Gas turbine engine component particulate sampling apparatus, system and method

A particulate sample collector for collecting a particulate sample deposited on a surface of a gas turbine engine component, the particulate sample collector comprising:

• a collection media support comprising a support surface that supports a collection media between an inlet of the particulate sample collector and an exit of the particulate sample collector;
• wherein:
• the inlet is comprised within a hollow body;
• the inlet and exit are fluidically coupled;
• and
• the exit is comprised within the hollow body or
• the exit is comprised within the collection media support (60);
• wherein:
• an airflow carrying the particulate sample enters the particulate sample collector at the inlet;
• the collection media collects the particulate sample;
• the airflow exits the particulate sample collector at the exit;
• the exit of the particulate sample collector is connectable to a vacuum source, the vacuum source creating at least a partial vacuum within the hollow body such that the airflow and the particulate sample carried by the airflow enter the particulate sample collector via the inlet;
• a first seal is provided at a first interface between the hollow body and the collection media support;
• and
• a second seal is provided at a second interface between the exit of the particulate sample collector and the vacuum source.
