FAA Targets Rusty Rudders on Vintage German Flyers

Published Date: 9/15/2026

Proposed Rule

Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Defence and Space GmbH Model BO-209-150 FF, BO-209-150 FV, BO-209-150 RV, BO-209-160 FV, BO-209-160 RV, and B[ouml]lkow Jr. airplanes. This proposed AD was prompted by reports of corrosion damage on the rudder drive. This proposed AD would require repetitive inspections of the rudder drive, corrective actions including replacement if corrosion is detected and the application of a corrosion inhibitor. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.

Analyzed Economic Effects

3 provisions identified: 0 benefits, 3 costs, 0 mixed.

Mandatory rudder inspections every 5 years

If you operate one of the listed Airbus Defence and Space or Bölkow Jr. airplane models, you must remove the rudder and inspect the rudder drive within 2 months after the AD’s effective date and then at intervals not to exceed 5 years. The FAA estimates each inspection will take 2 work-hours (2 x $85 = $170) per airplane and, for U.S. operators, the total estimated cost for the five affected U.S.-registered airplanes is $850.

Replacement required if corrosion found

If any corrosion is found during an inspection, you must replace the rudder drive before further flight with a serviceable part. The FAA’s on-condition cost entries list replacement as 15 work-hours at $85 per hour and parts costing $2,275 (values shown in the FAA’s cost tables).

Corrosion inhibitor and parts installation ban

After each inspection or replacement you must apply a corrosion inhibitor to the inside of the rudder drive before further flight. As of the AD’s effective date, you may not install an affected rudder drive part on any airplane unless it is a serviceable part (defined as a new part or a part with less than 5 years since the last inspection with no corrosion found and corrosion inhibitor applied per the referenced Airbus service bulletin). The FAA estimates applying the inhibitor takes 1 work-hour (1 x $85 = $85) plus $50 in parts, for a per-airplane cost of $135 and $675 for the five U.S. airplanes.
