During a training flight, a CFI allowed a student to continue a simulated engine-out landing despite concerns. The airplane landed hard, bounced, drifted left, and struck a VASI during the subsequent go-around.

Incident Overview

A training flight involving a simulated engine-out landing resulted in a hard landing and subsequent contact with a Visual Approach Slope Indicator (VASI) system. The certified flight instructor (CFI) had given the student pilot a simulated engine failure to practice a landing approach.

Sequence of Events

During the approach, the CFI assessed that the airplane would likely land short of the intended runway. However, the instructor elected to allow the student to continue the approach without intervention. The airplane subsequently touched down hard, causing it to bounce. After the bounce, the airplane began to drift left and started to settle. In response, the CFI added power for a go-around. During the go-around, the left landing gear and the stabilator struck a VASI unit located to the left of the runway.

Contributing Factors

The source does not provide any analysis or causal factors beyond the described sequence. The instructor's decision to let the student continue despite anticipating a short landing may have contributed to the outcome, but this is not stated explicitly in the source and is therefore not included.

Conclusion

The incident involved a hard landing, bounce, and subsequent strike of runway equipment during a training maneuver. No further details about damage, injuries, or other circumstances are available from the source.
