Narrative:

I made a full normal approach to landing runway 30 at the atlantic municipal airport, inclusive of normal deployment of the landing gear. On landing, nose gear failure became apparent when propeller impacted the centerline of runway 30. No personal injury occurred to pilot or passenger and no property damage occurred to any property other than the aircraft. 2 days later, upon request by flight standards for a copy of my airman certificate and medical certificate, I discovered both had become lost. I provided my airman certificate number, medical certificate number, and a copy of the registration for my medical certificate issued september, 2000. Callback conversation with reporter revealed the following information: the aircraft he was flying was of 1948 vintage, with only 1 light gear down indication! A maintenance check revealed the probable cause of the nose landing gear not extending was the result of a bent actuator rod which caught the gear door, inhibiting gear extension. This particular aircraft type has a 100 KTS, gear down, (door) speed restr. It's speculated that previous, unintentional exceeding of this speed may have caused some damage to the actuator rod causing it to fail/bend at a later date.

Original NASA ASRS Text

Title: A BE35 PLT, UPON LNDG AT AIO, EXPERIENCED COLLAPSE OF THE NOSE GEAR!

Narrative: I MADE A FULL NORMAL APCH TO LNDG RWY 30 AT THE ATLANTIC MUNICIPAL ARPT, INCLUSIVE OF NORMAL DEPLOYMENT OF THE LNDG GEAR. ON LNDG, NOSE GEAR FAILURE BECAME APPARENT WHEN PROP IMPACTED THE CTRLINE OF RWY 30. NO PERSONAL INJURY OCCURRED TO PLT OR PAX AND NO PROPERTY DAMAGE OCCURRED TO ANY PROPERTY OTHER THAN THE ACFT. 2 DAYS LATER, UPON REQUEST BY FLT STANDARDS FOR A COPY OF MY AIRMAN CERTIFICATE AND MEDICAL CERTIFICATE, I DISCOVERED BOTH HAD BECOME LOST. I PROVIDED MY AIRMAN CERTIFICATE NUMBER, MEDICAL CERTIFICATE NUMBER, AND A COPY OF THE REGISTRATION FOR MY MEDICAL CERTIFICATE ISSUED SEPTEMBER, 2000. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE ACFT HE WAS FLYING WAS OF 1948 VINTAGE, WITH ONLY 1 LIGHT GEAR DOWN INDICATION! A MAINT CHK REVEALED THE PROBABLE CAUSE OF THE NOSE LNDG GEAR NOT EXTENDING WAS THE RESULT OF A BENT ACTUATOR ROD WHICH CAUGHT THE GEAR DOOR, INHIBITING GEAR EXTENSION. THIS PARTICULAR ACFT TYPE HAS A 100 KTS, GEAR DOWN, (DOOR) SPD RESTR. IT'S SPECULATED THAT PREVIOUS, UNINTENTIONAL EXCEEDING OF THIS SPD MAY HAVE CAUSED SOME DAMAGE TO THE ACTUATOR ROD CAUSING IT TO FAIL/BEND AT A LATER DATE.
