EASA AD 2016-0247-CN
CANCELLED: Engine Fuel & Control — P30 Sense Line Air Tube — Drainage / Inspection
Summary
EASA Airworthiness Directive 2016-0247-CN is a cancellation notice for the previously issued Emergency AD 2016-0247-E concerning Rolls-Royce Trent XWB engines installed on Airbus A350 aircraft. The directive addresses the drainage and inspection of the P30 sense line air tube related to engine fuel and control systems. This cancellation confirms that the unsafe condition previously identified no longer exists due to corrective software updates.
What Changed
EASA Airworthiness Directive 2016-0247-CN cancels the Emergency AD 2016-0247-E, which required a one-time inspection and drainage of the P30 sense line air tubes. The cancellation follows the embodiment of a Rolls-Royce software update that corrects the Engine Electronic Control failure related to static P30 signals, eliminating the risk of reduced thrust control caused by water accumulation.
Why It Matters
This cancellation is important for aviation professionals because it confirms that the previously identified safety risk related to the P30 sense line air tube in Trent XWB engines has been mitigated through software updates. Operators and maintenance organizations can be assured that no further inspections or drainage actions are required, reducing operational disruptions and maintenance workload.
What To Do
Affected operators and maintenance teams do not need to perform any further inspections or drainage related to the P30 sense line air tube as required by the cancelled AD. They should ensure that the Rolls-Royce software update correcting the Engine Electronic Control is embodied on all Trent XWB engines. For technical questions, stakeholders should contact Rolls-Royce representatives or EASA Safety Information Section.
