Circumstances:
The intention of the flight was to drop eight parachutists from an altitude of 1,500 metres. It was the twelfth and planned to be the last flight of the day. The weather conditions were good. The parachutist bench to the right of the pilot had been replaced with a pilot's seat to distance the parachutists from the pilot as a Covid-19 precautionary measure. The pilot had no ability to perform a mass and balance calculation with the available information. After take-off, the aircraft climbed to an altitude of 400 to 500 feet above ground before changing course 180 degrees to the left. The aircraft turned around quickly in a descending turn with a high bank angle. During the final phase, the aircraft dived steeply and then slightly levelled off before impact. Upon impact, the landing gear was teared off, after which the aircraft skidded on its belly 48 metres straight ahead and caught fire. All nine persons on board sustained fatal injuries.
Probable cause:
Control of the aircraft was likely lost in connection with the wing flaps being retracted in a situation where the stick forces were high due to an abnormal elevator trim position, while the aircraft was unstable due to being tail-heavy and abnormally trimmed. The low altitude was not sufficient to regain control of the aircraft. The cause of the accident was that several safety slips occurred in the operation, which resulted in that the safety margin was too small for a safe flight.

Circumstances:
On the morning of 25 June 2021, the Cessna 208B with registration PH-FST was parked inside the hangar of a maintenance organization. The organization performed maintenance tasks on the aircraft on a regular basis. The maintenance organization had scheduled to perform a maintenance task before the planned flights that day. When the aircraft was on ground with the engine off, erratic and high engine Exhaust Gas Temperature (EGT) readings were reported. The maintenance organization suspected a faulty magnetic pick-up in the engine’s propeller governor to be the cause of these erratic EGT readings. A mechanic under supervision of a licensed engineer was tasked to replace the magnetic pick-up. After removal of the old magnetic pick-up, the mechanic followed steps one through four of the maintenance manual to install the new magnetic pick-up. Steps five through eight, a system voltage test to check correct installation, were not noticed by the mechanic and as a result not carried out. After connecting the wiring and tightening the lock nut, the mechanic, together with the pilot, did a static engine test run and performed the Single Red Line (SRL) check to verify the system and EGT readings. After the system was found to be functioning correctly, the mechanic left the aircraft and the pilot taxied to the skydive organization's building to pick up parachutists. Following the boarding of seventeen parachutists, the pilot taxied to runway 26 and commenced the takeoff roll. Shortly after takeoff, without any warning, the engine lost power at approximately 400 feet above field level. The pilot made an emergency landing in a field whereby the aircraft sustained substantial damage to the fuselage, wings, landing gear and propeller. One parachutist suffered minor injuries.
Probable cause:
During the initial climb after takeoff, the aircraft suffered a complete loss of engine power as a result of the uncommanded feathering of the propeller. This feathering was the result of damage that occurred within the propeller governor. Most probably, the incorrect installation of the magnetic pick-up in the propeller governor prior to the accident flight led to contact damage between the pick-up and the rotating toothed gear. Debris restricted the free movement of the ball head assembly in the governor housing, allowing all oil to drain from the propeller dome and causing the propeller to continuously move to the feather position and eventually cease rotation. The increasing pitch of the propeller led to a power reduction of the engine which reinforced itself. The distorted output signal of the damaged magnetic pick-up did not cause the engine flame out. The design of the propeller governor’s toothed gear makes it possible to position the magnetic pick-up in between its teeth. The maintenance procedure for the replacement of the magnetic pick-up did not specifically mention or address this. The final steps of this procedure, a voltage check to verify the correct placement of the pick-up, were not performed by the maintenance staff. The design of the toothed gear in combination with the procedure in the maintenance manual allowed for the incorrect installation.

