On 4 December 1980, a chartered aircraft crashed shortly after taking off from Lisbon's Portela Airport, killing Portugal's Prime Minister, Francisco de Sá Carneiro, and Defense Minister Adelino Amaro da Costa. Sá Carneiro had been elected Prime Minister on 3 January 1980, following the 1974 Carnation Revolution, with da Costa serving as the country's first civilian Defense Minister. The two men were traveling to a campaign rally three days ahead of Portugal's 1980 presidential election. Da Costa had chartered the Cessna 421A Golden Eagle for the trip; Sá Carneiro, who had planned to travel separately, joined at the last minute with his partner, Snu Abecassis. Witnesses reported seeing the aircraft trailing debris before it struck high-voltage power lines and crashed in a fireball.
Portugal's aviation authority initially attributed the crash to a lack of fuel in one of the aircraft's tanks, and a 1981 police report ruled out any criminal cause. The Attorney General suspended the inquiry in 1983, and parliamentary investigations in 1990 and 1991 did not reopen the case. A fifth parliamentary inquiry in 1995 prompted a judicial reopening: the victims' bodies were exhumed, and a forensic report concluded that an in-flight explosion had probably not occurred, though it did not rule out the possibility.
A private prosecution brought by the victims' relatives was declared time-barred in 1996, except for the case against one alleged conspirator, whose statute of limitations was suspended because he was separately detained in Brazil. In that surviving case, a district court in 1998, and the Court of Appeal in 2000, both reaffirmed that the crash had been an accident, the latter in an 800-page judgment. A 2001 bid to reopen the matter on the strength of new evidence was again ruled time-barred, and Portugal's Supreme Court dismissed further legal challenges in 2006. Relatives of the victims then appealed to the European Court of Human Rights in 2007, arguing that delays by Portuguese authorities had unfairly denied them access to a court; the court ruled against them in 2011, finding no negligence or failure to act.
Even as the courts closed the door on prosecution, a parliamentary inquiry reached a different conclusion: its eighth investigation into the crash, reporting in 2004, found unanimously that the aircraft had been brought down by an explosive device. After the case's 15-year statute of limitations lapsed, individuals came forward publicly describing an alleged role in planning an attack on the aircraft, including a claim that a device had been built to start a pre-flight fire rather than cause a fatal crash. None of these claims has led to criminal charges or been independently verified. No one has ever been charged in connection with the crash, and investigators remain divided on whether it was an accident or an act of sabotage.
