Narrative:
On gear retraction just after liftoff in atl, we had a complete 'a' system hydraulic failure. When we cranked the main gear, both mains cranked down normally. The so could not get the nose gear crank to turn on his first attempts to crank. He kept trying, even using his foot and leg for leverage. Finally the so got a little movement from the crank and after approximately 10 mins was able to free the gear and it locked down normally. The landing by the first officer was outstanding. The rollout was normal and uneventful. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a B727-200 and the hydraulic component that failed was unknown as maintenance did not give out any details. The reporter said the stiff nose gear manual extension was written up for correction.

Title: A B727-200 IMMEDIATELY AFTER TKOF AND GEAR RETRACTION EXPERIENCED COMPLETE LOSS OF 'A' SYS HYD PRESSURE AND QUANTITY. SO HAD DIFFICULT TIME CRANKING DOWN MANUAL NOSE GEAR EXTENSION.
Narrative: ON GEAR RETRACTION JUST AFTER LIFTOFF IN ATL, WE HAD A COMPLETE 'A' SYS HYD FAILURE. WHEN WE CRANKED THE MAIN GEAR, BOTH MAINS CRANKED DOWN NORMALLY. THE SO COULD NOT GET THE NOSE GEAR CRANK TO TURN ON HIS FIRST ATTEMPTS TO CRANK. HE KEPT TRYING, EVEN USING HIS FOOT AND LEG FOR LEVERAGE. FINALLY THE SO GOT A LITTLE MOVEMENT FROM THE CRANK AND AFTER APPROX 10 MINS WAS ABLE TO FREE THE GEAR AND IT LOCKED DOWN NORMALLY. THE LNDG BY THE FO WAS OUTSTANDING. THE ROLLOUT WAS NORMAL AND UNEVENTFUL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS A B727-200 AND THE HYD COMPONENT THAT FAILED WAS UNKNOWN AS MAINT DID NOT GIVE OUT ANY DETAILS. THE RPTR SAID THE STIFF NOSE GEAR MANUAL EXTENSION WAS WRITTEN UP FOR CORRECTION.
