A pilot reported that the left main landing gear would not lock down, leading to a gear-up landing. Investigation found the brake line had caught on the wheel well structure.

Incident Overview

A first pilot reported that during the landing gear extension sequence, the left main landing gear failed to achieve a down and locked status. Although the gear-down indicator light (green) illuminated, a visual inspection confirmed that the left main gear was not in the locked position. Multiple attempts by the flight crew to extend and lock the left main gear were unsuccessful.

Decision and Landing

After exhausting available procedures, the pilot elected to land the airplane with the landing gear retracted. The aircraft touched down and slid to a stop on its belly.

Postaccident Examination

A postaccident examination of the landing gear system revealed that the left main wheel brake line had become caught on the wheel well structure during the extension cycle. The brake line had rotated from its normal position, allowing it to catch on the airframe. This restriction prevented the left main landing gear from moving into its fully extended and locked configuration.

Probable cause

The left main wheel brake line caught on the wheel well structure during the extension cycle of the landing gear, restricting the movement of the left main landing gear.
