AD 2007-19-12 Airworthiness Directives; SICMA Aero Seat 50XXX Passenger Seats

This AD applies to SICMA Aero Seat 50XXX passenger seats with part numbers listed in the following Table 1: Table 1.—Applicability Single seats Part No. Twin seats Part No. 50692(xx)-(xx) 50A71(xx)-(xx) 50442(xx)-(xx) 50A81(xx)-(xx) 50752(xx)-(xx) 50401(xx)-(xx) 50402(xx)-(xx) 50451(xx)-(xx) 50462(xx)-(xx) 50391(xx)-(xx) 50392(xx)-(xx) 50452(xx)-(xx) 50382(xx)-(xx) 50A02(xx)-(xx) 50A72(xx)-(xx) 50A82(xx)-(xx) These seats are installed on, but not limited to, Boeing 747, 767, and 777 series, and Airbus A330 and A340 series airplanes. Reason (d) Direction Generale De L'Aviation Civile (DGAC) Airworthiness Directive F-2005-135, dated August 3, 2005, states: A release of smoke was experienced in the passenger compartment during flight after an overheating of a reading lights power box of a PN 5039201-4T SICMA seat. An analysis put into evidence that this overheating was caused by a short-circuit produced by the rupture of an electrical power supply component (PN 78147-B). It has been noticed that this power supply is not in compliance with DO 160 environmental standard. The short-circuiting could result in arcing and consequent smoke or fire. We are issuing this AD to prevent a short-circuit in the power box, which could result in smoke or fire in the airplane cabin.

Unless already done, within six months from the effective date of this AD, identify the seats part numbers listed in the Table 1 of this AD and replace installed reading lights electrical power supplies with new ones using the instructions of the SICMA Aero Seat Service Bulletin No. 50-25-210, dated June 27, 2005.
