Release date: 10-June-2016

Course Information


Course Description:

Using the ARINC 668 standard as the base reference, this course will explain the Equivalency of Tool & Test Equipment (TTE) End to End process, that ensures compliance with the FAA and EASA requirements. Besides details on the process, actual examples and tips and tricks on Equivalency of Tooling & Test Equipment will be discussed with the students. 



Course Objectives:

The Student will learn the importance of Tool & Test Equipment Equivalency Process: 


• The reason why it is important to have the right Tool & Test Equipment, Lessons learnt from past aircraft crashes resulting from the use of incorrect TTE.

• How to establish the Equivalency of tool & test Equipment that would be acceptable to the Regulatory Authorities.

• Awareness of ARINC 668 Standards for TTE Equivalency.




Learning objectives:

This classroom training course will provide the following:



• awareness of TTE Equivalency Process

• detailed knowledge on the guidelines for the establishing TTE Equivalency



• avoid unnecessary Time Consuming Audit Finding resulting in expensive corrective follow up actions




Regulatory requirement compliance:

This course complies with TTE requirements detailed in EASA Part 145.A.40 Equipment Tools and Material and FAA CFR 14 Part 43.13(a)  Performance rules (general) and Part 145.109 (c) Equipment, materials, and data requirements.





The student must have a technical background in the Aviation / Aerospace Sector.
