EASA AIRWORTHINESS DIRECTIVE

AD No.: 2015-0091

Date: 26 May 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):

F28 aeroplanes

TCDS Number: EASA.A.037

Foreign AD: Not applicable

Supersedure: None

ATA 27 Flight Controls – Elevator Tension Control Regulator – Inspection

Manufacturer(s): Fokker Aircraft B.V.

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

Reason: During the accomplishment of the taxi-out checklist on an F28 Mark 0100 

aeroplane, the flight crew noticed that the elevator movement was partially 

obstructed. The subsequent investigation revealed that this was due to rotation 

of the flight control lock adjuster bracket, which had come loose from the 

elevator tension control regulator. Two of the three attachment bolts were 

found broken, and two nuts were missing. Although no root cause could be 

identified for the absence of these nuts, they are considered as the main 

contributor to the occurrence. 

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

elevator mechanism, possibly resulting in reduced control of the aeroplane. 

To address this potential unsafe condition, Fokker Services published Service 

Bulletin (SB) SBF100-27-095 which provides instructions to detect and correct 

any discrepancies, and to re-install missing or broken parts (if any).

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

elevator tension control regulator and, depending on findings, accomplishment 

of applicable corrective action(s).

More information on this subject can be found in Fokker Services All Operators 

Message AOF100.198.
