N55LF
Learjet 55
The flight was a VFR positioning flight from FLL to FXE. Transcripts of the cockpit voice recorder (CVR) showed that while waiting for takeoff from FLL the flightcrew heard the local controller reported to a Delta Airlines flight that was on a seven mile final approach to land on runway 27R that the winds were 250 degrees at 19 knots, gusting to 50 knots. The Delta Airlines flight crew then informed the controller they were making a missed approach. At 1130:05 the captain asks the first officer if "can you see the end of the weather? If we make a hard right turn, can we stay clear of it?" The first officer responded "I believe so." At 1130:06 the local controller reported "wind shear alert. The centerfield wind 230 at 22. Runway 27R departure 25 knot loss one mile departure." The captain stated to the first officer "sweet." At 1132:11 the captain transmitted to the local controller "tower, any chance of Hop-a-Jet 55 getting out of here?" The local controller responded wind 230 at 17, right turn direct FXE approved, runway 27R cleared for takeoff. The captain responded "cleared to go, right turn out." At 1133:10 the captain asks for gear up. At 1133:15 the local controller responded to a Southwest Airlines Flight waiting for takeoff "no, don't look like anyone's gonna go." "The uh, weather is due west moving rapidly to the north. It looks like a few minutes, and you all be in the clear straight out." At 1133:17, the captain stated to the first officer "oh #. Think this was a bad idea." The first officer responded "no airport in sight." At 1133:43 the sound similar to precipitation hitting the windshield is recorded. At 1133:46 the FLL local controller instructs the flight crew to contact FXE Tower. At 1133:54 the CVR records the FXE local controller transmitting "wind 200, variable 250 at 15, altimeter 29.99. Heavy cell of weather to the west moving eastbound. Low level wind shear possible. At 1134:16, the FXE local controller transmits "attention all aircraft, low level wind shear advisories are in effect. Use caution. Wind 240 at 10." At 1134:51, the first officer transmitted to the FXE local controller that the flight was over the shoreline inbound full stop. At 1135:02, the FXE local controller transmitted "Hop-a-Jet 55, Executive tower, wind 210 variable 250 at 35, 35 knots and gusting. Winds are uh, heavy on the field. Low level wind shear advisories are in effect. Heavy rains from the west, eastbound and would you like to proceed inbound and land Executive? Say intentions." The first officer responded "that's affirmative." The local controller responded, "Hop-a-Jet 55 straight in runway three one if able. The winds 230 gusts, correction, winds 230 variable 210 at 25." At 1135:48, the local controller transmitted, "Hop-a-Jet 55, wind 230 variable 300 at 25 gusts 35. Altimeter 30.00. Runways are wet. Traffic is exiting the runway prior to your arrival, a Dutchess. Caution standing water on runways. Low level wind shear advisories in effect, Runway 31. Cleared to land." The first officer responded "cleared to land, Hop-a-Jet 55." At 1136:35, the local controller transmitted "wind 230 at 25, gusts 35." At 1136:58, the CVR records the sound similar to precipitation on the windshield. At 1137:17, the CVR records a sound similar to the aircraft touching down on the runway. At 1137:19, the sound of a repetitive tone similar to the thrust reverser warning starts and continues to the end of the recording. At 1137:23 a loud unidentified roaring sound starts and lasts 8 seconds. At 1137:30, loud rumbling noises similar to the aircraft departing the runway start. At 1137:36, a continuous tone similar to landing gear warning signal sounds and continues to the end of the recording. The rumbling noises stop. At 1137:39 the captain states the thrust reversers didn't stow and at 1138:36, the captain states "I went around and the # TRs stayed. The CVR recording ended. The 1132, Goes-12 infrared image depicts a rapidly developing cumulonimbus cloud between and over the FLL and FXE airports. The top of the cloud over FXE was in the range of 22,000 feet. The top of the cloud southwest of FXE was in the 39,000 feet range. The 1145, Goes-12 infrared image depicts a developing cumulonimbus cloud over FXE with the cloud top in the 42,000 feet range. Data was obtained from the Melbourne, Florida Doppler Weather Radar System, located 118 miles north-northwest of the accident site. The data showed that at FXE, between 1130 and 1145, a VIP Level 1 to 2 echo evolved into a VIP Level 5 "intense" echo at 1135 and a VIP Level 6 "extreme" echo by 1145.
