**CANCELLATION / REVISION:**

Not applicable.

**REASON:** During ERJ 190 airplane full scale fatigue test, cracks were found in some structural
comp onents of the airplane. Analysis of th ese cracks resulted in modifications on the airplane Airworthiness Limitation Items (ALI), to include new inspections tasks or modification of existing o nes and its respective thresholds and intervals.

Failure to insp ect these components according to the new tasks

, thresholds and intervals could prevent a timely detection of fatigue crack s. Undetected fatigue cracks in these areas could adversely affect the structural integrity of these airplanes.

Since this condition may occur in other air planes 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:** Updating of the air

plane approved mai ntenance program according to the Maintenance Review Board Report (MRBR).

**COMPLIANCE:** Required as indicated below, unless already accomplished.
**(a)** Within the next 90 days after the effective date of this AD, modify the airplane approved maintenance progra m to include the tasks according to the table below. These tasks are listed on Temporary Revisions (TR) 2

- 6, dated 12 Feb. 2008 of the Embraer 190 MRB Report (MRB

- 1928), or further MRBR revisions approved by ANAC, with the
t hresholds and intervals stated at th ese document s

. **(b)** The initial compliance time start s from the applicable threshold times and the repetitive inspections must be accomplished thereafter at the interval specified in the correspondent tasks of the MRBR,

o bserving for each task, the pre and pos

- mod condition of the associated service bulletin, if applicable. **(c)** In case the airplane has exceeded the new thresholds after accomplishment of paragraph (a)
