BOSTON (AP) — The Federal Aviation Administration has again ruled that the Cape Wind offshore wind project poses no hazard to local airplanes, months after a federal appeals court forced it to reconsider.

The FAA said in a statement Wednesday that after an aeronautical study, it had determined the project’s 130 turbines wouldn’t endanger local air traffic.

Last October, a federal appeals court overturned a previous FAA clearance of the wind farm, saying the agency hadn’t adequately considered the project’s effect on pilots who fly by sight only.

It’s the fourth time the FAA has cleared the controversial project. A Cape Wind spokesman said the company was pleased, and the project is now closer to reality.

The approval comes as two powerful U.S. Congressmen are asking the FAA to prove its previous Cape Wind clearance wasn’t politically motivated.
