Probable cause

the pilot's improper flare resulting in the hard landing and the fractured nose gear attachment, and the subsequent loss of control. Factors contributing to the accident were the high airspeed on approach, the pilot's improper in-flight planning/decision, and the pilot's inability to maintain directional control after the gear failure.

Analysis

A witness saw the airplane approach from the east. She said that the airplane came in "pretty fast" and touched down "approximately half way down the runway." The witness said, "The nose was down. He hit the ground and within 3 seconds he was off the runway and gone. Then all you saw was smoke." The witness said when the airplane hit "the front end shook. It wobbled like a kid on a tricycle. When it shook, it kind of looked like it [the airplane] bounced. Then it was gone." The control tower operator said he heard the captain say something over the radio, which caused him to look in the direction of the airplane. The tower operator saw the airplane off the runway, the main landing gear came off behind the airplane, and the airplane caught fire. The tower operator said he saw four people get out of the airplane. The airplane came to rest in a shallow ravine approximately 331 feet north of the runway. An examination of the airplane showed impact damage to the nose gear and nose gear wheel well. An examination of the airplane's systems revealed no anomalies.

Factual narrative

History of flight

On July 15, 2005, approximately 0930 mountain daylight time, a Gates Learjet Corporation 35A, N620JM, was substantially damaged, when during landing the airplane landed hard on the nose wheel and then departed the runway at the Eagle County Regional Airport (EGE), Eagle, Colorado. Following its departure from the runway, the airplane's landing gear collapsed and separated, and the airplane subsequently caught on fire. Visual meteorological conditions prevailed at the time of the accident. The unscheduled, domestic, on-demand charter flight from Aspen, Colorado (ASE), to EGE was operating on a visual flight rules flight plan under the provisions of Title 14 CFR Part 135. The captain and first officer sustained minor injuries. The two passengers on board the airplane sustained serious injuries. The flight departed ASE approximately 0915.

The pilot said the flight to EGE was normal. They entered a left downwind for runway 25 (8,000 feet by 150 feet, dry, asphalt). They were number two following a Boeing 737 airplane on a right downwind. The pilot said they made a normal approach and that the airplane was fully configured on an extended base leg. The pilot recalled that when they were 2 miles from the threshold, based on global positioning satellite coordinates, he could see the Precision Approach Path Indicator (PAPI) lights as 3 reds and 1 white, and that the Boeing 737 was on climb out. The pilot said the landing and touchdown were smooth, but when the nose wheel touched down, the airplane began an uncommanded right turn. The pilot said he used full left rudder and brakes in an attempt to regain control of the airplane. The airplane departed the runway surface and stopped well right of the runway.

The attending nurse on board the airplane said they approached the airport from the west. She said they made "a big banking turn to the south side of the airport and immediately set up for landing." She said she was looking out the window. "We were landing farther down the runway and tilting. We hit the ground hard and fast. I thought we'd abort the landing because we were far down the runway and going so fast ... Then the plane started to shake." The nurse said she shielded the patient's body from "stuff that was flying around in the back of the airplane." She said that the airplane's right wing struck the runway as they were going fast. She said they hit the ground, then they were back in the air again for a moment, then they hit the ground again. When the airplane came to a stop, the nurse said she started to get the patient out of the airplane. The patient told her that his back was broken. That's when she looked out the right side of the airplane and saw flames coming out.

A limousine driver that was waiting for the passenger and nurse to arrive at the fixed base operator (FBO) said she saw the airplane approach from the east. She said that the airplane touched down abeam the FBO, approximately half way down the runway. She said it was coming in "pretty fast." The witness said, "The nose was down. He hit the ground and within 3 seconds he was off the runway and gone. Then all you saw was smoke." The witness said when the airplane hit "the front end shook. It wobbled like a kid on a tricycle. When it shook, it kind of looked like it [the airplane] bounced. Then it was gone." The witness said, "I don't think those flappy things [thrust reversers] you see on the airplanes went out."

The control tower operator said he heard the captain say something over the radio, which caused him to look in the direction of the airplane. The tower operator saw the airplane off the runway, the main landing gear come off behind the airplane, and the airplane catch on fire. The tower operator said he saw four people get out of the airplane.

Meteorological information

At 0924, the wind conditions at EGE were 290 degrees at 4 knots.

Flight recorders

A thirty -minute digital cockpit voice recorder was located in the rear avionics section of the airplane. The recorder was sent to the National Transportation Safety Board Audio Laboratory on July 26, 2005, where the audio information was extracted. The times depicted are based on the 30 minute duration of the recording. The recording begins with the airplane arriving at Aspen on the previous flight. At 18:39 (18 minutes, 39 seconds tape duration), the crew departs ASE. At 24:03, the crew contacted EGE tower and reported they were 10 miles south of the airport. At 25:40, the crew extends the landing gear on left downwind.

At 26:44, EGE tower cleared the airplane to land on runway 25.

At 26:52, the captain read the final checklist. At 27:48, the first officer called for landing flaps. At 30:02, the first officer called for spoilers.

At 30:09, a "pilot expletive" was heard. At 30:11, the captain radioed "off the runway." At 30:14, a second "pilot expletive" was heard. The recording ended at 30:15 when power was removed from the device.

A summary of selected events which occurred during the recording is provided in the Cockpit Voice Recorder Group Chairman's Summary Report, as an addendum to this report.

Wreckage and impact information

The airplane came to rest in a shallow ravine approximately 331 feet north of the runway. An examination of the airplane showed the airplane's right side fuselage, beginning at the right wing root and running aft to the tail cone was charred and melted. The airplane's right engine nacelle pylon was bent downward. The engine nacelle, engine, and the pylon were charred and melted by fire. The airplane's left engine pylon was also bent slightly downward. The airplane's right wing, and aft portion of the right tip fuel tank were charred, melted, and consumed by fire. The left and right main landing gear and the main gear doors were fractured and separated aft. The nose gear was broken aft and crushed upward into the right bottom fuselage, aft of the nose gear wheel well.

An examination of tire tracks on the runway showed a set of two tire tracks to the left of a single tire track. The tire tracks began at the runway centerline and immediately veered from the centerline to the north side of the runway, continuing off the runway into the dirt. Of the tire tracks, the left set of tracks were heavy and distinct. Of that set, the farther left of the two was wider and darker than the other tire track. Of the single tire track, it was lighter than the left set of tire tracks. The track also showed a serpentine pattern that moved in and away from the left set of tire tracks.

Fire

The airplane sustained fire damage to the right upper aft portion of the fuselage, the tail cone, the right engine, the aft portion of the right wing, and right tip fuel tank. The fire origination was in the area encompassing the fuel pump and fuel lines to the right engine. Witnesses on the airplane stated they saw fire come from the front of the right engine nacelle. Airport fire personnel responded immediately and put out the fire.

Survival aspects

According to the nurse-passenger on board the airplane, after the airplane came to a stop, the patient-passenger told her that his back was broken. The nurse said she looked to the front of the airplane. The pilots got out and were running from the airplane. She said she did not see the pilots get out of their seats, open the door and leave the airplane because she was not conscious. When she woke up, the pilots were already outside. The nurse said she ran up to the door and yelled to the pilots to return to the airplane and help get the patient out. She said one of the pilots did return to assist her in getting the patient out of the airplane. The nurse said that a medical bag had to go with the patient and that the patient could not survive without it.

According to the patient-passenger, he had to hold on to the seat bac
