Texas International Airlines Flight 655, registration N94230, was a Convair 600 en route from Memphis, Tennessee, to Dallas, Texas via Pine Bluff, Arkansas; El Dorado, and Texarkana that crashed into Black Fork Mountain, Arkansas on the night of September 27, 1973. The 8 passengers and 3 crewmembers were killed.

Events

While the plane was on the ground in El Dorado the crew consulted with Flight Service Station staff and another set of pilots about a line of thunderstorms 35 nm to the west. After confirming there was a 15 nm wide break in the storm the crew departed at night under visual flight rules (VFR). After departing El Dorado no contact was made with any controllers en route. When the plane was overdue at Texarkana search and rescue was notified. Despite an extensive search along the proposed route of flight no wreckage was found. A controller at the Fort Worth air traffic control center advised the searchers that he had observed an unidentified VFR target departing El Dorado to the northwest before the plane went missing. With this information the wreckage was found after 3 days of searching. There were no survivors.

The cockpit voice recorder later revealed the First Officer was flying the plane while the Captain advised him of headings and altitudes to take to navigate around the storm. The Captain deviated the plane 100 nm to the north in an attempt to go around it. The First Officer expressed concern that he did not know their position and what the terrain clearance was for the area. After the Captain ordered him to descend to 2,000 feet he consulted an en route instrument chart. He alerted the captain they were too low saying, "Minimum en route altitude here is forty-four hun . . ." At that point the recorder cut off as the plane impacted Black Fork Mountain.

The NTSB investigation concluded that the crew did not discuss the details of their intended route with Flight Service or activate the instrument flight rules (IFR) flight plan forwarded from the airline dispatch to Flight Service. If they had been operating under instrument flight rules they would have been radar tracked or required to make position reports to air traffic control en route. Under visual flight rules they would only need to maintain contact with a controller while in controlled airspace. In this area of rural Arkansas there was no controlled airspace below 18,000 feet. Further according to Federal Aviation Regulations the airline dispatcher should have been notified the flight was proceeding VFR. The Captain also could have contacted controllers in Fort Worth to open their flight plan or receive radar vectoring in the area. From the conversation of the crew on the recorder the board concluded the flight encountered instrument weather conditions during the flight and was likely in instrument weather conditions when it crashed. The board concluded that the cause of the accident was the Captain's decision to continue flying into instrument weather at night. Also not taking advantage of the nearby navigational aids to get a fix on their position. Lastly his decision to descend despite the First Officer's concerns about position and terrain.
