Airworthiness Directive · Amendment 39-11944 · Fokker Model F.28 Mark 0100 Series Airplanes
Fokker Model F.28 Mark 0100 Series Airplanes
Superseded. A later AD replaced this one: AD 2001-20-05. Comply with the one in force.
All Model F.28 Mark 0100 airplanes, certificated in any category.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD), applicable to all Fokker Model F.28 Mark 0100 series airplanes, that requires replacement of the anti-skid control boxes with improved units. This action is necessary to prevent electromagnetic interference with the anti-skid control system, which could result in reduced brake pressure during low-speed taxiing, and consequent reduced controllability and performance of the airplane. This action is intended to address the identified unsafe condition.
To prevent electromagnetic interference with the anti-skid control system, which could result in reduced brake pressure during low-speed taxiing, and consequent reduced controllability and performance of the airplane, accomplish the following:
(a) Within 36 months after the effective date of this AD, replace any anti-skid control box having part number (P/N) 6004272-3, -4, or -5 with an improved anti-skid control box having P/N 6004272-6, in accordance with Fokker Service Bulletin SBF100-32-117, dated September 27, 1999.
