## BRAZILIAN AIRWORTHINESS DIRECTIVE

**AD No.: 2011**  **- 02**  **- 01**  **Effective Date: 1**  **2 Feb** 

**. 2011**  The following Brazilian Airworthiness Directive (AD), issued by the Agência Nacional de Aviação Civil (ANAC) in accordance with provisions of Chapter IV, Title III of Código Brasileiro de Aeronáutica

- Law No. 7,565 dated 19 December 1986

- and Regulamento Brasileiro de Homologação Aeronáutica (RBHA ) 39, applies to all aircraft registered in the Registro Aeronáutico Brasileiro. N o person may operate an aircraft to which this AD applies, unless it has previously complied with the requirements established herein.

- 100 STD, ERJ 190

- 100 LR, ERJ 190

- 100 IGW, ERJ 190

.

**CANCELLATION / REVISION:** Not applicable. **REASON:** It has been found the occurrence of damage on the rod end of the Main Landing Gear (MLG) retraction actuator. The ANAC is issuing this AD to prevent breakage of the MLG retracting actuator rod, which may result in MLG extension with no hydraulic damping and consequent damage to the locking mechanism and collapse of the MLG.

Since this condition may occur in other airplanes of the same type and affects flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with t his AD in the indicated time limit.

**REQUIRED ACTION:** Perform a General Visual Inspection (GVI) on the L eft H and (LH) and the R ight H and (RH) MLG retraction actuators.

**COMPLIANCE:** Required as indicated below, unless already accomplished. **(a)** Within 30 days after the effective date of thi s AD, perform a one

- time inspection to determine the part number (P/N) of the MLG retraction actuator on both sides of the airplane. Instead of inspectin g the MLG retraction actuator, a review of airplane maintenance records is acceptable if the detailed p art number of the MLG retraction actuator can be positively determined from that review

. **(1)** If no MLG retraction actuator having P/N 190

- 70980

- 403 is found: no further action is required by this paragraph **(a)** ; **(2)** If any MLG retraction actuator having P/N 190

- 70980

- 403 is found: a ccomplish with following AD requirements

. **(b)** For the MLG retraction actuator identified in paragraph **(a)(2)** of this AD , perform a GVI in accordance with “Part I” as described by the Embraer Service B ulletin (SB) N o. 190

- 32

- 0036, at the following interval s : **(1)** If the MLG retraction actuator has ac cumulated less than 3 , 500 F light C ycles (FC), perform the inspection required by paragraph **(b)** before the MLG retraction actuator logs 4 ,500 FC. **(2)** For the MLG retraction actuator that h as ac cumulated more than 3 , 500 FC, perform the inspection required by paragraph **(b)** within the next 1 , 000 FC.**CONTINUATION OF AD**  **N o**  **.: 2011 -**  **02 -**  **01 -**  **A MENDMENT**  **39 -**  **1328 PAGE N**  **o .:**  **2 /**  **2**

- 04E **(c )**  Repeat the GVI required by paragraph **(b)** of this AD every 3 , 500 FC of the MLG retraction actuator. **(d )**  If any discrepancy is found during the inspection required by paragraph **(b)** or **(c)** of this AD, including any movement between the actuator rod

- end and shock strut lug, the MLG retraction actuator and, if applicable, the anti

- rotation pin and the attachment bolt must be replaced within next 500 FC in accordance with “Part II” or “Part III” of the Embraer SB N o. 190

- 0036. **(e)** Before the MLG retraction actuators P/N 190

- 70980

- 403 logs 12,000 FC replace the actuators by new improved of P/N 190

- 70980

- 405 and modify the attachment points in accorda nce with “Part I” and “Part II” of Embraer SB No. 1 90

- 32

- 0037. **(f)** On the next MLG overhaul do the actions referred by paragraph **(e)** above, modify the attachment points in accordance with “Part III” of Embraer SB N o. 190

- 0037. Compliance with this para graph constitute s a final action for the requirements of this AD. **NOTE:** For the purpose of this AD, a G eneral V isual I nspection (GVI) is: "A visual examination of an interior or exterior area, installation or assembly to detect obvious damage, failure or i rregularity. 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 ins pection is made under normally avai lable 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 ma y be required to gain proximity to the area being checked. ”

The detailed ins tructions and procedures to accomplish this AD are described in the Embraer Service Bulletins N o. 190
