EASA AD US-2023-20-08
Magnetic Chip Detector Probe Tip - Inspection
Summary
The Federal Aviation Administration's Airworthiness Directive 2023-20-08 addresses certain General Electric Company CF6-80C2 series engines installed on aircraft such as the Boeing 767-300. This directive mandates inspection of the magnetic chip detector probe tip for metallic particles due to improperly installed bearings that could lead to engine fire. The AD aims to prevent unsafe conditions resulting from bearing failure in these engines.
What Changed
This new airworthiness directive introduces mandatory inspections of the magnetic chip detector probe tip on specified GE CF6-80C2 engine models for metallic particles covering more than 10 percent of the probe tip. If metallic particles are found, the engine must be removed from service. The AD is issued as an immediate safety measure following incidents of uncontained engine fire linked to bearing misinstallation.
Why It Matters
This AD is critical for aviation professionals as it addresses a safety risk that could lead to engine fires and damage to aircraft. Operators and maintenance teams must ensure compliance to avoid in-flight engine shutdowns and potential accidents. The directive also highlights the importance of proper bearing installation and monitoring through magnetic chip detector inspections.
What To Do
Operators of aircraft with affected GE CF6-80C2 engines must inspect the magnetic chip detector probe tip for metallic particles by October 19, 2023. If metallic particles covering more than 10 percent of the probe tip are detected, the engine must be removed from service immediately. Comments on the AD can be submitted to the FAA by November 20, 2023.
