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

Within 700 flight cycles or 6 months after the effective date of this AD, whichever occurs first, do a detailed inspection for cracking on the left and right sides of the forward and aft surfaces of the cant station 1463 bulkhead (for Model DC-9-81 (MD-81), DC-9-82 (MD-82), and DC-9-83 (MD-83) airplanes, and Model MD-88 airplanes) and cant station 1254 bulkhead (for Model DC-9-87 (MD-87) airplanes); and do all applicable corrective actions; in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin MD80-53A316, dated December 15, 2016, except as required in paragraph (h) of this AD. Do all applicable corrective actions before further flight.

Unsafe condition

This AD was prompted by reports of cracking of various structures at the cant station 1463 bulkhead and at the cant station 1254 bulkhead. We are issuing this AD to detect and correct cracking at the cant station 1463 bulkhead and cant station 1254 bulkhead, which could result in reduced structural integrity of the airplane.

Affected ADs

None.
