Technologies Harness Scanner Inc. Enters into a Collaborative Agreement with Jazz Aviation LP and Bombardier Aerospace

Montreal, October 7, 2011

On June 10, 2011, Technologies Harness Scanner Inc. (THS) entered into a collaborative agreement with Jazz Aviation LP (‘’Jazz’’) and Bombardier* Inc. (‘’Bombardier’’) to develop and implement turnkey solutions to facilitate the maintenance and troubleshooting of electrical sub-systems for the following aircraft operated by Jazz: CRJ100* and CRJ200* regional jets CRJ700* and CRJ900* regional jets Dash 8* series turboprops Q400* turboprops.

THS will provide Jazz MRO operations with turnkey solutions for all of its Bombardier aircraft, including: Two (2) portable automated test equipment (ATE) for line or heavy maintenance bases, Updated maintenance processes to meet Jazz and Bombardier maintenance practices, Specific tool packages for each sub-system, and Training for Jazz avionic and mechanic technicians.

Jazz purchased the systems and, in addition, is contributing by providing its extensive maintenance expertise, as well as aircraft and manpower to deploy this new technology into the line and heavy fields of maintenance.

Bombardier is supporting the project with financial and technical considerations to facilitate an easy transition.

About Technologies Harness Scanner:

THS is a leader in providing automated solutions to improve the speed and reliability of electrical maintenance aboard aircraft. They have developed innovative products and processes for the detection and troubleshooting of electrical sub-systems that enable fleet operators to conduct in-situ diagnostics of new or legacy aircraft, with a focus on both conformity and ageing of the specific electrical sub-systems. The performance objective is to carry-on a full system test with a turnaround time of 40 minutes at a scheduled line maintenance visit instead the many hours required at a fault occurrence with traditional methods; the system can also be used with the same time performance on the line at the diagnostic level. The results of this expert system are immediate, with faults identified, localized and documented on the spot, resulting in improved aircraft reliability, reduction in non scheduled maintenance and better safety. THS ATE test system is an agile, plug and play expert tool that fits in an aircraft carry-on case and permits testing of an entire sub-system of up to 1000 test points in a few minutes, locating open/short and intermittent faults as well as electrical subsystem degradation prior to failure using multiple technologies.
