Probable cause

the circuit breaker for the hydraulic pump popped during gear extension which resulting in the failure of the landing gear to lock in the extended position.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Gear down and locked - not attainedPilot in command

Analysis

The pilot extended the landing gear 3 to 4 miles prior to landing. During the landing flare the landing gear warning horn sounded. The pilot reported that it was too late to initiate a go-around so he continued the landing during which the landing gear collapsed. Postaccident testing of the landing gear system revealed the hydraulic pump circuit breaker would pop when the landing gear was extended. This resulted in the gear being in a trailing unlocked position.

Factual narrative

On October 1, 1997, at 0830 central daylight time, a Cessna T210N, N5168A, operated by a commercial pilot collided with the terrain when the landing gear collapsed on touchdown. The landing was being made on runway 17 at the Hector International Airport, Fargo, North Dakota. The 14 CFR Part 91 flight was operating in visual meteorological conditions without a flight plan. The pilot was not injured. The airplane was substantially damaged. The flight originated from a private airstrip in Hillsboro, North Dakota, at 0800.

The pilot reported he extended the landing gear 3 to 4 miles prior to touchdown at an airspeed of 120 knots. He reported that he kept his hand on the gear lever until it was down at which time he made a visual check to assure it was down. He reported that during the landing flare he heard the gear warning horn; however, it was too late to initiate a go-around. The landing gear collapsed as the airplane touched down.

Post accident testing of the landing gear system revealed the hydraulic pump circuit breaker would pop when the landing gear was extended leaving the gear in a trailing unlocked position.
