- [Landing: Landing gear not configured](https://openairdocs.org/ntsb-events/095) (defining event); cases with it: [Short Bros SD3-60, 3 cases](https://openairdocs.org/ntsb-events/095/sequence.md?model=8100606), [All aircraft, 584 cases](https://openairdocs.org/ntsb-events/095/sequence.md)

## Analysis

According to the operator, the flight crew was conducting one engine inoperative (OEI) training as part of a check ride. While conducting an OEI instrument landing system approach, the flight crew became task-saturated and “failed to complete the approach and final checklists.” The flight crew completed the landing to the runway with the landing gear fully retracted and the airplane sustained substantial damage to the fuselage. The flight crew reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
