Emergency Landing of Piper PA-28-180 EC-BFO in Cuenca

Incident Overview and Flight Details On December 18, 2003, a Piper PA-28-180 with registration EC-BFO, operated by a commercial pilot and flight instructor, made an emergency landing in the municipality of Zarzuela, Cuenca. The aircraft was equipped with a single Lycoming IO-360-A3A engine. The pilot, who had approximately 800 total flight hours and 500 hours on type, was returning the aircraft to Madrid-Cuatro Vientos after an instructional flight. The flight was filed under IFR rules, with a transition to VFR planned. ## Weather and Operational Context The pilot had delayed the departure due to poor weather conditions at Madrid-Cuatro Vientos, filing multiple flight plans throughout the morning. The aircraft departed Valencia around 13:00 UTC. During the cruise phase, the pilot reported being between clouds and requested a lower flight level, but was denied due to minimum altitude restrictions. At 14:14 UTC, the pilot reported difficulty maintaining altitude and was authorized to descend at discretion. ## Icing and Emergency Declaration While at Flight Level 070, the pilot observed ice formation on the leading edges of the wings, particularly the left wing, which degraded performance and caused an accelerated loss of altitude. The pilot had the pitot heat on and also observed ice on the windshield. At 14:21 UTC, a relay aircraft reported that EC-BFO was icing, passing 6,000 feet, and descending. Radar contact was lost at 14:21:59 UTC. The pilot declared an emergency and squawked 7700. ## Emergency Landing and Aftermath The pilot located a narrow, clear rural road and executed an emergency landing. The right wingtip struck an embankment, and the aircraft veered off the road into a field. The pilot sustained minor contusions and abrasions and was later discharged from a hospital the same night. The aircraft sustained substantial damage to the propeller, wings, and landing gear. No mechanical failures were reported prior to the accident, and the engine, navigation, and altimetry equipment functioned throughout the flight. ## Meteorological Conditions Weather data indicated that the freezing level over the accident area was approximately 6,500 feet, with temperatures ranging from 2°C at 6,000 feet to -5.5°C at 10,000 feet. The pilot reported no precipitation during the final cruise phase. No other pilots reported icing conditions in the area that day.
