Airworthiness Directive · Amendment 39-18416 · Fuel
Fokker Services B.V. Airplanes
This AD applies to Fokker Services B.V. Model F.27 Mark 200, 300, 400, 500, 600, and 700 airplanes, certificated in any category, all serial numbers.
We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F.27 Mark 200, 300, 400, 500, 600, and 700 airplanes. This AD was prompted by a design review conducted by Fokker Services B.V. that indicated no controlled bonding provisions were present on many critical locations outside the fuel tank or connected to the fuel tank wall. This AD requires installing the additional bonding provisions, and revising the maintenance or inspection program, as applicable, by incorporating fuel airworthiness limitation items and critical design configuration control limitations. We are issuing this AD to prevent an ignition source in the fuel tank vapor space, which could result in a fuel tank explosion and consequent loss of the airplane.
Within 24 months after the effective date of this AD, install additional bonding provisions, in accordance with the Accomplishment Instructions of Fokker F27 Proforma Service Bulletin SBF27-28-072, Revision 1, dated March 6, 2014, including Fokker F27 Service Bulletin Appendix SBF27-28-072/APP01, dated July 17, 2014, including List of Drawings/Part Lists, dated July 17, 2014.
At the later of the times specified in paragraphs (h)(1) and (h)(2) of this AD: Revise the airplane maintenance or inspection program, as applicable, by incorporating the fuel airworthiness limitations items and critical design configuration control limitations as identified in Fokker Manual Change Notification—Maintenance Documentation MCNM-F27-027, dated September 9, 2014.
(1) Before further flight after accomplishing the installation required by paragraph (g) of this AD,
(2) Within 30 days after the effective date of this AD.
After the maintenance or inspection program, as applicable, has been revised as required by paragraph (h) of this AD, no alternative actions (e.g., inspections), intervals, and/or CDCCLs may be used unless the actions, intervals, and/or CDCCLs are approved as an alternative method of compliance in accordance with the procedures specified in paragraph (j)(1) of this AD.
