Faucett Perú Flight 251 was a scheduled domestic flight from Lima to Juliaca, operated by the Peruvian airline Faucett Perú. On February 29, 1996, while flying in the Andes Mountains, the Boeing 737 encountered worsening weather conditions. After departing from Lima, the aircraft faced extreme turbulence and reduced visibility as it approached its destination. The crew attempted to navigate through these dangerous conditions, but tragically lost control of the aircraft. The plane ultimately crashed into the mountains, resulting in the death of all 123 individuals on board, including passengers and crew members. The aftermath of the crash prompted investigations into the airline's practices and air traffic control procedures in the region.

The search and rescue operation faced significant challenges due to the remote and rugged terrain of the Andes. Rescuers struggled to access the crash site, which delayed initial retrieval efforts and increased the complexity of the investigation. Investigators delved into factors such as weather reports, pilot training, and aircraft maintenance, seeking to uncover the precise causes of the disaster. The final reports highlighted the need for stricter regulations and improved training for pilots flying in hazardous mountainous areas, ultimately influencing flight safety policies across the aviation industry.
