Models named: 717-200. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all The Boeing Company Model 717-200 airplanes, certificated in any category.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

At the applicable time specified in paragraph (g)(1) or (g)(2) of this AD, do a general visual inspection and a high frequency eddy current (HFEC) inspection for cracking of the left-side and right-side overwing frames at station 737, and do all applicable corrective actions, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 717-53A0036, dated August 12, 2013, except as required by paragraph (h)(3) of this AD. Do all applicable corrective actions before further flight. Except as required by paragraph (h)(2) of this AD, repeat the inspections thereafter at the applicable time specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 717-53A0036, dated August 12, 2013. (1) For Group 1, Configuration 1 airplanes identified in Boeing Alert Service Bulletin 717-53A0036, dated August 12, 2013: At the time specified in table 1 of paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 717-53A0036, dated August 12, 2013, except as provided by paragraph (h)(1) of this AD. (2) For Group 1, Configuration 2 airplanes identified in Boeing Alert Service Bulletin 717-53A0036, dated August 12, 2013: At the applicable time specified in paragraph (g)(2)(i) or (g)(2)(ii) of this AD. (i) For airplanes on which the overwing frame has not been replaced: Within 9,300 flight cycles after the inspections specified in Boeing Multi Operator Message (MOM) MOM-MOM-13-0375-01B, dated May 9, 2013, were accomplished. (ii) For airplanes on which the overwing frame has been replaced: Within 12,000 flight cycles after replacing the frame.

Unsafe condition

This AD was prompted by multiple reports of cracking in the overwing frames. We are issuing this AD to detect and correct such cracking, which could result in a severed frame and might increase the loading of adjacent frames, resulting in damage to the adjacent structure and consequent loss of structural integrity of the airplane.

Affected ADs

None.
