Bilbao

The aircraft was on its final approach to runway 30 of Bilbao Airport. The aircraft, operated by Iberia, was employed on flight IB1456, a scheduled domestic flight from Barcelona to Bilbao, with 136 passengers and 7 crew members on board. The expected flight time was 53 minutes. The current conditions in Bilbao were night VMC, with a 10 knots and southwest (SW) wind and gusts of up to 25 knots. Visibility was more than 10 km and there were scattered clouds above 5,600 feet. The sun had set four hours earlier and all electronic and visual aids in the airport were fully operational. There was no rain and the flight was conducted unter IFR rules. Since the takeoff from Barcelona at 2201LT, the flight had been uneventful. The pilot flying was seated on the right hand side, and he was in line flying under supervision. The captain seated on the left hand side was supervising the flight. A third flight crew member, seated in the jumpseat, was the first officer who had given his seat to the pilot under supervision on the right hand seat. On course to Bilbao, the aircraft flew over Pamplona at FL150, where they were informed of possible light turbulence. A about 25 NM from their destination and at 7,500 feet altitude, they crossed a small cumulus with strong turbulence. Descending through 6,000 feet and established on the Bilbao localizer they found winds of 55 knots. The ATC tower (TWR) of Bilbao cleared them to land on runway 30, and informed the decision height, 247 feet, under VMC conditions and continued the approach to land. One minute prior to touchdown, the tower informed of wind conditions of 240° 8 knots. The aircraft conditions during the approach were: weight, 62,380 kilos; centre of gravity, 28,66% MAC, full flaps. The reference speed (Vref) was 132 knots and the approach speed (Vapp), 142 knots. Autopilot was disconnected by the crew at 400 feet to continue the approach manually. In the last few seconds prior to touchdown, the vertical descent speed was very high, around 1,200 feet per minute (6 metres per second) and the 'sink rate' warning of the GPWS sounded twice. The aircraft did not react to the pitch-up order input applied by both pilots on the side-sticks, due to the design software logic that operates at these specific moments, and did not flare. Announcements of 'dual-input' warning were heard at the time. Then the captain, in view of the 'sink rate' warnings, selected TOGA power setting to go around and abort the landing. The pilot's actions on the flight controls could not avoid a hard touchdown of the aircraft in a slight nose down attitude, and the captain decided to continue the landing and to stop the aircraft. The aircraft slowed-down along 1,100 metres of the runway within the paved surface. It finally came to a stop with its horizontal axis at an angle of 60° to the right of the runway centerline. During the landing roll the nose landing gear collapsed, the four tires of the main gear burst and the engine nacelles, on which the aircraft was leaning after the collapse, dragged along the pavement. Once the aircraft came to a halt, the captain ordered its evacuation, which was carried out using all the exit doors and their slides. During the evacuation a cabin crew member and 24 passengers were injured. All injuries were considered minor except for one, a female passenger whose injuries were considered serious. Seven injured people were taken to hospital.

Iberia Flight 610 departed Madrid at 08:47 for a scheduled flight to Bilbao, where it was scheduled to land at 09:35. The Boeing 727, named "Alhambra de Granada", climbed to the cruising altitude of FL260. At 09:09 the crew were instructed to descend to FL100. Seven minutes later the copilot contacted Bilbao Tower. The controller then cleared the flight for an ILS approach: "Iberia 610, you can continue descent, for an ILS approach to Bilbao, runway 30, wind is 100 degrees 3 knots, QNH 1025 and transition level 70." This was confirmed by the crew. The controller subsequently offered them a direct clearance to the approach fix, which is located at 13 DME from the airport. The captain declined and decided to fly the standard approach procedure. At 09:22 flight 610 reported over the Bilbao VOR at 7000 feet, starting the standard approach procedure. The airplane further descended to 5000 feet, which it reached three minutes later. The crew switched the Altitude Alert System to 4300 ft (the minimum sector altitude is 4354 feet) and continued the descent. The altitude alert horn sounds 900 feet prior to reaching the preset altitude (approach mode) and 300 feet below that altitude (deviation mode). Since the flight had 700 feet to go, the horn would only sound at around 4000 feet. Since the crew descended below the minimum sector altitude, the altitude alert horn sounded at 4040 feet. The crew interpreted this being the approach mode alert, and continued their descent. Fifty-seven seconds after passing through the minimum sector altitude, the airplane struck the base of a structure of antennas located close to the top of Mount Oiz (3356 feet high). The left wing broke off and the remaining fuselage crashed onto the hillside, cutting a swath through the trees. The aircraft disintegrated on impact and all 148 occupants were killed.

While descending to Madrid-Barajas Airport inbound from Bilbao, the crew encountered poor weather conditions with clouds, rains showers and turbulences. Twice, the airplane suffered downdrafts and the second time, it lost 800 meters in few seconds and eventually hit the slope of the peak Lobo-Cebollera located east of Somosierra. A crew member was able to find help and rescuers arrived quite quickly on site. Ten people, including 4 crew members, were injured while 23 other occupants were killed.

The twin engine airplane departed Biarritz-Parme Airport on a flight to Bilbao, carrying three passengers and two crew members. While cruising over the Basque County, the airplane was shot down by the pilot of a Spanish Nationalist Forces fighter and the engines were struck by bullets. The crew reduced his altitude and attempted an emergency landing when the aircraft crash landed on a beach located in Sopelana, about 12 km northwest of Bilbao Airport. The aircraft was destroyed and all five occupants were injured.

The airplane was engaged in a bombing mission over Bilbao when it was shot down by the pilot of a National Air Forces fighter. It entered a dive during which two crew members were able to bail and eventually crashed in Arraiz, in the suburb of Bilbao, bursting into flames. The three crew members who remained on board were killed.
