| Requirement: | Inspect the aerodynamic seal of the wing-to-fuselage fairings and the fuselage skin, and apply an improved sealing by means of a fillet seal in accordance with the Accomplishment Instructions of Fokker Services SBF100-53-107, dated26 February 2008, or later EASA approved revision.Note: EASA AD 2008-0079 refers. |
| Compliance: | Within 12 calendar months after 3 July 2008. |
| This Amendment becomes effective on 3 July 2008. | |
| Background: | Reports were received from Fokker 100 operators of flight crews experiencing in- flight difficulties with roll control. Investigation revealed that roll control difficulties were due to ice on the aileron pulleys that are installed on the centre wing spar and located in the main landing gear wheel bays. The actions required by this Directive were intended to prevent rainwater, wash-water, or de-icing fluid leaking onto the affected aileron pulleys.Amendment 1 is issued in response to a new EASA AD, which was prompted by new reports of problems due to moisture in the same affected area. This AD mandates a new service bulletin from Fokker Services which requires an additional one-time inspection and application of improved sealing. |
