The crew used the emergency pump handle to force the valve to the under carriage detent. Using the emergency hydraulic pump, manually extended the landing gear, the crew reentered lax traffic and landed without further incident. Maintenance personnel discovered hydraulic fluid leaking from the left wing fillet. Hydraulic line p/n 1379007D463 was chafed through the wall. The emergency selector valve p/n air 87360-1 was found to exhibit corrosion on the mated surfaces of the bobbin and valve housing. A safety recommendation to amend recurring AD 92-07-24 1800 hr. To 200 hrs. And to consider a new AD concerning hydraulic system fluid water and acid content criteria has been submitted. This incident report is considered closed.
