UTA Flight 141

UTA Flight 141 was a scheduled international passenger flight operated by Guinean regional airline Union des Transports Africains de Guinée (UTA), flying from Conakry to Dubai with stopovers in Benin, Libya and Lebanon. On Christmas Day 2003, the Boeing 727–223 operating the flight struck a building and crashed into the Bight of Benin while rolling for take off from Cotonou, killing 141 people. The crash of Flight 141 is the deadliest crash in Benin's aviation history.

The investigation concluded that the crash was primarily caused by overloading. However, it also subsequently revealed massive incompetence within the airline, particularly on its dangerous safety culture. The issue had gone unnoticed following lapses between authorities and further incompetence in management oversight led to the aircraft's overloaded state. Multiple factors, including the short runway at Cotonou and the high demand of passengers for the route, had also contributed to the crash.

In regards to the result of the investigation, the Guinean government was urged to create reforms and regulations on the civil aviation authorities in the country. The BEA, the commission responsible for the investigation, had also urged ICAO to examine provisions related to safety oversight and the FAA and the European EASA were asked to support the creation of an autonomous weight and balance calculation system on board every airliner.

Background

In the 20th century, most countries in West Africa did not have the capability to create and maintain a national airline. For decades, flight routes in West Africa were mainly served by Air Afrique, a transnational airline for Francophone West and Central Africa. It was once considered one of the largest airlines in Africa and one of the most reputable. However, after reports of mismanagement, corruption and the fallout of the aviation industry following the September 11 attacks, Air Afrique declared bankruptcy in 2002.

In the aftermath of Air Afrique's demise, there were no more routes connecting major cities in West Africa and to other regions. The bankruptcy of Air Afrique caused isolation between the countries, despite their close geographical location. While Air Afrique's routes were immediately taken over by Air France, most of the flights were perceived as inconvenient. Such an example was a flight from Conakry to Cotonou, in which passengers had to fly to Paris first before they could continue to Cotonou. Immediately, there was high demand for new airlines to open more direct routes.

In an attempt to fill the void left by Air Afrique, multiple existing small airlines began to offer services to these major routes. Among them was Union des Transports Africains de Guinée, or UTA, a regional airline that was operated by Lebanese people in Guinea. Although it shared an abbreviation, this UTA had no relation to the more well-known French airline Union de Transports Aériens, which operated from 1963 to 1992 and served many African destinations.

For years, the Lebanese diaspora was part of the backbone of the economic activity in multiple West African countries. Many Lebanese businessmen had forged robust relationships with government officials to sign contracts within West Africa's public infrastructure sectors, and many Lebanese owned large businesses in West Africa. An example was cited on a CIA document from 1988, with the following quote explaining the economic situation in one of the West African countries:

However, the lack of direct flights to Lebanon caused dozens of Lebanese to board transit flights between multiple cities in West Africa. Lebanon's flag carrier, Middle East Airlines, previously had operated flight routes in West Africa and later decided to terminate the service.

On 23 July 2003, the government of Benin granted temporary authorization for UTA to operate charter flights for Conakry – Cotonou – Beirut – Cotonou – Conakry route. The airline later requested clearance to operate another extension flight to Dubai, known for its duty-free shopping, possibly to amplify profitability. The request was granted in November 2003.

Flight

Flight 141 was a chartered passenger flight from the Guinean capital of Conakry, Benin's largest city of Cotonou and the Lebanese capital of Beirut with the final destination in Dubai. A stopover was included in the flight plan with the Libyan town of Kufra as a refueling stop. It was a weekly scheduled flight with one round trip flight per week.

The aircraft had been chartered by 2 Lebanese men. Many of those on board were Lebanese diaspora who had been living in multiple West African countries for years. As it was Christmas Day, many of those on board were travelling home to spend the holidays with families. Dozens of passengers could be seen carrying hand baggage filled with Christmas gifts. The situation was chaotic as the check-in staff at the airport had not allocated seats for the passengers. A boarding pass was also not needed at the airport. Passengers could sell their respective seats at last-minute to someone else who were not booked on the flight as their names were not written on the boarding pass.

