BRAZILIAN AIRWORTHINESS DIRECTIVE

AD No.: 2011-02-01 Effective Date: 12 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. No person may operate an aircraft to which 

this AD applies, unless it has previously complied with the requirements established herein.

AD No. 2011-02-01 - EMBRAER - Amendment 39-1328.

APPLICABILITY:

This Airworthiness Directive (AD) applies to Embraer airplanes models ERJ 190-100 

STD, ERJ 190-100 LR, ERJ 190-100 IGW, ERJ 190-100 ECJ, ERJ 190-100 SR, ERJ 190-200 STD, ERJ 

190-200 LR and ERJ 190-200 IGW; all serial numbers.

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 this AD in 

the indicated time limit.

REQUIRED ACTION:

Perform a General Visual Inspection (GVI) on the Left Hand (LH) and the Right Hand 

(RH) MLG retraction actuators. 

COMPLIANCE:

Required as indicated below, unless already accomplished.

(a) Within 30 days after the effective date of this 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 inspecting the 

MLG retraction actuator, a review of airplane maintenance records is acceptable if the detailed part 

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: accomplish 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 Bulletin (SB) No. 190-32-0036, at the 

following intervals:

(1) If the MLG retraction actuator has accumulated less than 3,500 Flight Cycles (FC), perform the 

inspection required by paragraph (b) before the MLG retraction actuator logs 4,500 FC.

(2) For the MLG retraction actuator that has accumulated more than 3,500 FC, perform the 

inspection required by paragraph (b) within the next 1,000 FC.
CONTINUATION OF AD No.: 2011-02-01 - AMENDMENT 39-1328 PAGE No.: 2/2

Form F-900-04E

(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 No. 190-32-0036.

(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 accordance with “Part I” and 

“Part II” of Embraer SB No. 190-32-0037.

(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 No. 190-32-0037. Compliance with this paragraph 

constitutes a final action for the requirements of this AD.

NOTE: For the purpose of this AD, a General Visual Inspection (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 droplight, 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.”

The detailed instructions and procedures to accomplish this AD are described in the 

Embraer Service Bulletins No. 190-32-0036 and 190-32-0037 original issues, or their respective further 

revisions approved by the ANAC.

Record compliance with this AD in the applicable maintenance log book.
