This AD results from evaluation of the carbon resistor, which revealed a failure mode that can cause the resistor to ignite, involving adjacent capacitors as well. The Federal Aviation Administration is issuing this AD to prevent a standby static inverter from overheating, which could result in smoke in the flight deck and cabin and loss of the electrical standby power system. Modification (f) At the time specified in paragraph (f)(1) or (f)(2) of this AD, as applicable: Modify the static inverter by removing resistor R170 from the logic control card assembly and replacing it with a new resistor, and relocating the new resistor to the solder side of the printed circuit board, in accordance with the Accomplishment Instructions of the applicable service bulletin specified in Table 1 of this AD, except as provided by paragraph (g) of this AD. (1) For Model 737, 757, and 767 airplanes: Within 42 months after the effective date of this AD. (2) For Model 747 and 777 airplanes: Within 60 months after the effective date of this AD. (g) For Group 2 airplanes identified Boeing Special Attention Service Bulletin 767-24-0160, dated June 30, 2005: Airplanes having a static inverter with part number S282T004-2, S282T004-3, or S282T004-4, are not required to do the modification specified in paragraph (f) of this AD.
