BELLEVUE, Wash. (Oct. 17, 2018) – Sine Draco Aviation Technology (“Sine Draco”) and Sierra Completions today announced the selection of Sierra Completions by Sine Draco for engineering design of its A321 passenger-to-freighter converted aircraft (A321-200 SDF). Sine Draco is an aviation development company, with locations in the USA and China. It focuses on developing, managing and executing large-scale aviation projects, including aircraft design, modification, certification and investment management.


The A321-200 SDF aircraft design offers an economic solution for customers with an upper deck loading capability of 14 (88x125 or 88x108) unit load devices (ULDs) and 10 LD3-45 ULDs for the lower deck. 



“We have been working with the Sierra Completions team for the past year on the design of the Sine Draco A321-200 SDF. The partners involved in the project have made significant progress and we are very pleased that we can further expand our relationship with Sierra Completions toward conclusion of the remaining design needs toward the Supplemental Type Certificate,” said Alex Deriugin, CEO of Sine Draco Aviation Technology Ltd.


Sierra Completions serves private sector, VVIP and head-of-state clientele by modifying transport-category aircraft for interior and mission requirements. Featuring world-class engineering and design, Sierra Completions applies the cutting-edge systems, technology, schedule performance and integration excellence for which its parent company, Sierra Nevada Corporation, has been recognized for 50 years, to deliver innovative, customer-focused solutions in the aircraft completions and modification sector.


“Sierra Completions is proud to be part of the Sine Draco team on the A321-200 SDF project,” said Ed Topps, Sierra Completions vice president of programs. “This aircraft presents a unique challenge as we work toward completion of the passenger-to-freighter capability, and it’s one that I know Sierra Completions has the expertise not only to complete but with which to exceed Sine Draco’s expectations. I look forward to the upcoming months working side by side with Sine Draco.”
