BRAZILIAN AIRWORTHINESS DIRECTIVE

AD No.: 2010-06-01R1 Effective Date: 25 Aug. 2010

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. 2010-06-01R1 - EMBRAER - Amendment 39-1310.

APPLICABILITY:

This Airworthiness Directive is applicable to Embraer Models ERJ 170-100 STD, ERJ 

170-100 LR, ERJ 170-100 SU, ERJ 170-100 SE, ERJ 170-200 STD, ERJ 170-200 LR and ERJ 170-200 

SU airplanes with serial numbers 17000002, 17000004 thru 17000013, 17000015 thru 17000212, 

17000216 thru 17000233, 17000236, 17000269, 17000281 thru 17000291, and 17000293.

CANCELLATION / REVISION:

This AD cancels and supersedes the AD No.2010-06-01 – Amdt 39-1298, 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 between stringers 12 and 13. 

These marks may result in formation of fatigue cracks accelerated by corrosion reducing the structural 

strength 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 exists 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:

Required as indicated below, unless already accomplished.

Before the airplane 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 pressure 

bulkhead, between 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, 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 detailed instructions and procedures to accomplish this AD are described in the 

Embraer Service Bulletin No.170-53-0082, original issue, or further revisions approved by the ANAC.

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