ACTION: Final rule; request for comments. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 170-100 STD, -100 LR, -100 SU, and -100 SE; ERJ 170-200 STD, -200 LR, -200 SU; ERJ 190-100 STD, -100 LR, -100 IGW, and -100 ECJ; and ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by a report of the failure of the inner pane of certain passenger windows to meet maximum operating pressure and lack of fail-safe design. This AD requires determining if certain NORDAM passenger windows are installed, and performing corrective actions if any affected part is installed. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective April 26, 2022. The FAA must receive comments on this AD by May 26, 2022. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow the instructions for submitting comments. • Fax: 202-493-2251. • Mail: U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590. • Hand Delivery: Deliver to Mail address above between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

SUPPLEMENTARY INFORMATION: Background The FAA received a voluntary self-disclosure report indicating possible failure of the inner pane of certain passenger windows to meet fail-safe loads in the event of the complete failure of the outer pane. Manufacturer testing was performed to confirm the inadequacy of the inner window pane design. The results of the testing revealed that the inner pane of the passenger window failed to meet maximum operating pressure. The root cause was determined to be an inner window pane dimensional thickness that is inadequate to support cabin pressurization loads. As a result, the design was found to not be fail safe, meaning that the window assembly does not retain the required residual strength to maintain safe flight and landing of the a…
