 Any advice for a fixing the nose gear door actuator cylinder seal which blew
 yesterday.
 
 How long to replace the seal do you think.
 
 Just wondering if it is worth completely replacing the whole assembly by the
 time I get the $8 seals out here, and then the cost of shipping, running the
 actuator up to the maintenance outfit and back, who have the equipment and
 expertise to replace the seals, hourly rates $60.  Reckon its cost effective
 to buy the whole assembly and replace it myself.
 
 Thanks
