During take-off, the pilot felt and heard a thump during rotation. The aircraft would not pressurize, and lost the utility hydraulic fluid. An aircraft on a subsequent take-off reported what appeared to be landing gear debris on the runway. After circling for one hour to burn off fuel, and conducting a tower fly by, the aircraft landed without the nosewheel gear on a foamed runway.
During rotation the nose gear separated. As the aircraft passed over it the belly of the aircraft was damaged. Take-off was completed and an emergency landing was conducted with the main gear and the stub of the nose gear shock strut extended.
Disassembly of the shock strut inner cylinder revealed the absence of several parts. The area where these parts are located is a sealed area that was not compromised. This discrepancy allowed a retention nut to back off which resulted in nose gear separation. The nose gear assembly was overhauled on 9 April 1985.
Improper overhaul of the nose gear assembly by other maintenance personnel.
