**CANCELLATION / REVISION:** This AD cancels and supersedes the AD No.2010

- 06

- 02

– Amdt 39

- 1299, dated 16 Jul. 2010, and is being issued to change its compliance paragraph.

**REASON:** It has been found the occurrence of drill marks at the lower ring region of the rear pressure bulkhead between circumferential splice joint and rear skin located bet ween stringers 12 and 13. These marks may result in formation of fatigue cracks accelerated by corrosion reducing the structur al strength of the rear pressure bulkhead, which may cause a sudden decompression of the passenger cabi n.

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:** Inspection and repair, if necessary, of d rill marks at lower ring region of the rear pressure bulkhead, between circumferential splice joint and rear skin

.

**COMPLIANCE:** Required as indicated below, unless already accomplished. Before the aircraft logs 20000 flight cycles (FC) , carry out detailed visual inspection (DET) for signs of drill marks at the left (LH) and right (RH) lower ring region of the rear pressur e bulkhead, between circumferential splice joint and rear skin between stringers 12 and 13. If drill m arks are found repair then before th e next flight. **NOTE:** For the purpose of this AD, a detailed inspection (DET) is: "An intensive examination of a specific item, installation or assembly to detect damage, failure or irregularity. Available lightin g is normally supplemented with a direct so urce of good lighting at an intensity deemed appropriate. Inspection aids such as mirrors, magnifying lenses, etc., may be necessary. Surface cleaning and ela borate access procedures may be required."

The detailed instructions and procedures to accomplish this AD are described in the Embraer Service Bulletin No.190

- 0042, original issue , or further revisions approved by the ANAC.

Record compliance with this AD in the applicable maintenance log book.**CONTINUATION OF AD**  **N o**  **.: 2010 -**  **06 -**  **02R1**
