Propulsion system deliveries were completed with acceptance of the last spare lift fan. Fan speed VTOL and CTOL flight clearance was requested and granted for A/C number two. Lift fan and J85 spare parts were shipped to Edwards Air Force Base. Number one A/C completed modification and ground tests at NASA-Ames prior to full scale wind tunnel tests. Engineering design and analysis was completed for the higher loading in the exit louver actuation system. Both aircraft completed systems functional tests at San Diego. A/C number two was shipped to Edwards AFB to begin flight tests and A/C number one was shipped to NASA-Ames for wind tunnel testing. Nose wheel shimmy encountered during taxi tests causing aircraft damage. Nose gear redesign and successful dynamic and static tests were completed. A systems failure evaluation was conducted on the flight simulator to establish emergency procedures. A/C damage as a result of nose gear failure was corrected.
