NTSB narrative
The pilot took off following maintenance on the airplane, which did not involve the left main landing gear. The pilot planned to remain in the local traffic pattern. When the pilot attempted to extend the landing gear for landing, the left main gear remained retracted in the wheel well. The pilot reported that, although he followed the specified emergency gear extension procedure, the left main landing gear did not extend, so he landed with the gear up. The landing caused abrasion to the airframe belly skin and damage to the forward bulkhead as the airplane slid to a stop on the runway. An examination of the airplane revealed that the left main landing gear's brake line was mispositioned and had been caught on the gear leg's snubber in the wheel well. This interference between the brake line and the snubber precluded the gear from extending. The investigation did not determine the reason for the brake line becoming mispositioned in such a manner that its clearance from the snubber was inadequate.
Probable cause
Inadequate clearance between a landing gear brake system line and airframe components, which precluded gear extension and resulted in an intentional gear-up landing.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2010-04-11.
