Circumstances:
The commercial pilot of the multiengine airplane was the first of a flight of two airplanes to depart on the cross-country flight, most of which was over the Atlantic Ocean. The pilot of the second airplane stated that he and the accident pilot reviewed the weather for the route and the destination before departing; however, there was no record of the accident pilot receiving an official weather briefing and the information the pilots accessed before the flight could not be determined. The second pilot departed and contacted air traffic control, which advised him of thunderstorms near the destination; he subsequently altered his route of flight and landed uneventfully at the destination. The second pilot stated that he did not hear the accident pilot on the en route air traffic control frequency. Two inflight weather advisories were issued for the route and the area of the destination about 42 and 15 minutes before the accident flight departed, respectively, and warned of heavy to extreme precipitation associated with thunderstorms. It could not be determined whether the accident pilot received these advisories. Review of air traffic control communications and radar data revealed that, about 5 miles from the destination airport, the pilot of the accident airplane reported to the tower controller that he was flying at 700 ft and "coming in below" the thunderstorm. There were no further communications from the pilot. The airplane's last radar target indicated 532 ft about 2 miles south of the shoreline. The airplane was found in about 50 ft of water and was fragmented in several pieces. Postaccident examination revealed no preimpact anomalies with the airplane or engines that would have precluded normal operation. A local resident about 1/2 mile from the accident site took several photos of the approaching thunderstorm, which documented a shelf cloud and cumulus mammatus clouds along the leading edge of the storm, indicative of potential severe turbulence. Review of weather imagery and the airplane's flight path showed that the airplane entered the leading edge of "extreme" intensity echoes with tops near 48,000 ft. Imagery also depicted heavy to extreme intensity radar echoes over the accident site extending to the destination airport. It is likely that the pilot encountered gusting winds, turbulence, restricted visibility in heavy rain, and low cloud ceilings in the vicinity of the accident site and experienced an in-flight loss of control at low altitude. Such conditions are conducive to the development of spatial disorientation; however, the reason for the pilot's loss of control could not be determined based on the available information.
Probable cause:
The pilot's decision to fly under a thunderstorm and a subsequent encounter with turbulence and restricted visibility in heavy rain, which resulted in a loss of control.

Circumstances:
The pilot purchased the multiengine airplane about 18 months prior to the accident, and was conducting his first flight in the airplane, as he flew it from Georgia to Massachusetts. While en route, the airplane experienced a failure of the left engine. The airplane began maneuvering near an airport, as its groundspeed decreased from 173 miles per hour (mph) to 90 mph, 13 mph below the minimum single engine control speed. A witness reported that the airplane appeared to be attempting to land, when it banked to the left, and descended to the ground. The airplane impacted on a road, about 3 miles east-southeast of the airport. A 3-inch, by 2.5- inch hole was observed on the top of the left engine crankcase, and streaks of oil were present on the left gear door, left flap, and the left side of the fuselage. The number two connecting rod was fractured and heat distressed. The number 2 piston assembly was seized in the cylinder barrel. The airplane had been operated about 30 hours, during the 6 years prior to the accident, and it had not been flown since its most recent annual inspection, which was performed about 16 months prior to the accident. In addition, both engines were being operated beyond the manufacturer's recommended time between overhaul limits. The pilot did not possess a multiengine airplane rating. He attended an airplane type specific training course about 20 months prior to the accident. At that time, he reported 452 hours of total flight experience, with 0 hours of multiengine flight experience.
Probable cause:
The pilot's failure to maintain airspeed, while maneuvering with the left engine inoperative. Contributing to the accident were the failure of the left engine, and the pilot's lack of multiengine certification.

Circumstances:
After about a 20 minute flight, while on final approach for landing, the airplane experienced a loss of engine power on both engines, and the pilot-in-command (PIC) performed a forced landing into trees about 1/2 mile from the airport. The left and right boost pumps and the left and right transfer pumps, were observed in the "OFF" position. According to the PIC, after he exited the airplane, he returned to the cockpit and "shut off the fuel panel. The fuel quantity indicator toggle switch was observed in the "TOTAL" position. Examination of the fuel system revealed both engine nacelle tanks, both wing center section tanks, and the right wing fuel tanks were not compromised. About 1 quart of fuel was drained from the left and right engine nacelle tanks, respectively. Less than a quart of fuel was drained from the right wing tanks. The left wing tanks were compromised during the accident; however there was and no evidence of a fuel spill. Examination of the left and right wing center tanks revealed approximately 27 gallons (approximately 181 lbs) of fuel present in each tank. Battery power was connected to the airplane, and when the fuel transfer pump switches were turned to the "ON" position, fuel was observed being pumped from the left and right wing center tanks to their respective nacelle tanks. The accident flight was the third flight of the day for the flight crew and airplane. According to a flight log located in the cockpit, the flight crew indicated 750 lbs of fuel remained at the time of the takeoff. According to the airplane flight manual (AFM),"Fuel for each engine is supplied from a nacelle tank and four interconnected wing tanks...The outboard wing tanks supply the center section wing tank by gravity flow. The nacelle tank draws its fuel supply from the center section tank. Since the center section tank is lower than the other wing tanks and the nacelle tank, the fuel is transferred to the nacelle tank by the fuel transfer pump in the low spot of the center section tank...." Additionally, with the transfer pumps inoperative, all wing fuel except 28 gallons from each wing will transfer to the nacelle tank through gravity feed.
Probable cause:
The pilot’s failure to activate the fuel transfer pumps in accordance with the checklist, which resulted in fuel exhaustion.

Circumstances:
The crew was approaching East Hampton Airport and encountered marginal weather conditions with limited visibility to 3/4 of mile due to the night and ground fog. While in a missed approach configuration, the crew lost control of the airplane that stalled and crashed few miles from the airfield. Both occupants were injured and the aircraft was destroyed.
Probable cause:
Stall during a missed approach after the crew failed to maintain flying speed. The following contributing factors were reported:
- Fog,
- Sky obscured,
- Visibility 3/4 mile or less,
- Pilot transitioned from visual reference to instrument reference,
- Encountered ground fog after MDA.
