An investigator from the National Transportation Safety Board arrived on the scene in N.H. on Monday night.

Investigators found no signs of pre-crash failure in the engine, wings, or propellers of a plane that plummeted to earth Monday at a New Hampshire airfield, killing two men, a National Transportation Safety Board spokesman said Tuesday.

David Ingalls, 77, and Bruce Anderson, 62, both of Kingston, N.H., died Monday when the plane Ingalls was flying appeared to stall during takeoff and crashed into a cluster of trees at the Hampton Airfield in North Hampton.

NTSB spokesman Todd Gunther said an airframe specialist would examine the frame of the aircraft on Wednesday for potential problems.

The NTSB will also examine the physiology of the two men on board for any signs of what caused the crash, Gunther said at a Tuesday news conference.

Witness Bob Lamothe, 52, of Hampton, N.H., said the plane “just dropped out of the sky. . . . At first, I couldn’t believe I saw what I just saw.”

Lamothe said takeoff looked normal until the nose of the plane suddenly “went up at a very severe angle” before losing speed, overturning, and falling.

An investigator from the safety board arrived Monday night and began the on-scene phase of the investigation Tuesday, said Peter Knudson, another NTSB spokesman.

The NTSB is investigating with the Federal Aviation Administration, New Hampshire State Aeronautics Division, New Hampshire State Police, and North Hampton police.
