Airworthiness Directive · Amendment 39-19802 · Fuel
Saab AB, Saab Aeronautics (Formerly Known as Saab AB, Saab Aerosystems) Airplanes
This AD applies to all Saab AB, Saab Aeronautics (formerly known as Saab AB, Saab Aerosystems) Model SAAB 2000 airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2019-03- 19, which applied to all Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. AD 2019-03-19 required a functional check of certain fuel probes, and replacement with a serviceable part if necessary. This AD continues to require a functional check of certain fuel probes, and replacement with a serviceable part if necessary. This AD also revises the definition of a "serviceable part." This AD was prompted by reports that certain fuel probes indicated misleading fuel quantities on the engine indicating and crew alerting system (EICAS). The FAA is issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2019-03-19, with a new definition of a “serviceable part.”
(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, having been checked and found to be within the acceptable tolerances, in accordance with the Accomplishment Instructions of Saab Service Bulletin 2000-28-028, dated April 19, 2018, or received as serviceable following repair or overhaul.
Note 1 to paragraph (g)(2): The definition of a “serviceable part” has been changed as of the effective date of this AD. Operators who have already complied with the requirements of paragraph (i) of this AD before the effective date of this AD using the previous definition of a “serviceable part,” which was “an affected part that has accumulated less than 1,500 total flight hours or 12 months since first installation on an airplane,” do not need to redo the replacement specified in paragraph (i) of this AD using the new definition of a serviceable part.
This paragraph restates the requirements of paragraph (h) of AD 2019-03-19, with no changes. Within 1,500 flight hours or 12 months after April 2, 2019 (the effective date of AD 2019-03-19), 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.
This paragraph restates the requirements of paragraph (i) of AD 2019-03-19, with no changes. 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 existing Minimum Equipment List (MEL), 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)(ii) 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.
