FAA Orders X-Rays for Boeing Cargo Track Flaws

Published Date: 2/17/2026

Proposed Rule

Summary

The FAA wants to make sure certain Boeing 767-300F airplanes are super safe by checking or replacing some cargo track parts that might be made from the wrong materials. Airlines will need to inspect these parts with special X-ray tools or swap them out, helping prevent any safety issues. Comments on this plan are open until April 3, 2026, so affected operators should act soon to avoid delays or extra costs.

Analyzed Economic Effects

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

Mandatory XRF Inspection or Replacement

The FAA proposes a new airworthiness directive for Boeing 767-300F series airplanes (per Boeing Alert Requirements Bulletin dated October 17, 2025) that would require an X-ray fluorescence (XRF) spectrometer inspection to identify the material of cargo track crown fittings or replacement of all cargo track crown fittings with new fittings made of Ti-6Al-4V alloy. This proposed AD applies to affected airplanes identified in the Boeing bulletin and is intended to address suspect material certifications that could cause cargo track failure.

Estimated Compliance Cost Numbers

The FAA estimates the AD would affect 43 U.S.-registered airplanes. Estimated costs: replacing all cargo track crown fittings is 156 work-hours × $85 = $13,260 labor plus $63,540 parts = $76,800 per airplane (up to $3,302,400 total for U.S. registry). An XRF spectrometer inspection is estimated at 92 work-hours × $85 = $7,820 per airplane (up to $336,260 total for U.S. registry).

Unsafe Condition: Cargo Track Failure Hazard

The FAA found suspect material certifications for some titanium cargo track crown fittings; if not addressed this could result in cargo track failure, uncommanded movement of a cargo pallet, damage to critical systems in the main cargo compartment sidewall or ceiling, and inability of a principal structural element to sustain limit loads, which could significantly affect airplane controllability. The proposed AD is intended to prevent that unsafe condition.

Manufacturer Warranty May Reduce Costs

The manufacturer states that some or all of the costs of this proposed AD may be covered under warranty, which could reduce the cost impact on affected operators. The FAA notes this possibility in its cost discussion.

FAA Finding on Small Entity Economic Impact

The FAA determined that this proposed AD would not have a significant economic impact, positive or negative, on a substantial number of small entities under the Regulatory Flexibility Act. This is the agency's regulatory finding included in the proposed rule.
