Airworthiness Directive · Amendment 39-15550 · Ice and rain protection
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ and EMB-145XR Airplanes
This AD applies to EMBRAER Model EMB-135BJ and EMB-145XR airplanes, certificated in any category, as identified in EMBRAER Service Bulletins 145-30-0048 and 145LEG-30-0015, both dated March 31, 2006.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
At the applicable compliance time specified in paragraph (f)(1) or (f)(2) of this AD, unless already done, remove the sealant used to protect the LH and RH clear ice detector wiring conduits at the holes through the wing spars and install protective Teflon spiral, in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 145-30-0048 or 145LEG-30-0015, both dated March 31, 2006, as applicable.
(1) For Model EMB-135BJ airplanes: Within 4,000 flight hours or 48 months after the effective date of this AD, whichever occurs first.
(2) For Model EMB-145XR airplanes: Within 5,000 flight hours or 48 months after the effective date of this AD, whichever occurs first.
Note: This AD differs from the MCAI and/or service information as follows. The MCAI specifies a compliance time of “5,000 flight hours” for all affected airplanes. This AD requires a compliance time of “5,000 flight hours” for Model EMB-145XR airplanes, and “4,000 flight hours” for Model EMB-135BJ airplanes. This difference has been coordinated with the Agência Nacional de Aviação Civil.
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.
