- 0 10 0

Date: 30 April 2014

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and of the European third countries that participate in the activities of EASA under Article 66 of that Regulation.

This AD is issued in accordance with EU 748/2012, Part 21.A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate an air craft to which an AD applies, except in accordance with the requ irements of that AD, unless otherwise specified by the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption].

### ATA 28 Fuel

– Fuel Tank s
– Modification [Fuel Tank Safety]

Manufacturer(s): Fokker Aircraft B.V.

Applicability: F2 7 Mark 200

, Mark 300, Mark 400, Mark 50 0, Mark 600 and Mark 700 aeroplanes

, all serial numbers

.

Reason: Prompted by an accident of a Boeing 747

- 131 (flight TWA800), the FAA published Special Federal Aviation Regulation (SFAR) 88, and the Joint Aviation Authorities (JAA) published Interim Policy INT/POL/25/12. The review conducted by Fokker Services on the Fokker 27 design in response to these regulations revealed that no controlled bonding provisions are present on a number of critical locations outside the fuel tank s

. This condition, if not corrected, could create an ignition source in the fuel tank vapour space, possibly resulting in a fuel tank explosion and consequent loss of the aeroplane. To address this potential unsafe condition, Fokker Services developed a set of bonding modifications

, introduced with Service Bulletin (SB) SBF 27

- 28

- 072 Revision 1 (R1) , that do not require opening of the fuel tank access panels. More information on this subject can be found in Fokker Services All Operators Message AOF 27.043#03. For the reasons described above, this AD requires installation of additional bonding provisions that do not require opening of the fuel tank access panels.
