EASA SIB CE-12-18
Hawker Beechcraft 33, 35 and 36 Bonanza series Aeroplanes - Elevator Control Cable Condition
Summary
Special Airworthiness Information Bulletin SAIB: CE-12-18 is an FAA informational bulletin addressing the condition of the forward elevator control cable assembly on Hawker Beechcraft 33, 35, and 36 Bonanza series airplanes. It highlights the importance of inspecting the elevator control cables, especially where they route through closely spaced pulleys forward of the instrument panel. The bulletin also applies broadly to any airplane model with cable-driven flight controls.
What Changed
This bulletin introduces a reminder to owners and operators to adhere strictly to existing inspection procedures for flight control cables, emphasizing the risk of undetected wear or corrosion that could lead to cable failure. It does not impose new mandatory requirements or Airworthiness Directive actions but draws attention to recent field reports of cable failures in similar aircraft.
Why It Matters
Proper inspection of elevator control cables is critical to flight safety, as cable failure can compromise elevator control. Aviation professionals, including operators and maintenance organizations, must be vigilant to detect wear or corrosion early to prevent in-flight control issues. This bulletin helps reinforce best practices and awareness to maintain airworthiness and operational safety.
What To Do
Operators of Hawker Beechcraft 33, 35, and 36 Bonanza series airplanes should inspect the entire length of the flight control cables during each 100-hour or annual inspection. They should refer to Hawker Beechcraft Safety Communiqué No. 322 and FAA Advisory Circular AC 43.13-1B, Chapter 7, for detailed guidance. No specific compliance deadline is mandated, but adherence during routine inspections is recommended.
