What to do
Owners and operators should inspect the rudder horn for corrosion and paint deterioration as outlined in Textron Aviation Mandatory Service Letter SEL-27-02R1. Any rudder horn showing light to severe corrosion must be repaired or replaced, and reassembled using corrosion-resistant sealants and compounds. Findings of corrosion or damage should be reported via email to the FAA at ccb-cos@faa.gov. No specific compliance deadline is stated in the bulletin.
Summary
Special Airworthiness Information Bulletin SAIB: 2025-11 is an FAA informational bulletin addressing an airworthiness concern related to the rudder control system on Textron Aviation Inc. (formerly Cessna Aircraft Company) Model 150 series, A150 series, F150 series, FA150 series, 152 series, A152, F152, and FA152 airplanes. The bulletin also notes that similar DINFIA Model A-150 airplanes manufactured in Argentina are affected. It informs owners and operators about inspection, repair, and treatment recommendations for airplanes equipped with rudder stop modification service kits SK152-24B and SK152-25B or their previous versions.
What changed
The bulletin introduces updated corrosion protection procedures and revised service kits SK152-24C and SK152-25C, replacing earlier versions. It references Textron Aviation service documents SEB01-1R2 and SEL-27-02R1, which specify inspection, repair, or replacement of rudder horns affected by dissimilar metal corrosion. Additionally, it highlights the FAA's approval of a Global Alternative Method of Compliance (AMOC) for meeting AD 2009-10-09 R2 requirements using these updated service kits and procedures.
Why it matters
This bulletin is important for aviation professionals because it addresses a known safety risk of rudder horn failure due to corrosion, which can lead to loss of rudder control. Operators and maintenance organizations must be aware of the corrosion risks associated with certain rudder stop kits and take appropriate action to ensure continued safe operation. Compliance with the recommended inspections and repairs helps prevent potential in-flight control issues and supports regulatory compliance with existing airworthiness directives.
