NTSB narrative

AT APPROXIMATELY 0400 HOURS E.D.T. PAN AMERICAN FLIGHT #201 FROM NEW YORK TO RIO DE JANEIRO ENCOUNTERED TURBULENCE AT FLIGHT LEVEL 370 IN THE VICINITY OF GEORGETOWN, GUYANA. SEVERAL PASSENGERS AT ROW 50 RECEIVED INJURIES. THE FASTEN SEAT BELT SIGN WAS ON AT THE TIME AND THE CAPTAIN HAD ANNOUNCED THE ILLUMINATION OF THE SIGN OVER THE PA SYSTEM.

Probable cause

INCIDENT THAT LED TO THE DEATH OF THE PASSENGER IN ROW #6 WAS APPARENTLY NOT RELATED TO TURBULENCE, BECAUSE THE PASSENGER DIED OF CHOKING TWO HOURS AFTER THE TURBULENCE ENCOUNTER.

Source notes (5)
  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status, damage. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
  • API snapshot SHA-256: 9aacf2ec980d69a26032f0f048b2e51bb3f5630a57ca3b21251d74f7c5fec770; retrieved 2026-09-18T19:18:35.431Z.
  • Corrected after a review of the NTSB narrative, which states these values explicitly: operator. The NTSB narrative names the operator: "PAN AMERICAN FLIGHT #201 FROM NEW YORK TO RIO DE JANEIRO ENCOUNTERED TURBULENCE AT FLIGHT LEVEL 370"
