What to do
Affected operators and maintenance providers should note that no action is required following EASA Airworthiness Directive 2017-0198-CN. They should update their compliance documentation to reflect the cancellation and discontinue any planned replacements mandated by the original AD 2017-0198. For technical questions, stakeholders can contact Rolls-Royce Deutschland or EASA as provided.
Summary
EASA Airworthiness Directive 2017-0198-CN is a cancellation notice for the previous directive concerning the replacement of the Engine Electronic Controller (EEC) firebox assembly on Rolls-Royce Deutschland BR700-710 series engines. This directive affects BR700-710A2-20 and BR700-710C4-11 engines installed on aircraft such as the Gulfstream GV-SP (G500, G550) and Bombardier BD-700 series. The cancellation reflects updated findings that the previously mandated replacement is no longer necessary.
What changed
EASA Airworthiness Directive 2017-0198-CN cancels the earlier AD 2017-0198, which required replacement of affected EEC firebox assembly parts due to deterioration of the intumescent paint system. New test results showed that even with significant paint damage, no unsafe condition exists, removing the need for mandatory replacement. Consequently, no further action or compliance is required under this cancellation notice.
Why it matters
This cancellation relieves operators and maintenance organizations from the burden of replacing EEC firebox assembly parts on affected Rolls-Royce BR700-710 engines, reducing maintenance costs and downtime. It clarifies compliance requirements and ensures that resources are focused on genuine safety concerns. Compliance teams can update their records to reflect that the previous directive is no longer applicable.
