A Fokker 100, registration PR-OAF, experienced a landing accident at Bras¡lia-Presidente Juscelino Kubitschek International Airport (BSB) on February 26, 2024, resulting in significant damage to the aircraft. The flight, operating a scheduled domestic passenger flight from Petrolina to Bras¡lia, suffered a loss of pressure in the hydraulic system during en route operations. Upon approaching Bras¡lia, the flight crew initiated an alternative system to lower the undercarriage, which resulted in the main landing gears locking and the nose landing gear not lowering. The aircraft landed on runway 11R, with a total landing distance of 900 meters. Initial landing conditions were challenging, with the aircraft supporting only the main landing gears and then the lower part of the front fuselage. Following coordination with air traffic control, the aircraft was instructed to land on runway 11R. Subsequent damage to the aircraft’s structural elements near the nose was observed, primarily due to a restriction on the articulation movement of the right nose landing gear door, coupled with the weight of the landing gear exceeding its articulation capacity. The maintenance records indicated a potential issue with the hinge mechanism, specifically a restriction that allowed for deviation in the door’s movement, potentially leading to corrosion and subsequent damage. Furthermore, the modification of the landing gear hinges, including larger radial pins and widened lobe holes, may have contributed to the corrosion and subsequent failure of the EDP1 gasket. The hydraulic system failure was likely caused by an extrusion of the EDP1 gasket, resulting in hydraulic oil leakage.A Fokker 100, registration PR-OAF, experienced a landing accident at Bras¡lia-Presidente Juscelino Kubitschek International Airport (BSB) on February 26, 2024, resulting in significant damage to the aircraft.
