Takeoff (climb)

An annual inspection had been completed on the airplane the same day, and on its first flight after the annual inspection, as the airplane was departing from runway 05, at Naples Municipal Airport, witnesses said the engine ceased operating. They also said that the propeller was rotating either slowly or had stopped, and they then observed the airplane enter a steep turn, followed by an abrupt and uncontrolled nose-low descent and subsequent impact with the ground. The airplane came to rest in a nose-low, near vertical position, suspended at its tail section by a fence and some trees along the eastern perimeter of the airport. It had incurred substantial damage and the pilot and two passengers who were onboard the airplane were fatally injured. Postaccident examination of the airframe, flight controls and the engine did not reveal any mechanical failure or malfunction. The flaps were found to have been set to 10 degrees, and the propeller showed little or no evidence of rotation at impact. The FAA Toxicology Laboratory, Oklahoma City, Oklahoma, performed toxicological studies on specimens obtained from the pilot and the results showed that diphenhydramine was found to be present in urine, and 0.139 (ug/ml, ug/g) diphenhydramine was detected in blood. Diphenhydramine, commonly known by the trade name Benadryl, is an over-the-counter antihistamine with sedative side effects, and is commonly used to treat allergy symptoms. Published research (Weiler et. al. Effects of Fexofenadine, Diphenhydramine, and Alcohol on Driving Performance. Annals of Internal Medicine 2000; 132:354-363), has noted the effect of a maximal over the counter dose of diphenhydramine to be worse than the effect of a 0.10% blood alcohol level on certain measures of simulated driving performance. The level of diphenydramine in the blood of the pilot was consistent with recent use of more than a typical maximum single over-the-counter dose of the medication.

Before takeoff from Anholt Airfield, the pilot failed to position the elevator trim in the neutral position. During the takeoff roll, because the elevator trim remained in a 1,5 unit nose down position, the pilot was unable to rotate so he rejected takeoff. A second attempt to takeoff was abandoned few minutes later for the same reason. During a third attempt to take off, with a tailwind component near the limit, the aircraft lifted off when the stall warning alarm sounded. The pilot lowered the nose to gain speed when the right main gear impacted a sand dune. Out of control, the aircraft crash landed and came to rest. All eight occupants evacuated safely while the aircraft was damaged beyond repair.

The four engine aircraft was dispatched at Sardeh Band Airstrip to exfiltrate US Army Special Forces troops. After takeoff, the aircraft encountered difficulties to gain height, stalled and crashed about 4 km from the airfield. Seven people were injured while three others were killed.

The single engine airplane was engaged in a local skydiving flight at Namur-Temploux Airfield, carrying 10 skydivers and one pilot. Shortly after takeoff, while in initial climb, the aircraft stalled from the tail and crashed near the runway end. A passenger was killed while 10 other occupants were seriously injured. The aircraft was destroyed.

Just after liftoff from Lovozero Airstrip, while climbing to a height of 15-20 metres, the engine lost power and white smoke escaped from the bottom of the engine. The aircraft lost height, struck an 8 metres tall tree located 191 metres past the runway end then crashed in a wooded area 58 metres further. All 12 occupants escaped uninjured while the aircraft was damaged beyond repair.

Shortly after takeoff from Breitscheid Airfield, while climbing to a height of about 10-15 metres, the single engine airplane stalled and crashed beside the runway. All nine occupants (eight skydivers and one pilot) were uninjured while the aircraft was damaged beyond repair.

The crew was completing a local post maintenance test flight at Laredo Airport. After several touch-and-goes, the aircraft was in initial climb when the left engine lost power, followed shortly later by the right engine. The crew reduced his altitude and ditched the aircraft in the Casa Blanca Lake, about 50 feet from the shore. All three crew members were evacuated safely while the aircraft sank in six feet of water.

The twin-tubofan airplane overran the runway during an aborted takeoff, impacting two fences before coming to rest. The pilot reported experiencing no anomalies with the airplane during the preflight inspection and taxi portion of the flight. During takeoff roll, at V1 (103 knots), the pilot began to pull aft on the control yoke. The pilot noticed the nose landing gear was not coming off of the runway and at 120 knots, with full aft control input, elected to abort the takeoff. He pulled the power to idle and applied maximum braking. Upon seeing the localizer antennas approaching the airplane at the departure end of the runway, the pilot veered the airplane to the right of centerline. The airplane departed the runway surface and impacted the fences. Post-accident examination of the runway revealed tire skid marks on the runway that led to the airplane's final resting place. The tire skid marks measured 1,765 feet in length. Examination of the wreckage revealed no pre-existing brake system anomalies that would have hindered the airplane's braking capability. Examination of the elevator trim system revealed it was 12 degrees out of trim in the nose down direction. The airplane underwent a Phase B and Phase 1 through 5 inspections approximately 5 months prior to the accident. The manufacturer's inspection manual indicates the elevator system should be examined every Phase 5 inspection. The aircraft's flight manual informs the pilot that the right elevator and trim tab should be inspected during the exterior inspection to ensure the elevator trim tab position matches its indicator.

The aircraft was completing a regular schedule flight from Jos to Lagos with an intermediate stop in Kano. Weather conditions were good but the OAT at the time of the accident was +42° C. Due to construction works (retreatment of the asphalt surface), the longest runway 24/06 was closed to traffic so the crew was departing from runway 23 at Kano-Mallam Aminu Kano Airport which is 2,600 metres long. Due to high temperature and reduced performances, the aircraft used the entire runway length, overran and rolled on a grassy area for few dozen metres before lifting off. During initial climb, the aircraft encountered difficulties to gain sufficient height and to follow a positive rate of climb when it collided with obstacles and crashed in the district of Gwammaja located about 2 km past the end of runway 23. The aircraft was totally destroyed by impact forces and a post crash fire as well a several buildings, among them a school and a mosque. Among the 77 people on board the aircraft, six survived (five passengers and one stewardess). All 71 other occupants were killed as well as 78 people on the ground. More than 70 other people on the ground were injured, some seriously. It was later reported that the aircraft was out of service for 52 days due to engine problems. Nevertheless, both engines were changed few days prior to the accident and accumulated 10 hours of flight since.

The airplane impacted the terrain following a loss of control during a takeoff initial climb. A witness stated the airplane was noisier than what he is used to hearing. This witness reported the airplane was in a steep left bank in a level pitch attitude. The airplane then began to descent rapidly as it turned to a northerly heading. The witness reported the airplane then seemed to enter a right bank prior to impacting the ground. Another witness reported what sounded like an engine backfire. The pilot reported the airplane lost power. Torsional twisting was visible on the propeller blades following the accident. Following the accident, the undamaged emergency exit from the airplane was found next to the runway. The latching mechanism on the exit was not damaged and the pins were not found with the exit. It was reported that the airplane had sat on the ramp at the departure airport for at least 15 years without being flown. Although the registration for the airplane had not been changed, the pilot reportedly purchased it shortly before the accident. The pilot did not hold a multi-engine rating.
