Incident Summary
A pilot reported an event during landing where the aircraft exhibited a rapid descent and subsequent bounce, followed by violent porpoising. According to the pilot's statement, the approach was conducted at a speed of 70 knots. The stall horn did not activate during the approach. However, once the aircraft was over the pavement, it sank rapidly. The pilot added power to arrest the descent, but the aircraft bounced from an estimated height of 10 feet. The descent was then arrested with power, and a normal landing was made. Immediately thereafter, the aircraft began to porpoise violently, and the pilot was unable to stop the oscillations.
Pilot Statement
The pilot stated, "Although my approach speed was 70 knots and the stall horn never went off, the aircraft sank rapidly once I was over the pavement. I added power to arrest the descent but the aircraft bounced on the landing from approximately 10 feet. I arrested the descent with power and made a normal landing, however, the aircraft began to porpoise violently, and I was unable to stop it." She further noted that as a safety recommendation, she should have initiated a go-around after the first bounce.
Mechanical Status
No mechanical problems were reported by the pilot. The aircraft systems were functioning normally according to the pilot's account.
