HISTORY OF THE FLIGHT

On August 16, 1999, about 2347 (all times eastern daylight time), a Canadair CL-600, N63HJ, registered to Chaljet 1021 Holdings, Inc., and operated by Hop-A-Jet, Inc., as a Title 14 CFR Part 91 positioning flight from Pueblo, Colorado, to Fort Lauderdale, Florida, ran off the side of the runway, collided with a taxiway sign, and collapsed the nose landing gear while landing on runway 8 at Fort Lauderdale Executive Airport. Visual meteorological conditions prevailed at the time and an instrument flight rules flight plan was filed. The aircraft received substantial damage and the airline transport-rated pilot, first officer, and one flight attendant were not injured. The flight originated from Pueblo, Colorado, the same day, about 2018.

The captain stated they departed Fort Lauderdale Executive Airport on August 14, 1999, about 1220, en route to Durango, Colorado, with passengers. On taxi in at Durango, he had to make a sharp 180-degree turn and the nose steering "went off the rack". The nose wheel was turned to the right 60-80 degrees. After the passengers got off the airplane, he tried to use the steering tiller to get the nose steering back on the rack. This was not successful, and he called the operator's representatives at Fort Lauderdale. They told him to use a board to turn the nose wheel. He used a railroad tie and 4x6 inch board moved with a "come along" and the nose wheel turned and went back onto the rack. He then taxied the airplane and performed a high-speed taxi on the runway to 100 knots, and observed no problems with the nose steering. They spent the night at Durango.

Late in the morning on August 15, 1999, they departed for Santa Fe, New Mexico, where they picked up passengers and flew to Charleston, South Carolina. They spent the night at Charleston, and on the morning of August 16, 1999, about 0700, they departed for Newnan, Georgia, to pick up one passenger. After picking up this passenger, they flew to New Orleans, and dropped the passenger. They then flew to Houston, Texas, and picked up two passengers for Aspen, Colorado. After dropping the passengers in Aspen, they flew to Pueblo, Colorado, fuel. After refueling at Pueblo, they departed at 2018, en route to Columbia, South Carolina. About 1 hour 20 minutes into the flight, the left windshield cracked. He called the representatives of the operator in Fort Lauderdale, and was told to divert to Fort Lauderdale for repairs.

The captain stated the decent and approach to Fort Lauderdale were normal. On landing, when the nose-landing wheel touched down, the airplane veered to the left. He applied full right rudder and full right brake with no results. The airplane left the runway and came to a stop about 50 feet into the sand. They then evacuated the airplane.

The first officer stated he was the pilot flying and he was in the right pilot seat. As they approached to land at Fort Lauderdale Executive Airport, the captain briefed him that the landing would need to be firm for the airplane was light. The touchdown was firm, but not severe, on the main landing gear, near the runway centerline. As the nose wheel touched down he was attempting to deploy the thrust reversers. Simultaneously, the airplane began tracking to the left without command. As he began to apply brakes to regain control, he did not remember seeing the thrust reverser unlock lights illuminate. The airplane swerved faster to the left and he applied full right brake and rudder, while reducing power to idle. The airplane continued to deviate to the left, not responding to the right brake input. The airplane departed the runway surface, struck a taxiway sign, and came to rest on its main gear and collapsed nose gear.

The flight attendant stated the landing was firm, but not unusual. She then felt the airplane going sharply to the left and it started to jostle her in her seat. She heard a loud bumping sound and they came to an abrupt stop. She unfastened her seat belt and went to the front of the airplane where she met the captain and first officer. The first officer opened the door and they exited the airplane.

Review of the cockpit voice recorder transcript showed that 9 minutes before landing, the first officer asked the captain if he was tired. The captain replied, "been a long day." The first officer then replied "yeah we're not gonna have any trouble sleeping tonight." About 1 minute before touchdown, the captain told the first officer "remember you're only gonna probably have one reverser." A few seconds later the captain said, "ahhh go with the right TR." The first officer replied okay. The captain then said, "or excuse me the left one." The first officer replied, "I'll try 'em both and see what happens." Eight seconds before touchdown, the captain told the first officer to bring engine power to idle, and the first officer replied "roger." Three separate sounds of the airplane touching down are heard followed by two clicks and the increase in background noise. About three seconds later the sound of two clicks was heard again followed by a background noise increase, the sound of two thumps, the sound of impact, and the sound of the landing gear warning tone.

At the time of the accident the airplane had accumulated 9,503 total flight hours. The airplane received a 9,600-hour inspection on July 1, 1999, 123 flight hours before the accident.

METEOROLOGICAL INFORMATION

The Fort Lauderdale Executive Airport, 2353 surface weather observation was wind 110 degrees at 5 knots, visibility 10 statute miles, sky clear, temperature 83 degrees F, dew point temperature 75 degrees F, altimeter 30.12 in. Hg. At the time of the accident there was no visible moon or sun.

WRECKAGE AND IMPACT INFORMATION

The airplane came to rest east of the "G" taxiway and to the north of runway 8. Examination of the runway showed tire marks from the airplane were first visible about the 2,000-foot mark on runway 8. The marks are to the left of the runway centerline with the right wheel marks being seen almost on the centerline. Initially there are heavier tire marks from the left main gear tires, and about 160 feet further, heavy marks from the right main gear tires. Both sets of marks show alternating dark and light shades. There were no marks evident on the runway from the nose landing gear. The marks show the aircraft went off the left side of the runway just before the "G" taxiway, crossed the "G" taxiway, and that the nose landing gear struck the concrete base of a taxiway sign, located about 30 feet east of the "G" taxiway. The nose landing gear collapsed aft into the bottom of the airplane at this point and the airplane came to rest.

Examination of the nose landing gear tires from the airplane after the accident showed the left nose landing gear tire had a large cut and the wheel rim was damaged. Both nose tires had rubbing marks on the left sidewall. The nose tires had no flat spots or damage from sideways skidding. The nose tire pressures as measured with the airplane on jacks after the accident were left 141 and right 143 psi. The maintenance manual calls for 141 psi.

Examination of the main landing gear tires showed each tire had some rubber reversion consistent with higher than normal brake energy stops. There were no flat spots on the main tires. Tire pressures measured between 187-190 psi, with the airplane on jacks. The maintenance manual calls for 191 psi.

Examination of the brakes after the accident showed each main landing gear brake was released, and each tire and wheel turned freely. There was no evidence of brake overheat. The brake wear indicator for each brake was measured to be between .40 to .55 inches, which is within allowable limits.

The brake anti-skid system tested normally after the accident. Tire marks on the runway from the airplane showed an alternating light and dark shade, consistent with normal anti-skid operation.

Examination of the flight control system after the accident showed the elevator, aileron, rudder, elevator trim, rudder trim, aileron trim, and the ground and flight spoilers operated normally. The flight spoilers were found extended after the accident and the ground spoilers were found retracted. Representatives of Bombardier attributed the ground spoilers being retracted to loss of the weight on wheel system when the nose landing gear collapsed.

Examination of the engine thrust reverser system after the accident showed both engine thrust reversers operated normally when activated.

Examination of the nose landing gear and nose landing gear steering system after the accident showed no evidence of precrash failure or malfunction.

Testing of the weight on wheels system showed the system operated normally except for the nose landing gear target, which was damaged during the accident.

MEDICAL AND PATHOLOGICAL INFORMATION

The captain, first officer, and flight attendant were not injured. No post accident toxicology testing was performed on specimens from the captain, first officer, and flight attendant.
