Compliance: At the next annual inspection, but no later that 100 hours time in service or 12 months after the effective date of this Directive, which ever occurs first.
This Airworthiness Directive becomes effective on 20 March 2003.
Background: Incidents of the cigar lighter unprotected electrical wiring shorting have been reported overseas. This Directive requires either the deactivation of the cigar lighter or the installation of a circuit protection device. These measures are designed to prevent an in-flight electrical system failure, smoke in the cockpit, and/or fire in the wire bundle behind the instrument panel.
