Description of Driving Event:
The aft cavity bulkhead was built entirely outside the aircraft with no requirements to demonstrate the actual fit inside the aircraft. After manufacturing was complete, it was discovered that the aft bulkhead did not fit inside the aircraft. An investigation of this problem revealed that the dimensions on the drawings were incorrect. The aft bulkhead wall had to be removed and modified. This additional work cost the project a delay of about 3 weeks.
