Fluorescent Penetrant Inspection

PMM performs FPI in accordance with the ASTM-E1417 standard practice for liquid penetrant testing and ASTM-E1220 standard practice for visible penetrant testing. This allows us to not only perform these inspections for aviation related purposes, but also for any general liquid penetrant inspection requirement. PMM can perform liquid penetrant inspections with penetrants level 2, 3 and level 4. Our equipment includes an approved hand held UV light and a calibrated UV & white light meter to ensure the inspections are performed under the correct circumstances. They also allow us to perform the required inspections in the field. These include, but are not limited to:  

• AD 94-05-05R1: Inspection of cylinder head rocker bosses (Continental Motors) 
• SB505B: Inspection of Crankshaft I.D. for Corrosion (Lycoming) 
• SI1285E: Non Destructive testing of Lycoming engine parts (Lycoming)
