So there I was, capturing the glideslope for the ILS 03 with the needle centered and under the hood. My trusty PA32R-300 (Lance) taking me to the runway sight unseen. At one degree above glideslope my CFII has me drop the gear. Actuate the lever.....nothing. No gear intransit light. No change in feel from the gear now acting as a speed brake. Nothing. I look over at the CFII and say "did you pull my breaker?" I was thinking he was messing with me. "Nope." We start checking breakers. Nothing popped. Gear level back up. Gear lever back down. Nothing. (still on glideslope, mind you ) We break off the approach and point towards home. On the approach previous to this one, the nose gear green light hadn't lit until we went missed and then it locked in. Something was not working. As I pitched up to gain some altitude, and with the gear lever in the down position again, the gear finally dropped. Weird. We were about to go to the manual procedure but it went on its own. Any ideas on what could be happening? Do gear levers wear out? I mean everything wears out eventually (this is a 1977 model). I could imagine the nose gear thing could be from a spring wearing out, but this last one nothing was moving. That doesn't seem to be related....but what do I know? Mechanic will be called in the morning but I wouldn't be surprised if he can't look at it until next week.
