ADC Airlines Flight 086 was a scheduled domestic flight from Abuja to Lagos, Nigeria. The aircraft was a Boeing 727-200, an airliner widely used during the 20th century for both domestic and international flights. On this flight, as the plane approached Lagos at around 6:45 PM local time, it began experiencing difficulties due to adverse weather conditions. Witnesses reported that the aircraft was struggling to maintain altitude and orientation as it neared its destination.

As Flight 086 attempted to land, it veered off course and ultimately crashed into the Lagos Lagoon in Epe, a coastal city within the Lagos State region. The local population witnessed the dramatic descent and crash, which resulted in a significant explosion on impact. Rescue operations commenced immediately, but unfortunately, none of the 144 passengers and crew members survived. Wetter conditions included overcast skies and rain, contributing to the aircraft's difficulties.

Investigations into the crash were conducted by Nigerian authorities, supported by various international bodies.
