## Probable cause

The pilot’s failure to maintain a proper descent rate, which resulted in a hard landing.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Landing: Prop/jet/rotor blast/suction](https://openairdocs.org/ntsb-events/082) (defining event); cases with it: [Cessna 414, 1 case](https://openairdocs.org/ntsb-events/082/sequence.md?model=2075908), [All aircraft, 44 cases](https://openairdocs.org/ntsb-events/082/sequence.md)

## Analysis

The pilot reported that he was cleared to land on runway 30R, but when he turned to the base leg, he observed a large airplane on final for 30L. However, he continued the approach, and the landing flare was normal, but the airplane landed hard. He recalled that the airplane "seemed ok," and he taxied to parking. The following week, the airplane underwent an annual inspection. The inspection revealed that the left wing false spar and trunnion were substantially damaged. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

## Factual narrative

The pilot reported that he was cleared to land on runway 30 right, but when he turned base, he observed a large airplane on final for 30 left. However, he continued the approach, and during the landing the flare was normal, but the airplane landed hard. He recalled that the airplane "seemed ok" and he taxied to parking and shutdown. The following week, the airplane underwent an annual inspection. During the annual inspection the left wing false spar and trunnion required replacement. The airplane sustained substantial damage to the left wing false spar and trunnion. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

## Other investigations on N1652T (1)

From the NTSB's public API. 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.

- [NTSB CEN24LA329](https://openairdocs.org/ntsb/CEN24LA329), Jul 4, 2024: Cessna 414 (N1652T), Leadville, CO, substantial damage. Probable cause: A loss of brake fluid for reasons that could not be determined, which resulted in a loss of braking effectiveness during landing.
