Airworthiness Directive · Amendment 39-11976 · Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145 Series Airplanes
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145 Series Airplanes
Model EMB-145 series airplanes; serial numbers 145010, 145011, and 145013 through 145016 inclusive; certificated in any category.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-145 series airplanes, that requires replacement of defective hydraulic tubing in the left and right wings with new hydraulic tubing. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent the loss of hydraulic pressure which could result in reduced controllability of the airplane.
To prevent the loss of hydraulic pressure due to failed hydraulic tubing and the consequent reduced controllability of the airplane, accomplish the following:
(a) Within 800 flight hours after the effective date of this AD, replace hydraulic tubing in the left and right wings with new tubing, in accordance with EMBRAER Service Bulletin 145-29-0003, dated November 13, 1997.
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.
