What happened
On December 12, 2012, a Piper PA-34-200T, registration HK-4477G, departed Cúcuta, Colombia, for a planned flight to Barranquilla. The flight was being conducted under Visual Flight Rules (VFR) with one pilot and three passengers on board.
At approximately 15:22Z, the pilot reported crossing the "La Cuchilla" area at 3,500 feet while climbing, stating an intention to report passing Ocaña. Shortly thereafter, air traffic controllers attempted to contact the aircraft multiple times without success, leading to the declaration of an uncertainty phase (INCERFA). Following a search and rescue coordination, the aircraft's Emergency Locator Transmitter (ELT) activated at 16:30Z, confirming the accident in a mountainous region near Vereda Alicia, Zulia. The impact occurred at an elevation of approximately 4,927 feet. All four fatalities were confirmed at the scene.
The investigation
The GRIAA investigation established that the aircraft struck the terrain with a slight right bank and a nose-up attitude. The impact was severe enough to cause total destruction of the airframe, though no post-impact fire occurred. Investigators found that the engines were producing power at the moment of impact.
While the aircraft was equipped with modern navigation tools, including a Bendix/King KLN90B GPS, the investigation noted that the pilot had not received specific training in Crew Resource Management (CRM) or CFIT prevention strategies. Furthermore, although local weather reports indicated visibility was generally good, witnesses near the crash site reported heavy cloud cover that obscured the surrounding mountains.
Findings
- The primary cause of the accident was a controlled flight into terrain (CFIT) during VFR operations in mountainous terrain under low cloud conditions.
- The pilot likely experienced spatial disorientation due to poor visibility and low cloud ceilings.
- There was a lack of adequate flight planning regarding safe altitudes and terrain clearance for the specific route.
- The pilot demonstrated an excess of confidence when attempting to navigate a route requiring strict VFR compliance in challenging terrain.
- A lack of specific training in CFIT avoidance and CRM contributed to the error in decision-making, specifically the failure to declare an emergency or return to the departure airport when visual contact with the ground was lost.
