Airworthiness Directive · Amendment 39-15528 · McDonnell Douglas Model 717-200 Airplanes
McDonnell Douglas Model 717-200 Airplanes
This AD applies to McDonnell Douglas Model 717-200 airplanes, certificated in any category; as identified in Boeing Alert Service Bulletin 717-38A0004, Revision 1, dated August 15, 2007; excluding fuselage number 5005.
We are adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires installing an additional support bracket for the gray water drain hose; replacing the screw of the support bracket with a new screw for the potable water supply hose; installing a spacer; doing a detailed inspection to detect interference or wear damage on hoses, lines and/or cables; and doing corrective actions if necessary. This AD results from reports of interference between the potable water supply hose and/or gray water drain hose at the aft lavatories and the fuel line and/or power feeder cables of the auxiliary power unit (APU) located below the aft cabin floor. We are issuing this AD to prevent interference and chafing between the potable water supply hose and/or gray water hose and the fuel line and/or power feeder cables of the APU, which could cause arcing and sparking, and/or fuel leaking, and consequent fire.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 27 months after the effective date of this AD, do the installations, replacement, inspections, and applicable corrective actions by accomplishing all the actions specified in the Accomplishment Instructions of Boeing Alert Service Bulletin 717-38A0004, Revision 1, dated August 15, 2007; except as provided by paragraph (g) of this AD. The applicable corrective actions must be done before further flight.
(g) If any discrepancy is found during any inspection required by this AD, and Boeing Alert Service Bulletin 717-38A0004, Revision 1, dated August 15, 2007, specifies to contact Boeing for appropriate action: Before further flight, repair the discrepancy in accordance with the procedures specified in paragraph (i) of this AD.
Actions accomplished before the effective date of this AD in accordance with Boeing Alert Service Bulletin 717-38A0004, dated December 6, 2006, is considered acceptable for compliance with the corresponding actions specified in paragraph (f) of this AD.
