If the RAT does not fully deploy during the operational test at Requirement 1\\. This amendment becomes effective on 8 October 1998.\n\nBackground: Several instances of corroded RAT actuators have been found and there has been a case of failure of the RAT to deploy due to a corroded actuator. This Directive mandates a US FAA AD which requires a regular operational test of the RAT for correct deployment. This amendment revises the follow up test compliance requirements.\n\nThe original issue of this Directive became effective on 5 December 1996.","sortOrder":0}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":2471},"content_quality":"ok","complexity_score":3,"scope_assessment":{"changed":false,"description":"This amendment revises the compliance timeframe for follow-up testing (changing from the original 1996 schedule) but maintains the original scope addressing RAT actuator motor corrosion.
