- Published
AI-generated summary of the official EASA document. Verify against the PDF before acting.
What to do
Operators and maintenance personnel should follow the existing Model 336 and 337 maintenance manual inspection intervals, including visual inspections every 100 hours or 12 months and expanded inspections every 600 and 800 hours or 12 months and 4 years respectively. Special attention should be given to the cable area near the bellcrank, possibly requiring cable removal for thorough inspection. Reviewing AC 43.13-1B, Chapter 7, paragraph 7-149 on cable system inspection is also recommended.
Summary
The Special Airworthiness Information Bulletin SAIB: CE-12-24R1 is an FAA advisory regarding frayed flap extend cables on Cessna Models F337, 336, and 337 airplanes, including those formerly produced by Reims. It informs owners, operators, and maintenance personnel about the potential for cable wear and recommends inspection practices to ensure continued airworthiness. This bulletin is informational and does not mandate regulatory action under 14 CFR part 39.
What changed
This revision of SAIB CE-12-24 specifically includes the Model F337 in the advisory, clarifying its applicability rather than relying on the general term 'all derivatives.' It updates inspection recommendations based on recent reports of cable fraying and emphasizes the critical inspection areas around the bellcrank where wear commonly occurs.
Why it matters
Frayed flap extend cables can compromise flight control reliability, posing a safety risk if undetected. Aviation professionals, including operators and maintenance organizations, need to be aware of the inspection challenges due to cable positioning and the potential for hidden damage. Proper inspection intervals and techniques help prevent unexpected cable failures and maintain regulatory compliance.
