(a) EFFECTIVE DATE This Emergency Airworthiness Directive (AD) is effective upon receipt. (b) AFFECTED ADS None. (c) APPLICABILITY This AD applies to The Boeing Company Model 737-300, -400, and -700 series airplanes, certificated in any category, modified to a Bedek Division Special Freighter (BDSF) by supplemental type certificate (STC) ST01566LA, ST01961SE, or ST02556SE, with a 9G rigid barrier. (d) SUBJECT Air Transport Association (ATA) of America Code 25, Equipment/Furnish- ings. (e) UNSAFE CONDITION This AD was prompted by a review of the manufacturing process for the 9G rigid barrier installed on BDSF conversions that identified a manufacturing non-compliance. It has been found that the surface preparation before bonding was improperly done, which can affect the 9G rigid barrier’s strength characteristics. The FAA is issuing this AD to address potential failure of the 9G rigid barrier under certain emergency landing loads, which could injure occupants. (f) COMPLIANCE Comply with this AD within the compliance times specified, unless al- ready done. (g) LOADING RESTRICTIONS AND METHODS Before further flight, comply with the loading restrictions and methods specified in the Accomplishment Instructions of Israel Aero- space Industries Service Bulletin 365-00-054, dated December 2019, ex- cept as specified in paragraph (h) of this AD. The loading restric- tions include reducing the cargo weights for each loading configura- tion and using additional straps as applicable. (h) EXCEPTIONS TO SERVICE INFORMATION (1) Where Israel Aerospace Industries Service Bulletin 365-00-054, dated December 2019, specifies using cargo restraint straps rated at a mini- mum of 7,500 pounds, for this AD use technical standard order TSO-C172 cargo restraint straps; that TSO specifies a load rating of 5,000 pounds. (2) The provisions for restraining cargo directly to a pallet or the air- plane as provided in the existing airplane flight manual (AFM) can only be used if that cargo and all cargo aft of that location are re- strained to a forward load factor of 9G.
