Contributing to the accident was the pilot’s delay in lowering the tail after landing. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Use of equip/info: use of equip/system](https://openairdocs.org/ntsb-findings/02063015): Personnel issues › Task performance · Pilot (probable cause); cases with it: [Boeing B75N1, 5 cases](https://openairdocs.org/ntsb-findings/02063015/cases.md?model=1380144), [All aircraft, 1,391 cases](https://openairdocs.org/ntsb-findings/02063015/cases.md) - [Action: delayed action](https://openairdocs.org/ntsb-findings/02041025): Personnel issues › Action/decision · Pilot (probable cause); cases with it: [Boeing B75N1, 1 case](https://openairdocs.org/ntsb-findings/02041025/cases.md?model=1380144), [All aircraft, 894 cases](https://openairdocs.org/ntsb-findings/02041025/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Landing-landing roll: Nose over/nose down](https://openairdocs.org/ntsb-events/096) (defining event); cases with it: [Boeing B75N1, 10 cases](https://openairdocs.org/ntsb-events/096/sequence.md?model=1380144), [All aircraft, 2,287 cases](https://openairdocs.org/ntsb-events/096/sequence.md) ## Analysis The pilot reported that he was landing the tailwheel-equipped airplane and that the landing roll was smooth as the tail came down. He indicated that there was then no rudder control and that the airplane veered left. He brought the control stick back and applied right brake. The propeller struck the runway and the airplane nosed over. The vertical tail and rudder sustained substantial damage during the noseover. The pilot reported that there were no mechanical malfunctions with the airplane during the flight and stated that he probably should have dropped the tail earlier in the landing roll to avoid the loss of rudder control. ## Factual narrative The pilot reported that he was landing and that the landing roll out was smooth as the tail came down.
