Aeronautical Engineers, Inc. (AEI) has  announced that Saltillo, Mexico-based Aeronaves T.S.M. S.A. de C.V. (TSM) has ordered four additional AEI B737-400SF freighter conversions.

    This order follows the announcement of two more AEI B737-400SF freighter conversions ordered by TSM in early March. Upon completion of this order, TSM will operate a total of seven AEI B737-400SF freighter conversions.

    Production slots and aircraft MSNs for this order have yet to be announced, however, all modification labor will be performed by the authorised AEI Conversion Centner, Commercial Jet, in Dothan, Alabama.

    The company says that the B737-400SF remains a popular freighter product offering for AEI. Since program launch, the company has redelivered over 120 freighter conversions – seven of which were redelivered in 2020.

    AEI’s B737-400SF shall provide TSM with a “highly flexible” Ancra CLS capable of carrying multiple ULD’s including:

    • (10) 88”x125” ULDs in P1 to P10 and
    • (1) 53”x88”x64” Pallet or AEP/AEH or 60.4”x61.5” AKE/LD3 or 61.5”x88”x56”H AYY in P11

    This flexibility has been designed by AEI to allow cargo operators to “immediately adapt” to multiple ULD configurations at a moment’s notice.  When combined with “proven reliability”, the AEI Converted B737-400SF will allow TSM to keep their aircraft – “In the air, generating revenue”.
