The Airbus A-380 was declared airworthy Tuesday, by the European Aviation Safety Agency and the U.S. Federal Aviation Administration after months of tests.
The certification is the last official hurdle that the world's largest jetliner has to clear before beginning commercial airline service.
The A-380 has been plagued by wiring problems that have delayed deliveries to airline customers by about two years, prompting canceled orders and penalties paid to customers.
Those problems caused the company's stock price to fall sharply, and have prompted an investigation of alleged insider trading.
French police raided offices of Airbus' parent company, EADS, on Tuesday, seeking evidence in the case.
