What happened
On June 10, 2006, at approximately 08:45 UTC, a S.A.I. F.4 Rondone, registration I-BAZZ, was conducting a series of educational flights for aerospace engineering students at Palermo Boccadifalco Airport (LICP). The flight, operated by a private party, departed from runway 35 at 08:31 UTC.
During the approach to runway 17, the aircraft landed without the landing gear being extended. The fuselage made contact with the runway surface, and the aircraft slid for approximately 60 meters before coming to a complete stop. There were no injuries to the two occupants on board, who were able to exit the aircraft independently. The aircraft sustained damage to the flaps, the propeller tips, the main gear wheel fairings, and the lower fuselage.
The investigation
The ANSV investigation established that the flight was originally scheduled to use a different aircraft, a P.66B with fixed landing gear. However, due to the unavailability of that aircraft, the pilot elected to use the I-BAZZ, which is equipped with retractable gear.
Meteorological conditions at the time of the landing were favorable, with visibility exceeding 10 km and light winds. The investigation focused on the pilot's actions during the landing sequence and the transition between aircraft types.
