EASA AIRWORTHINESS DIRECTIVE

AD No.: 2015-0029

Date: 24 February 2015

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 EU 1321/2014 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 [EU 1321/2014 

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: This AD supersedes EASA AD 2014-0105 dated 07 May 2014.

ATA 28 Fuel – Fuel Airworthiness Limitations – Implementation

Manufacturer(s): Fokker Aircraft B.V.

Applicability: F27 Mark 200, 300, 400, 500, 600 and 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 F27 design in response to these regulations identified a 

number of Fuel Airworthiness Limitation items (ALI) and Critical Design 

Configuration Control Limitations (CDCCL) items to prevent the development of 

unsafe conditions within the fuel system.

To introduce these Fuel ALI and CDCCL items, Fokker Services published 

Service Bulletin (SB) F27/28-070 and EASA issued AD 2006-0207, requiring the 

implementation of these Fuel ALI and CDCCL items. That AD was later revised to 

make reference to SBF27-28-070R1 and to specify that the use of later SB

revisions was acceptable.

In 2014, Fokker Services issued Revision 2 of SBF27-28-070 to update the Fuel 

ALI and CDCCL items and to consolidate Fuel ALI and CDCCL items contained in 

a number of other SBs. Consequently, EASA issued AD 2014-0105, superseding

AD 2006-0207R1 and requiring the implementation of the updated Fuel ALI and 

CDCCL items.

Since that AD was issued, Fokker Services issued Revision 3 of SBF27-28-070,

primarily to introduce 2 additional CDCCL items.

For the reason described above, this AD retains the requirements of EASA AD 

2014-0105, which is superseded, and requires implementation of the updated 

Fuel ALI and CDCCL items.

overhauled, repaired, accessed, removed and/or replaced, as 

applicable, ensure that components remain installed on the aeroplane 

in compliance with an approved configuration.

(1.3) If, during any action as required by paragraph (1.1) or (1.2) of this AD,

as required by paragraphs (1.1) and (1.2) of this AD.

(3) Within 12 months after the effective date of this AD, revise the approved 

aircraft maintenance programme (AMP), on the basis of which the operator or

by incorporating the Fuel ALI tasks, CDCCL items and associated thresholds, 

intervals and instructions as described in Fokker Services SBF27-28-070 

Revision 3.

(4) Compliance with the requirements of paragraph (3) constitutes compliance
