This is a manufacturer-issued technical bulletin that tells mechanics exactly what to inspect, repair, or replace.\n\n**When it must be done:** Within **100 hours of flying time** after 29 October 1976.\n\n**Why it matters:** Faulty current limiters can cause electrical failures in flight — potentially affecting critical systems like radios, navigation, or lighting. This directive prevents that risk by mandating a specific safety fix.\n\n**Note:** This mirrors a US Federal Aviation Administration (FAA) directive (AD 76-13-05), showing Australia adopted the same safety standard as the aircraft's country of manufacture."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The directive text, as provided, sets a specific, self-contained scope: it applies only to listed Beechcraft B60 serial numbers and requires compliance with Beechcraft SI No. 0754-350 within a defined 100-hour window.
