What happened
On October 21, 2022, at approximately 19:00 UTC, a Beechcraft BE-36, registration LV-WNO, was conducting a general aviation ferry flight from Mendoza International Airport to San Fernando International Airport. While the aircraft was in the cruise phase of flight, the pilot received an alert indicating that a door was open.
As a precautionary measure, the pilot elected to divert the flight and land at Brigadier Mayor Ojeda Airport in the province of San Luis. Upon landing and conducting a thorough inspection of the aircraft, the pilot confirmed that the door system was functioning correctly and that there was no actual breach of the cabin integrity.
The investigation
Following the event, the investigation focused on the activation of the door alarm during the cruise phase. The crew performed a technical check of the aircraft's door locking and sensing mechanisms. The investigation established that after verifying the correct operational status of the door and the associated warning system, the flight was able to proceed to its original destination.
