NTSB summary
HISTORY OF FLIGHT On September 5, 2014, about 1410 eastern daylight time (EDT), a Daher-Socata TBM700 (marketed as a TBM900 model), N900KN, was destroyed when it impacted open water in the Caribbean Sea near the northeast coast of Jamaica. The commercial pilot and the passenger were fatally injured. An instrument flight rules flight plan was filed for the cross-county flight that originated from Greater Rochester International Airport (ROC), Rochester, New York, at 0826 and was destined for Naples Municipal Airport (APF), Naples, Florida. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations (CFR) Part 91.

Once his wife arrived, they loaded their bags and then boarded the airplane. An FBO employee pulled the chocks and marshalled the airplane off the FBO ramp. Surveillance video retrieved from the ROC airport showed that the airplane departed at 0826.

Several minutes later, the controller instructed the pilot to climb to Flight Level (FL) 280, and th
Probable cause
The design of the cabin pressurization system, which made it prone to unnecessary shutdown, combined with a checklist design that prioritized troubleshooting over ensuring that the pilot was sufficiently protected from hypoxia. This resulted in a loss of cabin pressure that rendered the pilot and passenger unconscious during cruise flight and eventually led to an in-flight loss of power due to fue
