Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

A hard landing which exceeded the design stress limits of the aircraft.

Analysis

During landing from a visual approach at the conclusion of an IFR cross-country flight, the touchdown was hard and the aircraft was in a crab. The right main landing gear tire blew out on touchdown and damage was incurred to the right main landing gear assembly, right main landing gear brake system, right propeller, and the right fuselage wall was penetrated by debris.

Factual narrative

On December 21, 2000, at 1522 mountain standard time, a Mitsubishi MU-2B-60, received substantial damage during a hard landing at Aspen, Colorado. The commercial pilot and his two passengers were not injured. The flight was operating under Title 14 CFR Part 91 and an IFR flight plan was filed. Visual meteorological conditions prevailed for this cross-country flight, which departed McCook, Nebraska, at 1349.

According to observers at the Aspen airport, runway 15 was in use and the aircraft landed hard in a crab. The right main landing gear tire blew out on touchdown, damaging the right main landing gear brake system, right main landing gear assembly, right propeller, and the right side of the fuselage was penetrated by pieces from the blown tire.

In his narrative concerning the accident, the pilot said the right man tire blew out at touchdown and he stopped the aircraft on the runway and conducted an evacuation.
