ATR72 Operators Must Adopt Stricter Maintenance Checks

Published Date: 5/27/2026

Rule

Summary

The FAA is updating safety rules for certain ATR72 airplanes to keep them flying safely. Owners and operators must update their maintenance plans with new, stricter checks starting July 1, 2026. This helps prevent problems but might mean some extra work and costs to follow the new rules.

Analyzed Economic Effects

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

Operators Must Revise Maintenance Programs

If you operate certain ATR72 airplanes, you must revise your maintenance or inspection program to include the new, more restrictive airworthiness limitations in EASA AD 2025-0046. This AD is effective July 1, 2026 and applies to ATR72-101, -102, -201, -202, -211, -212, and -212A airplanes with original airworthiness or export certificates issued on or before November 22, 2024.

FAA Estimates Cost Per Operator ($7,650)

The FAA estimates this AD affects 32 U.S.-registered ATR72 airplanes and 6 domestic entities (5 of which are small entities). The agency estimates an average total cost per operator of $7,650 (90 work-hours × $85 per hour), which it calculates as 0.189% of the average small entity's annual revenue.

Rule Aims to Prevent Fuel Tank Ignition

The AD is issued to address the potential for ignition sources inside fuel tanks that could cause a fuel tank explosion and loss of the airplane. By requiring the new airworthiness limitations, the FAA aims to reduce the risk of such catastrophic failures for the affected ATR72 airplanes.

Accelerated 90-Day Compliance Deadline

The AD requires operators to revise their existing maintenance or inspection program within 90 days after the effective date (effective date July 1, 2026), rather than the 12-month window in the corresponding EASA AD. The initial compliance times for the tasks are at the applicable limitations or within 90 days after the effective date, whichever occurs later.
