This is UNOFFICIAL information, otherwise known as rumor: Sources leaking investigation details confirm that investigation is centered on failure of R2-5 relay and pretty much specifically discard (don't know the reasons) c/b GND CONT being pulled.

It basically just gives the known number of passengers, crew, PAX+cargo+luggage weight, empty plane's weight, weight w/o fuel, fuel's weight, take off weight, fuel expected to have been used in the flight (17.000 lb), expected weight upon landing (124.863 lb) (1 lb=453gr). Besides the 400kg of fresh fish cargo, there was also 1.095kg of textile products (mostly Timberland).
Landing gears on the plane were frequently serviced on the craft. On Aug 9th parts of the lighting system were also serviced, including "lights at the sides of the landing gear". "Inspection lights of both, left and right side, of the main gears found light bulbs out". "Portable flashlight in cabin, also with a blown bulb". "Light at the end of left wing: also blown bulb.".
Other maintenance actions during August: cockpit security door not able to open with key. First aid kid change requested. The list goes on and on ... Nothing seems relevant, though.
