While practicing for my commercial certificate in a T-tail Piper Arrow IV, I put the gear down on downwind, and one green light didn't come on.
In the right seat was a CFII/Multi, who had over 1,000 hours but less than 10 hours in Pipers, whereas I had about 300 hours, and over 200 in Pipers, having done my PPL in stiff-legged Cherokees.
As a certificated pilot, I was PIC, but we talked about how to handle the emergency, and the CFI and I decided that since I had so much more experience in Pipers, I would handle the emergency tasks, while he handled the radios and looked for traffic.
We did the proverbial tower fly by (although they wouldn't say anything except the gear "appeared to be down"), and they cleared me to land on any runway. Our landing was uneventful, and it turned out to be an electrical MX issue.
When we landed, however, the flight school nearly fired the CFI for not having taken control of the aircraft during the emergency.
Did we make the right decision for me to handle the emergency? Or should I have let the CFI/CFII/MEI with over 1,000 take over as PIC and handle the airplane?
