Narrative:

Nose gear collapsed on landing. About 40 KT wind, 10-20 degrees, to left on runway 30. Propeller strike, no injuries. Callback conversation with reporter revealed the following information: the reporter stated he was flying an A-36 beechcraft bonanza which he has owned and flown for the past 23 yrs. He has a total of 2500 hours and 2300 hours in this very airplane. The reporter is a neurosurgeon. When he first got the airplane, he raised the gear instead of the flaps on landing rollout. Also, he had an engine fail on takeoff about 20 yrs ago. Other than those 2 historic experiences, he has had no problems. He gets regular pilot recurrent training to keep his instrument rating valid. He did not seem sure what caused the loss of control. He said he did not feel the fact he had only flown 5 hours in the last 90 days was a factor. He said he did not know what his airspeed was on final. He had no idea. He was judging his speed by looking outside. He said he feels a mistake was putting flaps down just before touchdown. He does not believe he touched down nosewheel first but he did porpoise about 3 times before knocking the nose gear off. The friend he was visiting had called his home in south california suggesting he not attempt to come up because of the strong winds, but, the reporter had already left. Since the incident, he has gotten remedial training. Now he is very conscious of a 1.3 vso airspeed and does fly a final that provides a definite flare for a landing rather than a flat final with little or no flare.

Title: RPTR COLLAPSES NOSE GEAR ON LNDG PORPOISE.

Narrative: NOSE GEAR COLLAPSED ON LNDG. ABOUT 40 KT WIND, 10-20 DEGS, TO L ON RWY 30. PROP STRIKE, NO INJURIES. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED HE WAS FLYING AN A-36 BEECHCRAFT BONANZA WHICH HE HAS OWNED AND FLOWN FOR THE PAST 23 YRS. HE HAS A TOTAL OF 2500 HRS AND 2300 HRS IN THIS VERY AIRPLANE. THE RPTR IS A NEUROSURGEON. WHEN HE FIRST GOT THE AIRPLANE, HE RAISED THE GEAR INSTEAD OF THE FLAPS ON LNDG ROLLOUT. ALSO, HE HAD AN ENG FAIL ON TKOF ABOUT 20 YRS AGO. OTHER THAN THOSE 2 HISTORIC EXPERIENCES, HE HAS HAD NO PROBS. HE GETS REGULAR PLT RECURRENT TRAINING TO KEEP HIS INST RATING VALID. HE DID NOT SEEM SURE WHAT CAUSED THE LOSS OF CTL. HE SAID HE DID NOT FEEL THE FACT HE HAD ONLY FLOWN 5 HRS IN THE LAST 90 DAYS WAS A FACTOR. HE SAID HE DID NOT KNOW WHAT HIS AIRSPD WAS ON FINAL. HE HAD NO IDEA. HE WAS JUDGING HIS SPD BY LOOKING OUTSIDE. HE SAID HE FEELS A MISTAKE WAS PUTTING FLAPS DOWN JUST BEFORE TOUCHDOWN. HE DOES NOT BELIEVE HE TOUCHED DOWN NOSEWHEEL FIRST BUT HE DID PORPOISE ABOUT 3 TIMES BEFORE KNOCKING THE NOSE GEAR OFF. THE FRIEND HE WAS VISITING HAD CALLED HIS HOME IN S CALIFORNIA SUGGESTING HE NOT ATTEMPT TO COME UP BECAUSE OF THE STRONG WINDS, BUT, THE RPTR HAD ALREADY LEFT. SINCE THE INCIDENT, HE HAS GOTTEN REMEDIAL TRAINING. NOW HE IS VERY CONSCIOUS OF A 1.3 VSO AIRSPD AND DOES FLY A FINAL THAT PROVIDES A DEFINITE FLARE FOR A LNDG RATHER THAN A FLAT FINAL WITH LITTLE OR NO FLARE.
