Airworthiness Directive 2016-06-13
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 investigations that revealed that the cover seal of the brake dual distribution valve (BDDV) was damaged and did not ensure efficient sealing. This AD requires modifying the BDDVs having certain part numbers; modifying the drain hose of the BDDV; checking for the presence of water, ice, and hydraulic fluid; re-identifying the BDDV; and doing related investigative and corrective actions if necessary. We are issuing this AD to prevent damage to the BDDV, which could lead to water ingestion in the BDDV and freezing of the BDDV in flight, possibly resulting in loss of braking system function after landing.
Which aircraft AD 2016-06-13 applies to
Applies to all manufacturer serial numbers except those on which Airbus Modification 26925 has been embodied in production.
Whether AD 2016-06-13 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.
