Airworthiness Directive · Amendment 39-15067 · Fokker Model F.28 Mark 0070 and 0100 Airplanes
Fokker Model F.28 Mark 0070 and 0100 Airplanes
This AD applies to all Fokker Model F.28 Mark 0070 and 0100 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires a detailed inspection for wear of the attachment holes of the control levers of the braking system and applicable corrective actions. This AD results from a report that, after landing, the flightcrew of a Model F.28 Mark 0100 airplane noted that an extreme difference in pedal angle was required to achieve equal braking action. We are issuing this AD to prevent failure of one or more brake control levers, which could result in uncommanded braking and loss of control of the airplane during takeoff, landing, or taxiing.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 1,500 flight cycles or 12 months after the effective date of this AD, whichever occurs first: Perform a detailed inspection for excessive wear of the brake control levers and do the applicable corrective actions in accordance with and at the times specified in Section 3, “Accomplishment Instructions,” of Fokker Service Bulletin SBF100-32-142, dated August 12, 2005. Repeat the requirements of this paragraph thereafter for any replacement control lever at intervals not to exceed 12,000 flight hours after the installation of such a control lever. Operators should note that, where the service bulletin specifies immediate replacement of the control lever if the applicable remaining material (dimension X2) of the attachment hole is less than 2.0 millimeters (0.08 inch), this AD requires replacing the control lever if dimension X2 is less than or equal to 2.0 millimeters.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
