You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Actions (g) Within 1,200 flight hours or 6 months after the effective date of this AD, whichever occurs first: Do a general visual inspection (GVI) to determine the RAT model, part number, and serial number, in accordance with Part 1 of the Accomplishment Instructions of EMBRAER Service Bulletin 170-24-0048, Revision 01, dated May 12, 2010; or EMBRAER Service Bulletin 190-24-0019, Revision 01, dated May 11, 2010; as applicable. A review of airplane maintenance records is acceptable in lieu of this inspection if the model, part number, and serial number of the RAT can be conclusively determined from that review. Note 1: For the purpose of this AD, a GVI is: “A visual examination of an interior or exterior area, installation or assembly to detect obvious damage, failure or irregularity. This level of inspection is made from within touching distance, unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight or drop-light, and may require removal or opening of access panels or doors. Stands, ladders or platforms may be required to gain proximity to the area being checked.” (1) For any RAT not having a serial number identified in EMBRAER Service Bulletin 170-24-0048, Revision 01, dated May 12, 2010; or EMBRAER Service Bulletin 190-24-0019, Revision 01, dated May 11, 2010: No further action is required by this paragraph.

A review of airplane maintenance records is acceptable in lieu of this inspection if the RAT identification plate can be conclusively determined to be marked with “24-5” from that review. (i) If the symbol “24-5” is marked on the RAT identification plate: No further action is required by this paragraph. (ii) If the symbol “24-5” is not marked on the RAT identification plate: Within 1,200 flight hours or 6 months after the effective date of this AD, whichever occurs first, replace the RAT balance screw(s) with a new balance screw(s), and mark the RAT identification plate with the symbol “24-5,” in accordance with Part 2 of the Accomplishment Instructions of EMBRAER Service Bulletin 170-24-0048, Revision 01, dated May 12, 2010; or EMBRAER Service Bulletin 190-24-0019, Revision 01, dated May 11, 2010; as applicable.

Credit for Actions Accomplished in Accordance With Previous Service Information (j) Actions accomplished before the effective date of this AD in accordance with EMBRAER Service Bulletins 170-24-0048 or 190-24-0019, both dated March 31, 2010, as applicable, are considered acceptable for compliance with the corresponding actions specified in this AD. FAA AD Differences Note 2: This AD differs from the MCAI and/or service information as follows: (1) The Brazilian ADs apply to “airplanes equipped with Hamilton Sundstrand ram air turbine (RAT), Model ERPS37T, Part Number (P/N) 1703781 Series; with the serial numbers (S/N) contained in Embraer Service Bulletin[s 170-24-0048 or 190-24-0019],” and their first action is an inspection to determine if affected equipment is installed. This AD applies to all of the airplanes, with the first action in the AD being an inspection to determine if affected equipment is installed, because the affected part could be rotated onto any of the airplanes listed in the applicability of this AD. (2) Although the MCAI states not to install the part identified in paragraph (h) of this AD after accomplishing the actions specified in paragraph (g)(2) of this AD, this AD prohibits installation of the part as of the effective date of this AD. Other FAA AD Provisions (k) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
