The plane crashed Friday night just short of the Terravista Airport, a gateway for well-heeled guests arriving at the exclusive Terravista golf and condominium resort in the town of Trancoso, according to the state-run Agencia Brasil news agency.
Medical examiner Antonio Carlos Batista Brito said authorities determined the crash killed 14 people, all on the plane, raising the initial death toll by three.
Their "completely charred bodies" were sent to the Bahia state capital of Salvador where coroners will try to identify the remains through DNA tests or dental records.
The King Air B350 model plane, which Wright owned, left Sao Paulo at 6:31 p.m. and crashed at 9:13 p.m., said an air force spokesman who spoke on condition of anonymity in keeping with air force rules.
Moments before hitting the ground, the pilot reported that "visual and landing conditions were normal," according to a statement issued by the airport.
The cause of the crash was not known.
Trancoso and its resorts are among Brazil's most famous because of the area's pristine beaches, year-round balmy climate and luxury accommodations. The destination is a getaway for rich Brazilians and foreigners.
The Terravista complex and its golf course lie next to a Club Med resort, and the airport boasts a 1,500-meter (4,921-foot) runway that is illuminated for night landings and takeoffs, according to Terravista's Web site.
