AD 2011-07-12 Airworthiness Directives; Fokker Services B.V. Model F.27 Mark 050 Airplanes

Models named: F.27 Mark 050. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to Fokker Services B.V. Model F.27 Mark 050 airplanes; certificated in any category; serial numbers 20133 through 20335 inclusive; except those with inboard fuel tanks installed. Note 1: This AD requires revisions to certain operator maintenance documents to include new actions ( e.g., inspections) and/or critical design configuration control limitations (CDCCLs). Compliance with these actions and/or CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval of an alternative method of compliance (AMOC) according to paragraph (n) of this AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane.

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Inspection (g) Within 6 months after the effective date of this AD: Inspect the part numbers of each fuel pipe (two in each nacelle), in accordance with Part 1 of the Accomplishment Instructions of Fokker Service Bulletin SBF50-28-028, Revision 1, dated September 15, 2010. (h) If, as a result of the inspection required by paragraph (g) of this AD, fuel pipe part numbers other than those specified in Part 1 of the Accomplishment Instructions of Fokker Service Bulletin SBF50-28-028, Revision 1, dated September 15, 2010, are found to be installed: Before further flight, do a general visual inspection to determine the clearance between the fuel pipes and the parts of the main landing gear, and for chafing marks, in accordance with Part 2 of the Accomplishment Instructions of Fokker Service Bulletin SBF50-28-028, Revision 1, dated September 15, 2010. Fuel Pipe Replacement (i) If, during the inspection required by paragraph (h) of this AD, the measured clearance is less than or equal to 3.0 mm and greater than 1.5 mm for one or more fuel pipes, and no chafing marks are found: Within 24 months after the effective date of this AD, install new fuel pipes in both engine nacelles, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF50-28-031, Revision 1, dated September 15, 2010. (j) If, during the inspection required by paragraph (h) of this AD, the measured clearance is less than or equal to 1.5 mm for one or more fuel pipes, or chafing marks are found on one or more fuel pipes: Before further flight, install new fuel pipes in both engine nacelles, in accordance with the Accomplishment Instructions of Fokker's Service Bulletin SBF50-28-031, Revision 1, dated September 15, 2010. Maintenance Program Revision To Add Fuel Airworthiness Limitation (k) Within 6 months after the effective date of this AD, revise the airplane maintenance program by incorporating the limitations specified in paragraphs (k)(1) and (k)(2) of this AD. (1) The CDCCL specified in paragraph 1.L.(1)(c) of Fokker Service Bulletin SBF50-28-031, Revision 1, dated September 15, 2010. (2) The fuel airworthiness limitation specified in paragraph 1.L.(1)(c) of Fokker Service Bulletin SBF50-28-028, Revision 1, dated September 15, 2010. The initial compliance time for doing the inspection is within 4,800 flight hours after doing the inspection required by paragraph (h) of this AD. No Alternative Actions, Intervals, and/or CDCCLs (l) After accomplishing the revision required by paragraph (k) of this AD, no alternative actions ( e.g., inspection, interval) and/or CDCCLs may be used unless the actions, intervals, and/or CDCCLs are approved as an AMOC in accordance with the procedures specified in paragraph (n) of this AD. Credit for Actions Accomplished in Accordance With Previous Service Information (m) Actions accomplished prior to the effective date of this AD, in accordance with Fokker Service Bulletin SBF50-28-028, dated May 20, 2010; or Service Bulletin SBF50-28-031, dated May 20, 2010; as applicable; are acceptable to comply with the corresponding requirements of this AD. FAA AD Differences Note 2: This AD differs from the MCAI and/or service information as follows: Although EASA Airworthiness Directive 2010-0197, dated October 1, 2010, specifies both revising the maintenance program to include airworthiness limitations, and doing certain repetitive actions (e.g., inspections) and/or maintaining CDCCLs, this AD only requires the revision. Requiring a revision of the maintenance program, rather than requiring individual repetitive actions and/or maintaining CDCCLs, requires operators to record AD compliance only at the time the revision is made. Repetitive actions and/or maintaining CDCCLs specified in the airworthiness limitations must be complied with in accordance with 14 CFR 91.403(c). Other FAA AD Provisions (n) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Information may be e-mailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.
