice” is defined as an inexperienced technician who is learning by practical experience under a skilled worker.
• 4.4.2 A “journeyman” is defined as a trained, skilled worker who is considered competent and authorized to work as fully qualified employee.
• 4.4.3 A “master technician” is a highly trained expert in the field who often uses technology and tools to troubleshoot complex issues, oversees and signs off the work of other technicians, and conducts on-the-job training for apprentices and journeyman.

4.5 Each KSA in this guide correlates the minimum skill level for each of the three levels of technician in parentheses following each line (for example: (A1, J2, M3), meaning the apprentice is required to know the standard to a Level 1, a journeyman a Level 2, and a master technician should know the standard to a Level 3).

4.6 This system includes a level “0” which means the standard is not required for the associated skill level (for example: (A0, J1, M2) meaning an apprentice is not required to know that particular standard, but a journeyman is required to know the standard to a Level 1, and a master technician should know the standard to a Level 2).
