Airworthiness Directive · Amendment 39-18353 · Fuel
Fokker Services B.V. Airplanes
This AD applies to Fokker Services B.V. Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes, certificated in any category, all serial numbers.
We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes. This AD was prompted by a design review, which revealed that no controlled bonding provisions are present on a number of critical locations outside the fuel tank. This AD requires installing additional and improved fuel system bonding provisions, and revising the airplane 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 and improved fuel system bonding provisions, in accordance with the Accomplishment Instructions of Fokker F28 Appendix SB SBF28-28-059/APP01, dated July 15, 2014, of Fokker F28 Proforma Service Bulletin SBF28-28-059, Revision 1, dated July 15, 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 limitation items and critical design configuration control limitations (CDCCLs) specified in paragraph 1.L.(1)(b) of Fokker F28 Appendix SB SBF28-28-059/APP01, dated July 15, 2014, of Fokker F28 Proforma Service Bulletin SBF28-28-059, Revision 1, dated July 15, 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 incorporating the revision required by paragraph (h) of this AD, no alternative actions (e.g., inspections), intervals, or CDCCLs may be used unless the actions, intervals, or CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j)(1) of this AD.
