The tailstrike cracked open the aft pressure bulkhead. The telescope is mounted in the aft end of the fuselage behind a pressurized bulkhead. The aft belt terminated in a transverse bulkhead. Aft, it terminated at a seven-inch bulkhead. Installers also used screws set directly into the bulkhead and facing the fuel tank. For additional cargo security a removable floor to ceiling metal and mesh bulkhead is optional. This was fitted onto the bulkhead inside the engine bay. Both compartments were separated by a fireproof bulkhead. Slosh baffles are also mounted on this bulkhead. The joints with the torpedo bulkhead were weakened enough to cause leaking. The aging bulkhead and other dock structures at the marina were rebuilt. Behind the main belt was a torpedo bulkhead thick. During takeoff, cargo broke loose, causing damage to the bulkhead. The main belt was reinforced by a torpedo bulkhead that was thick. There was a arch over the steering gear closed by a 1-inch-thick forward bulkhead.
