Flight

The four engine aircraft Harbin SH-5 (Shuishang Hongzha 5) was engaged in a training mission off Qingdao with a crew of five on board. In unknown circumstances, the seaplane crashed in the Jiaozhou Bay few km offshore, killing all five occupants.

The crew was engaged in a fumigation mission against locusts over plantation located near Jyl-Kol, in the Jalal-Abad Province. While flying at a height of about 15 metres, the aircraft hit power cables and crashed, bursting into flames. All three occupants were killed and aircraft was destroyed by post crash fire.

During a cross-country instrument flight rules (IFR) flight, the air traffic controller cleared the pilot to begin his initial descent for landing and issued a heading change to begin the approach. The pilot acknowledged the altitude and heading change. One minute later, the controller noticed that the airplane's radar track was not tracking the assigned heading. The controller queried the pilot as to his intentions, and the pilot replied that he was in a spin. There were no further communications with the pilot. The wreckage was subsequently located in steep mountainous terrain. A study of the weather indicated widespread cloud cover in the area around the time of the accident. A witness near the accident site reported that he heard an airplane in a dive but could not see it due to the very dark clouds in the area. He heard the engine noise increase and decrease multiple times. It is likely that the pilot entered into the clouds and failed to maintain airplane control. The changes in the engine noise were most likely the result of the pilot's attempt to recover from the spin. About 8 months before the accident, the pilot completed the initial pilot training course in the accident airplane and was signed off for IFR currency; however, recent or current IFR experience could not be determined. Examination of the fragmented airplane and engines revealed no abnormalities that would have precluded normal operation.

The pilot, sole on board, was performing a crop spraying flight on behalf of the 'Svoboda' Agricultural Cooperation in the region of Chernolesskoye. While flying at a height of about 9 metres, trying to get altitude, the single engine aircraft successively collided with power cables and a concrete pylon, continued for about 99 metres then crashed in an open field, bursting into flames. The aircraft was destroyed by impact forces and a post impact fire and the pilot was killed.

The single engine aircraft departed Balota (Drobeta) Aerodrome at 0930LT on a spraying mission over wooded area on behalf of the Department of Forestry, carrying one passenger and two pilots. About 50 minutes into the flight, after it completed several low passes over the area to be treated, the engine lost power. The crew decided to return to Balota Aerodrome and completed a 180 turn when the engine stopped. The crew attempted an emergency landing in an open field. After landing, the aircraft rolled for about 130 metres when the left main gear collapsed and the airplane came to rest. All three occupants escaped uninjured and the aircraft was damaged beyond repair.

On 3 May 2013, at approximately 1448 hours local time (L), a KC-135R, tail number 63-8877, assigned to the 22d Expeditionary Air Refueling Squadron, 376th Air Expeditionary Wing, Transit Center at Manas, Kyrgyz Republic, crashed in the foothills of mountains located 6 miles south of Chaldovar, Kyrgyz Republic. The mishap crew (MC), which consisted of the mishap pilot (MP), mishap co-pilot (MCP), and mishap boom operator (MBO), perished during the accident. The mishap aircraft (MA) exploded inflight, impacted the terrain at three main locations, and burned. The MA was completely destroyed with total loss to government property estimated at $66.3 million. Upon impact, approximately 228 cubic meters of soil were contaminated with jet fuel, and three distinct craters containing a burn pattern were created. The MA’s mission was to refuel coalition aircraft in Afghanistan and then return to the Transit Center at Manas. Immediately after takeoff, the MA experienced an unexpected rapid heading change from the direction of flight known as a crab. During climb, nearly continuous rudder hunting caused the MA’s nose to hunt slowly left and right about one degree in both directions. The MP commented on the lateral control challenges and possible series yaw damper (SYD) malfunction but continued the mission without turning off either the SYD or rudder power. Approximately nine minutes into the flight, the MA began a series of increasing yaw and roll oscillations known as a dutch roll, which was undiagnosed by the MC. The MCP attempted to decrease these oscillations using manual aileron controls, as well as two brief attempts with the autopilot. The manual corrective inputs kept the oscillations from growing. The autopilot use further exacerbated the situation, and the oscillations intensified. After the second autopilot use, the MP assumed control of the MA and used left rudder to start a left turn. A subsequent series of alternating small rudder inputs, caused by the MA’s dutch roll-induced acceleration forces varying the MP’s foot pressure on the rudder pedals, sharply increased the dutch roll oscillations. Within 30 seconds, the MP made a right rudder input to roll out of the turn, exacerbating the dutch roll condition. The cumulative effects of the malfunctioning SYD, coupled with autopilot use and rudder movements during the unrecognized dutch roll, generated dutch roll forces that exceeded the MA’s design structural limits. The tail section failed and separated from the aircraft, causing the MA to pitch down sharply, enter into a high-speed dive, explode inflight and subsequently impact the ground at approximately 1448L.

