he became spatially disoriented and accidentally caused the plane to enter an unrecoverable bank and attitude. The NTSB also focused on the aircraft's attitude indicators (ADI), human factors, the power changes by using the Flight Data Recorder (FDR), and the manner of first officer Hupp's approach. Because of the aircraft's previous cargo door incident, the NTSB considered the possibility that the aircraft had once again experienced a cargo door opening mid-flight. Seven door latches were found; one of which had lost its latch pins on impact. If the cargo door had opened in mid-flight the CVR would suddenly record a loud sound of rushing air. Flight 805's CVR did not record this, nor the flight crew did bring up any abnormal sounds. The crew also didn't bring up the door warning light. Thus, the NTSB concluded that the cargo door had been functioning normally, did not open in mid-flight, and was not a factor in the accident. The ADI malfunction was the most likely scenario, as the NTSB was unable to determine its readings at impact. However, only one ADI was recovered and had been severely damaged from the crash. The NTSB alluded to previous accidents which involved ADI malfunctions. The NTSB did believe that the first officer's ADI was functioning normally at the time of the accident because of his immediate response to captain Baker transferring control of the aircraft back to him, and properly executing the recovery attempt. The report stated: In addition, the flight crew's interactions were not representing proper crew resource management (CRM). The NTSB was also unable to determine why the first officer caused the aircraft to destabilize on approach. The NTSB released the final report on November 19, 1992, with the "probable cause" stating: The NTSB was unable to determine with absolute certainty if any of these aforementioned factors (except for the cargo door incident which had been ruled out) had caused or contributed to the accident. The NTSB could not determine the time that control of the aircraft was lost. Aftermath The NTSB did not issue any recommendations following the accident.
