Investigation Summary
Flight 808 was a Department of Defense charter carrying mail and perishable goods. The crew was originally scheduled to end their shift in Atlanta but was reassigned to the Guantánamo mission after another aircraft suffered mechanical issues. To align with Runway 10 at Leeward Point Field, pilots must perform a sharp turn to remain within U.S. controlled airspace and avoid Cuban territory, traditionally marked by a strobe light on the border fence. On the day of the accident, the strobe light was inoperative. The Captain, severely fatigued, became fixated on locating the light and overshot the turn. In an attempt to salvage the approach, he increased the bank angle to over 60 degrees while allowing the airspeed to decay. The aircraft stalled at approximately 200 to 300 feet above the ground, rolled to 90 degrees, and struck the terrain. The cockpit section sheared off and tumbled, which likely contributed to the crew's survival as the rest of the airframe was consumed by fire.
Final Conclusions
The NTSB determined the probable cause was the impaired judgment and flying abilities of the captain and crew due to the effects of fatigue. Contributing factors included the captain's failure to maintain situational awareness, the failure to prevent a loss of airspeed during a steep bank, and the lack of immediate stall recovery actions. The board also cited inadequate crew resource management (CRM) training, inadequate training for special airports, the role of the inoperative strobe light, and the regulatory environment that allowed the crew to remain on duty for excessive periods.

Airframe & Maintenance
Crew Experience
Captain
Awake for 23.5 hours at time of accident. Former Eastern Air Lines pilot.
First Officer
Awake for 19 hours at time of accident. Former U.S. Navy and Eastern Air Lines pilot. Later became an NTSB investigator.
Flight Engineer
Awake for 21 hours at time of accident. Former Trans Continental Airlines pilot.
Systems & Failure Modes
Stall Warning System
The aircraft's stick shaker activated during the steep turn, but the fatigued crew failed to take immediate corrective action to reduce the bank angle or increase thrust.
Visual Landing Aids
A strobe light on the Cuban border fence was a critical reference for the Runway 10 approach; its failure contributed to the Captain's spatial disorientation and fixation.
Interesting Facts
- 01The Captain had been awake for 23.5 hours at the time of the crash.
- 02The strobe light used to identify the 'dead line' (Cuban border) was inoperative, unknown to the crew or the controller.
- 03The cockpit separated from the fuselage upon impact, coming to rest inverted.
- 04This was the first NTSB report to cite pilot fatigue as a primary cause of an accident.
- 05The First Officer's right leg was amputated due to his injuries, but he later returned to flying and eventually became an NTSB investigator.
Safety Actions & Advisories
Fatigue Research and Regulation
The NTSB issued recommendations to the FAA to update crew scheduling and duty time limits based on modern sleep and circadian rhythm research.
Guantánamo Approach Modification
The approach path to Runway 10 was later modified in cooperation with the Cuban government to provide pilots more room to align with the runway.
Special Airport Qualification Loophole
The NTSB recommended the FAA eliminate the exemption in 14 CFR 121.445(c) that allowed pilots to operate into 'special' airports without specific qualification if the weather was above certain VFR minimums.
