The fixes involve:\n- Installing extra protection around wire bundles (to prevent electrical arcing/sparking)\n- Replacing wiring that is too thin/undersized for the electrical load it carries\n\n**Who it affects:**\nAnyone who owns or operates Boeing 737 model aircraft covered by two specific Boeing Service Bulletins (technical notices) from 1991.\n\n**Why it matters:**\nThere had been **reports of arcing (electrical sparks) and smoke** coming from this panel, plus discovery of wiring that couldn't safely handle the electrical current. This creates fire and electrical failure risks. The directive makes these repairs compulsory before a deadline to keep the aircraft safe to fly.\n\n**Key deadline:**\nAll required work must be completed before 25 November 1992."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The directive maintains the original corrective scope: it mandates remediation of identified arcing/smoke risks and undersized battery-bus wiring on the P6 Load Control Centre for the specific Boeing 737 airframes listed in the Boeing service bulletins.
