AD 2008-03-21 Airworthiness Directives; Fokker 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 Model F.27 Mark 050 airplanes, certificated in any category; serial numbers 20103 through 20172 inclusive.

Unless already done, do the following actions. (1) Before the accumulation of 20,000 total flight cycles, or within 3 weeks after the effective date of this AD, whichever occurs later, perform a detailed visual inspection for cracks of the fuselage bottom skin chine line between fuselage station (STA) 6675 and STA 15375 in accordance with Part 3, Steps A. and B., of the Accomplishment Instructions of Fokker Service Bulletin SBF50-53-058, dated June 30, 2006. If any crack is found appearing through the paint layer, before further flight, remove the paint to determine the extent of the cracking and repair in accordance with the instructions in the service bulletin. (2) Before the accumulation of 45,000 total flight cycles, or within 3 weeks after the effective date of this AD, whichever occurs later, perform a detailed visual inspection for cracks of the fuselage bottom skin chine line between STA 1320 and STA 3100 in accordance with Part 3, Steps C. and D., of the Accomplishment Instructions of Fokker Service Bulletin SBF50-53-058, dated June 30, 2006. If any crack is found appearing through the paint layer, before further flight remove the paint to determine the extent of the cracking and repair in accordance with the instructions in the service bulletin. (3) In all cases, whether or not cracks were found and repaired in accordance with the requirements in paragraphs (f)(1) and (f)(2) of this AD: Within 1,000 flight cycles after the visual inspections required by paragraphs (f)(1) and (f)(2) of this AD or within 1,000 flight cycles after the effective date of this AD, whichever occurs later, do an eddy current inspection of the fuselage bottom skin chine line (between the same fuselage stations as covered by the visual inspection) in accordance with Part 3 of the Accomplishment Instructions of Fokker Service Bulletin SBF50-53-059, dated August 24, 2006. If any crack is found during any eddy-current inspection, repair before further flight in accordance with the instructions in the service bulletin. (4) If any crack is found as a result of any inspection requirement of this directive, within 30 days after the inspection or 30 days after the effective date of this AD, whichever occurs later, report all findings to the Type Certificate holder at the following address: Fokker Services B.V., Technical Services Dept., P.O. Box 231, 2150 AE Nieuw-Vennep, the Netherlands. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: Although the MCAI or service information allows flight with cracks of different lengths on the fuselage bottom skin chine line between certain fuselage stations, this AD requires accomplishing the applicable repair before further flight if any crack is found. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (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. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act, the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
