Circumstances:
Aircraft was performing flight MNT107 to Plymouth, on the close Island of Montserrat. Shortly after take off from Saint-Johns runway 07, while climbing, aircraft nosed down, hit violently the runway surface and came to rest. Two passengers were killed instantly while the pilot and another passenger were seriously injured. Pilot died from his injuries few hours later. Right engine was not producing power at the time of impact, and the fuel system feeding that engine contained significant quantities of water. The right-hand fuel filler cap was of a design that was incompatible with the filler neck. Aircraft was parked outside on apron while it was raining about 40 mm of water prior to the accident. It appears that a certain quantity of water penetrated into the tank because the filler cap was not fitted, causing the right engine to stop right after rotation. At the time of impact, right engine was not running while the propeller was not feathered.
Probable cause:
The investigation identified the following causal factors:
1. Significant rainfall, and anomalies in the aircraft’s fuel filler neck and cap, led to the presence of water in the right-hand fuel tank,
2. Shortly after takeoff, the water in the right-hand fuel tank entered the engine fuel system causing the engine to stop running,
3. Control of the aircraft was not retained after the right-hand engine stopped.
