Boeing Model 777-200 and -300 Series Airplanes
This AD applies to Boeing Model 777-200 and -300 series airplanes, certificated in any category; as identified in Boeing Special Attention Service Bulletin 777-33-0025, dated September 1, 2004.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This AD requires replacing the existing halogen lamps in the cargo compartment light assemblies with new incandescent lamps, and installing warning and identification placards. This AD is prompted by a report of an aft cargo fire during flight. We are issuing this AD to prevent a fire in the cargo compartment.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 18 months after the effective date of this AD, replace all halogen lamps in the cargo compartment ceiling light assemblies with new incandescent lamps that have the part number (P/N) in paragraph (f)(1) of this AD or that meet the standard in paragraph (f)(2) of this AD; and install warning and identification placards. Except as provided by paragraph (f)(2) of this AD, do all actions in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-33-0025, dated September 1, 2004.
(1) General Electric (P/N) GE2233 lamp, as referenced in Boeing Special Attention Service Bulletin 777-33-0025, dated September 1, 2004.
(2) Any 28-volt incandescent lamp built to American National Standards Institute (ANSI) 2233 specifications, and whose manufacturer has requested and been assigned the ANSI 2233 designation by the American National Standards Institute.
Note 1: Boeing Special Attention Service Bulletin 777-33-0025, dated September 1, 2004, refers to Honeywell International Service Bulletin 15-0712-33-0001, dated October 15, 2004, as an additional source of service information for replacing the lamps.
As of 18 months after the effective date of this AD, no person may install a halogen bulb, P/N 9203 (Boeing), or P/N 55-2181-7 (Honeywell), in any airplane cargo ceiling light assembly (excluding the lamp in the airplane's bulk cargo door sill).
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
