Italian Investigation Blames LATAM 777-300ER Tail-Strike Accident on Pilot’s 100-Tonne Weight Calculation Error
An ANSV investigation found a LATAM crew’s 100-tonne weight miscalculation caused a Boeing 777-300ER tail-strike at Milan Malpensa. The error set V-speeds 30 knots too low and underpowered engines, forcing a dramatic low climb. The jet dumped 72t of fuel and returned damaged, highlighting how a single arithmetic error can defeat multiple cockpit safeguards.
