Note: This airworthiness directive (AD) applies to each product identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For products that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must use the authority provided in paragraph (e) to request approval from the Federal Aviation Administration (FAA). This approval may address either no action, if the current configuration eliminates the unsafe condition, or different actions necessary to address the unsafe condition described in this AD. Such a request should include an assessment of the effect of the changed configuration on the unsafe condition addressed by this AD. In no case does the presence of any modification, alteration, or repair remove any product from the applicability of this AD.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Aerospace Lighting Corporation (ALC) lamp connectors and fluorescent lamps, that currently requires an inspection, and adjustment or replacement of improperly installed, damaged, or improperly configured lamp connectors and fluorescent lamps used in cabin fluorescent lighting systems. This amendment adds an optional replacement of certain power units and power supplies with new technology parts as terminating action to the repetitive inspections. This amendment is prompted by the availability of new technology components. The actions specified by this AD are intended to prevent smoke, fire, electrical shock, and possible electromagnetic interference caused by high voltage arcing in the cabin which, if undetected, could result in personal hazard or loss of the aircraft.
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.
