**REASON:** It has been found the occurrence of dril l marks at the lower ring region of the rear pressure bulkhead between circumferential splice joint and rear skin located between stringers 12 an d 13. These marks may result in formation of fatigue cracks accelerated by corrosion reducing the structur al st rength of the rear pressure bulkhead, which may cause a sudden decompression of the passenger cabin.

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

.

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

.

**COMPLIANCE:** Requ ired as indicated below, unless already accomplished. Before the air

plane 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, b etween circumferential splice joint and rear skin between stringers 12 and 13. If drill marks are found repair then before the next flight. **NOTE:** For the purpose of this AD, a detailed inspection (DET) is: "An intensive examination of a specific item, ins tallation 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 necessar y. Surface cleaning and elaborate access procedures may be required."

The detailed instructions and procedures to accomplish this AD are described in the Embraer Service Bulletin No.170

- 0082, original issue , or further revisions approved by the ANAC.
