## Analysis

THE PLT SAID THAT HE MADE A 'FAIRLY RAPID DESCENT' FROM A 10,500 FT MSL CRUISE ALT TO THE AIRPORT PATTERN AND EXPERIENCED A 'PAINFUL PRESSURE' IN HIS EARS. THE PLT SAID HE WAS ALSO WEARING A HEADSET. ON ENTRY INTO THE PATTERN, THEPLT SAID HE 'FORGOT TO LOWER THE LANDING GEAR' AND BELIEVES THAT, DUE TO BOTH THE 'PAINFUL EAR PRESSURE' AND THE MUFFLING EFFECT OF THE HEADSET, THE GEAR WARNING HORN WAS SOUNDING BUT ALL HE HEARD WAS A 'FAINT BACKGROUND PULSE THAT (HE) DISMISSED AS RADIO NOISE OF SOME KIND.'

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
