Airworthiness Directive · Amendment 39-19390 · Lights
Airbus Helicopters
This AD applies to Airbus Helicopters Model AS-365N2 and AS 365 N3 helicopters, certificated in any category, with a lower strobe light installed.
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS-365N2 and AS 365 N3 helicopters with a lower strobe light installed. This AD requires installing a cable mount, inspecting the lower strobe light wiring harness, and re-routing the wiring harness. This AD was prompted by reports of interference between the lower strobe light wiring harness and the helicopter structure. The actions of this AD are intended to prevent an unsafe condition on these helicopters.
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.
Within 50 hours time-in-service:
(1) Install cable mount part number (P/N) ASMS-A to the helicopter structure as depicted in Figure 1, Detail A and Detail C, of Airbus Helicopters Alert Service Bulletin No. AS365-05.00.73, Revision 1, dated December 12, 2016 (ASB AS365-05.00.73).
(2) Inspect the lower strobe light harness and the harness between the cut-off connector and Frame 2000 for tears in the spiral tape and for chafing of the harness wires. If there is a tear in the spiral tape, before further flight, replace the spiral tape. If there is any chafing, before further flight, replace the chafed harness.
(3) Route the lower strobe light harness and the harness between the cut-off connector and Frame 2000 and secure as depicted in Figure 1, Detail A and Section B-B, of ASB AS365-05.00.73.
Note 1 to paragraph (e) of this AD: Airbus Helicopters identifies the actions in ASB AS365-05.00.73 as Modification 365P084778.00.
