On April 26, 2001 at about 11:29 am local time, a Mcdonnell Douglas DC-8-71F, registered N8076U, suffered minor damage in an incident near Nashville, Tennessee (Nashville International airport). It was flown under scheduled airline rules (Part 121). No one was hurt; 3 people were on board or involved. The weather was visual conditions (good weather).
The NTSB's probable cause their words, unchanged
The failure of company maintenance personnel to install the correct hydraulic landing gear extension component, and the failure of company maintenance inspection personnel to comply with proper post maintenance test procedures, resulting in the impossibility of the LMLG to extend, and the subsequent LMLG up landing. A factor in the accident was the improper identification tag marking on the replacement component, and no marking on the component, itself.

The NTSB's narrative final · quoted from the NTSB record
According to the pilot, the freighter flight was normal in all aspects until the landing gear were extended for landing at destination. The left main landing gear, (LMLG) indicated "unsafe", and all attempts, using the emergency/abnormal checklists and telephone/radio-relayed communications with company maintenance, failed to extend it. An emergency, LMLG retracted landing was performed with minimal damage to the aircraft. Postcrash investigation revealed that company maintenance installed a one-way check valve in the LMLG extend hydraulic lines instead of a restricted flow valve. The wrongly installed valve had no factory specification or part number attached, and the tag reportedly removed from it at installation possessed the wrong factory specification number, and the correct vendor' s part number. The company maintenance manual states that upon completion of the valve installation, a leak and operational test of the MLG retract/extension system be performed. The valve installation mechanic and the company inspector both stated that the finished job was leak and "ops" tested.
