Narrative:
On the climbout I noticed my left hydraulic flow light start to flicker then remain steady. I pulled out the QRH and ran through the appropriate emergency checklist. I then proceeded to return to the airfield. As I was making the turn the right hydraulic flow light started to flicker then remained steady. As I was approaching [the departure airport] I ran the; 'gear will not extend hydraulically;' checklist. After pulling the emergency t-handle I did not get three green lights on the gear indicator. I cancelled my landing clearance and flew southbound to verify that I did everything correctly. As I was circling I continued to pull the emergency t-handle a couple of times to try to get the gear to blow down but the gear would not blow down. After trying a couple of times I made the determination that it wasn't going to come down so I proceeded to view the 'landing with a defective nose gear;' checklist. I informed [company operations] and ATC of the situation and that I would be performing a gear up landing. [Company operations center] then contacted me and per the on call duty manager requested that I hold a little bit longer before attempting the landing. As I continued the hold I pulled the emergency T handle one last time to get the gear to blow down and the gear blew down. I informed [company operations center] and ATC that I was able to blow the gear down and informed them that I was going to land. I landed and taxied to the terminal with no other incident.

Title: C402 pilot reported the loss of both hydraulics systems and a temporary failure of the emergency gear extension system.
Narrative: On the climbout I noticed my L HYD FLOW light start to flicker then remain steady. I pulled out the QRH and ran through the appropriate emergency checklist. I then proceeded to return to the airfield. As I was making the turn the R HYD FLOW light started to flicker then remained steady. As I was approaching [the departure airport] I ran the; 'Gear will not extend hydraulically;' checklist. After pulling the emergency T-Handle I did not get three green lights on the gear indicator. I cancelled my landing clearance and flew southbound to verify that I did everything correctly. As I was circling I continued to pull the emergency T-Handle a couple of times to try to get the gear to blow down but the gear would not blow down. After trying a couple of times I made the determination that it wasn't going to come down so I proceeded to view the 'Landing with a defective nose gear;' checklist.
