TS 1400 for T129 Mk-I ATAK Helicopters
The TEI TS1400 Turboshaft Engine can also be integrated into T129 Mk-I ATAK Helicopter with some adaptations to replace LHTEC CTS800-4A Engines for which Turkey has been experiencing difficulties for several years in obtaining an export license from the U.S. Government. In 2015 Turkey had finalized negotiations with Turkmenistan for the sale of 2 T129 Mk-I ATAK Helicopters however since the U.S. Government did not provide the export license for the LHTEC CTS800-4A Engines this project was not realized. A similar problem is being experienced for the sale of the T129 Mk-Is to Pakistan. Turkey has been waiting for more than a year for the U.S. export license in order to proceed with the Pakistan T129B Mk-I deal.
The contract for the sale of 30 T129B Mk-I ATAK Light Attack and Tactical Reconnaissance Helicopters to Pakistan Land Forces was signed on 16 May 2018, yet it has not become effective as of June 2019. Official application to the U.S. Government regarding the export license of the LHTEC CTS800-4A Turboshaft Engine utilized on the helicopter was made, the process was completed with the Foreign Affairs Commission and the request was submitted to the U.S. Department of Defence. The approval process was still underway as of May 2019. Turkish Aerospace previously received the Original License Document from the U.S. Government for the sale/export of the T129B to Pakistan.
