Piper PA-28R-200 Cherokee Arrow II, G-GYMM
The pilot made an initial approach to Runway 03 but decided to go-around after seeing vehicles moving close to the runway. He then repositioned for an approach to Runway 21. During this second approach he heard an alarm, which he associated with a low throttle position. Its function is in fact to alert the pilot that the landing gear is up and it will sound when power is reduced significantly with the landing gear retracted. He advanced the throttle slightly, believing this would silence the alarm, but when it did not, he assumed the switch had malfunctioned and continued with the approach. Shortly before touching down he suddenly realised that the landing gear was up and selected it down, but too late to prevent the aircraft from landing wheels up.
