FAA Airworthiness Directives for Boeing 787-8 Cargo Door Frames and Rolls-Royce Trent 7000 Series Engines

This opportunity involves proposed airworthiness directives from the Federal Aviation Administration (FAA) targeting Boeing 787-8 airplanes and Rolls-Royce Trent 7000 series engines. - Government Buyer: - Federal Aviation Administration (FAA), Department of Transportation - OEMs Mentioned: - Boeing (aircraft and cargo door split frames) - Rolls-Royce Deutschland Ltd & Co KG (Trent700072 and Trent700072C engines) - Products/Services Requested: - Inspection of large forward cargo door (LFCD) split frames on Boeing 787-8 for affected batch numbers - Replacement of LFCD split frames with new frames made of Ti-6Al-4V alloy if nonconforming material is found - Replacement kit includes all 5 LFCD split frames and complete hardware for the cargo door surround - Initial and repetitive borescope inspections of high-pressure turbine (HPT) blades on Rolls-Royce Trent700072 and Trent700072C engines - Replacement of HPT blade set if axial cracking is detected - Unique/Notable Requirements: - Inspections and replacements must follow Boeing Alert Requirements Bulletin B78781205SB53010600 RB, Issue 001 - Material for replacement split frames must be Ti-6Al-4V alloy - Safety concerns include potential structural failure and impeded egress during rapid cabin decompression - The directive affects four U.S.-registered Boeing 787-8 airplanes - No specific part numbers provided; kit includes all 5 split frames - Rolls-Royce directive supersedes previous requirements, focusing on axial cracking in HPT blades - Estimated contract value: - Inspection and replacement costs are estimated but not explicitly stated; likely range is $50,000–$500,000 per aircraft depending on scope

Description

The FAA proposes a new airworthiness directive for certain Boeing Model 787-8 airplanes due to concerns that large forward cargo door (LFCD) split frames may have been manufactured with nonconforming material. The directive requires inspection of the LFCD split frames for affected batch numbers and applicable on-condition actions, including replacement with frames made of the specified Ti-6Al-4V alloy material. This action addresses the unsafe condition that could lead to structural failure and potential injury or impeded egress during rapid cabin decompression. Comments on the proposal must be received by October 5, 2026.
