SAIB Issued for Zodiac CH601XL and CH650 Light Sport Aircraft

FAA issued a Special Airworthiness Information Bulletin (SAIB) on November 7, 2009, to address an airworthiness concern on all variants of Zodiac CH601XL and CH650 airplanes. FAA conducted a special review to evaluate possible in-flight structural failures believed to be the cause of five accidents since 2005. The review determined that rather than a single root cause, the accidents implicate a potential coupling of design and operational aspects of the aircraft.

Among the areas of concern: wing structure, structural stability, flutter, airspeed calibration, and stick force characteristics. FAA recommends all owners and operators of Zodiac CH601XL/CH650 airplanes comply with actions outlined in an Aircraft Manufacturing & Design, LLC (AMD) Safety Alert /Safety Directive before further flight.
