Requirement: 1. Inspect all affected batteries for signs of cracking in the external case.\n\n2. Replace battery.\n\nNote: If electrolyte leakage has occurred, neutralisation and assessment of the damage to the affected area is to be carried out by a Licensed Aircraft Maintenance Engineer.\n\nCompliance: For Para 1: Upon receipt of this directive and thereafter at each Daily Inspection until the battery is replaced.\n\nNote: This inspection may be accomplished by the Pilot in Command, in which case the pilot shall enter and certify for this A.D. in Col. 2 Part 3 of the maintenance release on each occasion.\n\nFor Para 2: Upon detecting a cracked battery or within 50 hours time in service after 30 June 1984 if the battery is found serviceable after compliance with Para 1.\n\nBackground: The manufacturer has issued a recall notice for these batteries due to problems being experienced with the epoxy resin used to seal them. Several occurrences of case failure with this battery have been reported. The affected batteries have been discontinued and represent the final production batch made by the manufacturer.","sortOrder":0}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":2306},"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"The directive maintains its original targeted scope addressing the specific manufacturing defect in the identified battery batch.
