Airworthiness Directive 2013-16-09
recurringAirworthiness Directives; Airbus Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD requires an inspection to determine airplane configuration and part numbers of the landing gear control interface unit and main landing gear (MLG) door actuators; and, for affected airplanes, repetitive inspections of the opening sequence of the MLG door actuator, and replacement of the MLG door actuator if necessary. This AD also provides optional terminating action for the repetitive inspections. This AD was prompted by a report of a MLG failing to extend during landing, and a determination that a certain configuration of landing gear control interface unit and actuators may result in masking of centralized fault display system messages that are necessary to mitigate risks associated with failure of MLG extension or down-locking. We are issuing this AD to detect and correct such a configuration, which could prevent the full extension or down-locking of the MLG, possibly resulting in MLG collapse during landing and consequent damage to the airplane and injury to occupants.
Which aircraft AD 2013-16-09 applies to
Whether AD 2013-16-09 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.
