EASA AD 18-139
WITHDRAWN - EXPLANATORY STATEMENT ATTACHED
Summary
EASA Withdrawal Statement for Proposed AD 18-139 announces the withdrawal of the proposed airworthiness directive concerning Airbus Helicopters BK117 D-2 and D-2m models equipped with Helionix Step 2 avionics. The withdrawal follows Airbus Helicopters' publication of Temporary Revision 3 to the Rotorcraft Flight Manual, which amended night operation procedures and restored an acceptable safety level. A modification application submitted by Airbus Helicopters is expected to provide a final fix for the identified unsafe condition.
What Changed
The Proposed AD 18-139 has been withdrawn due to the implementation of Temporary Revision 3 in the Rotorcraft Flight Manual for BK117 D-2 and D-2m helicopters, which addressed the safety concerns. Airbus Helicopters has also applied for approval of a modification expected to resolve the unsafe condition definitively. EASA may issue a new Proposed AD based on the assessment of this new modification.
Why It Matters
This withdrawal is important for operators and maintenance teams of Airbus Helicopters BK117 D-2 and D-2m models as it confirms that the temporary flight manual revisions have restored safety for night operations. It reduces immediate regulatory compliance burdens while signaling that a permanent fix is forthcoming. Compliance and safety management teams should monitor for future directives related to the new modification.
What To Do
Operators of affected BK117 D-2 and D-2m helicopters should ensure that Temporary Revision 3 of the Rotorcraft Flight Manual is inserted and followed for night operations. They should also stay informed about the approval and implementation of the forthcoming modification that aims to permanently resolve the unsafe condition. No immediate compliance deadline is specified in this withdrawal statement.
