Q&A:

  • The ATR-500 has a lot of erratic fuel indication in fuel quantity indicators. Is ATR aware and are these occurrences being monitored? Is there any guidance?

    ATR will review the FQI system component reliability for 2024 and update operators accordingly. In the meantime, ATR encourages all operators to implement a fuel policy within their operations.

  • We use anti-ice additive (FSII) on ATRs during winter season as otherwise we have noticed that these problems arise probably due ice in FQIs.

    It is recommended to use Fuel System Icing Inhibitors (FSII) in the service letter “extreme cold weather operations”.

  • Fuel system is Very critical.  Shouldn’t you redesign the system so to be more reliable?

    ATR will review the FQI system component reliability for 2024 and update operators accordingly. In the meantime, ATR encourages all operators to implement a fuel policy within their operations.

  • ATR is having many problems in FQI, even a brand new aircraft after EIS within one month. How are we addressing it?

    ATR issued the AOM 2023/04 issue 1 related to quality escape on fuel probes in June 2023.
    With the publication of this AOM ATR completed the actions related to the fuel probes quality escapes generating the FUEL MISMATCH alarm on 42-600 and fuel quantity misreading on all models of ATR 42.
    This AOM follows the publication of the related ATR SB ATR42-28-0050 and SAO VSB766048-28-001, recommending to inspect and replace the affected fuel probes.

  • Why ATR doesn’t write the fuel policy in the FCOM?

    The FCOM update to incorporate the fuel policy is in progress via APQ 4616.

  • What about the fuel mismatch on ATR42? It is sometimes spurious.

    ATR published the service letter ATR42-28-5005-00 “fuel mismatch alert”. This Service Letter informs operators that spurious FUEL MISMATCH alert could be experienced during the transition from climb to cruise level, on ATR42 only.

  • What is the tolerance of the FQI?

    The accuracy on the total fuel indication is described in the FCOM DSC 28.1.

  • How about use of anti-icing additives as safety barrier in winter conditions. This is not mandatory as stated by ATR. 

    It is recommended to use Fuel System Icing Inhibitors (FSII) in the service letters ATR72 SL_30_6011 and ATR42 SL_30_5018 “Extreme cold weather operations”.
