What happened
On June 25, 2005, at approximately 12:00 UTC, a Cessna 172N seaplane, registration I-PVLC, was conducting a recreational flight over Lake Como. While the aircraft was near the northern part of the lake, the pilot contacted the local radio station to report an intended landing. At that time, weather conditions were deteriorating rapidly, with winds exceeding 40 knots and an approaching thunderstorm accompanied by hail.
Following radio advice from Aero Club Como instructors flying in the same area, the pilot attempted a precautionary landing near Isola Comacina to reach the shore quickly. The aircraft successfully landed on the water; however, as the aircraft entered the floating phase, a violent thunderstorm developed suddenly. The resulting rough water surface and high winds caused the aircraft to lose directional control. The wind forced the left wing to impact the water surface, leading to the capsizing of the aircraft.
The investigation
The ANSV investigation examined the meteorological conditions, the aircraft's mechanical state, and the sequence of the landing maneuver. The investigation confirmed that the aircraft had undergone a configuration change from landplane to seaplane earlier in 2005 and had passed its 50-hour inspection the day before the accident. Investigators focused on the impact of the rapidly changing weather on the pilot's ability to maintain control during the floating phase of the landing.
Findings
- The primary cause of the accident was the loss of directional control by the pilot during the floating phase of the landing.
- A significant contributing factor was the sudden deterioration of meteorological conditions, which created a rough water surface and caught the pilot by surprise while approaching the shore.
