Boeing began testing the landing gear of the first of its new 787 Dreamliner jets Saturday, as the airplane nears readiness for first flight in about three months.

The tests involve swinging the landing gear into a stowed position and back down into a landing position to verify that it works as it should on a regular flight.

The gear action is initiated from the plane’s flight deck and requires the successful integration of the airplane’s electronic and hydraulic systems with its structural parts.

The nose and the main gear parts were tested independently and then jointly. Testing continues this week.
