Airworthiness Directive · Amendment 39-16007 · Fokker Model F.28 Mark 0070 and 0100 Series Airplanes
Fokker Model F.28 Mark 0070 and 0100 Series Airplanes
This AD applies to Fokker Model F.28 Mark 0070 and 0100 series airplanes, certificated in any category, equipped with a downward-opening “airstair” type passenger door.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions:
(1) Within 500 flight cycles or 4 months after the effective date of this AD, whichever occurs first, install a new warning placard near the status lights of the panel of the door lock indication, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-11-025, Revision 1, dated December 13, 2007.
(2) Within 4,000 flight cycles after the effective date of this AD, do a one-time inspection of the clearance between lever P/N A26997-003 and the up-limit switch, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-52-086, dated November 1, 2007.
(3) If any clearance is found outside the range defined in Fokker Service Bulletin SBF100-52-086, dated November 1, 2007, during the inspection required by paragraph (f)(2) of this AD, before further flight, correct the clearance in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-52-086, dated November 1, 2007.
(4) If done before the effective date of this AD, installing the warning placard near the status lights of the panel of the door lock indication, in accordance with Fokker Service Bulletin SBF100-11-025, dated November 1, 2007, is acceptable for compliance with the requirements of paragraph (f)(1) of this AD.
(5) Modifying the airplane in accordance with Fokker Service Bulletin SBF100-52-044, Revision 1, dated November 1, 2007, terminates the requirements of paragraph (f)(2) of this AD.
Note 1: This AD differs from the MCAI and/or service information as follows: Note 1 of the “Compliance” section of European Aviation Safety Agency (EASA) Airworthiness Directive 2008-0020, dated January 28, 2008, states that any airplane that has not yet been modified in accordance with Fokker Service Bulletin SBF100-52-069, dated December 3, 2001, must be modified prior to or concurrently with paragraph (f)(1) of this AD. However, all U.S. airplanes have met this requirement with the issuance of AD 2006-03-07, amendment 39-14471; therefore, modification in accordance with Fokker Service Bulletin SBF100-52-069, dated December 3, 2001, is not applicable.
