The following is based on published news reports and specs. A Cessna 150's gross weight is 1,600 lbs and empty weight is 970 lbs, so useful load is 630 lbs. The distance from Tortola to Guadaloupe is 170 nm (not 220 nm). Range with standard tanks, at 75% power cruise speed, is 300 nm. Fuel capacity without long range tanks is 26 gallons, or about 208 lbs, leaving 422 lbs for pilot (there was no passenger) and gear. Long range tanks would add 10 gallons, or another 80 lbs. If the pilot weighed 200 lbs, then 222 lbs was left for cargo with standard tanks and 142 lbs for cargo with long range tanks. Temperature was 88 F and humidity was 60%. Weight and balance, and density altitude, would not seem to be causative factors.

Some news reports state that there was a "runway overrun." Take off distance for a Cessna 150 at gross weight over a 50 ft obstacle is 1,375 ft. The EIS runway is 4,642 ft. Runway length would not seem to be a causative factor.

Pictures of the damage suggest a stall, i.e. failure to maintain lift, which leaves (1) engine failure, and/or (2) pilot error.