Circumstances:
The single engine airplane departed Cremona-Migliaro Airport in the morning on a local skydiving flight, carrying eight skydivers and one pilot. This was the second sortie of the day. Once the altitude of 4,000 metres was reached, all eight skydivers successfully jumped out and the pilot started the descent to return to the airport. While descending to runway 11, the airplane collided with the eighth skydivers that hit the left wing and the vertical stabilizer. A large section of the left wing separated, causing the airplane to enter an uncontrolled descent and to crash in a cornfield located in Livrasco, about two km north of the airport. The pilot and the skydiver were killed. The airplane was totally destroyed.
Probable cause:
The cause of the accident was an in-flight collision between the Pilatus PC-6 descending and a free-falling track-suit parachutist. This collision resulted in a loss of control of the aircraft in flight and the destruction of the left wing of the aircraft, which fell to the ground uncontrolled.
The following factors contributed to the accident:
- Inadequate coordination between pilot and parachutist in relation to their respective descent and drift paths,
- The meteorological conditions at the time of the parachutist's exit from the aircraft, which took place in cloud and in the absence of visual contact with the ground, in a situation, therefore, incompatible with VFR flight rules and ENAC regulations for parachuting,
- The absence of codified procedures at the Italian level, integrating the procedures for jumps with those of aircraft operators used for parachute jumps, including deconfliction between descending aircraft and parachutists performing drift or wingsuit jumps.
The inadequate coordination between the pilot and parachutist in relation to their respective descent and drift paths could also be attributable to the absence of a responsible person to ensure that the above mentioned coordination was in place. In addition to the above mentioned criticalities, the ANSV investigation activity revealed, also in the present case, a general lack of rules and controls regarding parachuting activities carried out outside of training activities, which reasonably contributed to the occurrence of the investigated aircraft accidents.

Circumstances:
At 1448 hrs, the pilot took off from Gransee Special Airfield with the Cessna 208 Caravan to a commercial flight in accordance with visual flight rules. On board were the pilot and 15 skydivers, which were dropped at flight level 130. On this day, the pilot had already conducted three flights dropping skydivers with a total flight time of 48 min. After having dropped the skydivers during the fourth flight, the airplane was last captured by the radar at 1505:49 hrs, during approach to land at the airfield, close to the accident site at about 550 ft AMSL. At the time, ground speed was 168 kt and heading 330°. The Flugleiter stated that he had observed the last phase of the approach. The airplane had been in a left-hand turn with a bank angle of up to 90° close to the ground. He assumed that the pilot might have “overshot” the extended centre line of runway 29 when he entered the final approach coming from the south. Then the airplane had vanished behind the trees. The pilot did not transmit an emergency call. The Flugleiter also stated that with the previous flight he had witnessed a similar manoeuvre. The radar recording of the third flight ended at 1417:54 hrs with a recorded altitude of about 1,400 ft AGL. At the time, ground speed was 168 kt and heading 355°. During both flights the skydivers had been dropped at flight level 130 at a heading of about 300° south of the airfield. After dropping the skydivers, at 1415:07 hrs and at 1502:52 hrs, respectively, the airplane entered a descent with a very high rate of descent and flew in a wide left-hand turn back to the airfield. During the third flight a right-left-hand turn with bank angles of about 50° to 60° occurred during descent.
Probable cause:
The air accident was due to a risky flight manoeuvre close to the ground which resulted in a controlled impact with the ground. The speed during the approach exceeded the operations limitations of the airplane. The approach was not stabilized.
Contributing Human Factors:
- Recurrent acceptance of risky flight manoeuvres close to the ground by the pilot (routine violations),
- Overconfidence and insufficient risk assessment of the pilot.
Contributing Operational Factors:
- Unsuitable wording in the operations manual in regard to approaches after dropping skydivers.

