IAC Ilorin Incident: Inappropriate Execution Of Landing Checklist Contributed, Says AIB Report

The inappropriate execution of approach and landing check list constitute part of the three contributory factors responsible for the serious incident involving a Diamond DA-42 aircraft with Nationality and Registration Marks, 5N-BNH owned and operated by the International Aviation College which occurred on Runway 23 Ilorin International Airport on 1st of May, 2019.
This is according to the occurrence report released today by the Accident Investigation Bureau (AIB). Other contributory factors were inadequate crew coordination during the approach to landing phase of flight and lack of situational awareness on the position of the landing gears by the flight crew during approach to land.
The flight was a Commercial Pilot Licence (CPL) mock test with two persons onboard, a Flight Instructor (FI) and a Student Pilot (SP) with the flight instructor flying while the student pilot was monitoring.
At about 09:13 h, 5N-BNH took off from runway 23, Ilorin International Airport to Sector One Charlie (1C) and reported established at 09:28 h.
Several manoeuvres were carried out including steep turn, stall in all configurations, emergency descent, one engine inoperative procedure etc.
After two hours of flying at the training area, 5N-BNH was cleared back to the field for RNAV, VOR hold and ILS Approach and missed approach exercises.
At 11:12 h, the aircraft 5N-BNH reported right downwind Runway 23, requesting full stop landing and was granted. The flight instructor did his pre-landing checks.
At 11:15 h, the aircraft touched down with gears up on the runway centreline at a distance of 1,387 m from the threshold, veered right of the runway centerline and stopped 205m from the touchdown point, 9m to the right of the runway centreline. The incident occurred in daylight.
Presenting the report today at a press conference, the AIB Commissioner, Engr. Akin Olateru said three safety recommendations were made. They are that “NCAA should intensify its oversight on International Aviation College (IAC) and ensure that it adheres strictly to the use of Checklists and appropriate procedures during all training sessions and phases of flight.
International Aviation College (IAC) should improve on its Crew Resource Management training vis-à-vis the need for trainees to be assertive when necessary and NAMA should devise means to ensure duty air traffic controllers, DATCOs, maintain continuous watch on all aircraft movements within the vicinity of the aerodrome.”
Olateru declared that “since the inception of this administration at AIB, we have been able to keep to our promise of ensuring timely release of accident and serious incident reports. We have before now released 27 final accident reports to the public and today, we will be releasing an additional four reports, which will bring the total final report released by this administration from 2017 till date to 31.
