Airworthiness Directive · Amendment 39-21020 · Equipment/furnishings
The Boeing Company Airplanes
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.
The FAA is adopting a new airworthiness directive (AD) for The Boeing Company Model 737-300, -400, and -700 series airplanes, modified to a Bedek Division Special Freighter (BDSF) by Supplemental Type Certificate (STC) ST01566LA, ST01961SE, or ST02556SE, with a 9G rigid barrier. An emergency AD was sent to all known U.S. owners and operators of these airplanes. This AD requires complying with loading restrictions and methods. 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. The FAA is issuing this AD to address the unsafe condition on these products.
Before further flight, comply with the loading restrictions and methods specified in the Accomplishment Instructions of Israel Aerospace Industries Service Bulletin 365-00-054, dated December 2019, except as specified in paragraph (h) of this AD. The loading restrictions include reducing the cargo weights for each loading configuration and using additional straps as applicable.
(1) Where Israel Aerospace Industries Service Bulletin 365-00-054, dated December 2019, specifies using cargo restraint straps rated at a minimum 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 airplane as provided in the existing airplane flight manual (AFM) can only be used if that cargo and all cargo aft of that location are restrained to a forward load factor of 9G.
