Despite this, possibly due to their concerns with passenger comfort (the VOR 1 approach would have required performing the "circle to land" maneuver at a relatively low altitude over the airport to land on runway 19), or possibly by simply being late to set up for the recommended VOR 1 approach (the flight time was only about 8 minutes from takeoff at Albany to the Glens Falls area, with a significant tailwind component of approximately 50 knots), the crew did not execute the VOR 1 approach. Instead, the crew appeared to select an improvised and unauthorized modified version of the VOR/DME 19 approach, which included flying outbound followed by a course reversal at about north of the airport, over Lake George. As the crew performed what appeared to be an unpublished and unauthorized procedure turn for course reversal on the VOR/DME 19 approach path, they descended prematurely and hit the side of a mountain. It was subsequently determined that a southerly wind created a downdraft effect which, coupled with the aircraft's low altitude over the terrain, contributed to the crash.
