Airport (less than 10 km from airport)

After touchdown on wet runway 24 at Summerville Airport, the airplane is believed to have hydroplaned. Unable to stop within the remaining distance (runway 24 is 5,000 feet long), it overran and came to rest against a berm, bursting into flames. All five occupants evacuated safely while the airplane was destroyed by a post crash fire.

On the day of the occurrence, six Learjet flight crews of the operator involved planned to take off almost at the same time from Hohn Military Airport to different missions. The airplane involved was the third to take off. Two pilots were on board of the Learjet 35A. The Pilot Flying (PF) sat in the left-hand seat and the Pilot Monitoring (PM) in the right. It was planned to fly from Hohn to Wunstorf Military Airport and conduct several instrument approaches for training purposes of the local air traffic control personnel. At the same time, the flight was to be used as proficiency check for the pilot in the left-hand seat for his type and instrument rating for Learjet 20/30. According to the Cockpit Voice Recorder (CVR) recording, the pilots completed the Before Starting Engine checklist prior to starting the engines. A Yaw Damper check and a so-called Full Travel check of the flight controls were performed, among other things. At 1224 hrs, the right engine was started; at 1226 hrs, the left. At 1237 hrs, while still on taxiway C3, the take-off emergency briefing was performed with the words: „[…] when airborn keine [no] Items ausser [except] gear below 500 ft, continue climb, in real life accelerate to V2 plus 30, Klappen [flaps] rein, slight climb weiter auf [to] […]“. At 1238 hrs, another Learjet received take-off clearance with simulated engine failure from the Tower. That flight crew asked over the radio if the single engine take-off was approved and the Tower once again acknowledged it. After the take-off of that Learjet, the flight crew taxied with the airplane involved on the runway to Ramp 1, turned and waited for the clearance to line up on runway 26. At 1244 hrs, the flight crew received the instruction to roll on to runway 26 and wait. They completed the Line-up check and the Before Take-off check. They planned to take-off with flaps 8° and engine full thrust with N1 of 96.6%. After they had received take-off clearance at about 1247 hrs, the airplane accelerated and took off at 1247:34 hrs, according to witnesses in the area of taxiway C3, and entered climb. According to the CVR recording, after take-off the PF instructed the PM to retract the landing gear and engage the Yaw Damper. At 1247:39 hrs, the PM responded with: “Vorab verlierst du simuliert das rechte Triebwerk (in advance, you will lose the right engine)“, the PF acknowledged it by saying: “Copy, gear up“. Then the thrust of the right engine reduced, the left engine maintained the set take-off thrust. At that time, indicated speed was about 160 kt, according to the FDR. At 1247:44 hrs, the PF instructed: “Damper on”. At 1247:45 hrs, the PM answered “Jawohl (yes)”, almost at the same time the PF said quietly: “Oh shit“. At 1247:44 hrs, the PF called out loud several times: “Fuck” and at 1247:54 hrs the PM several times “Shit”. At 1247:55 hrs, the last recording was the landing gear warning generated by the airplane: “Too low“. From the PM’s announcement about the simulated engine failure at 1247:39 hrs until the impact, Hohn Tower transmitted traffic information regarding two Tornado aircraft in the vicinity and instructed the frequency change to Hohn Radar. Witnesses observed that the airplane performed a sort of snap roll and then crashed to the ground at the end of the runway. On impact, an explosive fireball occurred. The pilots suffered fatal injuries and the airplane was destroyed.

Shortly after takeoff from Kampala-Kajjansi Airport, the crew encountered technical issues and elected to return for an emergency landing. Upon touchdown, the single engine airplane went out of control, lost its left wing and engine before coming to rest upside down in a grassy area. Both pilots were rescued, the copilot was slightly injured and the captain was seriously injured. The crew departed Kajjansi Airfield on a positioning flight to Mweya to pick up passengers to Entebbe.

The airplane departed Jakarta-Halim Perdanakusuma Airport on a charter flight to Maleo, carrying four passengers and four crew members. Following an uneventful flight at FL390, the crew started the descent to Maleo-Morowali Airport Runway 23. After touchdown, the airplane was unable to stop within the remaining distance, overran, rolled for about 200 metres and came to rest against a wooded hill. All eight occupants evacuated safely, among them four Chinese passengers. The crew consisted of two pilots, one stewardess and one technician. Runway 05/23 at Maleo Airport is 1,000 metres long. It is believed that the airplane was operated by Lionair Charter Division.

The pilot departed Whitehorse-Erik Nielsen Airport Runway 32L on a positioning flight to Yellowknife. Shortly after takeoff, he declared an emergency and attempted to return. On short final, he lost control of the airplane that crashed within the airport boundary. The pilot was seriously injured and the airplane was destroyed.

On approach to Flores-Mundo Maya Airport, the crew completed the pre-landing checklist and after the landing gear were selected down, the crew did not receive a down and locked indication. In agreement with ATC, the crew performed two low passes over the airport and ATC confirmed that the landing gear were down and did not notice any abnormalities. After this sequence, the crew decided to land. After touchdown, the right main gear collapsed. The airplane veered off runway and came to rest. All 17 occupants evacuated safely.

The flight crew of the business jet reported that after touching down on runway centerline the airplane was struck by a gust of wind from the right. They were able to keep the airplane on the runway centerline but were subsequently struck by another more powerful gust, which pushed the airplane off the left side of the runway. The runway excursion resulted in substantial damage to the fuselage and left wing. A posaccident review of weather radar data showed that a severe thunderstorm (for which a tornado warning had been issued) was present to the west of the airport and was rapidly moving east. There was a convective SIGMET valid for the airport at the time of the accident. The pilot-in-command reported checking relevant weather information before the flight, that the airplane was equipped with an operational onboard weather radar system, and that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Shortly after takeoff from Saint Augustine Airport, while in initial climb, the airplane contacted trees and crashed in a wooded area, bursting into flames. Both occupants and their dog escaped with minor injuries. The airplane was destroyed by a post crash fire.

The pilot reported that while enroute, a low fuel level annunciation occurred. The pilot subsequently prepared to divert to a nearby airport due to low fuel. Within 2 minutes the left engine shut down, followed by the right. The pilot asked air traffic control for vectors to the nearest airport. The sky conditions were clear with no moon, no horizon and no terrain feature visible. While approaching the airport at approximately 2,000 feet above the runway, the airport runway lighting turned off. The pilot was unable to turn the lights back on and subsequently used the terminal and ramp lights to maneuver the airplane to the runway. The airplane touched down and veered off the runway, which resulted in substantial damage to the fuselage. The pilot reported to a first responder that there were no pre accident mechanical failures or malfunctions with the airplane that would have precluded normal operation and that he ran out of gas.

The airplane sustained substantial damage when it was involved in an accident near Thedford, Nebraska. The pilot and passenger were uninjured. The airplane was being operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot reported that during landing, when the nose wheel made contact with the runway, the airplane began to veer right. He attempted to use left rudder and brake to keep the airplane on the runway, but as the airspeed decreased, directional control became harder to maintain and the airplane subsequently departed the right side of the runway. During the runway excursion, the airplane impacted a runway light, spun left and the landing gear collapsed. During a post accident examination, it was determined that the airplane sustained substantial damage to the left wing.
