Airworthiness Directive · Amendment 39-19198 · Landing gear
Fokker Services B.V. Airplanes
This AD applies to Fokker Services B.V. Model F28 Mark 0100 airplanes, certificated in any category, serial numbers 11244 through 11481 inclusive, if maintenance records show that the airplane is in a post-Fokker Service Bulletin SBF100-32-107 configuration.
We are adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F28 Mark 0100 airplanes. This AD was prompted by a report that a jammed control cable prevented the full extension of the nose landing gear (LG). This AD requires a general visual inspection of the LG handle teleflex cable conduit connector for the presence of a grease nipple, a maintenance records check of affected airplanes, a detailed inspection for corrosion and damage of the LG handle teleflex cable, and corrective actions if necessary. This AD also requires revising the maintenance or inspection program, as applicable. We are issuing this AD to address the unsafe condition on these products.
Within 3 months after the effective date of this AD: Do a general visual inspection of the LG handle teleflex cable conduit connector for the presence of a grease nipple, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-32-167, dated December 14, 2016.
If, during the inspection required by paragraph (g) of this AD, a grease nipple is not found installed: Within 3 months after the effective date of this AD, check the maintenance records of the affected airplane for the previous 3 months for reports of an erratic or hard-to-move LG handle, and check the maintenance records to determine the date of the most recent installation, or inspection/lubrication, as applicable, of the LG handle teleflex cable.
Based on results of the maintenance records check required by paragraph (h) of this AD: Within the applicable compliance times specified in Table 1 to paragraph (i) of this AD, do a detailed inspection for corrosion and damage of the LG handle teleflex cable, replace the LG handle teleflex cable if any corrosion or damage is found, and lubricate the LG handle teleflex cable, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-32-167, dated December 14, 2016.

Within 6 months after the effective date of this AD: Revise the maintenance or inspection program, as applicable, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-32-167, dated December 14, 2016, to incorporate the applicable tasks and associated thresholds and intervals, based on the airplane configuration (pre- or post-SBF100-32-107) determined in the inspection required by paragraph (g) of this AD.
Within 3 months after the effective date of this AD, or within 30 days after doing the inspection required by paragraph (g) or (h) of this AD, whichever occurs later: Report the findings of the inspection specified in paragraph (g) of this AD, and the records check specified in paragraph (h) of this AD, to Fokker Services B.V., in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-32-167, dated December 14, 2016.
