Aeroperú Flight 603 was a scheduled commercial flight operated by Aeroperú, which took off from Jorge Chávez International Airport in Lima, Peru, en route to Santiago, Chile. Shortly after takeoff, the Boeing 757 experienced a catastrophic failure that resulted in its descent into the ocean. Among the 70 individuals on board, all were lost in the tragedy, marking one of the deadliest incidents in the nation's aviation history. The aircraft lost contact with air traffic control about four minutes after departure, leading to an immediate and extensive search operation involving naval and aerial teams.

Investigations conducted by Peruvian authorities and the U.S. National Transportation Safety Board uncovered several contributing factors to the crash. The malfunction of the altimeter, which provides pilots with altitude information, was central to the incident, with evidence suggesting that the aircraft was flying too low after takeoff. Pilot error, combined with technical malfunctions, highlighted significant flaws in operational procedures. The findings raised awareness regarding the importance of aircraft maintenance and the need for strict adherence to safety protocols in aviation.

The aftermath of the crash led to significant changes in Peruvian aviation regulations. The incident initiated discussions about the need for stricter oversight of airlines and their maintenance procedures in Peru, ultimately leading to better training for pilots and improvements in technology used in aircraft. It also spurred international attention on aircraft safety standards, reinforcing the necessity of ongoing vigilance in flight operations worldwide.
