EASA AD BR-2024-07-01
Kidde Aerospace & Defense - Overheat Detection System Sensing Elements - Inspection
Summary
Brazilian Airworthiness Directive AD No. 2024-07-01 issued by ANAC mandates inspection and possible replacement of Kidde Aerospace & Defense Overheat Detection System sensing elements on Embraer ERJ 190-100 ECJ aircraft as identified in Embraer Service Bulletin 190LIN-36-0013 revision 03. The directive addresses defective sensing elements produced before January 31, 2021, which may fail to detect thermal bleed leaks and pose fire risks. It applies to all affected aircraft registered in Brazil.
What Changed
This new directive introduces mandatory inspections and replacements of specific ODS sensing elements on various bleed line areas of the Embraer ERJ 190-100 ECJ to address a manufacturing quality escape. It requires detailed inspections, troubleshooting, and prohibits installation of affected parts unless airworthy. The directive also provides credit for previous compliance with earlier service bulletin revisions.
Why It Matters
This AD is critical for maintaining flight safety by preventing latent failures in overheat detection that could lead to ignition sources in fuel tanks and structural damage. Operators and maintenance teams must ensure affected sensors are inspected and replaced as necessary to avoid potential fire hazards and comply with Brazilian aviation regulations. Timely compliance helps avoid operational disruptions and ensures continued airworthiness.
What To Do
Operators must inspect the ODS sensing elements on specified airplane bleed line areas within 7,500 flight hours or 36 months from July 31, 2024, whichever occurs first. If defects or discrepancies are found, sensors must be replaced following the procedures in Embraer Service Bulletin 190LIN-36-0013 revision 03. Installation of affected parts is prohibited unless verified as airworthy, and all actions must be recorded in maintenance logs.
