Wonder what time of the day it was. Anyway, what little I know about certain Piper twins I'll spout out here, and stand to be corrected. Is it not the case that if the panel lights are on the landing gear green light often won't work (one green I think vs three)? (or simply doesn't work)?
We had a similar incident two years ago on approach to Rhodos in a Twin Comanche and I think I remember that being the explanation. We didn't require it at the time, but I hope our pilot knew where the gear crank handle was located!
Cheers!
