This directive was issued to prevent accidents by ensuring the regulator operates correctly.\n\n**Note:** This references a corresponding US Federal Aviation Administration (FAA) directive (AD 68-14-1), showing Australia adopted or aligned with American safety standards for this issue."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The directive's scope is limited and specific in the text: it targets Model E95 aircraft fitted with the Beech Pneumatic De-icer System and Beech model B5 autopilot, requires action per Brittain Industries Inc.

A) shifts technical complexity to that document and to maintenance organisations (Requirement).","Cross-reference to FAA AD adds a jurisdictional cross-link but does not materially complicate the directive's mechanics (Note)."],"plain_english_summary":"This AD requires owners/operators of Beechcraft Model E95 (Travelair) aircraft fitted with the Beech pneumatic de‑icer and B5 autopilot to carry out the work specified in Brittain Industries Service Bulletin No. 68‑1, Rev A, by 1 September 1971. Costs (parts, labour, downtime) fall to operators; maintenance organisations perform and certify the work.