History of Flight On July 19, 2004, about 1137 eastern standard time, a Gates Learjet 55, N55LF, registered to 55-112, LLC and operated by Hop-A-Jet Inc., as a Title 14 CFR Part 91 positioning flight, overran runway 31 during landing roll at the Fort Lauderdale Executive Airport (FXE), Fort Lauderdale, Florida. Visual meteorological conditions prevailed prior to the accident and no flight plan was filed. The airline transport-rated captain and the commercial-rated first officer reported no injuries, and the airplane incurred substantial damage. The flight originated from the Fort Lauderdale-Hollywood International Airport (FLL), Fort Lauderdale, Florida, the same day, about 1133. The captain stated the flight was intended to be a simple reposition of a Lear 55, N55LF from FLL to FXE. They departed FLL with their eyes on the weather, which was building to the west and southwest of the Fort Lauderdale area, intending to land at FXE prior to the arrival of the rain. Unfortunately, after an uneventful and quick flight, the weather impacted the active runway at FXE (runway 31) just as, or possibly seconds before their touchdown. Brakes and thrust reversers were applied immediately upon contact with the ground and it was quickly very obvious that due to one, or any combination of factors, the brakes were going to be completely ineffective. The decision was then made to attempt a go-around maneuver. Again, due to one or more factors, they were unable to attain liftoff speed and exited the runway which destroyed the aircraft. The first officer stated that after a reposition flight from FLL to FXE, they were cleared to land on runway 31 at FXE. Visual meteorological conditions existed at the time of approach to touchdown, at which point, a fast moving thunderstorm enveloped the aircraft and subsequently degraded the landing surface with heavy rainfall. Heavy braking and the deployment of thrust reversers were unable to stop the aircraft in the available landing distance. The aircraft departed the end of the runway 31 and came to rest approximately 1,000 feet beyond the departure end. No injuries were sustained by him or the captain. Two witnesses, who are airport firemen, were located on the north side of the airport fire station. They stated they were observing a thunderstorm that was rapidly closing on their position from the southwest. They heard what sounded like a jet landing on runway 31. They looked toward the runway and observed a Lear 55 with reversers engaged attempting to stop. They realized the aircraft would not be able to stop with the remaining runway. They responded to the scene with the fire truck and at this time heavy rain, gusty winds, and lightning had closed in on the airport. The aircraft had crashed through a chain link fence, broken off the main landing gear, and come to rest in a sandy drainage ditch. The aircraft was leaking fuel. They foamed the aircraft and then opened the main cabin door where they were advised by the flight crew that they were not injured. They then opened the emergency exit and the flight crew exited from it. The air traffic controllers in the FXE control tower at the time of the accident stated that N55LF, operating as Hop-a-Jet flight 55, was cleared to land on runway 31. They observed the airplane touch down on runway 31 near the "C" taxiway, run off the runway into the grass, cross over taxiway "F", and come to rest. Transcripts of the cockpit voice recorder (CVR) showed that at 1112:04, the first officer requested permission to taxi to the active runway at FLL. The ground controller cleared the flight to runway 27R. At 1127:30, the local controller reported to a Delta Airlines flight that was on a seven mile final approach to land on runway 27R that the winds were 250 degrees at 19 knots, gusting to 50 knots. The Delta Airlines flight crew then informed the controller they were making a missed approach. At 1130:05 the captain asks the first officer if "can you see the end of the weather? If we make a hard right turn, can we stay clear of it?" The first officer responded "I believe so." At 1130:06 the local controller reported "wind shear alert. The centerfield wind 230 at 