An2 tanks full, cabin full means to much aft cg.
Plane will lift off in stall and crash.
Often happens with parachute jumpers.
You have to leave the last seat empty and sit this jumper on the cockpit step.
edit: Just found there were only 4 people on board.
So I take back my comment

Wrong trim tab offset

Happy to have helped. :O
Anybody with AN systems knowledge?
Does a fuel pickup unport with a steep climb and partial fuel load?
Im not convinced this is a straight up stall, this could also be a (partial) power loss followed by an unsuccessful turnback to the runway.

Could be a variety of reasons. I wonder if Juan is hinting near the end that it was an intentionally steep climbout. I believe it was at an aircraft fly-in, a type of event that has a history of occasional showing off aircraft performance.

People in Juan's comments section mentioned a wrong trim setting for takeoff (like using the trim setting left from the landing before) might be enough to stall it on takeoff without one pilot being able to oversteer it by force.
That might very well be the case.

Sounds like the engine was running normally so scratch that option.
Leaves the fly-in show off or elevator trim.

The position of the ailerons, and no obvious rudder deflection, after it passes over, suggests a factor in the loss of control...

A company I worked for in Central Africa operated a couple of An2s. A highly-experienced-on-type South African pilot checked out our crew and also emphasised that the aircraft needed to be loaded correctly as it was prone to aft C of G handling issues. I remember clearly painting the bay load restrictions on both sides of the cabin sidewalls to highlight the limits.
I heard that the same pilot was killed at Rand a couple of years later in an An2, along with two others, when insecure freight shifted aft on take-off and it stalled into power lines.
