Embraer Jets Face New Overheat Sensor Inspection Rules
Published Date: 5/22/2026
Rule
Summary
The FAA is requiring certain Embraer ERJ 190-100 ECJ airplanes to get a close check on their overheat detection sensors because some parts might not work right. If problems are found, those parts must be replaced, and no faulty parts can be installed anymore. This rule kicks in on June 26, 2026, helping keep flights safe without breaking the bank.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Mandatory ODS Sensor Inspections
If you operate Embraer ERJ 190-100 ECJ airplanes, you must perform a detailed inspection of certain overheat detection system (ODS) sensing elements and replace any defective parts. The AD is effective June 26, 2026, and the FAA estimates the inspection labor is 108 work-hours at $85 per hour = $9,180 per airplane, affecting 8 airplanes of U.S. registry (total estimated cost to U.S. operators $73,440).
On-Condition Actions Must Be Done Before Flight
If inspections find problems, the AD requires performing all applicable on-condition actions before further flight after each inspection. The FAA did not provide a definitive cost estimate for these on-condition actions.
Ban on Installing Affected Sensing Elements
The AD prohibits installing affected ODS sensing elements unless the part passed inspection and is indicated by a marking on one face of the connector hex nut. This change affects maintenance and parts procedures starting June 26, 2026.
