Fatigue Investigation of the E-2B/C Nose Landing Gear
Abstract
A laboratory fatigue investigation was performed on an E-2B and an E- 2C nose landing gear to determine whether the authorized limit of 650 catapult launches could be extended. The starboard holdback lug of the E-2B nose landing gear, with modified drag brace attachment lugs, failed after the application of 3,336 test cycles. Using a test scatter factor of two, this is equivalent to 1, 668 service catapult launches. The outer cylinder of the E-2C shock strut assembly cracked under the packing nut after completion of 7,430 test cycles. Again, using a test scatter factor of two, this is equivalent to 3,715 service catapult launches.
