What happened
On the evening of July 19, 1962, a commercial pilot who was not instrument-rated embarked on a night cross-country flight over high mountainous terrain with three passengers. During the flight, the aircraft collided with rising terrain at an altitude of approximately 9,200 feet mean sea level. The impact resulted in extensive damage to the airplane, which came to rest on a steep slope angled at 30 degrees.
Following the collision, the aircraft was reported missing. Despite search efforts, the wreckage remained undiscovered for more than three decades. It was not until August 8, 1994, that trail repair personnel located the remains in a remote area of Yosemite National Park. Alongside the wreckage, human remains were recovered from the site.
The investigation
Because the accident occurred prior to the establishment of modern record-keeping protocols for this specific incident, neither the Federal Aviation Administration (FAA) nor the National Transportation Safety Board possessed any official records or documentation regarding the flight at the time of discovery.
The registration number associated with the aircraft had been reassigned to a different aircraft in 1972, complicating identification efforts. Consequently, U.S. Park and County Sheriff's Department personnel conducted a coroner's investigation to manage the aftermath and identify the victims.
Findings
The primary finding was the confirmation that the aircraft had crashed in rugged terrain during night conditions. The lack of available records meant that the specific cause of the collision could not be determined through standard investigative channels at the time of discovery. The case remained open due to the absence of data until the physical evidence was recovered.
Safety message
This incident highlights the critical importance of maintaining accurate and accessible aviation records, particularly for flights operating in remote or hazardous environments. It also underscores the risks associated with night cross-country flights over mountainous terrain by pilots who are not instrument-rated.
