EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0100

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 aircraft to 

which an AD applies, except in accordance with the requirements 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].

Design Approval Holder’s Name:

FOKKER SERVICES B.V.

Type/Model designation(s):

F27 aeroplanes

TCDS Number: EASA.A.036

Foreign AD: Not applicable

Supersedure: None

ATA 28 Fuel – Fuel Tanks – Modification [Fuel Tank Safety]

Manufacturer(s): Fokker Aircraft B.V.

Applicability: F27 Mark 200, Mark 300, Mark 400, Mark 500, 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 tanks. 

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) SBF27-28-072

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 AOF27.043#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.
