The L-39ZA is an armed version reconfigured locally to carry rocket pods and a pair of 250 kg bombs, and equipped with Western avionics. The aircraft arrived in Nigeria in two batches in 1986 and 1987. They’re based in Kano at the 303rd Aviation School, 403 Flying Training School, and their main task is to train pilots and ground attacks.
Nigeria directly performs L-39 life extensions programs at the base in Kano by a team of specialists from Aero supported by local engineers and technicians.
State-owned Czech company LOM Praha began training the Nigerian pilots in the first half of 2018 at the CLV Pardubice air training center in the Czech Republic to improve their air-to-air and air-to-ground combat skills.
The NAF pilots completed 150 hours of training on the L-39C at LOM Praha flight training centre (CLV) Pardubice in Czech Republic.
