machine
The aircraft concerned was a Boeing 737-73V, which was seven years and seven months old at the time of the accident. The final assembly of the aircraft was completed at the Boeing plant in Renton , Washington State, and completed its maiden flight on January 10, 2003 with the test number N6046P . The aircraft had the factory number 32416 and the serial number 1270 . The machine was built for the aircraft leasing company AWAS and delivered brand new to their customer Easyjet on February 21, 2003 , where it was put into operation with the aircraft registration G-EZJU . After the lease had expired, the machine was phased out on January 27, 2010 and stored at London Southend Airport . The machine was then leased from AWAS to AIRES and approved with the new registration number HK-4682 . The delivery flight took place between March 6 and 7, 2010, the machine was initially flown from London Southend Airport to Santa Maria Airport on the Azores . This was followed by a stopover at Las Américas Airport near Santo Domingo in the Dominican Republic , until the plane finally reached Bogotá Airport as its destination. The twin-engine narrow-body aircraft was equipped with two Turbojettriebwerken type CFMI CFM56-7B20 equipped. By the time of the accident, the machine had completed a cumulative total operating performance of 23,485 operating hours.

Overview map of flight route |
There was a six-person Colombian crew on board, consisting of a flight captain, a first officer and four flight attendants.
- The 43 year old flight captain Wilson Gutierrez was the pilot flying . He had obtained his commercial pilot license on November 19, 1991. He was first employed by an airline as the first officer on board the Douglas DC-3 , later he flew as the first officer in the cockpit of a privately owned PBY6A Catalina . In 1998 he started flying for AIRES, where he was deployed on the Embraer EMB 110 for three and a half years . From 2001 to 2005 he was first officer on board the De Havilland DHC-8 . He was then promoted to captain of this type of machine, a position he held until December 2009. Gutierrez was trained as first officer and then pilot of the Boeing 737-700 only eight months before the accident. The captain had 7,643 hours of flight experience, 343 of which he had with the Boeing 737.
- The 25-year-old first officer Camilo Piñeyros Rodriguez was the monitoring pilot . He began his pilot career in 2006 and was first officer in the cockpit of the De Havilland DHC-8 for two years before he was trained as first officer in the cockpit of the Boeing 737 in August 2009. The first officer had 1,900 hours of flight experience, 800 of which he had completed in the cockpit of the Boeing 737.

The approach to the airport on the remote Colombian island of San Andrés , 190 kilometers off the coast of Nicaragua , was carried out at night and during a storm. The captain flew the aircraft configured for the landing 49 meters from the runway into the area. The Boeing hit the ground hard, center fuselage first, and slid straight ahead 100 meters onto the runway while turning 90 degrees to the right. The fuselage broke into three parts, all of which came to a standstill on the runway. The front fuselage section, consisting of the cockpit and the first eight rows of seats, pointed in its end position in a different direction than the other two parts of the main wreck. In the accident, the landing gear and an engine were also torn off the machine.
Victim
Two people were killed of the 131 inmates: A 68-year-old woman suffered a tear in the aorta and a tear in the liver in the impact and died from these injuries. One girl also suffered severe brain damage from which she also died 16 days after the accident. Four other people were seriously injured. Of the surviving inmates, 119 people were taken to the hospital for examination, but most had only minor injuries. A total of 13 people, including the four seriously injured, were flown to Bogotá for further treatment .
root cause
It was found that the aircraft had been flown below the approach profile during the entire approach. The captain stated that instead of following the PAPI lights, he had watched the green lights on the runway threshold. On approach he had aimed at the start of the landing threshold instead of the touchdown point. In doing so , he had been guided by a routine that resulted from his flight experience with turboprop aircraft , but which did not correspond to the recommendations for steel-powered passenger aircraft such as the Boeing 737.
Investigations revealed that the airline had not hired new pilots when it expanded rapidly in 2009 and added nine Boeing 737s to its fleet. Instead, the pilots who were employed by the company and were mainly experienced in flying turboprop aircraft were trained on the aircraft type that was newly added to the fleet portfolio. The captain, who is mainly experienced in flying DHC-8 turboprop aircraft, was deployed in Boeing 737s after only five weeks of training; the first officer had only completed a two-week training course.
However, a deception of the pilot's sensory perception was found to be the main cause of the accident. During the approach during the night and without reference points next to the illuminated runway, the pilot had the impression that the machine was closer to the runway than it was. For this reason he had steered the machine to a point in front of the runway.
