A faulty indicator light prompted pilots to land an Air Force Osprey aircraft in a wheat field southwest of Amarillo on Wednesday, officials said.

The three-member crew was flying a standard test flight at 1:20 p.m. when they decided to land the tiltrotor aircraft near Greyhawk Landing, in a field just off the intersection of West Costley and Helium roads, officials said. No one was hurt, and the CV-22 Osprey was not damaged, officials said.

Pilots later flew the aircraft back to Bell Helicopter's Amarillo plant, the final assembly line stop for the V-22 Osprey. The aircraft was scheduled for delivery later this month, officials said.

The V-22 Osprey is a fixed-wing plane with rotors that tilt to take off and land like a helicopter. It is manufactured in a joint venture between Bell and Boeing. The company assembles two types of Ospreys - the MV-22 for Marines and the CV-22 for Air Force Special Operations Command - under multiyear federal procurement contracts.

Bell routinely flies all its aircraft on what Bill Schroeder, a Bell spokesman based at the company's headquarters in Fort Worth, described as "a robust series of maintenance flight tests" before delivery.

A Huey helicopter landed shortly after the Osprey touched down Wednesday. It also is standard procedure for a rescue helicopter to stay available during test flights, said J.J. Walker, a Bell spokeswoman.

Walker said precautionary landings typically mean no one has found any problems with the aircraft, and the pilots chose to land at the site because of the open space.

A flight safety crew responded shortly after the landing, and a parts truck later followed, Walker said. Maintenance crews fixed the problem in the field, officials said.

The rescue helicopter circled around the area before the Osprey once again came to life.

The powerful aircraft blew plumes of dust into the air as it took off shortly after 4 p.m. and headed to Bell for further examination, officials said.

Federal Aviation Administration spokesman Lynn Lunsford said the agency does not have any authority over these types of incidents "because the aircraft is a military product, being operated by a contractor for the Pentagon."

Taylor Hendrickson, 22, said he was hunting prairie dogs when he heard what he said sounded like a diesel motor nearby.

"I turned around, but didn't see anything," Hendrickson said. "We drove to the eastern end of the fence line, looked over and saw (the aircraft)."

Hendrickson said he has checked the fence line of the nearly 650-acre field and protected the cattle from coyotes and prairie dogs for about eight years. He said he has never seen any landings in the field before Wednesday.
