DescriptionThe object of this report is to give a brief resume of tests made on the B-3A oleo shock absorbers and landing gear, and their results; and to enumerate the alterations and improvements of the design that were found necessary in order to bring the oleo up to test requirements. It was concluded that the alterations made by the Airplane Branch on the shock absorbing strut improved the action of the shock absorber. An improved condition was obtained for filling the oleo with oil and for determining the oil level in the cylinder, which is of importance from the service and maintenance point of view.
