Airworthiness Directive · Amendment 39-16342 · And 76: fuel and engine controls, respectively
Fokker Services B.V. Model F.28 Mark 0070 and 0100 Airplanes
This AD applies to Fokker Services B.V. Model F.28 Mark 0070 and Mark 0100 airplanes, certificated in any category, all serial numbers, if an actuator having part number (P/N) 9409122 or P/N 53-0013 is installed on one or both fuel crossfeed valves or one or both fuel fire shut-off valves.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For airplanes with an actuator having P/N 9409122 on one or both fuel crossfeed valves or one or both fuel fire shut-off valves: Within 30 days after the effective date of this AD, perform an operational test of, and application of grease on, the left-hand (LH) and right-hand (RH) fuel crossfeed valve actuators and fuel fire shut off valve actuators, in accordance with Part 1 of the Accomplishment Instructions of Fokker Service Bulletin SBF100-28-049, dated April 3, 2007.
(h) For airplanes equipped with an actuator having P/N 9409122 on one or both fuel crossfeed valves or one or both fuel fire shut-off valves: Within 7 days after completion of the actions required by paragraph (g) of this AD, and thereafter at intervals not to exceed 7 days, perform a general visual inspection of the applied grease layer on the LH and RH fuel crossfeed valve actuators and fuel fire shut off valve actuators, in accordance with Part 2 of the Accomplishment Instructions of Fokker Service Bulletin SBF100-28-049, dated April 3, 2007. If the layer of grease on any valve actuator is found to be less than 2 to 3 millimeters, before further flight, reapply grease, in accordance with Part 1 of the Accomplishment Instructions of Fokker Service Bulletin SBF100-28-049, dated April 3, 2007.
(i) For airplanes equipped with an actuator having P/N 9409122 on one or both fuel crossfeed valves or one or both fuel fire shut-off valves: Within 28 days after completion of the actions required by paragraph (g) of this AD, and thereafter at intervals not to exceed 28 days, perform an operational test of the LH and RH fuel crossfeed valve actuators and fuel fire shut off valve actuators, in accordance with Part 3 of the Accomplishment Instructions of Fokker Service Bulletin SBF100-28-049, dated April 3, 2007.
(j) During any of the tests required by paragraphs (g) and (i) of this AD, if a fuel fire shut-off valve actuator fails the operational test, before further flight, do the action specified in paragraph (j)(1) or (j)(2) of this AD.
(1) Do the replacement specified in paragraph (l) of this AD.
(2) Replace the valve actuator with a serviceable part having P/N 9409122, using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (or its delegated agent).
Note 1: Guidance on replacing the valve actuator with a serviceable part can be found in the Fokker 70/100 Aircraft Maintenance Manual.
(k) During any of the tests required by paragraphs (g) and (i) of this AD, if a fuel crossfeed valve actuator fails the operational test, before further flight, do the action specified in paragraph (k)(1) or (k)(2) of this AD.
(1) Do the replacement specified in paragraph (o) of this AD.
(2) Replace the valve actuator with a serviceable part having P/N 9409122, using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the EASA (or its delegated agent).
Note 2: Guidance on replacing the valve actuator with a serviceable part can be found in the Fokker 70/100 Aircraft Maintenance Manual.
For airplanes equipped with an actuator having P/N 9409122 on one or both fuel fire shut-off valves: Except as required by paragraph (j) of this AD, within 15 months after the effective date of this AD, replace each fuel fire shut-off valve actuator having P/N 9409122 with a fuel fire shut-off valve actuator having P/N 53-0027 and accomplish the associated modifications, in accordance with Part 1A or 1B, as applicable, of the Accomplishment Instructions of Fokker Service Bulletin SBF100-76-020, dated April 20, 2009. After installation of fuel fire shut-off valve actuators having P/N 53-0027 on an airplane, the requirements of paragraphs (g), (h), and (i) of this AD no longer apply to the fuel fire shut-off valve actuators installed on that airplane.
(m) For airplanes equipped with an actuator having P/N 53-0013 on one or both fuel fire shut-off valves: Within 15 months after the effective date of this AD, replace each fuel fire shut-off valve actuator having P/N 53-0013 with a fuel fire shut-off valve actuator having P/N 53-0027, in accordance with Part 2 of the Accomplishment Instructions of Fokker Service Bulletin SBF100-76-020, dated April 20, 2009.
(n) As of the effective date of this AD, do not install a fuel fire shut-off valve actuator having P/N 53-0013 on any airplane.
For airplanes equipped with an actuator having P/N 9409122 on one or both fuel crossfeed valves: Do the actions specified in paragraph (o)(1) or (o)(2) of this AD.
(1) Except as specified in paragraph (k)(1) of this AD, within 12 months after the effective date of this AD, replace each fuel crossfeed valve actuator having P/N 9409122 with a fuel crossfeed valve actuator having P/N 53-0013, and before further flight, accomplish the associated modifications, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-28-046, dated March 27, 2008; and do the replacement required by paragraph (p) of this AD at the time specified in paragraph (p) of this AD. After installing fuel crossfeed valve actuators having P/N 53-0013 on an airplane, the requirements of paragraphs (g), (h), and (i) of this AD no longer apply to the fuel crossfeed valve actuators installed on that airplane.
(2) Within 12 months after the effective date of this AD, replace each fuel crossfeed valve actuator having P/N 9409122 with a fuel crossfeed valve actuator having P/N 53-0027, in accordance with Part 1A or 1B, as applicable, of the Accomplishment Instructions of Fokker Service Bulletin SBF100-28-061, dated April 20, 2009. After installing fuel crossfeed valve actuators having P/N 53-0027 on an airplane, the requirements of paragraphs (g), (h), and (i) of this AD no longer apply to the fuel crossfeed valve actuators installed on that airplane.
(p) For airplanes equipped with an actuator having P/N 53-0013 on one or both fuel crossfeed valves: Within 18 months after the effective date of this AD, replace each fuel crossfeed valve actuator having P/N 53-0013 with a fuel crossfeed valve actuator having P/N 53-0027, in accordance with Part 2 of the Accomplishment Instructions of Fokker Service Bulletin SBF100-28-061, dated April 20, 2009. After installing fuel crossfeed valve actuators having P/N 53-0027 on an airplane, the requirements of paragraphs (g), (h), and (i) of this AD no longer apply to the fuel crossfeed valve actuators installed on that airplane.
(q) After accomplishing the actions specified in paragraph (p) of this AD, do not install any fuel crossfeed valve actuator having P/N 53-0013 on any airplane.
Note 3: This AD differs from the MCAI and/or service information as follows: Although paragraph (5) of EASA AD 2007-0122, dated May 3, 2007, allows operating the airplane in accordance with the Master Minimum Equipment List (MMEL) Item 28-23-1 of MMEL Fokker 70/MMEL Fokker 100, paragraph (l) of this AD requires replacing affected valves before further flight.
