EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0271

Date: 12 December 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):

F28 aeroplanes

TCDS Number: EASA.A.037

Foreign AD: Not applicable

Supersedure: None

ATA 57 Wings – Trailing Edge Rib at Wing Station 8700 – Inspection

Manufacturer(s): Fokker Aircraft B.V.

Applicability: F28 Mark 0070 and Mark 0100 aeroplanes, all serial numbers.

Reason: Service experience with the Fokker 100 type design has shown that cracking can 

occur in the secondary structure of the wing at station 8700, rib Part Number (P/N)

D15445-013/-014 (or lower dash number) in the trailing edge section. The 

hydraulic actuator assembly, hydraulic lines, the cable pulleys, the anti-upfloat 

quadrant and the associated mechanical linkages including flutter dampers are all 

positioned in the affected area, between wing stations 8200 and 9270.

This condition, if not detected and corrected, could lead to failure of the affected 

rib, possibly resulting in reduced control of the aeroplane.

To address this potential unsafe condition, Fokker Services published Service 

Bulletin (SB) SBF100-57-048, which provides inspection instructions to detect any 

cracks in the affected area.

For the reasons described above, this AD requires a one-time inspection of the 

trailing edge rib at wing station 8700 and, depending on findings, accomplishment 

of applicable corrective action(s).

This AD is considered to be an interim action and further AD action may follow, 

possibly to introduce new ALS tasks, if justified by the inspection results.

Effective Date: 29 December 2014
