Embraer Jets Get Bolt and Washer Safety Mandate from FAA

## Summary

If you own or operate certain Embraer EMB-505 airplanes, this new FAA rule updates how you handle a tricky part called the clutch retaining bolt and washer on the aileron autopilot servo mount. Starting March 31, 2026, some planes need an extra initial fix, and there’s now an option to stop repeating the repairs. This keeps flights safer without breaking the bank or causing big delays.

## Abstract

The FAA is superseding Airworthiness Directive (AD) 2023-22- 11, which applied to certain Embraer S.A. (Embraer) Model EMB-505 airplanes. AD 2023-22-11 required repetitively replacing the clutch retaining bolt and washer of the aileron autopilot servo mount. Since the FAA issued AD 2023-22-11, the FAA has determined that the applicability should include certain Model EMB-505 airplanes and, for certain airplanes, an additional requirement is necessary for the initial replacement of the retaining bolt and washer. This AD incorporates these additional airplanes into the applicability, adds the additional requirement, and also provides an optional terminating action for the repetitive retaining bolt and washer replacement. The FAA is issuing this AD to address the unsafe condition on these products.

## Effects PRIA read

- Repetitive Bolt-and-Washer Replacements Required: cost, medium. If you own or operate an Embraer EMB-505 with serial numbers listed in this AD, you must follow repetitive replacements of the clutch retaining bolt and washer on the aileron autopilot servo mount beginning with this AD effective March 31, 2026. The FAA estimates a per-replacement cost of $135 (1 w…
- Optional Terminating Action Available: mixed, high. The AD provides an optional terminating action: replace the cable guard, clutch cartridge, bolt, and washer with new parts to stop the repetitive replacements. The FAA estimates the one-time cost per airplane for this terminating action at $810 (6 work-hours at $85/hr = $510 labor plus $300 parts).
- Which Airplanes Are Affected: cost, low. This AD applies to Embraer Model EMB-505 airplanes with serial numbers 50500004 through 50500012, 50500014, 50500016 through 50500665, and 50500667 through 50500779. The FAA states 773 airplanes worldwide meet the reduced applicability and 638 of those are on the U.S. registry.
- No Reporting Requirement in FAA AD: benefit, low. Although the ANAC service material suggests taking photos of removed parts and emailing them to manufacturers, this FAA AD does not require reporting or submission of removed-part information. You are not required by this AD to submit those pictures or reports.
- FAA Finds No Significant Economic Impact on Small Entities: benefit, low. The FAA certified that this AD will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act. The FAA also noted some costs may be covered under warranty by the manufacturer.
- Warranty May Cover Some Costs: benefit, low. The FAA states that according to the manufacturer, some of the costs of this AD may be covered under warranty, which could reduce out-of-pocket expenses for affected operators.
