Agreed that the plane stalled. No indication the engine quit. The stall likely occurred when he tried to correct his approach too late by cutting back his throttle. As the flight instructor quoted in the article stated, he then failed to increase his throttle to regain control. Had he done so, he might have been able to abort the landing and go around for a new approach.

Instead, it seems he remained focused on continuing with the landing and ultimately ran out of choices. It's always a concern when landing on short, steep strips with added hazards, such as St. Barth's and Saba. You have to have firmly in your mind when and what you are going to do if the approach goes wrong, long before you even start. PJIA has some of the same issues, albeit with a longer runway, but also bigger aircraft.

In any case, it's fortunate that everyone was able to walk away unscathed. 👍
