This AD applies to all The Boeing Company airplanes identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, certificated in any category.
(1) The Boeing Company Model 717-200 airplanes.
(2) The Boeing Company Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, and DC-10-40F airplanes; and Model MD-10-10F and MD-10-30F airplanes.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes; Model DC-10-10, DC-10-10F, DC- 10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40 and DC-10-40F airplanes; Model MD-10-10F and MD-10-30F airplanes; Model DC-9-81 (MD- 81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes; Model MD-88 airplanes; and Model MD-90-30 airplanes. This AD was prompted by reports of latent air data transducer degradation. This AD requires revising the maintenance or inspection program, as applicable, to incorporate special compliance items (SCIs). We are issuing this AD to prevent erroneous air data information, which could lead to a mid- air collision within reduced vertical separation minimum (RVSM) airspace.
Within 30 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, by incorporating the information specified in paragraphs (g)(1), (g)(2), or (g)(3) of this AD, as applicable. The initial compliance time for the tasks is within 18 months after the effective date of this AD.
(1) For Model 717-200 airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes; Model MD-88 airplanes; and Model MD-90-30 airplanes: Incorporate Special Compliance Item (SCI) 34-1, “Functional Test of the Captain and First Officer's Altimeter, of Appendix A—“SCIs” to Boeing Report No. MDC-92K9145, “Twinjet Special Compliance Items Report,” Revision M, dated February 5, 2013.
(2) For Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40 and DC-10-40F airplanes: Incorporate SCI 34-4, “Functional Test of the Captain and First Officer's Altimeter,” of Appendix A—“SCIs” to Boeing Report No. MDC-02K1003, “Trijet Special Compliance Item Report,” Revision K, dated February 1, 2013.
(3) For Model MD-10-10F and MD-10-30F airplanes: Incorporate SCI 34-4, “Functional Test of the Captain and First Officer's Altimeter, of Appendix A—“SCIs” to Boeing Report No. MDC-02K1003, “Trijet Special Compliance Item Report,” Revision K, dated February 1, 2013.
After accomplishment of the revision required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
