Quick Launch

NTSB Identification: CEN14FA506
14 CFR Part 91: General Aviation
Accident occurred Friday, September 19, 2014 in Okmulgee, OK
Probable Cause Approval Date: 06/22/2016
Aircraft: CESSNA 172R, registration: N2435R
Injuries: 1 Fatal.

NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The instrument-rated pilot obtained weather information about 1 hour 45 minutes before takeoff. The weather information included an AIRMET that indicated that instrument flight rules (IFR) conditions existed at the takeoff and destination locations and along the intended route of flight due to precipitation and mist. No evidence was found indicating that the pilot obtained additional weather information.
Radar data showed the airplane proceeding toward the destination airport until about 22 miles from the destination, at which point the airplane began a series of turns for undetermined reasons before attempting an approach to a different airport. Radar data then showed the airplane enter a climbing turn away from the airport that did not follow any published missed approach procedure. Shortly after performing the turn, the airplane collided with trees and terrain. There is no evidence that the pilot attempted to obtain an IFR clearance or made any distress calls. Examination of the airframe and engine did not reveal any anomalies that would have precluded normal operation. The pilot had several medical conditions; however, there is no evidence that a medical condition contributed to the accident.


The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • The pilot's continued visual flight into instrument meteorological conditions, which resulted in his failure to maintain clearance with trees and terrain.
