Airworthiness Directive · Amendment 39-14057 · BAE Systems (Operations) Limited (Jetstream) Model 4101 Airplanes
BAE Systems (Operations) Limited (Jetstream) Model 4101 Airplanes
This AD applies to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This AD requires replacing the aileron trim chain with a new, improved aileron trim chain, and modifying the installation of the aileron trim chain. This AD is prompted by a report that the aileron trim cables were connected incorrectly on a correctly installed aileron trim chain. We are issuing this AD to prevent incorrect connection of the aileron trim cables, which could result in failure of the aileron trim system and consequent reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 30 months after the effective date of this AD: Replace the aileron trim chain, part number (P/N) 14127003-401, with a new, improved aileron trim chain, P/N 14127003-403; and modify the installation of the aileron trim chain; according to the Accomplishment Instructions of BAE Systems (Operations) Limited Service Bulletin J41-27-061, Revision 1, dated July 12, 2002.
Replacements and modifications accomplished before the effective date of this AD according to BAE Systems (Operations) Limited Service Bulletin J41-27-061, dated November 7, 2001, are considered acceptable for compliance with the corresponding actions specified in this AD.
Although the service bulletin referenced in this AD specifies to report compliance information to the manufacturer, this AD does not include that requirement.
