Incident Overview
During a landing at an airport, a pilot experienced a runway overrun after choosing to land with a tailwind. The pilot had listened to the airport weather report prior to landing, which indicated a slight tailwind on runway 22, the runway in use by other traffic. Despite this, the pilot opted to land on runway 22 rather than switching to a runway that would provide a headwind.
Pilot Account
In a phone conversation, the pilot stated that he landed "within the first couple hundred feet" of the runway at approximately 85 knots with full flaps deployed. During the landing roll, the airplane overran the runway, exiting the end and coming to rest on a 45-degree downslope. The pilot acknowledged that he "underestimated" the length of the runway, attributing this to the airplane being near its maximum gross weight and the presence of a slight tailwind.
Weather and Runway Details
According to the Avalon aviation weather report, the wind at the time of the accident was from 020 degrees at 5 knots. The Southwest U.S. Airport/Facility Directory lists runway 04/22 as 3,000 feet long. The first 2,000 feet of runway 22 have an upslope of 1.8%, while the remaining portion is level.
Performance Calculations
At maximum gross weight under the prevailing weather conditions, the airplane had a calculated ground roll of about 1,250 feet and a total landing distance of about 2,500 feet. When accounting for the 5-knot tailwind and the 1.69% upslope (as calculated), the final ground roll was estimated to be approximately 1,300 feet, with a total landing distance of about 2,650 feet.
Damage
The airplane sustained substantial damage to the right aft main wing spar.
