EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2009-0168 

Date: 03 August 2009 

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 EC 1702/2003, Part 21A.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]. 

Type Approval Holder’s Name : 

Fokker Services B.V. 

Type/Model designation(s) : 

F28 Mark 0070 and Mark 0100 aeroplanes 

TCDS Number : EASA.A.037 

Foreign AD : Not applicable 

Supersedure : This AD supersedes EASA AD 2008-0193 dated 21 October 2008. 

ATA 76 Engine Controls – Fuel Fire Shut-off Valve Actuator – 

Replacement 

Manufacturer(s): Fokker Aircraft B.V. 

Applicability: 

F28 Mark 0070 and Mark 0100 aeroplanes, all serial numbers, if an actuator 

Part Number (P/N) 9409122 or P/N 53-0013 is installed on one or both fuel 

fire shut-off valves. 

Reason: 

Due to their position on the aeroplane, fuel fire shut-off valve actuators P/N 

9409122 are susceptible to freezing, which has an adverse effect on the 

operation of the valve. Also, due to various causes, the failure rate of actuator 

P/N 9409122 is higher than expected. Failure or freezing of the actuator may 

prevent the flight crew to close the fuel fire shut-off valve in case of an engine 

fire. 

Aeroplanes serial numbers 11244 through 11441 were delivered from the 

production line with actuators P/N 9401037 (“chimney type”) installed. 

However, on some aeroplanes, these actuators have subsequently been 

replaced in service with actuators P/N 9409122 (using mounting blocks P/N 

7923505) on one or both fuel fire shut-off valves. As a result, those 

aeroplanes are also affected by this unsafe condition. 

To address and correct this unsafe condition, EASA issued AD 2008-0193, 

requiring the replacement of all P/N 9409122 fuel fire shut-off valve actuators 

with new actuators developed by the manufacturer Eaton Aerospace, P/N 53-

0013, which have improved reliability and are less susceptible to freezing. 

Following the introduction of actuator P/N 53-0013 in service, Eaton 

Aerospace reported manufacturing and design errors on actuators with P/N 

53-0013. As a result of these errors, the top-cap of the actuator may become 

loose, possibly leading to actuator failure. Eaton Aerospace has eliminated

these problems by introducing a new actuator P/N 53-0027 and Fokker 

Services have published SBF100-76-020 to introduce these improved 

actuators on aeroplanes. 

As a consequence of EASA AD 2008-0193, both P/N 9409122 and P/N 53-

0013 fuel fire shut-off valve actuators are currently installed on aeroplanes 

affected by this AD. 

For the reasons described above, this EASA AD supersedes AD 2008-0193 

and requires the installation of new P/N 53-0027 actuators. This AD also 

prohibits the installation of P/N 53-0013 actuators in accordance with 

SBF100-76-018 (which has been cancelled), as previously required by EASA 

AD 2008-0193.

Effective Date: 17 August 2009 

Required Action(s) 

and Compliance 

Time(s): 

Required as indicated, unless accomplished previously: 

(1) Within the next 15 months after the effective date of this AD, accomplish 

either paragraph (1.1) or (1.2) below, as applicable to aeroplanes 

configuration:

(1.1) For aeroplanes in pre-SBF100-76-018 configuration: Remove 

each fuel fire shut-off valve actuator with P/N 9409122 from the 

aeroplane and replace it with a fuel fire shut-off valve actuator P/N 

53-0027 and accomplish the associated modifications in 

accordance with Part 1A or 1B, as applicable, of the 

Accomplishment Instructions of Fokker Services SBF100-76-020. 

(1.2) For aeroplanes in post-SBF100-76-018 configuration: Remove 

each fuel fire shut-off valve actuator with P/N 53-0013 from the 

aeroplane and replace it with a fuel fire shut-off valve actuator P/N 

53-0027 in accordance with Part 2 of the Accomplishment 

Instructions of Fokker Services SBF100-76-020. 

(2) After the effective date of this AD, do not install a P/N 53-0013 fuel fire 

shut-off valve actuator on any aeroplane. 

Note: After installation of P/N 53-0027 fuel fire shut-off valve actuators on an 

aeroplane, the requirements of EASA AD 2007-0122 no longer apply to the 

fuel fire shut-off valve actuators installed on that aeroplane.
