Probable cause

The pilot's misjudged distance and speed during the approach to landing, and his failure to obtain the proper touchdown point resulting in an overrun. A contributing factor was the pilot's failure to abort the landing.

Analysis

The cargo flight was cleared for a visual approach to the 5,000-foot long, by 150-foot wide asphalt runway. Based on estimated landing weight of the aircraft, the Vref was estimated at 116 KIAS. Air traffic Control (ATC) radar data revealed that the flight maintained a ground speed above 190 knots on final approach, to include the touchdown zone for runway 13. The first evidence of braking was noted at a point 1,247 feet from the departure end of the runway. Braking signatures on the asphalt as well as off the pavement were consistent with an operational anti-skid system. Witnesses at the airport also observed the airplane flying very fast and touching down long. Both crewmembers, the 4,689-hour captain and the 2,873-hour first officer, were familiar with the airport, and the flight was 20 minutes ahead of its scheduled arrival time. The airplane overran the departure end of runway 13, impacted the airport perimeter fence, proceeded across a roadway, took out another fence, and collided with two trees in a cemetery. The airplane was found to be within weight and balance limits for all phases of the flight. The installed cockpit voice recorder (CVR) was found not to be functional.

Factual narrative

History of flight

On September 19, 2003, at 1710 central daylight time, a Learjet 25B, twin-turbo jet airplane, N666TW, operating as Ameristar Jet Charter Flight 982 was destroyed upon collision with trees and terrain when it overran the departure end of runway 13 while landing at the Del Rio International Airport (DRT), near Del Rio, Texas. The airline transport rated captain was fatally injured, and the airline transport rated pilot acting as first officer was seriously injured. Visual meteorological conditions prevailed for the 14 Code of Federal Regulations (CFR) Part 91 repositioning flight. The airplane was owned by Sierra American Corporation of Wilmington, Delaware, and was being operated by Ameristar Jet Charter, Inc., of Dallas, Texas, a 14 CFR Part 135 on-demand air taxi cargo operator. An instrument flight rules (IFR) flight plan was filed for the flight which originated from the El Paso International Airport (ELP) at approximately 1625, destined for DRT.

The operator reported that on the day of the accident the flight originated from Jackson Hole, Wyoming, early in the morning, making intermediate stops at Los Angeles, California, and El Paso, Texas. The flight was scheduled to arrive at DRT at 1730.

According to personnel at the airport, a transmission in the blind was heard on the Unicom, reported "Five miles north, landing 13." The airplane had been cleared by approach control for a visual approach to runway 13.

A witness who was standing outside the Fixed Base Operator (FBO) facilities at the airport stated that the airplane was "high and fast" and he was expecting the airplane to execute a go-around. A second witness, also on the airport ramp stated that the airplane was going so fast that he "thought the airplane was taking off instead of landing."

A third witness, who was doing some outdoor painting and was concerned with over-spraying aircraft on the ramp stated that he observed the wind sock at the time of the landing and he added that the airplane landed with a slight downwind. Another witness observed "that the airplane was going very fast" and noted that the airplane landed past Taxiway Charlie. Taxiway Charlie is located about 1,875-feet short of the departure end of Runway 13.

The pilot of a King Air on the ramp reported that he observed the airplane landing and that the flaps appeared to be fully extended. This witness reported that he did not hear the engines spool-up in an attempt to abort the landing.

The airplane overran the departure end of runway 13, impacted the airport perimeter fence, proceeded across a roadway, impacted another fence, struck two trees and displaced multiple headstones.

A person at the FBO that was monitoring the Unicom transmissions reported that a female voice was making all of the radio transmissions. The operator stated that the company policy is for the non-flying pilot (NFP) to make all of the radio calls, thus the captain was expected to be functioning as the flying pilot (FP).

No reported distress calls were received from the crew of the airplane prior to the accident.

Personnel information

The Captain

The 29-year old captain held an airline transport pilot certificate with the ratings of airplane multiengine land, commercial privileges for airplane single-engine land, and type ratings for DA-20 and LR-25. The captain's most recent first class medical certificate was issued on March 4, 2003, with a restriction "must wear corrective lenses" Federal Aviation Administration (FAA) medical records indicate that the pilot had waiver for a color vision deficiency.

Company records revealed that the captain had accumulated a total of 1,348 hours in the make and model of the accident airplane, with 343 hours as pilot-in -command (PIC), and approximately 1,005 hours as second-in-command (SIC) in the same airplane. The captain had flown a total of 231.7 hours in the preceding 90 days, with 85 within the last 30 days, and 4.5 hours in the last 24-hours.

His upgrade training to captain was completed on August 3, 2002. Last recurrent training was completed on March 21, 2003. The captain's last proficiency check indicated satisfactory performance in all areas.
