## Factual narrative

On December 7, 2008 at approximately 1815 central standard time (CST) a twin-engine turbo fan, Learjet 23, Mexican Registration XC-LGD, was destroyed when it impacted a lake while on final approach to an unlit day visual flight rules airport near Tlaxcala, Mexico. The pilot and copilot received fatal injuries. The aircraft was observed to have a high rate of descent on short final and a witness stated he lost visual contact. When the airplane did not reappear after about 40 seconds, he drove to the landing threshold of the runway to check the status. Other persons at the airport boundary indicated the airplane crash landed into the lake to the north of the airport. The flight was terminating at the time. The aircraft is being recovered to a facility in Tlaxcala, Mexico for further investigation. A technical advisor from Bombardier-Learjet Inc. has been appointed to provide technical assistance to the DGAC in the recover effort and conduct of the investigation. The investigation is under the jurisdiction of the Government of Mexico. This report is for information purposes only and contains only information released by the Government of Mexico.
