The Lake LA-4 Buccaneer is one of general aviation's most distinctive amphibious aircraft, combining the freedom of water operations with conventional runway capability in a compact four-seat package. Designed by David Thurston and first flown in 1959, the LA-4 series became the most successful American light amphibian of its era, with the LA-4-200 variant introduced in 1970 featuring a 200-horsepower Lycoming IO-360 engine that gave it respectable performance on both elements. The Buccaneer's pusher-propeller configuration, mounted high on a pylon above the cabin, keeps the engine clear of water spray during takeoff and landing, while its all-metal construction and retractable landing gear allow it to operate from grass strips, paved runways, lakes, rivers, and coastal waters with equal ease. This versatility made it popular with bush pilots, island-hoppers, and recreational flyers who valued access to remote waterfront destinations unreachable by conventional aircraft. The type's relatively modest operating envelope reflects its dual-purpose mission: cruise speeds around 120 knots and a service ceiling near 14,000 feet prioritize utility and safety margins over raw performance. Production continued under various owners through the 1980s, and many examples remain active today in float-plane country from Alaska to the Caribbean. SkyMeter has tracked 71 flights across 36 airframes and 36 operators, with IANNONE ANDREW JOSEPH the largest observed operator.

Safety in context

The incident rate counts flights with ANY safety event detected by SkyMeter: go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