22. Runway 27R departure 25 knot loss one mile departure." The captain stated to the first officer "sweet." At 1132:11 the captain transmitted to the local controller "tower, any chance of Hop-a-Jet 55 getting out of here?" The local controller responded wind 230 at 17, right turn direct FXE approved, runway 27R cleared for takeoff. The captain responded "cleared to go, right turn out." At 1133:10 the captain asks for gear up. At 1133:15 the local controller responded to a Southwest Airlines Flight waiting for takeoff "no, don't look like anyone's gonna go." "The uh, weather is due west moving rapidly to the north. It looks like a few minutes, and you all be in the clear straight out." At 1133:17, the captain stated to the first officer "oh #. Think this was a bad idea." The first officer responded "no airport in sight." At 1133:43 the sound similar to precipitation hitting the windshield is recorded. At 1133:46 the FLL local controller instructs the flight crew to contact FXE Tower. At 1133:54 the CVR records the FXE local controller transmitting "wind 200, variable 250 at 15, altimeter 29.99. Heavy cell of weather to the west moving eastbound. Low level wind shear possible. At 1134:16, the FXE local controller transmits "attention all aircraft, low level wind shear advisories are in effect. Use caution. Wind 240 at 10." At 1134:51, the first officer transmitted to the FXE local controller that the flight was over the shoreline inbound full stop. At 1135:02, the FXE local controller transmitted "Hop-a-Jet 55, Executive tower, wind 210 variable 250 at 35, 35 knots and gusting. Winds are uh, heavy on the field. Low level wind shear advisories are in effect. Heavy rains from the west, eastbound and would you like to proceed inbound and land Executive? Say intentions." The first officer responded "that's affirmative." The local controller responded, "Hop-a-Jet 55 straight in runway three one if able. The winds 230 gusts, correction, winds 230 variable 210 at 25." At 1135:48, the local controller transmitted, "Hop-a-Jet 55, wind 230 variable 300 at 25 gusts 35. Altimeter 30.00. Runways are wet. Traffic is exiting the runway prior to your arrival, a Dutchess. Caution standing water on runways. Low level wind shear advisories in effect, Runway 31. Cleared to land." The first officer responded "cleared to land, Hop-a-Jet 55." At 1136:35, the local controller transmitted "wind 230 at 25, gusts 35." At 1136:58, the CVR records the sound similar to precipitation on the windshield. At 1137:17, the CVR records a sound similar to the aircraft touching down on the runway. At 1137:19, the sound of a repetitive tone similar to the thrust reverser warning starts and continues to the end of the recording. At 1137:23 a loud unidentified roaring sound starts and lasts 8 seconds. At 1137:30, loud rumbling noises similar to the aircraft departing the runway start. At 1137:36, a continuous tone similar to landing gear warning signal sounds and continues to the end of the recording. The rumbling noises stop. At 1137:39 the captain states the thrust reversers didn't stow and at 1138:36, the captain states "I went around and the # TRs stayed. The CVR recording ended. Recorded radar data from the FAA Miami Approach Control showed that the flight climbed to 2,200 feet msl after takeoff and turned to a northeasterly heading. Upon reaching the coastline, the flight turned north and paralleled the coast. At this point the flight contacted the FXE local controller and was informed "Hop-a-Jet 55, Executive tower, wind 210 variable 250 at 35, 35 knots and gusting. Winds are uh, heavy on the field. Low level wind shear advisories are in effect. Heavy rains from the west, eastbound and would you like to proceed inbound and land Executive? Say intentions." While on about a 2 mile final approach the local controller transmitted "Hop-a-Jet 55, wind 230 variable 300 at 25 gusts 35. Altimeter 30.00. Runways are wet. Traffic is exiting the runway prior to your arrival, a Dutchess. Caution standing water on runways. Low level wind shear advisories in effect, Runway 31. Cleared to land." At about a ½ mile final the flight is at 300-400 feet at 130 knots groundspeed.

