Preliminary Report on Associated Airline Crash Points To IT Failure
![Stella Oduah, minister of Aviations](https://www.nigeriacommunicationsweek.com.ng/wp-content/uploads/2014/03/odua_18.jpg)
The Accident Investigation, Prevention Bureau (AIPB) has released a preliminary associated airline crash involving embraer 120 aircraft registered 5n-BJY which occurred at MMA on Thursday 3rd October, 2013while conveying home the remains of Olusegun Agagu, former Governor Ondo State for burial.
A statement endorsed by Capt. Muktar Usman, commissioner, Accident Investigation, Prevention Bureau (AIPB), reads as follows: “The following information has been determined from preliminary readout and analysis of flight 361’s flight recorders. Flight 361 was equipped with both a COCKPIT VOICE RECORDER and a FLIGHT DATA RECORDER. Both recorders were replayed at the Accident Investigation Bureau’s recently acquired flight recorder laboratory located in Abuja. International flight recorder experts from Canada who designed the laboratory assisted the investigation team with the readout and analysis process along with representatives from the aircraft manufacturer and aircraft operator, Associated Airlines. We are conducting the investigation in accordance with the provisions of International Civil Aviation Organization (ICAO) Annex 13, of which Nigeria is a member State.
“The flight data recorder or FDR contained approximately 47 hours of data in solid state memory. The recorder downloaded without issue. There were approximately 50 parameters recorded. A few parameters were not working properly however we do not think, in this particular case, that it will hamper the overall investigation.
“The cockpit voice recorder or CVR was an older generation magnetic tape based device. The CVR’s magnetic tape recording was removed from the unit and replayed on an open reel 4 track tape deck specially adapted for replaying CVR’s of this type. The CVR contained 32 and one half minutes of audio which included the internal conversation of the two pilots, radio calls and the overall aural environment in the cockpit on the cockpit area microphone. The CVR was of good quality and the team is in the process of generating a complete transcript of all relevant information. The AIB plans to release the transcript as part of its final report of the accident however the actual recording is, under international protocol, sensitive and therefore privileged information and will not be released at any time.
The following represents information that has been determined from our preliminary assessment of both flight recorders:
“The crew discussed some concerns about the aircraft prior to departure but at this time we are not prepared to elaborate on those concerns as there remains a lot of work to complete on the CVR analysis in order to determine the specific nature of the crew’s concerns.
Associated 361 was cleared for take-off on runway one eight left at Lagos international airport. The wind was calm and weather is not considered a factor in this accident. Approximately 4 seconds after engine power was advanced to commence the take-off roll, the crew received an automated warning from the onboard computer voice which consisted of three chimes followed by “Take-off Flaps…Take-off Flaps”. This is a configuration warning that suggests that the flaps were not in the correct position for take-off and there is some evidence that the crew may have chosen not to use flaps for the take-off. The warning did not appear to come as any surprise to the crew and they continued normally with the take-off. This warning continues throughout the take-off roll. As we are in the process of verifying the accuracy of the flight data, we have not yet been able to confirm the actual flap setting however we expect to determine this in the fullness of time.
“It was determined from the CVR that the pilot flying was the Captain and the pilot monitoring and assisting was the First Officer.
“The ‘set power‘call was made by the Captain and the ‘power is set’ call was confirmed by the First Officer as expected in normal operations. Approximately 3 seconds after the ‘power is set’ call, the First Officer noted that the aircraft was moving slowly. Approximately 7 seconds after the ‘power is set’ call, the internal Aircraft Voice warning system could be heard stating ‘Take off Flaps, Auto Feather’. Auto feather refers to the pitch of the propeller blades. In the feather position, the propeller does not produce any thrust. The FDR contains several engine related parameters which the AIB is studying. At this time, we can state that the Right engine appears to be producing considerably less thrust than the Left engine. The left engine appeared to be working normally. The aircraft automated voice continued to repeat ‘Take-off Flaps, Auto Feather’.
The physical examination of the wreckage revealed that the right engine propeller was in the feather position and the engine fire handle was pulled/activated.
