The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes; Model ERJ 190-100 STD, - 100 LR, -100 ECJ, and -100 IGW airplanes; and Model ERJ 190-200 STD, - 200 LR, and -200 IGW airplanes. This AD was prompted by reports of the ram air turbine (RAT) compartment door seal peeling off and tangling up on the RAT rotor during flight test. This AD requires a general visual inspection for peeling-off of the RAT compartment door seal, bonding if necessary, and the rework of the RAT compartment door seal attachment. The FAA is issuing this AD to address the unsafe condition on these products.
(1) For airplanes identified in paragraph (c)(1) of this AD: Within 750 flight hours after the effective date of this AD, do a general visual inspection of the RAT compartment door seal for peeling-off conditions (disbonding), do all applicable bonding, and rework the RAT compartment door seal attachment, in accordance with the Accomplishment Instructions of the service information identified in paragraph (c)(1) of this AD. Do all applicable bonding before further flight.
(2) For airplanes identified in paragraph (c)(2) of this AD: Within 750 flight hours after the effective date of this AD, do a general visual inspection of the RAT compartment door seal for peeling-off conditions (disbonding), do all applicable bonding, and rework the RAT compartment door seal attachment, in accordance with the Accomplishment Instructions of the service information identified in paragraph (c)(2) of this AD. Do all applicable bonding before further flight.
(3) For airplanes identified in paragraph (c)(3) of this AD: Within 400 flight hours or 6 months after the effective date of this AD, whichever occurs first, do a general visual inspection of the RAT compartment door seal for peeling-off conditions (disbonding), do all applicable bonding, and rework the RAT compartment door seal attachment, in accordance with the Accomplishment Instructions of the service information identified in paragraph (c)(3) of this AD. Do all applicable bonding before further flight.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