The airplane was last inspected on June 10, 2004, 42 flight hours before the accident, when it received an inspection in accordance with an approved aircraft inspection program (AAIP). The airplane was equipped with Aeronca engine thrust reversers. The airplane was not equipped with a drag chute system. Meteorological Information Post accident review of meteorological information was performed by an NTSB Senior Meteorologist. The National Weather Service (NWS) 1119 Radar Summary Chart depicted a large area of echoes associated with thunderstorms and rain showers extending over Florida. Echoes in the vicinity of the accident range to intense to extreme intensity with movement to the northeast at 26 knots. Review of satellite data shows the 1115, Goes-12 infrared image depicts a large area of low broken clouds over the region with multiple enhanced area identified with convective clouds forming to the east, south through southwest, and west of the Fort Lauderdale area. Towering Cumulus clouds are identified over and west of FLL merging into the enhanced area to the southwest. The 1132, Goes-12 infrared image depicts a rapidly developing cumulonimbus cloud between and over the FLL and FXE airports. The top of the cloud over FXE was in the range of 22,000 feet. The top of the cloud southwest of FXE was in the 39,000 feet range. The 1145, Goes-12 infrared image depicts a developing cumulonimbus cloud over FXE with the cloud top in the 42,000 feet range. Data from the Miami Doppler Weather Radar System for the time of the accident was not available due to technical problems with the system. Data was obtained from the Melbourne, Florida Doppler Weather Radar System, located 118 miles north-northwest of the accident site. The data showed that at FXE, between 1130 and 1145, a VIP Level 1 to 2 echo evolved into a VIP Level 5 "intense" echo at 1135 and a VIP Level 6 "extreme" echo by 1145. Recorded lightning data indicated that between 1137 and 1147, in the area of FXE, there were a total of 64 cloud-to-ground lightning strikes within 15 miles of the airport. In the 5 minutes before the accident there were 15 strikes, all south of the airport. Lightning activity peaked at 1137 with 12 strikes during the 1 minute period. The flight crew reported they obtained weather information from a weather briefing service at Hop-a-Jet's FXE facility and at National Jets at FLL prior to the flight. The CVR shows that ATC also issued current weather information to the flight crew. Communications There were no reported problems with communications between the flight crew of N55LF and FAA Air Traffic Controllers. Airport Information Fort Lauderdale Executive Airport is located approximately 5 miles north of the City of Fort Lauderdale, at an elevation of 14 feet msl. The airport is owned and operated by the City of Fort Lauderdale. Fort Lauderdale Executive Airport has two asphalt runways, 08/26 and 13/31. Runway 08/26 is 6,000 feet long and 100 feet wide. Runway 13/31 is 4,000 feet long and 100 feet wide, and is not grooved. At the time of the accident runway 08/26 was closed for repairs. From the approach end of runway 31 to taxiway "C" the distance is 1,100 feet. Flight Recorders The airplane was equipped with a Universal CVR-30, thirty minute, digital CVR, serial number 6502. The CVR was taken to the NTSB Vehicle Recorders Division, Washington, D.C., where the Cockpit Voice Recorder Group convened on August 11, 2004. A transcript was prepared of the entire 30:04 minute recording. Wreckage and Impact Information The airplane traveled past the departure end of runway 31, passing a section of grass and gravel area before crossing taxiway F. Indications of the nose and main gear shearing off from the fuselage at that point were evident due to the step up to the taxiway from the grass area. The fuselage slid the remaining way on its belly and knocked down a chain link fence protecting a wild life preserve area for ground owls and turtles. The fuselage came to stop in a nose-high attitude on a sand embankment on the northwest side of a ditch, about 1,000 feet past the departure end of runway 31. Examination of the airplane at the accident site after the accident was performed by an FAA inspector. The engine thrust levers were in idle. The engine thrust reverser doors were found in the fully deployed position. The engine fire handles were activated. The fuel quantity gauge read 1,200 pounds and the fuel used counter read 291 pounds. The left altimeter was set to 30.00 inches hg. The first officer's altimeter was set to 29.92 inches hg. The wing flaps were in the 8-degree extended position. Medical and Pathological Information The captain and first officer reported no injuries. No post accident drug testing was performed on the pilots. Tests and Research The airplane flight manual states that the thrust reverser system is activated by the circuit breakers for the thrust reverser lights and thrust reverser emergency stow in. The aircraft must be on the ground and the squat switches in the ground mode. The normal-emergency stow switch must be in the normal position. Both engine thrust levers must be at idle. When these conditions are met the thrust reverse levers can be pulled to the reverse idle/deploy position. An unlock light will illuminate for each reverser followed by a deploy light when the thrust reverser is fully deployed. When both thrust reversers are fully deployed the throttle lock will release and reverse thrust may be increased. To perform a normal stow of the thrust reversers, the thrust reverser levers are returned to the reverse idle/deploy position and then pushed to the stow position. The unlock lights will illuminate and when each thrust reverser is fully stowed the unlock light will go out. The captain stated after the accident that he learned from maintenance personnel that it takes several seconds for the thrust reversers to stow when the levers a
The flight crew's decision to continue the approach into known area of potentially severe weather (Thunderstorm), which resulted in the flight encountering a 30 knot cross wind, heavy rain, low-level wind shear, and hydroplaning on a ungrooved contaminated runway.
