Paint Options
The BASF Glasurit exterior paint used on all Sikorsky S-333TM helicopters is one of the most technically advanced paints available. It is the same as that used by premium automobile companies such as BMWs and Mercedes. The nine-step paint process offers superior corrosion protection and a durable yet attractive appearance.
Four factory standard trim styles and literally hundreds of colors are available.

Safety and Crashworthiness
From the onset of its development, safety and crashworthiness were central to the S-333TM helicopter design concept. The following safety features are incorporated into the S-333 aircraft.
Safety Features
• Forgiving flight characteristics• No hydraulic systems• Gravity fuel system• Derated, reliable turbine engine• Proven dynamic system with high component lives• Easy inspection of drive train components• Exceptional autorotation characteristics• Fail-safe design features• High ground clearance• Ample engine power reserve under all flight conditions
Crashworthiness Features
• 25 inches of stroke in the landing gear• Cabin subfloor with 16 inches of crushable structure• Forward cabin structure designed to mil-spec plowing loads (energy absorption in longitudinal axis)• Cabin structure provides rollover protection• Raised rotor hub reduces possibility of blade impingement into cockpit • Fire / overheat detector system• Crashworthy fuel bladder designed to mil-spec criteria
