Aircraft involved

Probable cause & findings

The pilot’s failure to maintain directional control during landing in gusting tailwind conditions.

Factual narrative

The pilot of the tailwheel-equipped airplane reported that, during final approach, the airplane required about 10 degrees of crab to the right to maintain alignment with the runway. During the landing flare, he reduced power to idle, slowly applied rudder to align the fuselage with the runway centerline, and added right aileron to counter the crosswind. He added that, during the 3-point landing, the airplane bounced. During the landing roll, he had full right aileron countering the wind when a "perceived" gust lifted the right wing. He held full right aileron, full aft yoke, and used the rudder to maintain alignment. Subsequently, about 40 knots groundspeed, the left main landing gear collapsed, and the left wing impacted the runway. The airplane sustained substantial damage to the left wing and aileron. The pilot reported that the left main landing gear detached from the airplane. The Federal Aviation Administration inspector reported that, the airplane had been in an accident in 1990 and repaired in 1995. He added that, the maintenance records show that the left gear and left wing (along with several other items) had been replaced during the 1995 repair. He also reported, the landing gear bolt was bent and the threads on the nut were stripped. The automated weather observation system located at the accident airport reported that, about 20 minutes before the accident, the wind was from 110° at 8 knots, gusting to 19 knots. The same observation system reported that, about 10 minutes after the accident, the wind was from 150° at 13 knots, gusting to 21 knots. The pilot landed on runway 4R.