“The standard ‘eighty knots’ call was made by the First Officer. The first evidence that the crew indicated that there was a problem with the take-off roll was immediately following the ‘eighty knots’ call. The First Officer asked if the take-off should be aborted approximately 12 seconds after the ‘eighty knots’ callout. Our investigation team estimates the airspeed to be approximately 95 knots. Airspeed was one of the parameters that, while working in the cockpit, appeared not to be working on the Flight Data Recorder. We were able to estimate the speed based on the radar data that we synchronized to the FDR and CVR but it is very approximate because of this. In response to the First Officer’s question to abort, the Captain indicated that they should continue and they continued the take-off roll.
“The crew did not make a ‘V1’ call or a Vr’ call. V1 is the speed at which a decision to abort or continue a take-off is made. Vr is the speed at which it is planned to rotate the aircraft. Normally the non-flying pilot calls both the V1 and the Vr speeds. When Vr is called the flying pilot pulls back on the control column and the aircraft is rotated (pitched up) to climb away from the runway. During the rotation, the First Officer stated ‘gently’, which we believe reflects concern that the aircraft is not performing normally and therefore needs to be rotated very gently so as not to aerodynamically stall the aircraft.
“The First Officer indicated that the aircraft was not climbing and advised the Captain who was flying not to stall the aircraft. Higher climb angles can cause an aerodynamic stall. If the aircraft is not producing enough overall thrust, it is difficult or impossible to climb without the risk of an aerodynamic stall.
“Immediately after lift-off, the aircraft slowly veered off the runway heading to the right and was not climbing properly. This aircraft behavior appears to have resulted in the Air Traffic Controller asking Flight 361 if operation was normal. Flight 361 never responded.
“Less than 10 seconds after rotation of the aircraft to climb away from the runway, the stall warning sounded in the cockpit and continued to the end of the recording. The flight data shows characteristics consistent with an aerodynamic stall.
“31 seconds after the stall warning was heard, the aircraft impacted the ground in a nose down near 90 degree right bank.
The investigation is focussing on the following:
1) Mechanical and electronic engine control issues related to the Right engine and Right engine propeller systems.
2) Aural warnings related to auto-feather and the flap settings required for takeoff.
3) Take-off configuration issues with respect to flap settings.
4) Crew decision making and training with respect to proceeding with the flight despite concerns regarding the aircraft’s suitability for flight.
5) When and how the number 2 engine fire handle was pulled.
6) Standard operating procedures with respect to continuing the take-off roll despite continuous automated voice warnings of both ‘take-off flaps’ and ‘auto feather’ when there was ample time to abort the take-off.
7) The airline management’s safety culture fostered throughout the airline.
“We are in the process of developing a comprehensive computer reconstruction of the flight which will help our team understand the sequence of events and will ultimately help us communicate our findings to the aviation community and the general public.
“At this time we have no urgent safety recommendations. We will not wait for the final report to issue safety recommendations should any issue arise that we feel needs immediate attention.

FG Drops Merger of NCAA, NAMA
![](https://www.nigeriacommunicationsweek.com.ng/wp-content/uploads/2025/02/Festus-Kayamo-Aviation-minister.jpeg)
The Minister of Aviation and Aerospace Development, Festus Keyamo has disclosed that President Bola Tinubu has stepped down the merger of the Nigeria Civil Aviation Authority (NCAA) and the Nigerian Airspace Management Agency (NAMA) as recommended by the Steve Oronsaye report.
He also revealed that the aviation industry was exempted from the foreign travel ban placed on federal government officials last year. The President announced the ban which took effect from April last year.
Keyamo disclosed that the aviation sector was exempted from the ban because President Tinubu is desirous of change and growth in the sector.
The ban was placed following the rising cost of travel expenses by Ministries, Department and Agencies of Government.
The memo released last year stated: “Considering the current economic challenges and the need for responsible fiscal management, I am writing to communicate Mr Presideni’s directive to place a temporary ban on all publicly funded international trips for all federal government officials at all levels, for an initial period of three months from 1st April 2024.
“All government officials who intend to go on any publicly funded international trips must seek and obtain Presidential approval at least two weeks before embarking on any such trip, which must be deemed necessary”.
The Minister disclosed the reasons for the exemption in Abuja at the 25th anniversary celebration of the Nigeria Civil Aviation Authority (NCAA).
