On February 13, 2008, about 1000 Hawaiian standard time, a Bombardier, Inc., CL-600-2B19, N651BR, operated by Mesa Airlines, dba GO!, Phoenix, Arizona, overflew its destination airport, General Lyman Field (HTO), Hilo, Hawaii, while in cruise flight. The airplane subsequently reversed course, descended, and landed uneventfully at HTO. The incident occurred during a regularly scheduled, domestic, passenger flight, which was conducted in accordance with 14 CFR Part 121, and an instrument flight rules flight plan was filed and activated. The airplane was not damaged, and there were no injuries to the 40 passengers or 3 crewmembers. The flight originated from the Honolulu International Airport, Honolulu, Hawaii, about 0916.
According to air traffic control personnel, the airplane was in cruise flight at 21,000 feet when the controller made several unsuccessful attempts to contact the flight crew. About 1000, the controller was able to established radio contact with the flight crew, but only after the airplane had overflown HTO by about 15 miles. The controller then issued the flight crew a course change back to HTO, where it landed about 15 minutes later.
Company maintenance personnel subsequently performed a functionality check on the airplane's pressurization system. The check proved negative for any system anomalies. Additionally, the airplane was checked for carbon monoxide exposure with negative results.
