Detección de fugas en la aviación mediante detección de fugas por fluorescencia

Fugas de combustible en los aviones

Typical Process for Finding Leaks

Finding and fixing aircraft fuel tank leaks has always been an arduous and time-consuming process, many times best left to a specialist. Generally, the aircraft is pulled from service and parked in a hangar or designated safe area.

The general area of the leak is marked; the tank defueled, opened, vented and allowed to dry. A trained AMT dresses in anti-static clothing and ensures that the tank environment meets safety standards before entering the tank. Once inside, the area in question is located, sealant removed, and fasteners replaced if necessary. Safety is of highest importance, so the worked-on area is cleaned thoroughly and prepare for the reseal.

Next, the sealant is allowed to dry, and openings are closed. The tank is pressurized with shop air and the suspected area is sprayed with a soap solution. The soap solution is used to look for the telltale bubbles coming from a leak. If bubbles do appear, the process is repeated, and oversized fasteners are installed and/or another round of sealant is applied. If no bubbles appear, the tank is refueled and put on watch for leaks. If no leaks appear, the aircraft can be returned to service.

Soluciones de detección de fugas en la aviación de Spectronics

Spectronics produces Aero-Brite Tinte universal fluorescente para la detección de fugas que puede utilizarse para localizar fugas en todos los sistemas de fluidos de aviación de base petrolífera y sintética. El Aero-Brite es "seguro de usar en sistemas de combustible, hidráulicos y de lubricación de aeronaves" y "seguro de usar en motores de turbina y alternativos". El uso del Aero-Brite para la detección de fugas es de lo más sencillo. Se añade una cantidad prescrita de tinte fluorescente al sistema de fluido con fugas y se deja circular.

It can be used under all normal operating conditions and temperatures. When the mixture escapes at the leak site, it glows a bright fluorescent yellow-green color when illuminated with a Spectroline high-intensity UV inspection lamp. Aero-Brite comes in different sized containers and works with violet or ultraviolet flashlights to easily to check for leaks in those hard-to-get-to places.

According to Sales Experts, Spectroline aviation leak detection kit would be a better solution for specialty shops and crews needing a more robust system. They suggest that “using the fluorescent leak detection products will help decrease the number of aircraft grounded for repair work.” As a tip to AMTs using Aero-Brite, the company recommends that “wherever possible, leak sites should be scanned with the UV lamp under low ambient light conditions in order to enhance the fluorescent response of the dye.”
