Keep A321 Floors Firm: FAA Tweaks Inspection Rules

Published Date: 8/27/2025

Rule

Summary

The FAA is updating safety rules for certain Airbus A321 airplanes to keep them safe from cracks in the cabin floor beams. They’re changing when inspections need to happen based on flight hours and adding an option to fix the problem early. Airlines flying these planes should act soon to avoid costly repairs and keep passengers safe.

Analyzed Economic Effects

3 provisions identified: 0 benefits, 2 costs, 1 mixed.

Inspections and Repairs Still Required

If you operate Airbus Model A321-111, -112, -131, -211, -212, -213, -231, or -232 airplanes, the FAA continues to require repetitive inspections for cracking in the cabin floor beam junction at certain fuselage frame locations and repairs when cracks are found, as required by AD 2017-14-14. Operators must keep performing those inspections and repairs to address the unsafe condition.

Optional Early Modification Added

The AD adds an option for operators to perform an optional modification that addresses the cabin floor beam cracking issue earlier than waiting for repetitive inspections. The modification is discretionary but is included as an alternative compliance path in this AD.

Inspections Now Tied to Flight Hours

The FAA revised the AD so required inspection compliance times are based on flight hours in addition to prior criteria. Operators must schedule inspections according to the new flight-hour–based compliance times for the same A321 models covered by AD 2017-14-14.
