Airworthiness Directive · Amendment 39-13369 · Titeflex Corporation
Titeflex Corporation
This AD applies to certain Titeflex Corporation hoses that are identified by Boeing part number (P/N), or for certain hoses, by Titeflex parts manufacturer approval (PMA) P/N in this AD. These hoses are used on, but not limited to, Boeing 737-300, -400, -500, - 600, -700, -700C, -800, and -900; 757-200 and -300; 767-200, -300, and -300F; and 747-400 airplanes.
The FAA is adopting a new airworthiness directive (AD) for certain Titeflex Corporation hoses installed on Boeing 737-300, -400, - 500, -600, -700, -700C, -800, -900, 747-400, 757-200, -300, 767-200, - 300, and -300F airplanes. This AD requires, within 24 months after the effective date of the AD, inspection of certain Titeflex Corporation hoses for proper date and paint code, replacement if necessary, and inspection for proper heat treatment of aluminum B-nuts, if necessary. This AD is prompted by certain Titeflex Corporation hoses discovered with incorrect heat treatment of B-nuts. We are issuing this AD to prevent fire extinguishing system and fuel system hose failure due to improperly heat treated aluminum B-nuts.
