Sam Mbakwe International Cargo Airport (IATA: QOW, ICAO: DNIM), also known as Imo State Airport, serves Owerri, the capital city of Imo State in southeastern Nigeria. The airport is named in honor of a former governor and politician-philanthropist, the late Chief Sam Mbakwe of Imo State. It is the first state government-built airport. It was first conceived by the late former governor, Chief Sam Mbakwe in 1982. Construction started in 1984 by the former military governor of Imo state Brig. General Ike Nwachuwu and was completed in 1996. It was later taken over by the federal government. The airport recently underwent upgrading (2013-14) which covered the physical infrastructure as well communication equipment covering its air space as far Port Harcourt Airport and beyond as part of the Total Radar Coverage of Nigeria (TRACON).
The airport has night landing capabilities but, like most flights in non-international designated airports, the Federal Airports Authority of Nigeria restricts night operations except for airlifting passengers during pilgrimage (Hajj) operations.
Currently the cargo section is undergoing expansion works and should be completed by 2016.
