Airworthiness Directive · Amendment 39-14353 · Aerospatiale Model ATR42 and ATR72 Airplanes
Aerospatiale Model ATR42 and ATR72 Airplanes
This AD applies to all Aerospatiale Model ATR42-200, -300, -320, and -500 airplanes, and Model ATR72-101, -201, -102, -202, -211, -212, and -212A airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Aerospatiale Model ATR42 and ATR72 airplanes. This AD requires a one- time inspection to determine the part number or markings of the fuel quality indicator (FQI) and replacement of any FQI having an incorrect part number. This AD results from a report that an FQI having an incorrect part number was installed on a Model ATR72 airplane. We are issuing this AD to ensure that a correct FQI is installed. An incorrect FQI could result in fuel starvation to the engine and consequent engine shutdown during flight.
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 7 days after the effective date of this AD, do the inspection specified in paragraph (f)(1) or (f)(2) of this AD.
(1) Perform an inspection to determine the part number (P/N) of the fuel quantity indicator (FQI) 3QT, in accordance with ATR All Operators Message (AOM) 42-72/2005/08, issue 5, dated September 7, 2005. Instead of the inspection, a review of the airplane maintenance records is acceptable if the P/N of the FQI can be positively determined from that review.
(2) Inspect the faceplate of the FQI to verify that it has the correct markings as specified in paragraphs (f)(2)(i) and (f)(2)(ii), as applicable.
(i) For Model ATR42-200, -300, -320, and -500 airplanes: The FQI has the marking of 4960 lbs on the faceplate as illustrated in ATR AOM 42-72/2005/08, issue 5, dated September 7, 2005.
(ii) For Model ATR72-101, -201, -102, -202, -211, -212, and -212A airplanes: The FQI has the marking of 5500 lbs on the faceplate as illustrated in the AOM 42-72/2005/08, issue 5, dated September 7, 2005.
(g) If it can be positively determined, during the inspection required by paragraph (f) of this AD, that the FQI has the correct part number or marking, no further action is required by this AD.
(h) If it is determined, during the inspection required by paragraph (f) of this AD, that the FQI does not have the correct part number or marking, before further flight, install the FQI having the correct part number as specified in ATR AOM 42-72/2005/08, issue 5, dated September 7, 2005.