On the merger of NCAA and NAMA, he said: “From modest beginnings, we have witnessed remarkable transformations in our sector, ranging from enhanced supervisory measures and policies formulation, safety and security oversight, robust legislative and regulatory frameworks, advancements in air traffic management, development, expansion and certification of airports, accurate meteorological services, timely accident investigations, manpower development, and indeed, the growth of indigenous airlines.
“These achievements have not come without challenges. However, with the efforts of past administrations and the total support of the present administration under the dynamic leadership of His Excellency President Bola Tinubu through the Renewed Hope Agenda and the five focus areas of the ministry, we have overcome challenges and reached new heights.
“NCAA is a child of God, and despite turbulent waters and attempts sometimes to kill the NCAA, the NCA has survived 25 years. And I’m sure you know that any child that is born at the age of 25, of course, is undoubtedly an age of maturity.
“The Oronsanye reports also recommended the merger of NCAA and NAMA. And so that was also another attempt to kill the NCAA. That report was passed from Jonathan’s government to Buhari’s government, and then to the present government.
“It was one of the first items we considered in this government. So the Oronsanye reports came up that day, and the president went on and on, considered every item in the Oronsanye report, and asked the council to vote. And for each item, they would listen to the ministers and so the president came to the merger of NCAA and NAMA as one body.
“I raised my hand, I spoke for about five minutes and because we have a wonderful president who listens to good counsel and good arguments, after I finished speaking, he said, an item dropped, the merger of NCAA and NAMA would not remain”.
On the reasons for the exemption, he said: “It is a fact that the aviation sector remains a pillar of national development, facilitating trade, tourism, investment, and cultural exchange. Whilst it is yet to realize its true potential in terms of contribution to our nation’s Gross Domestic Product (GDP), we must renew our commitment to ensuring a more progressive, sustainable, inclusive, innovative, and prosperous aviation industry.
“This necessitates the continuous adoption and integration of emerging technologies, enhancing infrastructure, and investing in human capital development to keep our skies safer and secure and attain cohesive and efficient air transportation services.
“The President directed that foreign travels should stop, except in exceptional circumstances. Last year, there was a memo around March that said it was for three months, and the President, because of his desire to ensure that we are frugal in our spending; there was another memo again in December reiterating that memo last year we should cut down on foreign travels, except by direct presidential approval.
“But let us also give particular thanks to Mr. President, because despite that memo, since last year, he has made an exception for the aviation industry. I wrote a memo to him after that directive on behalf of the entire agency that says; Sir, we respect your directive; yes, we need to be frugal because the Nigerian people have also tightened their belts in the face of the economic reforms that are taking place.
“However, because of the safety of this sector, Sir, we need to make some exceptions for this sector. And the President graciously granted this for the aviation sector”.

Researchers Develop Innovative Treatment for Malaria
![](https://www.nigeriacommunicationsweek.com.ng/wp-content/uploads/2022/05/malaria-vaccine.jpg)
An international team of researchers have introduced a groundbreaking drug, known as the covalent kinase inhibitor, which shows promise in combating treatment-resistant malaria.
Developed by chemists and bioscientists from the University of Glasgow, this innovative drug could surpass current medications by effectively targeting and disabling the proteins used by the Plasmodium falciparum parasite to replicate within the human body.
This is according to a report titled “Targeting Pf CLK3 with Covalent Inhibitors: A Novel Strategy for Malaria Treatment.”
The development, led by chemists and bioscientists from the University of Glasgow, was outlined in a November publication in the “Journal of Medicinal Chemistry.”
According to the researchers, covalent inhibitors form bonds with proteins, usually irreversibly modifying them, and this new drug could be more effective than current medications at all stages of malaria infection.
The new drug works by permanently disabling a protein that Plasmodium falciparum, one of the mosquito-borne parasites that spread malaria, uses to replicate itself inside the human body.
The drug also has the potential to work as a single-dose treatment, a significant improvement over existing therapies.
This breakthrough marks the first adaptation of an approach from cancer treatments to tackle malaria.
The team expressed optimism that the parasite is unlikely to develop resistance to the new drug, which targets the protein Pf CLK3 and disrupts the parasite’s ability to splice RNA.
The researchers, including Prof. Martins Emeje from the Nigerian Natural Medicines Development Agency and Prof. Oyewale Tomori from the West African Academy of Sciences, emphasise the importance of regular calibration and accreditation for medical laboratories to ensure accurate results and reliable treatment.
