The FAA has proposed a new Global 7500 airworthiness directive. The notice of proposed rulemaking was published in the Federal Register on 16 July 2026. It applies to certain Bombardier BD-700-2A12 airframes, the type certificate under which the Global 7500 is delivered.
The unsafe condition traces to a Bombardier manufacturing quality escape. A red protective film cover on the bottom face of the No. 1 and No. 2 secondary power distribution assemblies may not have been removed during production. The film blocks the cooling mesh on the units. Left in place, it impedes airflow, drives the SPDA outside normal operating conditions and can lead to unit failure.
The FAA said failure of an SPDA could result in the loss of any system, or combination of systems, powered by these units. The proposed rule requires an inspection of the affected assemblies for the presence of the protective film, and applicable corrective actions where it is found. The agency has adopted Transport Canada Civil Aviation MCAI 2025-01377-T as the mandatory continuing airworthiness information.
Comments on the proposal close on 31 August 2026. The docket is FAA-2026-7221. The rule would take effect a set interval after final publication in the Federal Register. Owner-facing scope is a targeted inspection rather than a hardware retrofit, and the corrective action is removal of the film where present.
The Global 7500 entered service in late 2018 on the BD-700-2A12 type certificate. This is the third BD-700-2A12 rule of the last two months. The FAA finalised an inspection AD on wing slat 2 cove rib 6 bracket fasteners on 10 July 2026, effective 14 August, and a Loctite modification on seat frames on 15 June 2026, effective 20 July. Each addresses a distinct unsafe condition.
