Incident Overview
An airplane sustained substantial damage following a hard landing. The pilot reported that after flying for approximately one hour, he returned to the airport to perform three night stop-and-go landings. During the first landing rollout, the pilot felt the landing gear begin to shimmy. He proceeded with a second stop-and-go landing, during which he again felt the landing gear shimmy during the rollout. After the second landing, he taxied back to the ramp and shut down the airplane.
Inspection Findings
The pilot conducted a visual inspection of the nose wheel and observed no apparent damage. However, a subsequent detailed inspection of the airplane revealed that the firewall was buckled and a flat spot was present on the rim of the nose wheel. The fixed-base operator reported that maintenance had been performed on the airplane prior to the flight, and at that time no damage was noted to the firewall or the nose wheel.
Conclusion
The hard landing resulted in substantial damage to the airplane, specifically a buckled firewall and a flat spot on the nose wheel rim. The pilot reported gear shimmy during the landings, but no further causal factors are provided in the source.
