Adopting a new engine would have resolved noise and fuel economy issues. Following the fall of the Ceauşescu regime, plans were made to restart production using the Rolls-Royce Tay. British aircraft leasing company Associated Aerospace agreed a $1 billion deal to purchase 50 Tay-powered One-Elevens fitted with a new electronic glass cockpit for onward leasing to Western customers. The liquidation of Associated Aerospace in April 1991 stopped this deal. Despite this setback, Rombac continued to try to sell the One-Eleven, with US operator Kiwi International Air Lines placing a firm order for 11 Tay-engined aircraft with options for an additional five, but these plans never happened.
