Training

The crew departed Harare Airport for a local night training flight. Shortly after takeoff, the twin engine aircraft lost height and crashed. Both pilots were killed.

The purpose of the flight was for the flight instructor to provide multiengine airplane training, in a late 1930's vintage amphibious airplane, to his brother, a single engine airplane rated private pilot. No published performance data was available for the airplane, and according to the flight instructor, much of what he knew about the performance of the airplane he learned from previous flights. Just after takeoff on the accident flight, and about 600 feet above ground level (agl), and as the pilot was retracting the landing gear and starting a left turn to the crosswind leg of the traffic pattern, the flight instructor retarded the right throttle in order to simulate a failure of the right engine. The pilot executed the procedures for an in-flight engine failure and the instructor looked out of the window to check for traffic in the airport traffic pattern. The flight instructor then heard the pilot state "I am at blue line but losing altitude." The flight instructor continued to scan for traffic and moved the right throttle forward to about the "half throttle" position. The pilot could not recall if he had adjusted either of the power controls after the initial application of power for takeoff. The airplane continued to descend, impacted the ground, and caught fire.

The crew departed Montpellier-Méditerranée Airport at 0802LT for a local training flight with TRI, one TRE and one pilot under supervision. Following a touch and go on runway 31R, the instructor decided to reduce the power on the right engine and to perform a low pass over the runway. Then the aircraft turned to the left, lost height, rolled to the left and crashed in a pond located to the right of the runway. The aircraft was destroyed and all three occupants were killed.

The pilot's father had just purchased the airplane for his daughter, and she was receiving model-specific training from a contract flight instructor. Her former flight instructor was aboard as a passenger. The engines were started and they quit. They were restarted and they quit again. They were started a third time, and the airplane was taxied for takeoff. Shortly after starting the takeoff roll, the pilot reported an unspecified engine problem. The airplane drifted across the median and parallel runway, then rolled abruptly to the right, struck the ground, and cartwheeled. The landing gear was down. Neither propeller was feathered. Disassembly of the right engine and turbocharger revealed no anomalies. Disassembly and examination of the left engine and turbocharger revealed the mixture shaft and throttle valve in the throttle and fuel control assembly were jammed in the idle cutoff and idle rpm positions, respectively. Manifold valve and fuel injector line flow tests produced higher-than-normal pressures, indicative of a flow restriction. Disassembly of the manifold valve revealed the needle valve in the plunger assembly was stuck in the full open position, collapsing the needle valve spring. A scribe was used to free the needle valve, and the manifold valve and fuel injector lines were again flow tested. The result was a lower pressure. Plunger disassembly revealed the threads had been tapped inside the retainer and metal shavings were found between the retainer and spring. The Teledyne Continental Motor (TCM) retainer has no threads. GPS download showed that 2,698 feet had been covered between the start of the takeoff roll and the attainment of rotation speed. Maximum speed attained was 132 mph. Computations indicated distance to clear a 50-foot obstacle was 2,000 feet, distance to clear a 50-foot obstacle (single engine) was 2,600 feet, and accelerate-stop distance was 3,000 feet.

The aircraft was on a base training flight at Kilimanjaro International Airport. At 0410 hrs it was cleared to the local flying area for upper air works, followed by VOR/ILS approaches to runway 09 via NDB KB. 5H-PAC took off and proceeded to the local flying area where the crew members did upper air works for about 30 minutes. According to the commander, these included clean and dirty stalls, level flights at different speeds, 45 degree turns left and right and exercises on unusual attitudes. Subsequent to these they returned to the airport via NDB KB for ILS approach to runway 09. They carried out a missed approach and proceeded to join RH circuits for touch-and-go operations on runway 09. The last operations before the accident was simulated engine failure after take off followed by single engine overshoot, this time using runway 27. This was approved and the commander was reminded that the surface wind was 090 degrees 08 knots. The aircraft turned left and positioned on right base for runway 27. It was subsequently given a landing clearance. The weather at the material time was fine with temperature 23 degrees Celsius. The controller, who was handling the flight, said that the final approach was perfect. The landing gear was down. The aircraft passed the threshold of runway 27 at about 70 feet above the ground and continued to flare on a straight and level attitude with the landing gear retracted. It continued in this attitude for a distance of about one and a half kilometers down the runway subsequent to which it drifted off the runway to the right. The controller asked the pilot to explain his intentions. There was no reply. Instead, the aircraft was observed to yaw violently as it drifted further to the right. Moments later, it impacted the ground on a grass hedge and skidded along the width of taxiway Y before it came to rest. The commander said that he repossessed the controls immediately when the aircraft started yawing but there was no time effect recovery. There was fuel spillage but fire did not break out. The two pilots, who had not put on their shoulder straps, sustained facial injuries.

Following an uneventful passenger flight from Reykjavik to Sauðárkrókur, the crew decided to fly to Siglufjörður Airport to perform a competence control flight for this airfield. On approach in good weather conditions (visibility over 10 km with clouds at 1,500 feet), the captain disconnected the GPWS system to avoid repetitive alarms. After landing on runway 07, he attended to perform a touch-and-go so he increased engine power and took off. During initial climb, the landing gears were raised and the crew made a right hand turn circuit at an altitude of 500 feet. Following a second approach to runway 07, the aircraft landed on its belly and slid for 280 metres before coming to rest. Both pilots evacuated safely while the aircraft was damaged beyond repair.

The pilot and sole occupant of the DHC-2 seaplane, registration C-GJST, serial number 1368, was on his first flight of the season on the Ottawa River at Gatineau, Quebec. This training flight, conducted according to visual flight rules, was to consist of about 12 touch-and-go landings. The aircraft took off at approximately 1300 eastern daylight time, and made several upwind touch-and-go landings in a westerly direction. At approximately 1340 eastern daylight time, the aircraft was seen about 50 feet above the surface of the water proceeding downwind in an easterly
direction, in a nose-down attitude of over 20 degrees. The right float then struck the water and the aircraft tumbled several times, breaking up on impact. Despite the waves and gusting wind on the river, some riverside residents who witnessed the accident attempted a rescue, but the aircraft sank before they could reach it. Even though the pilot was wearing a seat-belt, he sustained head injuries at impact and drowned.

The crew was returning to Miramar NAS following a routine training mission in Grand Junction. On final approach to Miramar NAS by night, the aircraft crashed near the interstate 15, about 2,400 metres short of runway 24R. The aircraft was destroyed and all four occupants were killed. A weather observation taken from the base at 2045LT reported five-mile visibility with light fog or haze, and a cloud ceiling at 800 feet.

One instructor and two pilots under supervision departed Marseille-Marignane Airport on a training flight. Several scooping manoeuvres were completed on the Sainte-Croix Lake located about 85 km northeast of Marseille. While completing a new scooping procedure, the aircraft approached in a high nose attitude and disintegrated upon landing. The main wreckage sank to a depth of 31 metres off Les Salles-sur-Verdon. One pilot was found alive but seriously injured due to hypothermia (the water temperature was 6° C) while both other occupants, Jean Beauvais and Jean-Pierre Laty, were killed.

The crew was completing a local training flight at Madrid-Getafe AFB when the aircraft crashed in unknown circumstances near Parla, about 8 km south of the airbase. The aircraft was destroyed and both pilots were killed.
