Mobile vacuum procedure replaces cabin pressure tests

September 1, 2016 – Lufthansa Technik has developed a mobile procedure that allows even the smallest leaks around aircraft cabin doors and windows to be located. The Vacuum Leak Check allows in-flight pressure differences to be simulated in a procedure that will replace the company’s existing time-consuming process of activating the cabin pressurization system.

The windows and doors to be examined are closed during the vacuum leak check and covered from the outside by a special textile fiber as well as an airtight latex film with hose fittings. Air is then pumped out from between the latex film and the fuselage to create a vacuum. Even the smallest leaks can be localized precisely in the interior of the cabin by means of a leak detector.

“The new vacuum procedure excludes the possibility of other error sources and reduces process times significantly. The ground times of the respective aircraft are consequently also shortened. Moreover, less working time is needed and therefore costs reduced as only two instead of four employees are required to carry out the work,” stated Stefan Mehler, innovation project manager for aircraft maintenance at Lufthansa Technik.
