Airworthiness Directive 97-27353
one-timeAirworthiness Directives; Airbus Model A319, A320, and A321 Series Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A319, A320, and A321 series airplanes. This action requires revising the FAA-approved Airplane Flight Manual to increase monitoring of the flight path of the airplane to detect certain software anomalies of the flight management guidance system (FMGS), and take appropriate corrective actions. This amendment is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to ensure that the flightcrew detects and corrects an unintended flight path if certain software anomalies of the FMGS occur, which could result in an increased risk of collision with terrain or other airplanes.
Which aircraft AD 97-27353 applies to
Whether AD 97-27353 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.
