Airworthiness Directive · Amendment 39-19403 · Landing gear
Fokker Services B.V. Airplanes
Superseded. A later AD replaced this one: AD 2020-04-12. Comply with the one in force.
This AD applies to Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes, certificated in any category, all manufacturer serial numbers, if equipped with Goodrich main landing gear (MLG).
We are adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This AD was prompted by a report of cracks, in various directions, in the lower portion of a main landing gear (MLG) piston. This AD requires a detailed visual inspection of the MLG, and replacement if necessary. We are issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD, do a detailed visual inspection of each MLG piston part number (P/N) 41141-5, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-32-169, dated August 23, 2017.
If any crack is found, during any inspection required by paragraph (g) of this AD, before further flight, replace the MLG piston with a serviceable piston (i.e., a new piston, a piston that has not accumulated any flight cycles since overhaul, or a piston that has been inspected as required by paragraph (g) of this AD and has no cracks), in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-32-169, dated August 23, 2017.
(1) Submit a report of the findings (both positive and negative) of the inspection required by paragraph (g) of this AD to Fokker Services B.V., Technical Services, fax: +31 (0)25-2627-211; email: technicalservices@fokker.com, at the applicable time specified in paragraph (i)(1)(i) or (i)(1)(ii) of this AD. The report must include the information specified in the questionnaire of Fokker Service Bulletin SBF100-32-169, dated August 23, 2017.
(i) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.
(ii) If the inspection was done before the effective date of this AD: Submit the report within 30 days after the effective date of this AD.
(2) Although Fokker Service Bulletin SBF100-32-169, dated August 23, 2017, specifies to submit certain information to Goodrich, this AD does not include that requirement.
As of the effective date of this AD, it is allowed to install a MLG piston P/N 41141-5, or a replacement MLG with a MLG piston P/N 41141-5, on any airplane, provided the MLG piston is new, or has not accumulated any flight cycles since overhaul, or has been inspected as required by paragraph (g) of this AD and has no cracks.
