AD 2012-22-05 Airworthiness Directives; Fokker Services B.V. Airplanes
Models named: F.28 Mark 0070, 0100. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
(1) This AD applies to Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes, certificated in any category, all serial numbers, equipped with Goodrich (formerly Menasco, Colt Industries) main landing gear (MLG) units, part numbers (P/N) 41050-7, 41050-8, 41050-9, 41050-10, 41050-11, 41050-12, 41050-13, 41050-14, 41050-15, 41050-16, 41060-1, 41060-2, 41060-3, 41060-4, 41060-5, or 41060-6. (2) This AD requires revisions to certain operator maintenance documents to include new actions (e.g., 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 actions, the operator may not be able to accomplish the actions 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 (AMOC) according to paragraph (m)(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.
Compliance
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Required actions
This paragraph restates the initial inspection required by paragraph (g) of AD 2011-04-01, Amendment 39-16601 (76 FR 8618, February 15, 2011). Within 30 days after March 22, 2011 (the effective date of AD 2011-04-01), do a detailed visual inspection for cracks of the MLG pistons, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-32-158, dated October 2, 2009.
Unsafe condition
This AD was prompted by a new modification developed to safeguard the integrity of the MLG assembly and improve surface protection of the affected area of the MLG piston. We are issuing this AD to prevent MLG failure, possibly resulting in loss of control of the airplane during the landing roll-out.
Affected ADs
This AD supersedes AD 2011-04-01, Amendment 39-16601 (76 FR 8618, February 15, 2011).
