Models named: MD-88. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all The Boeing Company Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes, and Model MD-88 airplanes, certificated in any category.

Compliance

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

Required actions

Except as required by paragraph (h)(1) and (h)(2) of this AD, at the applicable time specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin MD80-57A244, dated March 3, 2016: Do an eddy current high frequency (ETHF) inspection for any cracking in the left and right side center wing lower skin, and do all applicable corrective actions; except as required by paragraph (h)(3) of this AD. Do all applicable corrective actions before further flight. Repeat the inspection thereafter at the intervals specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin MD80-57A244, dated March 3, 2016.

Unsafe condition

This AD was prompted by reports of cracking at certain stringers, associated end fittings, and skins in the center wing fuel tank where the stringers meet the end fittings. We are issuing this AD to detect and correct cracking in the center wing lower skin. Such cracking could cause structural failure of the wings.

Affected ADs

None.
