Circumstances:
The airplane departed Nassau-Lynden Pindling Airport at 1113LT back to Opa Locka in Miami after delivering various goods. At 1203LT, while cruising at an altitude of 4,300 feet in good weather conditions, the crew declared an emergency and informed ATC about a double engine failure. The crew elected to ditch the aircraft that crashed into the sea 12 minutes later about 13 miles east of the Bay Harbor Islands. Coast Guards were quickly dispatched on the scene and the copilot aged 28 was able to climb by himself in the rescue basket and to be airlifted to hospital. Unfortunately, the captain aged 68 died. On Feb 22nd 2019 the NTSB released a preliminary report stating the crew had departed Opa Locka for Nassau with 900 gallons of fuel on board but experienced trouble with the left hand propeller control enroute to Nassau when the propeller became stuck at 2,400 rpm. The crew was unable to reset the propeller control. A message sent to maintenance did not transmit. The captain decided that they wouldn't start up for the return flight, if the propeller control had not reset they'd shut down again and wait for maintenance. Both engines and propellers came up normally however and they departed for Opa Locka. Climbing through 4,000 feet the left hand propeller became again stuck at 2,400 rpm. The captain managed to bump the propeller up to 2,700 rpm, equalized power on both engines, levelled off at 4,500 feet, cancelled the IFR flight plan and continued visually to Opa Locka. The flight was uneventful until they began the descent to 1,500 feet. At that point the right hand engine "backfired" and surged. The crew shut the engine down. A short time later the left hand engine also backfired and surged. The captain continued flying the aircraft while the first officer worked the related checklists, however, when they were getting too low and it became clear they had to ditch the captain instructed to declare Mayday and brace for impact.

Circumstances:
Witnesses observed the aircraft departing from runway 14 with a rolling start. They said the aircraft rotated at the departure end of the runway and remained in ground effect with an excessive, nose high attitude. It then struck the airport perimeter fence, a barrier wall, and power lines. Power line wires were dragged through a residential area, resulting in additional damage. The airplane then crashed in a pasture and burned. Investigation revealed the airplane had been loaded to a gross weight (GW) of 50,870 lbs. Its maximum GW was limited to 48,000 lbs at sea level with the use of antidetonation injection (ADI) fluid and 40,900 lbs without ADI. Density altitude at the airport was 6200 feet. For conditions at the airport, maximum GW for takeoff with ADI and 15° of flaps was 43,205 lbs; without ADI and with 13 degrees of flaps, maximum GW was 38,909 lbs. The airplane flaps were found in the retracted position, but there was no performance data for takeoff with the flaps retracted. No ADI fluid was found in the line to the right engine, although it was intact; the ADI tank was destroyed; the ADI line to the left engine was damaged. The airplane was being flown under provision of a ferry permit, which did not provide for the cargo or the two passengers that were aboard. The first pilot (PIC) had accrued about 8 hours of flight experience in the make and model of airplane.
Probable cause:
Inadequate preflight planning and preparation by the first pilot (PIC), his failure to ensure the aircraft was properly loaded within limitations, his failure to use proper flaps for takeoff, his failure to use ADI assisted takeoff, and his resultant failure to attain sufficient airspeed to climb after takeoff. Factors relating to the accident were: the high density altitude, and the PIC's lack of experience in the make and model of airplane.
Final Report:

Circumstances:
The crew was completing a local training flight at Corpus Christi Airport. Following an approach in reduced visibility due to foggy conditions, the airplane landed hard on runway 10R. Upon touchdown, the aircraft went out of control, veered off runway and came to rest. All eight crew members evacuated safely while the aircraft was damaged beyond repair.
