Investigation Summary
The disaster occurred as Alianza Lima, then leading the Peruvian league, was returning from a victory in Pucallpa. During the descent into Lima, the cockpit indicator for the nose landing gear failed to show a 'down and locked' status. The crew performed a low fly-by of the tower, where observers confirmed the gear appeared to be down. However, the crew remained uncertain. The captain, Lieutenant Edilberto Villar, instructed the co-pilot to consult the emergency manual. Because the manual was in English and the co-pilot had limited proficiency in the language, he struggled to communicate the correct procedures. During the subsequent turn over the ocean to line up for a second landing attempt, the aircraft descended too low in the darkness. The right wing struck the water, causing the aircraft to break up and sink. While only the pilot was ultimately rescued, reports indicate that three people initially survived the impact, including player Alfredo Tomassini. Tomassini, suffering from a broken leg, floated with Villar for several hours using improvised flotation devices but eventually drowned in the choppy waters before dawn.
Final Conclusions
The investigation, which remained suppressed by the Peruvian Navy for nearly two decades, concluded that the primary cause was pilot error compounded by mechanical negligence. The pilot lacked sufficient night-flying experience, having logged no night hours in the 30 days prior to the crash. Furthermore, the aircraft was dispatched with known defects, including a malfunctioning radar altimeter and a worn landing gear indicator switch. The crew's inability to effectively use the English-language flight manual under pressure led to a loss of situational awareness, resulting in a controlled flight into the water.

Airframe & Maintenance
Systems & Failure Modes
Nose Landing Gear Indicator
A worn switch caused a false indication that the gear was not locked, triggering the emergency sequence.
Radar Altimeter
The unit was reported to be oscillating, preventing the pilots from accurately judging their height above the water in darkness.
Flight Manual
The manual was written in English; the co-pilot's poor language skills led to a misinterpretation of emergency procedures.
