Airworthiness Directive · Amendment 39-17038 · Hydraulic power
Saab AB, Saab Aerosystems Airplanes
This AD applies to Saab AB, Saab Aerosystems Model SAAB 2000 airplanes, certificated in any category; all serial numbers.
We are adopting a new airworthiness directive (AD) for all Saab AB, Saab Aerosystems Model SAAB 2000 airplanes. This AD was prompted by reports of hydraulic accumulator failure. This AD requires replacing certain hydraulic accumulators with stainless steel hydraulic accumulators, and structural modifications in the nose landing gear bay. We are issuing this AD to prevent failure of hydraulic accumulators, which may result in damage to the airplane and injury to occupants.
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 12 months after the effective date of this AD, replace all hydraulic accumulators having part number (P/N) 08 8423 030 1, with stainless steel hydraulic accumulators having P/N 40800-2050, and do the structural modifications in the nose landing gear bay, in accordance with the Accomplishment Instructions of Saab Service Bulletin 2000-29-024, Revision 01, dated November 5, 2010.
After replacing hydraulic accumulators having P/N 08 8423 030 1 with hydraulic accumulators having P/N 40800-2050, and doing the structural modifications in the nose landing gear bay, as required by paragraph (g) of this AD, no person may install any hydraulic accumulator having P/N 08 8423 030 1 on any airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
