BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes
This AD applies to the airplanes specified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category, having lift spoiler jacks with part number (P/N) P308-45-0002, P308-45-0102, or P308-45-0202.
(1) All BAE Systems (Operations) Limited Model BAe 146-100A, -200A, and -300A series airplanes.
(2) All Model Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A airplanes.
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ airplanes. This AD requires calculating the current life of each lift spoiler jack, and eventually replacing each lift spoiler jack. This AD results from a review of all system components as part of the life- extension program for the affected airplanes that indicated the fatigue life limit of certain lift spoiler jacks cannot be extended from the current life limit. We are issuing this AD to prevent failure of the lift spoiler jack, and consequent increased drag and uncommanded roll inputs, which could reduce the flightcrew's ability to control 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 18 months after the effective date of this AD: Calculate the current life of each lift spoiler jack in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Modification Service Bulletin ISB.27-178, dated January 14, 2005.
Note 1: BAE Systems (Operations) Limited Modification Service Bulletin ISB.27-178 refers to the service information listed in Table 1 of this AD as additional sources of service information for the actions in paragraphs (f) and (g) of this AD.

Within 18 months after the effective date of this AD or before the accumulation of 55,000 total flight cycles on the lift spoiler jack, whichever occurs later: Replace each P/N P308-45-0002, P308-45-0102, or P308-45-0202 lift spoiler jack with a serviceable unit, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Modification Service Bulletin ISB.27-178, dated January 14, 2005. Thereafter, replace each lift spoiler jack with a serviceable unit at intervals not to exceed 55,000 flight cycles.
