Transportation Secretary Sean Duffy is meeting chief executives from Boeing, GE and other major aerospace companies on Wednesday to discuss reforms aimed at speeding Federal Aviation Administration approvals for new aircraft. Duffy has cited competition from China, while FAA Administrator Bryan Bedford has backed efforts to streamline certification. The FAA proposed changes in June to modernize the process and reduce reliance on exemptions, special conditions and equivalent-safety findings. New-aircraft certification can take five or more years and requires extensive testing, data and documentation. Boeing’s 737 MAX 7 took more than eight years to certify and was approved in August, while the 777X is more than five years behind its original schedule. Duffy also called for greater competition and faster innovation in commercial space.
