Circumstances:
On Tuesday 10 July 2018, at approximately 1439Z, two crew members and 17 passengers took off on a ZS-BRV aircraft for a scenic flight from Wonderboom Aerodrome (FAWB) destined for Pilanesberg Aerodrome (FAPN) when the accident occurred. During take-off, the left engine caught fire, however, the crew continued with the flight. They declared an emergency by broadcasting ‘MAYDAY’ and requesting to return to the departure aerodrome. The crew turned to the right with the intention of returning to the aerodrome. However, the left engine fire intensified, causing severe damage to the left wing rear spar and left aileron system, resulting in the aircraft losing height and the crew losing control of the aircraft and colliding with power lines, prior to crashing into a factory building. The footage taken by one of the passengers using their cellphone showed flames coming from the front top side of the left engine cowling and exhaust area after take-off. The air traffic control (ATC) on duty at the time of the accident confirmed that the left engine had caught fire during take-off and that the crew had requested clearance to return to the aerodrome. The ATC then activated the crash alarm and the aircraft was prioritized for landing. During the accident sequence that followed, one passenger (engineer) occupying the jump seat in the cockpit was fatally injured and 18 others sustained injuries. The investigation revealed that during take-off, the left engine had caught fire and the crew had continued with the flight without securing the left engine as prescribed in the aircraft flight manual (AFM). The crew had then declared an emergency and attempted to return to the aerodrome, however, they lost control of the aircraft and collided with power lines prior to crashing into a factory building. Owned by Rovos Air (part of the South African Rovos Rail Group), the aircraft was donated to the Dutch Museum Aviodrome based in Lelystad and has to be transferred to Europe with a delivery date on 23 July 2018. For this occasion, the aircraft was repaint with full Martin's Air Charter colorscheme. Part of the convoy program to Europe, the airplane was subject to several test flights, carrying engineers, technicians, pilots and also members of the Aviodrome Museum.
Probable cause:
During take-off, the left engine caught fire and the crew continued with the flight without securing the left engine as prescribed in the aircraft flight manual (AFM). The crew declared an emergency and attempted to return to the aerodrome, however, they lost control of the aircraft and collided with power lines prior to crashing into a factory building. The following contributing factors were reported:
- Pre-existing damage to the cylinder No 13 piston and ring pack deformation and, most probably, the cylinder No 7’s fractured exhaust valve head that were not detected during maintenance of the aircraft,
- Substandard maintenance for failing to conduct compression tests on all cylinders during the scheduled maintenance prior to the accident,
- Misdiagnosis of the left engine manifold pressure defect as it was reported twice prior to the accident,
- The crew not aborting take-off at 50 knots prior to reaching V1; manifold pressure fluctuation was observed by the crew at 50 knots and that should have resulted in an aborted take-off,
- Lack of crew resource management; this was evident as the crew ignored using the emergency checklist to respond to the in-flight left engine fire,
- Lack of recency training for both the PF and PM, as well as the LAME,
- Non-compliance to Civil Aviation Regulations by both the crew and the maintenance organisation.

Circumstances:
On 18 January 2005 at approximately 1340Z, the pilot accompanied by 4 passengers, took off on a private flight from FAWB (Wonderboom Aerodrome) to FAHS (Harrismith aerodrome). However, the pilot advised the FAWB ATC (Wonderboom Air Traffic Controller) that the intended destination was Springs via Delmas. Sometime after 1455Z the aircraft impacted the ground at a high descent rate and high forward speed on a heading of 260˚M in a 15˚ nose-down and 30˚ right-wing low attitude, whilst the nose of the aircraft was facing in a direction of 211˚M, near Cornelia. Partly cloudy weather conditions, with isolated thundershowers prevailed at the time of the accident. Although there were no eyewitnesses to the accident, local inhabitants reported a severe storm in the vicinity of the accident site at the estimated time of the accident. The five occupants were fatally injured and the aircraft destroyed on impact.
Probable cause:
The pilot may have lost control of the aircraft due to adverse weather conditions and entered a spiral whilst descending for landing at Harrismith. According to the official weather report, the most likely weather conditions at the place of the accident were partly cloudy with isolated thundershowers. Although there were no eyewitnesses to the accident, local inhabitants reported a severe storm in the vicinity of the accident site at the estimated time of the accident.

Circumstances:
Final power assurance checks were carried out on the aircraft’s engines on the morning of the accident. The AME (Aircraft Maintenance Engineer) trimmed the elevator-trim tab to the Full Nose UP position in order to reduce the stick forces required to hold the tail down during the engine power checks, but he did not set the elevator trim back to the neutral position on completion of the checks. The AME was requested by the pilot(s) to remove the aileron and elevator external gust locks and the landing gear down lock pins. He left the rudder lock in place, which was later removed by one of the pilots. The pilot(s) did not carry out a pre-flight inspection. At approximately 1646 on 24 August 1998 the DC3TP, registration number ZS-NKK, crashed during take-off from runway 11 at Wonderboom Airport. The PIC (Pilot-in-Command), who did not wear a shoulder harness, sustained fatal injuries and the co-pilot, who did wear a shoulder harness, serious injures. The accident occurred on the first flight after the aircraft had undergone a maintenance inspection, which included power assurance checks of the engines. The co-pilot sat in the left-hand seat and while he started the engines, the PIC attended to the cockpit checklist.
Probable cause:
It would appear that the accident was as a result of the PIC taking-off with the elevator trim set to the full nose-up position. This resulted in the nose of the aircraft pitching up after rotation, causing the pilot to lose control of the aircraft.

Circumstances:
Shortly after a night takeoff from Jamba Airport, while in initial climb, the aircraft rolled to the right, causing the right wing to struck trees. The airplane lost height and crashed near the runway end. All 14 passengers were injured and all three crew members were killed.
Probable cause:
The copilot was the PIC at the time of the accident. It was reported that engine power was reduced shortly after liftoff and the copilot asked the captain to raise the flaps and to switch off the approach light just after rotation. The assumption that the PIC suffered a spatial disorientation at liftoff was not ruled out.
