It looks as the machine had range extender so 91USG full fuel. 91:28 = 3hr and 15 min
That calculation is about right. His estimate for LAG was not accurate despite using a GPS and he told Lagos tower that he had 1 hour of fuel.
Direct line from NAF to Lagos is approx 250nm on a NW track and with a headwind component (westerly to North westerly wind typical for this time of year). Inadequate planning and fuel calculations. Nig regs dictate a VFR fuel reserve of 30 mins (14-15 gals). From a planning standpoint this flight would have been flown intentionally well into VFR reserves with no contingency, and only then with a topped off tank.
