AD 2019-23-08 Airworthiness Directives; Saab AB, Saab Aeronautics (Formerly Known as Saab AB, Saab Aerosystems) Airplanes
Models named: SAAB 2000. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all Saab AB, Saab Aeronautics (formerly known as Saab AB, Saab Aerosystems) Model SAAB 2000 airplanes, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
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.
Unsafe condition
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 deteriorated capacity of the fuel probes, which could lead to incorrect fuel reading, possibly resulting in fuel starvation and uncommanded engine in-flight shutdown, and consequent reduced control of the airplane.
Affected ADs
This AD replaces AD 2019-03-19, Amendment 39-19571 (84 FR 6062, February 26, 2019) (“AD 2019-03-19”).
