Airworthiness Directive · Amendment 39-22316 · Stabilizers
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2007-10- 04, which applied to all McDonnell Douglas Model DC-9-81 (MD-81), DC-9- 82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 airplanes. AD 2007-10-04 required repetitive inspections to detect cracks in the horizontal stabilizer, and related investigative and corrective actions if necessary. Since the FAA issued AD 2007-10-04, it has been determined that certain compliance times and repetitive intervals must be reduced to address the unsafe condition. This AD continues to require the actions specified in AD 2007-10-04 with revised compliance times for certain actions. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin MD80-55A065, Revision 2, dated October 11, 2021, do an eddy current inspection to detect any cracking in the horizontal stabilizer and do all applicable repetitive inspections and corrective actions, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin MD80-55A065, Revision 2, dated October 11, 2021. Do all applicable repetitive inspections and corrective actions at the times specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin MD80-55A065, Revision 2, dated October 11, 2021.
(1) Where the Compliance Time columns of the tables in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin MD80-55A065, Revision 2, dated October 11, 2021, use the phrase “the original issue date of this service bulletin,” this AD requires using May 23, 2007 (the effective date of AD 2007-10-04).
(2) Where the Compliance Time columns of the tables in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin MD80-55A065, Revision 2, dated October 11, 2021, use the phrase “the Revision 2 date of this service bulletin,” this AD requires using “the effective date of this AD.”
