What to do

Operators of Embraer ERJ 190-300 and ERJ 190-400 aircraft must replace the drain tubes, increase drain hole apertures, install closing ribs, and fit shrouds and seals on both pylons as per the specified service bulletin. These modifications must be completed within 36 months from the effective date of July 23, 2026. Alternative methods of compliance may be approved by ANAC's Continuing Airworthiness Technical Branch if requested.

Summary

Brazilian Airworthiness Directive 2026-07-01 is issued by the Agência Nacional de Aviação Civil (ANAC) and applies to Embraer S.A. ERJ 190-300 and ERJ 190-400 aircraft as specified in Embraer Service Bulletin SB190E2-54-0009. This directive addresses a potential fire risk caused by hydraulic fluid leakage migrating to high-temperature areas in the pylon assembly. It mandates specific modifications to the drain tubes and installation of shrouds and seals on the pylons to mitigate this risk.

What changed

This new airworthiness directive introduces mandatory replacement of drain tubes, enlargement of drain hole apertures, installation of closing ribs in the pylon main boxes, and addition of shrouds and seals on both left-hand and right-hand pylons. These actions are detailed in Embraer Service Bulletin SB190E2-54-0009, Revision 00, dated January 9, 2026. The directive requires compliance within 36 months of its effective date.

Why it matters

This directive is critical for maintaining flight safety by preventing hydraulic fluid accumulation that could ignite and cause fire in the pylon area. Operators and maintenance organizations must ensure timely compliance to avoid operational restrictions and potential safety hazards. Compliance also ensures adherence to Brazilian aviation regulations and continued airworthiness of affected Embraer ERJ 190 aircraft.