The aircraft was full with passengers. A total of 86 people had boarded the aircraft in Conakry and 9 people had disembarked in Cotonou. The aircraft had also received another 10 passengers from an aircraft that had flown from Togo. The boarding was disorderly. Many passengers tried to sit beside their friends and even occupied the cabin jump seats and the cabin crew were overwhelmed. Meanwhile, the flight crew were involved in an argument inside the cockpit as they had not received the basic information on the aircraft's load.

While the cockpit crew were engaged in an argument on the weight and balance, the ground baggage handler was loading the baggage at the aft of the aircraft. One of UTA's agents then asked the handler to load the baggage at the forward hold, which was already filled with baggage. Subsequently, the forward hold was full with baggage. Back in the cockpit, the crew continued to discuss the weight of the baggage. They became more frustrated as there were no information regarding the number of passengers that had boarded the aircraft in Cotonou. It was a tense situation as all the flight crew were unable to determine the exact weight of the baggage of each passengers.

As the Captain decided to discuss the matter with the flight engineer, the First Officer became angry and yelled at the Director General of UTA, who was sitting at the cockpit jump seat across him, due to the absence of information. The UTA executive, however, tried to reason with the First Officer on the matter.

The UTA executive immediately apologized to the crew. He stated that he would tell the management off as soon as the aircraft arrived in Beirut, later added that he would send messages to not allow anymore baggage or luggage weighing more than 30 kilograms. By this time, all passengers had already boarded the aircraft. Fuel was added to both tanks and the flight plan had been filed by the captain. The Captain then configured the aircraft with flaps at 25 degrees. The elevator was set at 6¾ and full power with brakes on would be applied for the take-off, followed by a three-degree maximum for take-off climb. The First Officer was the pilot flying.

The air conditioner was shut down. The weather was hot and dry. Weather report stated that there were cirrus clouds covering the sky and that there were some stratocumulus at an altitude of 1500 ft. The visibility was about 8 km and the humidity was at 75%.

As everything was set, the crew began the take-off roll. However, several passengers were still reluctant to sit down and decided to stand near their friends. This led the chief flight attendant to inform the cockpit crew on the situation. Order was finally restored after the Directorate General of UTA had called for order and the passengers finally decided to sit down on the floor.

At 13:58 local time, the flight crew applied take-off thrust. A few seconds later, the brakes were released. The First Officer was pushing the nose down and the captain was observing the airspeed. The aircraft then reached V1 and subsequently reached its VR speed. An input from 5-degree nose down to 10-degree nose up was made by the First Officer in a span of two seconds. The nose of the aircraft, however, remained constant and the speed continued to increase.

The Captain became anxious as the aircraft's wheel had not lifted off the runway. He then called for rotation at least twice. The First Officer then pulled the yoke even harder so the aircraft could take-off. The angle of attack then changed from −1.2-degree to a maximum of +9-degree, at a speed of 1 degree per second.

The aircraft finally managed to lift off at 13:59:07 for a negligible altitude. Realizing that they were going to run out of runway, the captain urged the first officer to pull harder.

At 13:59:11, the aircraft struck the localizer antennas at the end of the runway. The aircraft's main landing gears then impacted the localizer building, causing the roof to fly for approximately 9 meters from the point of impact. The right main landing gear then detached. The impact subsequently caused small parts of the tail and the aircraft's stair to detach as well. The aircraft then impacted the airport's concrete boundary fence, scraping the lower part of the fuselage and caused some parts of the flaps to separate from the wings.

The aircraft then slid and struck a rainwater drainage canal located right after the perimeter fence. The collision damaged the aircraft's landing gears and parts of its wings. The leading edge and the outer aileron from the right wing then separated from the airframe. A survivor who was seated at the rear of the aircraft stated that people flew off their seats and, at the moment of impact, "fly around the cabin". According to testimonies, some passengers had not attached their seatbelts.

After it had struck the drainage canal, the aircraft broke up into three parts; the cockpit section, the fuselage, and the tail of the aircraft, all of which ended up in the sea. The majority of the fuselage managed to stay intact however, the fuselage became upside down due to the impact, drowning the occupants inside. Those who were seated near the breaks were able to get out of the sinking wreckage.
