Airworthiness Directive · Amendment 39-19549 · Flight controls
Pacific Aerospace Ltd. Airplanes
This AD applies to all Pacific Aerospace Ltd. Model FBA-2C1, FBA-2C2, FBA-2C3, and FBA-2C4 airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all Pacific Aerospace Ltd. Model FBA-2C1, FBA-2C2, FBA-2C3, and FBA-2C4 airplanes. This AD was prompted by a report of corrosion found in the external and internal surfaces of an elevator push-pull rod. This AD requires an inspection for corrosion of the elevator push-pull rod assembly, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Within 50 hours' time-in-service or 60 days after the effective date of this AD, whichever occurs first, do a borescopic inspection for corrosion of the interior of the elevator push-pull rod assembly, and before further flight replace any elevator push-pull rod assembly that has internal corrosion, in accordance with the Accomplishment Instructions of Pacific Aerospace Ltd. Service Bulletin PACSB/2C/001, Issue 1, dated September 25, 2018. If no internal corrosion is found, before further flight inspect for corrosion of the exterior of the elevator push-pull rod assembly and do all applicable corrective actions for reassembly, in accordance with the Accomplishment Instructions of Pacific Aerospace Ltd. Service Bulletin PACSB/2C/001, Issue 1, dated September 25, 2018. Do all other specified actions as applicable before further flight in accordance with the Accomplishment Instructions of Pacific Aerospace Ltd. Service Bulletin PACSB/2C/001, Issue 1, dated September 25, 2018.
