Circumstances:
The aircraft experienced a loss of engine power and landed in a field after takeoff from Baton Rouge Metropolitan Airport (BTR), Baton Rouge, Louisiana. The commercial pilot and one passenger were not injured and the airplane sustained substantial damage. The airplane was registered to and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91 as a maintenance test flight. Visual meteorological conditions prevailed at the time of the accident and no flight plan had been filed. The local flight was departing at the time of the accident. A review of the air traffic control recording revealed that the pilot requested to takeoff from runway 31 and fly one time around the traffic pattern for a maintenance check. The air traffic controller stated that the airplane dropped below the tree line after takeoff and was unable to reach the pilot on the radio. After the accident the pilot stated that he completed a preflight inspection about 1400, then boarded the airplane and started both engines. While holding short of runway 31, he performed a pre-takeoff check of the airplane including a run-up for each engine with no anomalies noted. During the takeoff roll he advanced the throttles to takeoff power, then rotated. Shortly after rotation he noticed the right engine was not producing full power and the engine speed was decreasing. With no remaining runway available to land, he continued and looked for an off field landing location. He retracted the landing gear and feathered the right propeller. The airplane was unable to maintain altitude so the pilot made a hard forced landing to a grass covered field (figure 1) about 1 mile northwest of the departure end of runway 31.

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:
While conducting a post maintenance test flight in visual flight rules conditions, the private pilot of the multi-engine airplane reported an oil leak to air traffic control. The controller provided vectors for the pilot to enter a right base leg for a landing to the south at the nearest airport, about 7 miles away. The pilot turned toward the airport but indicated that he did not have the airport in sight. Further, while maneuvering toward the airport, the pilot reported that the engine was "dead," and he still did not see the airport. The final radar data point recorded the airplane's position about 3.5 miles west-northwest of the approach end of the runway; the wreckage site was located about 4 miles northeast of the runway, indicating that the pilot flew past the airport rather than turning onto a final approach for landing. The reason that the pilot did not see the runway during the approach to the alternate airport, given that the airplane was operating in visual conditions and the controller was issuing guidance information, could not be determined. Regardless, the pilot did not execute a precautionary landing in a timely manner and lost control of the airplane. Examination of the airplane's left engine revealed that the No. 2 connecting rod was broken. The connecting rod bearings exhibited signs of heat distress and discoloration consistent with a lack of lubrication. The engine's oil pump was intact, and the gears were wet with oil. Based on the available evidence, the engine failure was the result of oil starvation; however, examination could not identify the reason for the starvation.
Probable cause:
The pilot's failure to identify the alternate runway, to perform a timely precautionary landing, and to maintain airplane control. Contributing to the accident was the failure of the left engine due to oil starvation for reasons that could not be determined based on the post accident examination.

Aircraft flight hours:

Circumstances:
The pilot departed on a postmaintenance test flight during day visual meteorological conditions. According to the operator, the purpose of the flight was to break in six recently installed engine cylinders, and the flight was expected to last 3.5 hours. Recorded automatic dependent surveillance-broadcast data showed that the airplane was operating at altitudes of less than 500 ft mean sea level for the majority of the flight. The data ended about 3 hours after takeoff with the airplane located about 23 miles from the accident site. There were no witnesses to the accident, which occurred in a remote area. When the airplane did not return, the operator reported to the Federal Aviation Administration that the airplane was overdue. Searchers subsequently discovered the fragmented wreckage submerged in a swift moving river, about 40 miles southeast of the departure/destination airport. Postmortem toxicology tests identified 21% carboxyhemoglobin (carbon monoxide) in the pilot's blood. The pilot was a nonsmoker, and nonsmokers normally have no more than 3% carboxyhemoglobin. There was no evidence of postimpact fire; therefore, it is likely that the pilot's elevated carboxyhemoglobin level was from acute exposure to carbon monoxide during the 3 hours of flight time before the accident. As the pilot did not notify air traffic control or the operator's home base of any problems during the flight, it is unlikely that he was aware that there was carbon monoxide present. Early symptoms of carbon monoxide exposure may include headache, malaise, nausea, and dizziness. Carboxyhemoglobin levels between 10% and 20% can result in confusion, impaired judgment, and difficulty concentrating. While it is not possible to determine the exact symptoms the pilot experienced, it is likely that the pilot had symptoms that may have been distracting as well as some degree of impairment in his judgment and concentration. Given the low altitudes at which he was operating the airplane, he had little margin for error. Thus, it is likely that the carbon monoxide exposure adversely affected the pilot's performance and contributed to his failure to maintain clearance from the terrain. According to the operator, the airplane had a "winter heat kit" installed, which modified the airplane's original cabin heat system. The modification incorporated an additional exhaust/heat shroud system designed to provide increased cabin heat during wintertime operations. Review of maintenance records revealed that the modification had not been installed in accordance with Federal Aviation Administration field approval procedures. Examination of the recovered wreckage did not reveal evidence of any preexisting mechanical anomalies that would have precluded normal operation of the airplane. Examination of the airplane's right side exhaust/heat exchanger did not reveal any leaks or fractures that would have led to carbon monoxide in the cabin. Because the left side exhaust/heat exchanger was
not recovered, it was not possible to determine whether it was the source of the carbon monoxide.
Probable cause:
The pilot's failure to maintain altitude, which resulted in collision with the terrain. Contributing to the accident was the pilot's impairment from carbon monoxide exposure in flight. The source of the carbon monoxide could not be determined because the wreckage could not be completely recovered.
