Incident Overview
On February 9, 2016, a Piper PA-60-602P, registration CX-RHS, departed from Laguna del Sauce Airport (Punta del Este) bound for SADF with five persons on board. Shortly after reaching an altitude of 300 feet, the right engine fire alarm became both audible and visible. The crew addressed the alarm and subsequently landed the aircraft on a single engine.
Investigation Findings
An inspection of the right engine revealed no evidence of actual fire. Investigators discovered oil residue from the air conditioning system, which had triggered the false fire alarm. The aircraft's right flap showed soot on both sides, consistent with extinguishing agent splatter.
Conclusion
The event was classified as an incident, not an accident or serious incident, under national and international regulations. No safety recommendations were issued.
