Airworthiness Directive · Amendment 39-14902 · Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Airplanes
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Airplanes
This AD applies to EMBRAER Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes, certificated in any category; serial numbers 17000007, 17000033, 17000034, 17000036 through 17000046 inclusive, and 17000050 through 17000067 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170 airplanes. This AD requires replacement of certain electrical bonding clamps and attaching hardware with new or serviceable parts, as applicable, and other specified action. This AD results from failure of an electrical bonding clamp, used to attach the electrical bonding straps to the fuel system lines. We are issuing this AD to prevent loss of bonding protection in the interior of the fuel tanks or adjacent areas that, in combination with lightning strike, could result in a fuel tank explosion and consequent loss of the airplane.
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 6,600 flight hours after the effective date of this AD: Replace all electrical bonding clamps having part number AN735D4 or AN735D6 with new clamps and replace the attaching hardware with new or serviceable attaching hardware, and do the other specified action, by accomplishing all of the actions specified in the Accomplishment Instructions of EMBRAER Service Bulletin 170-28-0009, Revision 01, dated February 23, 2006. The other specified action must be done before further flight.
Actions done before the effective date of this AD in accordance with EMBRAER Service Bulletin 170-28-0009, dated December 30, 2005, are acceptable for compliance with the requirements of paragraph (f) of this AD.
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.
