Airworthiness Directive · Amendment 39-19571 · Fuel
Saab AB, Saab Aeronautics (Formerly Known as Saab AB, Saab Aerosystems) Airplanes
Superseded. A later AD replaced this one: AD 2019-23-08. Comply with the one in force.
This AD applies to all Saab AB, Saab Aeronautics (formerly known as Saab AB, Saab Aerosystems) Model SAAB 2000 airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. This AD was prompted by reports that certain fuel probes indicated misleading fuel quantities on the engine indicating and crew alerting system (EICAS). This AD requires a functional check of certain fuel probes, and replacement with a serviceable part if necessary. We are issuing this AD to address the unsafe condition on these products.
(1) An affected part is a fuel probe having part number (P/N) 20136-0101, P/N 20136-0102, P/N 20136-0103, P/N 20136-0104, P/N 20136-0105, or P/N 20136-0106; with fuel low level sensors having P/N 20137-0101.
(2) A serviceable part is an affected part that has accumulated less than 1,500 total flight hours or 12 months since first installation on an airplane.
Within 1,500 flight hours or 12 months after the effective date of this AD, whichever occurs first, accomplish a functional check of the fuel indicator gauging accuracy and the low level warning, in accordance with the Accomplishment Instructions of Saab Service Bulletin 2000-28-028, dated April 19, 2018.
If the functional check required by paragraph (h) of this AD is found to be out of tolerance, within the limits and under the applicable conditions, as specified in the operator's Minimum Equipment List, replace the affected part with a serviceable part, in accordance with the Accomplishment Instructions of Saab Service Bulletin 2000-28-028, dated April 19, 2018.
As of the effective date of this AD, no person may install, on any airplane, an affected part, unless it is a serviceable part, as defined in paragraph (g)(2) of this AD.
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.
