AD NUMBER: 2007-19-12
MANUFACTURER: Seats
SUBJECT: Airworthiness Directive 2007-19-12
SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from Mandatory Continuing Airworthiness Information (MCAI) provided by the aviation authority of France to identify and correct an unsafe condition on SICMA Aero Seat 50XXX Passenger Seats. The MCAI states the following: A release of smoke was experienced in the passenger compartment during flight after an overheating of a reading lights power box of a PN 5039201-4TSICMA seat. An analysis put into evidence that this overheating was caused by a short-circui tproduced 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 proposing this AD to prevent a short-circuit in the power box, which could result in smoke or fire in the airplane cabin.
