Narrative:
Landed wheels up in aircraft equipped with amphibious floats. Immediate cause was distraction by low-level turbulence and failure to check wheel status. Float installation could be improved by addition of gear status indicator lights on panel (now lacking and not included with float kit provided by manufacturer). Owing to the need to match gear position with surface (landing) medium such an indicator is of high importance on amphibians. Fortunately, a gear up landing on floats is almost a non-event. No damage done to aircraft or pilot, and raising the plane to lower wheels takes about 5 mins due to light weight. Nevertheless, a light system would help overcome the effects of similar future distrs, which are sure to occur.
Original NASA ASRS Text
Title: A RANS S-7 EQUIPPED WITH FLOATS LANDED WHEELS UP DUE TO PLT DISTR WITH LOW LEVEL TURB AND FAILURE TO CHK WHEEL STATUS.
Narrative: LANDED WHEELS UP IN ACFT EQUIPPED WITH AMPHIBIOUS FLOATS. IMMEDIATE CAUSE WAS DISTR BY LOW-LEVEL TURB AND FAILURE TO CHK WHEEL STATUS. FLOAT INSTALLATION COULD BE IMPROVED BY ADDITION OF GEAR STATUS INDICATOR LIGHTS ON PANEL (NOW LACKING AND NOT INCLUDED WITH FLOAT KIT PROVIDED BY MANUFACTURER). OWING TO THE NEED TO MATCH GEAR POS WITH SURFACE (LNDG) MEDIUM SUCH AN INDICATOR IS OF HIGH IMPORTANCE ON AMPHIBIANS. FORTUNATELY, A GEAR UP LNDG ON FLOATS IS ALMOST A NON-EVENT. NO DAMAGE DONE TO ACFT OR PLT, AND RAISING THE PLANE TO LOWER WHEELS TAKES ABOUT 5 MINS DUE TO LIGHT WT. NEVERTHELESS, A LIGHT SYS WOULD HELP OVERCOME THE EFFECTS OF SIMILAR FUTURE DISTRS, WHICH ARE SURE TO OCCUR.
