Bettsometer


A Bettsometer is a fabric degradation tester commonly used to measure or test the integrity of fabric coverings on aircraft and their wings.

Overview

The Bettsometer comprises a pen-like instrument and a smooth round needle or pin. The needle is inserted into the fabric and then the instrument is pulled to exert a specific force on the fabric in order to test. A visual inspection is made to check for any rips or tears at the needle insertion point.

Application

The Bettsometer test is often a requirement for the annual 'permit' renewal and is usually carried out by an aircraft inspector who will know the requirements of the test.
