EASA AD US-2026-18-08
Fuselage - Cargo Track Crown Fitting - Inspection
Summary
Fuselage - Cargo Track Crown Fitting - Inspection is a Federal Aviation Administration (FAA) Airworthiness Directive (AD 2026-18-08) addressing certain Boeing 767-300F series airplanes. This directive requires inspection and possible replacement of titanium cargo track crown fittings due to suspect material certifications. The AD aims to prevent cargo track failure that could compromise airplane controllability and damage critical systems in the main cargo compartment.
What Changed
This new AD introduces a mandatory X-ray fluorescence (XRF) spectrometer inspection to verify the material composition of the cargo track crown fittings or requires replacement of all such fittings with new ones made from Ti-6Al-4V alloy. It clarifies that installation of Supplemental Type Certificate STC ST01920SE does not affect compliance. The directive also includes on-condition actions based on inspection results.
Why It Matters
This AD is critical for operators and maintenance organizations because suspect titanium fittings could fail, leading to uncommanded cargo pallet movement and damage to structural and system components. Compliance ensures the structural integrity of cargo tracks and maintains safe aircraft controllability. It also addresses supply chain material certification issues that could otherwise go undetected.
What To Do
Operators of Boeing 767-300F series airplanes must perform the XRF spectrometer inspection or replace all cargo track crown fittings with new Ti-6Al-4V alloy fittings by October 22, 2026. They should follow Boeing Alert Requirements Bulletin 767-53A0337 RB dated October 17, 2025, for detailed procedures. No alternative method of compliance is needed for airplanes with STC ST01920SE installed.
