AD 2018-10-08 Airworthiness Directives; Boeing Airplanes
Models named: 717-200. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
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.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
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.
Unsafe condition
This AD was prompted by multiple reports of the vertical stabilizer leading edge showing signs of fastener distress, multiple cracked or severed front spar caps, and cracks in the left skin of the vertical stabilizer leading edge and in the front spar web, discovered during initial inspections required by AD 2016-09-05. We have determined that a revised compliance time is needed for airplanes on which the initial inspection has not been done as specified in AD 2016-09-05. We are issuing this AD to address cracking in the vertical stabilizer leading edge and front spar cap, which may result in the structure becoming unable to support limit load, and may lead to loss of the vertical stabilizer.
Affected ADs
This AD replaces AD 2016-09-05, Amendment 39-18503 (81 FR 26673, May 4, 2016) (“AD 2016-09-05”).
