EASA SIB CE-15-10: Eaton (Aeroquip) 800 series Fuel, Oil, or Hydraulic Fluid Hoses

What to do

Operators should inspect aircraft for installation of Eaton 800 series hoses with part numbers AE866, AE846, or AE818 produced from July 2009 to September 2014 in fire-resistant or fireproof hose locations. If found, the FAA recommends replacing or modifying these hoses using FAA-approved service instructions, which may include adding insulating sleeves or replacing with compliant hoses. Stakeholders should contact Eaton or type design holders for specific service bulletins and technical guidance.

Summary

The FAA Special Airworthiness Information Bulletin SAIB: CE-15-10 addresses an airworthiness concern involving Eaton (Aeroquip) 800 series fuel, oil, or hydraulic fluid hoses, specifically part numbers AE866, AE846, and AE818 produced between July 2009 and September 2014. These hoses may not meet required fire-resistant or fireproof standards in installations where such protection is necessary. The bulletin applies to aircraft using these hoses in fire-critical areas and provides guidance on the issue.

What changed

This bulletin introduces information about a potential fire resistance shortfall in certain Eaton 800 series hoses due to a manufacturing change starting in July 2009. It does not mandate corrective action but informs operators that the issue is under review for possible future airworthiness directives. The bulletin recommends replacing or modifying affected hoses to meet fireproof or fire-resistant standards.

Why it matters

This matters because hoses that fail to meet fire resistance requirements could allow flammable fluids to spray onto existing fires, posing a significant safety risk. Operators, maintenance organizations, and compliance teams need to be aware of this potential hazard to ensure aircraft safety and regulatory compliance. Proactively addressing the issue can prevent future operational disruptions and enhance fire safety in critical systems.
