2008-12-11: We are adopting a new airworthiness directive (AD) for Agusta S.p.A. Model A109E, A109S, and A119 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The European Aviation Safety Agency (EASA), the technical agent for Italy, with which we have a bilateral agreement, states in the MCAI: During a ground test of the emergency door release system, the Pilot doors failed to disengage. Investigation determined that the reason of this malfunction is interference between the lower hinge and the fuselage structure. This condition, if not corrected, creates the risk of non-disengagement of the Pilot- and/or Co-pilot doors during an emergency, inhibiting the evacuation of the aircraft, possibly resulting in injuries to the occupants. This AD requires actions that are intended to address the unsafe condition caused by interference between thepilot or co-pilot door lower hinge and the fuselage structure.

2008-11-20: We are adopting a new airworthiness directive (AD) for the products listed above that will supersede an existing AD. 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: AD 2007-0315-E was issued to address a possible fuel leakage in the gear compartment in front of the engine and mandated inspections and replacement of fuel plastic-made connectors by connectors made of metal. Since its publication, another fuel leakage has been reported on a S10-VT which had implemented the STEMME Service Bulletin (SB) A31-10-082 as required by AD 2007-0315-E. It has been determined that the fuel leak may have been caused by the deformation that the originally installed clamps created on the fuel hoses and thus preventing the new clamps from being sufficiently pinched to perform a correct tightening.This AD requires actions that are intended to address the unsafe condition described in the MCAI. DATES: This AD becomes effective June 23, 2008. On June 23, 2008, the Director of the Federal Register approved the incorporation by reference of STEMME F & D Service Bulletin A31-10-083, Am-Index: 01.a, dated February 26, 2008, listed in this AD.