Michael B. Braunstein, aged 72, was the owner of this vintage aircraft built in 1943 and was performing a local flight within the State of New York. Aircraft was destroyed when it impacted the waters of the Hudson River, near Catskill, New York. The certificated airline transport pilot was fatally injured. Visual meteorological conditions prevailed, and no flight plan had been filed for the local personal flight conducted under Title 14 Code of Federal Regulations Part 91, which departed from B Flat Farm Airport (3NK8), Copake, New York about 1600. Approximately 25 witnesses were interviewed. Witnesses reported observing the twin-engine amphibious airplane flying southbound low above a river and hearing the engine running. The airplane then made a 180-degree left turn, which was consistent with the pilot flying a tight traffic pattern before attempting a water landing. The airplane then descended, leveled off above the water, and suddenly banked left. The airplane’s nose and left pontoon then struck the water, and the airplane nosed over, caught fire, and sank. Postrecovery examination of the wreckage revealed that the landing gear was in the “up” position and that the flaps were extended, which indicates that the airplane had been configured for a water landing. No evidence of any preimpact failures or malfunctions of the airplane or engines was found that would have precluded normal operation. At the time of the accident, a light breeze was blowing, the river was at slack tide, and the water conditions were calm, all of which were conducive to glassy water conditions. It is likely that the glassy water conditions adversely affected the pilot’s depth perception and led to his inability to correctly judge the airplane’s height above the water. He subsequently flared the airplane too high, which resulted in the airplane exceeding its critical angle-of-attack, entering an aerodynamic stall, and impacting the water in a nose-low attitude.

On 27 April 2013, at approximately 1243 local time (L) in Afghanistan, an MC-12W, tail number 09-0676 impacted terrain 110 nautical miles northeast of Kandahar Airfield (KAF) while on a combat intelligence, surveillance, and reconnaissance (ISR) mission. The four crewmembers on board were the Mishap Mission Commander (MMC), Mishap Pilot (MP), Mishap Sensor Operator (MSO), and Mishap Tactical Systems Operator (MTSO). The four airmen were killed instantly on impact and the Mishap Aircraft (MA), valued at $19.8 million, was destroyed. The crew and MA were deployed to the 361st expeditionary Reconnaissance Squadron, 451st Air Expeditionary Wing, KAF, Afghanistan. The MA, callsign Independence 08, departed KAF at 1157L and entered orbit at 1229L. The MA encountered deteriorating weather in the orbit and was climbing from 20,000 to 23,000 feet mean sea level (MSL) at 1241L to fly above the weather when the mishap occurred. In addition, the crew had found an enemy combatant and was in the process of adjusting their orbit to enhance mission success.

The pilot and two passengers departed Sarlat-Domme Airport for a training mission over the region of Bordeaux. A precision approach was completed at Bordeaux-Mérignac Airport followed by a go-around procedure. The IFR flight plan was closed and the pilot continued under VFR mode to Bordeaux-Léognan-Saucats Aerodrome where he landed. A passenger deplaned, the engine remained running and the aircraft took off few minutes later to Bergerac where a refueling was planned. Approximately 10 minutes after takeoff, while cruising at an altitude of 2,000 feet, both engines failed. The pilot reduced his altitude, selected gear down and attempted and emergency landing in a vineyard. Upon landing, the undercarriage were torn off and the aircraft slid for few dozen metres before coming to rest. Both occupants escaped uninjured and the aircraft was damaged beyond repair.

The crew was completing a local training flight at Santa Lucía AFB when the single engine aircraft crashed in unknown circumstances in an open field near the airfield. The aircraft was destroyed and both occupants were killed.
