What happened
During a night training flight in rain, a Piper Seneca crew received a persistent “GEAR UNSAFE” warning with the gear down. They used the emergency extension procedure, conducted visual passes, and landed safely; maintenance later found a mispositioned squat-switch pin.
Why it matters: The incident highlights the importance of cockpit-ground teamwork, calm troubleshooting and maintenance follow-up during uncertain landing-gear indications.
