Inspect all seat belts to determine if they have been manufactured by the EON Corporation under TSO C22. These are to include all seat belts supplied under an airframe manufacturers part number.\n\n    2. If the seat belt assembly is an EON Corporation seat belt assembly determine if an E6000 buckle is fitted. If an E6000 buckle is fitted remove the seat belt assembly and replace with another item approved in accordance with ANO 108.42.\n\n    3. The seat belts removed in compliance with this Directive are to be destroyed or have the TSO markings removed or totally obliterated.\n\nNote: This type of buckle assembly has a front cover plate which is pivoted at one end and is pulled at the other end through an arc to release the latch from the buckle. The E6000 buckle assemblies can be identified by the type of catch they use. Figure 1 shows the configuration of the catch and how it is located within the buckle assembly.\n\n![](image.002.png)  \n\nNote: FAA AD 87-04-19 refers.\n\nCompliance: Prior to the issue of the next Maintenance Release after 4 June 1987 and thereafter prior to the issue of a Certificate of Airworthiness.\n\nBackground: This Directive is prompted by reports of a buckle assembly that pulled apart under load and of other assemblies that could be pulled apart by manipulating the latch in the buckle. This could result in lack of restraint during either flight or crash loads.\n\nCOMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 \\- 107 CIVIL AVIATION SAFETY AUTHORITY\n\nSCHEDULE OF AIRWORTHINESS DIRECTIVES","sortOrder":0}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":2303},"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"The directive maintains a narrow, targeted scope focused exclusively on the specific defective E6000 buckle assembly identified as a safety hazard, without expansion into broader seat belt certification requirements."},"complexity_factors":["Simple three-step procedural requirement without nested conditions or exceptions","No defined terms section or interpretation provisions","Minimal cross-referencing (only to FAA AD 87-04-19 and ANO 108.42)","Clear visual identification method provided (Figure 1)"],"plain_english_summary":"This mandatory Airworthiness Directive requires operators to inspect all aircraft seat belts, remove any Eon Corporation E6000 buckles that can unexpectedly release under load, replace them with approved alternatives, and destroy or deface removed belts so they cannot be reused.
