The accident is especially notable because 9S-AJO was among the last DC-8s still flying commercially. The approximately 56-year-old aircraft was Trans Air Cargo Service’s only active aircraft, according to fleet databases.

The jet was originally built as a DC-8-63, part of the stretched “Super 60” series. It was later converted to the DC-8-73 standard with quieter and more fuel-efficient CFM56 turbofan engines.

Only a small number of DC-8s remained operational worldwide before the Kinshasa accident. Another DC-8-73 freighter, registered OB-2231P, has been operated by Peru-based Skybus Jet Cargo. //

Douglas and McDonnell Douglas built 556 DC-8s before production ended in 1972. Although the type disappeared from scheduled passenger service decades ago, several re-engined examples continued flying as freighters, research aircraft and humanitarian transports.

NASA retired its DC-8 flying laboratory in 2024, while Samaritan’s Purse retired the last US-registered operational DC-8 in 2025.
