Airworthiness Directive · Amendment 39-18428 · Airbus Helicopters
Airbus Helicopters
This AD applies to Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters with an external life raft part number 245431-0, 245431-1, 245434-0, or 245434-1 installed, certificated in any category.
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters with certain external life rafts. This AD requires installing a sheath kit on the left-hand and right-hand raft deployment control systems. This AD is prompted by a report that the life raft deployment control could not be adjusted due to problems with the life raft deployment linkage. This unsafe condition, if not corrected, could result in failure of the external life raft to deploy and prevent evacuation of passengers during an emergency.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Before the next flight over water, install a sheath kit on each left-hand and right-hand life raft deployment control in accordance with the Accomplishment Instructions, paragraph 3.B.2, of Airbus Helicopters Alert Service Bulletin (ASB) No. AS365-25.01.45, Revision 1, dated February 2, 2015, or ASB No. EC155-25A128, Revision 1, dated February 2, 2015, whichever is applicable to your helicopter.
