WASHINGTON, Jan 21 (Reuters) - The head of the Federal Aviation Administration said on Wednesday the agency is not the roadblock to Boeing BA.N winning certification of two new variants of the Boeing 737 MAX.

FAA Administrator Bryan Bedford told reporters after a speech in Washington the agency has devoted significant resources to helping Boeing get the smaller 737 MAX 7 and larger MAX 10 planes certified "but Boeing still has to do their work ... We can only help get them there, but they have got to do the work, and they're doing the work." Bedford added "I don't think FAA is the roadblock on 7 and the -10 certification."
