Elevator Push-pull Cable — Potential of Loss of Connection
Summary
EASA Safety Information Bulletin 2023-12 is an airworthiness bulletin addressing a potential loss of connection in the elevator push-pull cable on Flight Design CTLS-ELA aeroplanes. The bulletin highlights a reported case of a missing nut on the forward bell crank connection, which could lead to detachment of the stabilizer control cable. The issue affects all serial numbers of Flight Design CTLS-ELA aircraft, including those operating under permanent Flight Conditions.
What Changed
This bulletin introduces a precautionary inspection requirement following a reported occurrence of a missing nut on the elevator push-pull cable connection. It references Flight Design Safety Alert SA-ELA-CTLS-01, which provides detailed inspection and reporting instructions. No Airworthiness Directive action is mandated at this time under Regulation (EU) 748/2012.
Why It Matters
This information is important for operators and maintenance organizations to prevent potential control system failures due to cable detachment. Early detection through inspection can mitigate risks associated with improper maintenance or possible production issues. Compliance teams need to be aware that while this is not an unsafe condition warranting an AD, vigilance and reporting are recommended.
What To Do
Operators of Flight Design CTLS-ELA aeroplanes should perform inspections of the elevator push-pull cable connection as instructed in Flight Design Safety Alert SA-ELA-CTLS-01. Any findings should be reported to Flight Design. There is no mandatory compliance deadline, but prompt action is advised to ensure continued airworthiness.
