EASA AIRWORTHINESS DIRECTIVE

AD No.: 2012-0242

Date: 12 November 2012

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):

F28 aeroplanes

TCDS Number: EASA.A.037

Foreign AD: Not applicable

Supersedure: None

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

Manufacturer(s): Fokker Aircraft B.V.

Applicability: F28 Mark 0070 and F28 Mark 0100 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 design review conducted by Fokker Services on the Fokker 70 and Fokker 

100 in response to these regulations revealed that no controlled bonding 

provisions are present on a number of critical locations, inside the fuel tank or 

connected to the fuel tank wall.

This condition, if not corrected, may create an ignition source in the fuel tank 

vapour space, possibly resulting in a fuel tank explosion and consequent loss of 

the aeroplane.

For the reasons described above, this AD requires the installation of additional 

bonding provisions and, subsequently, the implementation of the associated 

Fuel Airworthiness Limitation Items (ALI) and Critical Design Configuration 

Control Limitations (CDCCL).

Effective Date: 26 November 2012
