This AD requires operators of certain Fairchild SA227 aircraft with a modified nose‑wheel steering to add a Flight Manual amendment: perform a pre‑takeoff nose‑wheel steering check, keep the steering switch OFF for takeoff and landing, and only turn it ON after landing at taxi speed. (Requirement.)

It applies to listed models/serials; operators must obtain the amendment from a District Airworthiness Office and comply by 31 August 1993. Costs are administrative and operational (manual update, procedure, changed ground handling). Enforcement and discretion lie with the Civil Aviation Safety Authority. (Applicability; Compliance.)
