This aircraft is known as a AIR BEETLE TRIANING AIRCRAFT. It has been out of use for a decade by the NIGERIA AIRFORCE.
It was made in Nigeria in the year 1989(was flown and serviceable in that year) by the Nigeria Airforce. The Air Beetle is a Van RV-6A; the only kit built aircraft that is used as a military training aircraft.
The air training school is located in Kaduna state, Nigeria. The Beetle Aircraft was assembled and maintained by Dornier Aviation Nigeria (DANA).
I found these old aircrafts in one of the Nigeria Airforce hanger in kaduna, Nigeria at the flying training school where I am working as an Industrial Training Student.
