Airworthiness Directive · Amendment 39-14047 · Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Series Airplanes
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Series Airplanes
This AD applies to all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 series airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 series airplanes. This AD requires revising the Limitations section of the airplane flight manual to advise the flightcrew to make sure the correct instrument landing system (ILS) identifier is included on the flight management system (FMS) flight plan before the flightcrew initiates an approach to landing with the autopilot engaged. This AD is prompted by reports that the airplane's autopilot may apply large- amplitude control inputs while following ILS guidance to a runway that is not included on the FMS flight plan. We are issuing this AD to prevent hazardous maneuvers close to the ground, which could result in an impact with an obstacle or terrain.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 15 days after the effective date of this AD, revise the Limitations section of the EMBRAER Model ERJ 170 airplane flight manual (AFM) to include the following statement in the “Autopilot” subsection. This may be done by inserting a copy of this AD in the AFM.
“Before initiating an approach to landing with AUTOPILOT engaged, make sure the correct ILS identifier has been inserted on the FMS PROGRESS PAGE 1/3, Lines 5L and 5R.”
Note 1: When a statement identical to that in paragraph (f) of this AD has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed from the AFM.
