Airworthiness Directive 2013-17-01
one-timeAirworthiness Directives; Eurocopter France Helicopters
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Eurocopter France (Eurocopter) Model AS350 and AS355 helicopters. This AD requires inspecting the tail rotor control stop screws to determine if they are correctly aligned and adjusting the screws if they are misaligned. This AD is prompted by the discovery of a loose nut on the tail rotor control stop and a misaligned tail rotor control stop screw. The actions of this AD are intended to detect a loose nut or a misaligned stop screw, which, if not corrected, could limit yaw authority, and consequently, result in a loss of helicopter control.
Which aircraft AD 2013-17-01 applies to
AS350B/BA/B1/B2/C/D/D1 and AS355E/F/F1/F2: applies with an autopilot installed. AS350B3: applies with an autopilot or modification 073252 installed. AS355N/NP: applies with an autopilot or modification 071908 installed.
Whether AD 2013-17-01 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
