AD/DO 328/65 - Power Plant Air Intake

This Airworthiness Directive orders operators of specified Dornier 328-100 aeroplanes to replace the power-plant air intake, fit a by‑pass duct outlet cover and carry out repeated visual/tactile inspections according to two named Dornier service bulletins. It applies to aircraft with serial numbers listed in those service bulletins; the replacement must be done within 30 days and inspections no less often than every 7 days (inspections may be unnecessary if alternative service bulletins are incorporated).
