S10 FAA AD Pressure Sensor Inspection

Docket No. FAA-2007-28958; Directorate Identifier 2007-CE-070-AD; Amendment 39-15227; AD 2007-21-09

We are adopting a new airworthiness directive (AD) for the products listed above. This
AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: As a result of a fault report from a Stemme S10-VT operator, an investigation of the differential fuel pressure sensor 11AB-K01 was performed. The fault report describes a fuel leak through the air pressure line into the airbox. The fuel escaped through the drainage tubes. As a result of this investigation, the possibility of a leak to the engine compartment cannot be excluded. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
