Event Overview
A flight instructor (CFI) and an owner-pilot were conducting landing practice at Ranchaero Airport. The CFI was to provide instruction as needed while the pilot practiced landings, and also to familiarize himself with the pilot's airplane. The owner-pilot performed the first landing, the CFI performed the second, and the owner-pilot performed the third approach and attempted landing.
Approach and Landing
According to the CFI, the pilot's final approach was flown at a speed slightly higher than normal. The touchdown occurred nose wheel first, and during the rollout the airplane began porpoising—oscillating nose-up and nose-down. After the third or fourth oscillation, the CFI took over the controls and applied full engine power in an effort to stabilize the airplane and take off.
Go-Around and Impact
The CFI maintained control as the airplane became airborne and partially retracted the wing flaps. The airplane climbed, impacted several trees, and came to rest approximately one-quarter mile south of the airport. Neither the CFI nor the pilot reported any mechanical malfunction with the airplane during the flight.
Runway and Surroundings
Ranchaero's runway 15 is 2,280 feet long with a displaced landing threshold of 200 feet. Trees are located near both the approach and departure ends of the runway. Touch-and-go landings are prohibited on this runway.
Investigation Status
The accident investigation did not identify a probable cause. The source material notes no mechanical issues, and the pilots' actions are described without attribution of error or system failure.
