Findings · 2
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot was concluding a personal flight. He stated that he lowered the landing gear while preparing to land and felt the airplane's drag increase; however, he could not remember if he got confirmation that the landing gear were down and locked from the indicator light in the cockpit. He stated that the landing flare was normal but that as the airplane continued the landing roll, all three landing gear collapsed. The airplane sustained structural damage to the fuselage. Postaccident examination of the airplane revealed that all the landing gear were in the gear wells. The main landing gear doors were not damaged and only the nose landing gear door had light scratches, which is likely due to the landing gear being in the retracted position as the airplane touched down on the runway. A landing gear swing was accomplished, and no mechanical malfunctions or failures were revealed that would have precluded normal operation.
Factual narrative
On September 26, 2017, at 1638 Pacific daylight time, a Piper PA-24-260 airplane, N9020P, sustained substantial damage during landing at Whiteman Airport, Los Angeles, California. The private pilot was not injured. The airplane was registered to and operated by the pilot as a Title 14 Code of Federal Regulations Part 91 personal flight. Visual meteorological conditions prevailed at the time of the accident and no flight plan had been filed for the flight which departed from Camarillo, California about 1600. The pilot reported that he lowered the landing gear while preparing to land on runway 12. He stated that after lowering the gear, he felt the airplane's drag increase but could not remember if he got a confirmation they were down and locked from the indicator light. He further stated the landing flare was normal and the airplane touched down on the main landing gear. Thereafter, the nose gear settled toward the runway and as the airplane continued on the landing roll, all three gear collapsed. The airplane incurred structural damage to the fuselage. A Federal Aviation Administration certified mechanic examined the airplane after the accident. He stated that all three landing gear were in the gear wells. The main landing gear doors were not damaged and only the nose landing gear door had light scratches, which he thought was consistent with the landing gear being retracted at the time of impact. After recovering the airplane, the mechanic swung the landing gear and performed an examination. He found no mechanical malfunctions or failures that would have prevented normal operation.
