A CARDINAL RG PLT LANDED GEAR UP. NIGHT OP. GEAR UP LNDG. ERROR ADMITTED.

Narrative

I PRACTICED TKOFS AND LNDG DURING THE AFTERNOON AS WELL AS NDB PRACTICE. SINCE IT WAS A CLR DAY; I WAITED TILL DARK TO PRACTICE TKOFS AND LNDGS AT NIGHT IN THE PATTERN. ON THE DOWNWIND; BASE AND FINAL; I CONCENTRATED ON PROPER SPD AND ALT AND COMPLETED ALL CHKS FOR LNDG A CESSNA CARDINAL; BUT SOMEHOW DID NOT PUT DOWN THE LNDG GEAR. I AM FAMILIAR WITH AND HAVE USED THE GUMP PROC. I HAVE APPROX 565 HRS TOTAL TIME WITH APPROX 35 HRS IN COMPLEX ACFT. PERHAPS I NEED MORE NIGHT FLYING; HAVING FLOWN APPROX 18 HRS AT NIGHT. I ATTEND SAFETY SEMINARS (15 IN LAST FEW YRS) AND AM CURRENT WITH MY INST FLYING. ALSO PERHAPS TOO MUCH CONCENTRATION ON INSTS. IT IS DIFFICULT TO EXPLAIN THE MOMENTARY LAPSE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE ACFT SUFFERED MINIMAL DAMAGE TO THE AIRFRAME; JUST A FEW SCRAPED RIVETS. THE ENG HAD TO BE INSPECTED FOR SUDDEN ENG STOPPAGE. THE RPTR GUSHED WITH GRATITUDE WHEN THIS ANALYST SUGGESTED LEAVING THE LNDG GEAR DOWN IN THE TFC PATTERN IN A SINGLE PLT ACFT. HE WILL SUGGEST THIS AROUND HIS FBO. THE FAA REQUIRED THAT THE RPTR TAKE A CHK RIDE WITH AN INSTRUCTOR WHO FOUND NO FAULT WITH THE RPTR'S FLYING.
