British Aerospace (Jetstream) Model 4101 Airplanes
All Model Jetstream 4101 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 (c) 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 British Aerospace (Jetstream) Model 4101 airplanes, that requires a functional check of the rudder pedals to ensure full and free movement at all rudder pedal positions, and modification of the forward rudder pedal boxes. The actions specified by this AD are intended to prevent restricted movement of the rudder pedals due to structural interference, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
To prevent restricted movement of the rudder pedals due to structural interference, which could result in reduced controllability of the airplane, accomplish the following:
(a) Within 60 days after the effective date of this AD, perform a functional check of the left and right rudder pedals to ensure full and free movement at all rudder pedal positions, in accordance with Part 1 of the Accomplishment Instructions of Jetstream Alert Service Bulletin J41-A27-055, dated March 10, 2000. If any restriction in rudder pedal movement is found, prior to further flight, accomplish the modification required by paragraph (b) of this AD.
(b) Within 8 months after the effective date of this AD, modify the forward pedal boxes (including moving the rudder pedals and measuring clearances between the rod attachment bolt and the flange of the floor channel; correcting any incorrect clearances; and repeating the functional check of the rudder pedals specified in paragraph (a) of this AD) in accordance with Part 2 of the Accomplishment Instructions of Jetstream Alert Service Bulletin J41-A27-055, dated March 10, 2000.
