What to do
Operators of aircraft with GE Passport 20-17BB1A, 20-18BB1A, and 20-19BB1A engines must perform the required visual inspections before exceeding 30, 50, or 75 flight cycles after July 14, 2022, depending on engine cycles since new. Re-torque of the core compartment coupling nuts must be completed within 30 or 100 flight cycles after the effective date, depending on engine serial number. Any findings of fuel leakage, fire, or heat distress require immediate maintenance per FAA-approved instructions.
Summary
The document titled "Engine - Fuel Core Compartment - Inspection / Re-torque" is a Federal Aviation Administration (FAA) Airworthiness Directive (AD 2022-13-12) addressing all General Electric Company GE Passport 20-17BB1A, 20-18BB1A, and 20-19BB1A model turbofan engines. This AD mandates inspections and maintenance actions to prevent fuel leakage and potential engine fires. It applies specifically to these GE Passport turbofan engines installed on aircraft such as the Bombardier Global 7500.
What changed
This new AD introduces mandatory visual inspections of the core compartment, re-torqueing of core compartment coupling nuts, ground power assurance checks, and borescope inspections for the affected GE Passport engines. It requires operators to perform maintenance based on inspection results following FAA-approved instructions. Unlike the related GE service bulletins, this AD does not require reporting to the manufacturer or contacting GE field service engineers.
Why it matters
This AD is critical for aviation professionals because it addresses a safety risk involving fuel leaks that have already caused in-flight engine fires and shutdowns. Operators and maintenance organizations must comply to prevent engine failure, in-flight shutdown, and potential loss of aircraft control. Compliance ensures continued airworthiness and reduces the risk of costly incidents and emergency landings.
