ALBUQUERQUE (AP) - Eclipse Aviation says pilot error caused one of its test jet airplanes to make a belly landing at Albuquerque's international airport. The Albuquerque-based company says there were no mechanical or electrical problems that caused the airplane to touch down Saturday with its landing gear retracted. Company president Vern Raburn says the airplane will fly again. Eclipse has five test jet airplanes. The company is developing the Eclipse 500 -- a twin-engine, six-seat airplane. Raburn has said the company wants to achieve Federal Aviation Administration certification next year. Eclipse plans to sell the airplanes for about $1.3 million each.
