Airworthiness Directive · Amendment 39-18332 · Fuselage
Fokker Services B.V. Airplanes
This AD applies to Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes, certificated in any category, all serial numbers.
We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This AD was prompted by reports that cracks can occur in a frame of the tail section on certain airplanes. This AD requires a one-time detailed inspection of the oblique frame 67-2 for any cracking, and repair if necessary. We are issuing this AD to detect and correct such cracking, which could lead to failure of the oblique frame 67-2, and consequent loss of the structural integrity of the tail section.
For airplanes that have accumulated more than 29,000 total flight cycles since the airplane's first flight as of the effective date of this AD: Within 500 flight cycles or 12 months after the effective date of this AD, whichever occurs first, do a one-time detailed inspection of the oblique frame 67-2 for any cracking, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-53-124, dated January 23, 2014. 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.
If any cracking is found during the inspection required by paragraph (g) of this AD, before further flight, repair the oblique frame 67-2, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-53-125, Revision 1, dated February 13, 2014.
