What to do
Operators of ATR42 and ATR72 aircraft should review and implement the actions recommended by ATR in the referenced operator messages and service bulletins. They should update flight crew training and manuals as per the temporary revisions provided by ATR. No mandatory compliance deadline is specified, but timely adoption of these recommendations is advised to enhance flight safety.
Summary
EASA Safety Information Bulletin 2016-20R1 is an airworthiness bulletin addressing flight control issues on ATR42 and ATR72 aircraft. It focuses on Crew Resource Management to avoid dual and opposite flight control inputs that can cause structural damage, especially involving the pitch uncoupling mechanism and elevator controls. The bulletin provides updated operational guidance and references ATR service bulletins and operator messages for affected aircraft.
What changed
This revision updates the original EASA SIB 2016-20 by incorporating new ATR operator messages and service bulletins issued between 2016 and early 2017. It includes advanced temporary revisions to the Aircraft Flight Manual and Flight Crew Operating Manual to mitigate risks from rapid alternating and dual opposite control inputs. The document clarifies that the safety concern does not currently require mandatory Airworthiness Directive action.
Why it matters
The bulletin is important for operators and maintenance organizations of ATR42 and ATR72 aircraft because improper flight control inputs can lead to structural failures, including damage to the horizontal stabilizer. Understanding and implementing the recommended Crew Resource Management practices helps prevent in-flight pitch disconnect events and potential costly repairs or safety incidents. Compliance teams benefit from awareness of the latest operational and inspection instructions to maintain airworthiness.
