Airworthiness Directive · Amendment 39-15432 · Fuel
Fokker Model F.28 Mark 0070, 0100, 1000, 2000, 3000, and 4000 Airplanes
Superseded. A later AD replaced this one: AD 2008-06-20 R1. Comply with the one in force.
This AD applies to Fokker Model F.28 Mark 0070 and 0100 airplanes, all serial numbers, certificated in any category; and Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes, serial numbers 11003 through 11241, 11991 and 11992, certificated in any category.
Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (g)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.
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 3 months after the effective date of this AD or before December 16, 2008, whichever occurs first, do the action in paragraph (f)(1)(i) or (f)(1)(ii) of this AD, as applicable. For all identified tasks, the initial compliance time starts from the effective date of this AD. The repetitive inspections must be accomplished thereafter at the intervals not to exceed those specified in Fokker 70/100 Fuel Airworthiness Limitation Items (ALI) and Critical Design Configuration Control Limitations (CDCCL) Report SE-672, Issue 2, dated December 1, 2006; or Fokker Service Bulletin SBF28-28-050, Revision 1, dated January 8, 2008; as applicable; except as provided by paragraphs (f)(3), (f)(4), and (g)(1) of this AD.
(i) For Model F.28 Mark 0070 and 0100 airplanes: Revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate the inspections, thresholds, and intervals specified in Fokker 70/100 Fuel Airworthiness Limitation Items (ALI) and Critical Design Configuration Control Limitations (CDCCL) Report SE-672, Issue 2, dated December 1, 2006.
(ii) For Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes: Incorporate into the FAA-approved maintenance inspection program the inspections, thresholds, and intervals specified in Fokker Service Bulletin SBF28-28-050, Revision 1, dated January 8, 2008.
(2) Within 3 months after the effective date of this AD or before December 16, 2008, whichever occurs first, do the action in paragraph (f)(2)(i) or (f)(2)(ii) of this AD, as applicable.
(i) For Model F.28 Mark 0070 and 0100 airplanes: Revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate the CDCCLs as defined in Fokker 70/100 Fuel Airworthiness Limitation Items (ALI) and Critical Design Configuration Control Limitations (CDCCL) Report SE-672, Issue 2, dated December 1, 2006, except for the CDCCL component titled “Level Control Pilot Valve Solenoid, jiffy junction.”
(ii) For Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes: Incorporate into the FAA-approved maintenance inspection program the CDCCLs as defined in Fokker Service Bulletin SBF28-28-050, Revision 1, dated January 8, 2008.
(3) Where Fokker 70/100 Fuel Airworthiness Limitation Items (ALI) and Critical Design Configuration Control Limitations (CDCCL) Report SE-672, Issue 2, dated December 1, 2006; and Fokker Service Bulletin SBF28-28-050, Revision 1, dated January 8, 2008; allow for exceptional short-term extensions, an exception is acceptable to the FAA if it is approved by the appropriate principal inspector in the FAA Flight Standards Certificate Holding District Office.
(4) After accomplishing the actions specified in paragraphs (f)(1) and (f)(2) of this AD, no alternative inspection, inspection interval, or CDCCL may be used, unless the inspection, interval, or CDCCL is part of a later revision of Fokker 70/100 Fuel Airworthiness Limitation Items (ALI) and Critical Design Configuration Control Limitations (CDCCL) Report SE-672, Issue 2, dated December 1, 2006; or Fokker Service Bulletin SBF28-28-050, Revision 1, dated January 8, 2008; as applicable; that is approved by the Manager, ANM-116, International Branch, Transport Airplane Directorate, FAA, or the European Aviation Safety Agency (EASA), or its delegated agent, or unless the inspection, interval, or CDCCL is approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (g)(1) of this AD.
(5) Actions done before the effective date of this AD in accordance with Fokker 70/100 Fuel Airworthiness Limitation Items (ALI) and Critical Design Configuration Control Limitations (CDCCL) Report SE-672, Issue 1, dated January 31, 2006; or Fokker Service Bulletin F28/28-050, dated June 30, 2006; are acceptable for compliance with the corresponding requirements of this AD.
Note 2: For Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes, after an operator complies with the requirements of paragraphs (f)(1)(ii) and (f)(2)(ii) of this AD, those paragraphs do not require that operators subsequently record accomplishment of those requirements each time an applicable action is accomplished according to that operator's FAA-approved maintenance inspection program.
Note 3: This AD differs from the MCAI and/or service information as follows: No differences.
