Airworthiness Directive · Amendment 39-19283 · Stabilizers
Boeing Airplanes
This AD applies to The Boeing Company Model 717-200 airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 717-55A0012, Revision 1, dated April 11, 2018.
We are superseding Airworthiness Directive (AD) 2016-09-05, which applied to certain The Boeing Company Model 717-200 airplanes. AD 2016-09-05 required a detailed inspection for distress of the vertical stabilizer leading edge skin, and related investigative and corrective actions if necessary. It also required, for certain airplanes, repetitive inspections of the front spar cap for any loose or missing fasteners, or any cracking, and related investigative and corrective actions if necessary. This AD requires repetitive inspections for distress, cracking, and loose or missing fasteners in the vertical stabilizer leading edge skin and front spar cap, with new compliance times for certain airplanes. This AD was prompted by reports of cracking in the leading edge of the vertical stabilizer and front spar web. We are issuing this AD to address the unsafe condition on these products.
Except as required by paragraph (h) of this AD, at the applicable time specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 717-55A0012, Revision 1, dated April 11, 2018, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 717-55A0012, Revision 1, dated April 11, 2018.
(1) For purposes of determining compliance with the requirements of this AD: Where Boeing Alert Service Bulletin 717-55A0012, Revision 1, dated April 11, 2018, uses the phrase “the Revision 1 issue date of this service bulletin,” this AD requires using the effective date of this AD.
(2) Where Boeing Alert Service Bulletin 717-55A0012, Revision 1, dated April 11, 2018, specifies contacting Boeing, and specifies that action as RC: This AD requires repair using a method approved in accordance with the procedures specified in paragraph (j) of this AD.
