Incident Overview
Description
The Twin Otter crashed after striking trees with the right wingtip and horizontal stabilizer. The trees were located on a 2700 feet hill; the MDA at that point is 3700 feet. A runway 22 instrument approach had to be flown due to bad weather (heavy rain, low clouds, severe turbulence), but the ILS glide path was out of calibration. The pilot is believed to have been flying an ILS localizer approach and using the AU VOR/DME. The pilot possibly thought the AU VOR was located at the runway threshold, while it was actually located 1,3nm short of it, causing a premature descent. CAUSE: Navigation error by the Commander of the aircraft in tracking, the V.O.R signal on the final approach phase of the flight into Abuja Airport. The turbulent weather was also considered to have contributed to the accident.
