Test of Moisture Sealant of U-6A (L-20) Magnetos.
Abstract
The U. S. Army Aviation Center Maintenance Ship reported that an ignition spray was used successfully as a seal to prevent moisture in the magnetos. As a result, the U. S. Army Aviation and Surface Materiel Command requested that this compound be evaluated by the U. S. Army Aviation Test Board. An aerosol liquid spray was evaluated by personnel of the U. S. Army Aviation Test Board during the period 4 October 1962-2 April 1963. The original test directive required the utilization of one treated (liquid spray) and one untreated magneto on a U-6A Airplane during a 150-hour flight program. For approximately ninety flight hours, the airplane was flown with the treated and untreated magnetos, at which time the directive was revised to require the treatment of both magnetos. Sixty-six flight hours were subsequently accumulated on the test airplane with both magnetos treated. The aerosol liquid spray was applied by removing the magneto case cover and spraying the internal components. The following results were noted. No magneto fouling occurred during the test. No detrimental effects were noted on the magnetos or engine as a result of the spray.
