| AD/ERJ-190/1 | Air Data Smart Probes | 5/2008 DM |
|---|
| Applicability: | ERJ-190 model aeroplanes, equipped with Air Data Smart Probes part number (P/N) 2015G2H2H-4( ), 2015G2H2H-5( ), 2015G2H2H-6( ) or 2015G2H2H-7( ). |

| Requirement: | 1. Carry out a detailed inspection of the four "Air Data Smart Probes" drain hole and remove the accumulated moisture in accordance with Embraer Service Bulletin 190-34-0003, original issue, dated 2 December 2005 or further revisions approved by the Brazilian Agência Nacional de Aviação Civil (ANAC). |
| Note 1: For the purpose of this Directive, a detailed inspection is defined as: "An intensive examination of a specific item, installation or assembly to detect damage, failure or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirrors, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate access procedures may be required." | |
| The optional installation of Air Data Smart Probes P/N 2015G2H2H-8( ) in accordance with the procedures detailed in the Embraer SB 190-34-0008 original issue, dated 19 September 2006 or further revisions approved by ANAC, constitutes terminal action to the repetitive inspections. | |

| Note 2: ANAC AD 2006-05-08R1 refers. | |
| Compliance: | For Requirement 1 - Either within the next 600 hours time in service (TIS) after the first issue of an Australian Certificate of Airworthiness and thereafter, at intervals that do not exceed 600 hours TIS until the Air Data Smart Probe is replaced by a probe P/N 2015G2H2H-8( ). |
| For Requirement 2 - As of the effective date of this Directive. | |
| This Airworthiness Directive becomes effective on 27 March 2008. |
| Background: | The ANAC has received reports of moisture being found in the pneumatic passage between the pitot port and the pressure sensors in the Air Data Smart Probe. That moisture may freeze and block the sensors, causing erroneous information to the Air Data System. |
