Airworthiness Directive 2015-17-06
one-timeAirworthiness Directives; Airbus Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 series airplanes. This AD was prompted by reports that on airplanes equipped with sharklets, discretes (used to activate the load alleviation function) are connected on various flight computers using the same ground point. In these cases, the ground point segregation is no longer effective, and a single failure could lead to loss of sharklet identification by flight computers causing a return to the wing tip fence (no sharklet configuration) performance. This AD requires modification of the sharklet ground connection. We are issuing this AD to prevent loss of sharklet identification by the flight computers and subsequent reduced control of the airplane.
Which aircraft AD 2015-17-06 applies to
All manufacturer serial numbers on which Airbus mod 160500 or mod 160023 has been embodied in production, or modified in service via SB A320-57-1173, A320-57-1186, or A320-57-1187, except those on which Airbus mod 156108 has been embodied in production.
Whether AD 2015-17-06 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.