Circumstances:
The purpose of the flight was to drop eight parachutists from flight level 130 (an altitude of 13,000 feet, approximately 4,000 metres). The load sheet that the pilot received did not contain any information about the individual weights of the parachutists or the total mass of the load. The pilot could thus not, with any help from the load sheet, check or make his own calculation of mass and balance before the flight. The aeroplane was approaching the airport and, at 14:05 hrs, the pilot requested permission to drop the parachutists slightly higher because of clouds. The airspeed was decreasing in conjunction with the aeroplane’s approach to the airport. Just over a kilometre from the airport where the jump point was located, the aeroplane suddenly changed direction to the left and began descending rapidly in almost the opposite direction. The aeroplane then travelled just under one kilometre at the same time as it descended 1,500 metres, which is a dive angle of over 45 degrees. The aeroplane broke up in the air as both the airspeed and the g-forces exceeded the permitted values for the aeroplane. From an altitude of 2,000 metres, the aeroplane fell almost vertically with a descent velocity of around 60 m/s. The fact that no one was able to get out and save themselves using their parachute was probably due to the g-forces and the rotations that occurred. All those on board remained in the aeroplane and died immediately upon impact.
Probable cause:
The control of the aeroplane was probably lost due to low airspeed and that the aeroplane was unstable as a result of a tail-heavy aeroplane in combination with the weather conditions, and a heavy workload in relation to the knowledge and experience of the pilot. Limited experience and knowledge of flying without visual references and changes to the centre of gravity in the aeroplane have probably led to it being impossible to regain control of the aeroplane.
The following factors are deemed to be probable causes of the accident:
- The lack of a safe system for risk analyses and operational support, including data for making decisions concerning flights, termination or replanning of commenced flights.
- The lack of a standardised practical and theoretical training programme with approval of a qualified instructor.
- The lack of a safe system for determining centre of gravity prior to and in conjunction with parachuting jumps.

Circumstances:
On June 21, 2019, about 1822 Hawaii-Aleutian standard time, a Beech King Air 65-A90 airplane, N256TA, impacted terrain after takeoff from Dillingham Airfield (HDH), Mokuleia, Hawaii. The pilot and 10 passengers were fatally injured, and the airplane was destroyed. The airplane was owned by N80896 LLC and was operated by Oahu Parachute Center (OPC) LLC under the provisions of Title 14 Code of Federal Regulations (CFR) Part 91 as a local parachute jump (skydiving) flight. Visual meteorological conditions prevailed at the time of the accident. OPC had scheduled five parachute jump flights on the day of the accident and referred to the third through fifth flights of the day as “sunset” flights because they occurred during the late afternoon and early evening. The accident occurred during the fourth flight. The accident pilot was the pilot-in-command (PIC) for each of the OPC flights that departed on the day of the accident. The pilot and 8 of the 10 passengers initially boarded the airplane. These eight passengers comprised three OPC tandem parachute instructors, three passenger parachutists, and two OPC parachutists performing camera operator functions. The pilot began to taxi the airplane from OPC’s location on the airport. According to a witness (an OPC tandem instructor who was not aboard the accident flight), the two other passengers—solo parachutists who had been on the previous skydiving flight and were late additions to the accident flight—“ran out to the airplane and were loaded up at the last minute.” The pilot taxied the airplane to runway 8 about 1820, and the airplane departed about 1822. According to multiple witnesses, after the airplane lifted off, it banked to the left, rolled inverted, and descended to the ground. One witness stated that, before impact, the airplane appeared to be intact and that there were no unusual noises or smoke coming from the airplane. A security camera video showed that the airplane was inverted in a 45° nose-down attitude at the time of impact. The airplane impacted a grass and dirt area about 630 ft northeast of the departure end of the runway, and a postcrash fire ensued. The airplane was not equipped, and was not required to be equipped, with a cockpit voice recorder or a flight data recorder. The accident flight was not detected by radar at the Federal Aviation Administration’s (FAA) Hawaii Control Facility, which was the air traffic control (ATC) facility with jurisdiction of the airspace over HDH. The FAA found no audio communications between the accident airplane and ATC on the day of the accident.
Probable cause:
The National Transportation Safety Board determines that the probable cause of this accident was the pilot’s aggressive takeoff maneuver, which resulted in an accelerated stall and subsequent loss of control at an altitude that was too low for recovery.
Contributing to the accident were
1) the operation of the airplane near its aft center of gravity limit and the pilot’s lack of training and experience with the handling qualities of the airplane in this flight regime;
2) the failure of Oahu Parachute Center and its contract mechanic to maintain the airplane in an airworthy condition and to detect and repair the airplane’s twisted left wing, which reduced the airplane’s stall margin; and
3) the Federal Aviation Administration’s (FAA) insufficient regulatory framework for overseeing parachute jump operations. Contributing to the pilot’s training deficiencies was the FAA’s lack of awareness that the pilot’s flight instructor was providing substandard training.
