What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Airman privacy data omitted was conducting a series of pattern circuits for proficiency in an amphibious Cessna 206. privacy data omitted Recently changed his procedure of, previously, leaving landing gear down whilst in the pattern to that of always and immediately retracting gear as the consequences of a water landing with gear down is often catastrophic.
During the final circuit privacy data omitted ran his checklist as he usually does but failed to note that the gear was actually up. His installed electronic gear advisory signaled too late to recover. The aircraft remained on the runway and suffered minor damage to the float skid plates.
