However, he reported that he did not extend the landing gear prior to touchdown and the airplane landed with the landing gear retracted. The airplane sustained substantial damage to the left wing, left aileron and the bottom of the fuselage. The pilot reported that there were no mechanical failures or anomalies with the airplane prior to or during the flight that would have prevented normal flight operation. ## Factual narrative According to the pilot, after completing the maintenance test flight, he established a normal approach to the runway.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
