Event Details
A pilot was practicing night takeoffs and landings. After completing four or five landings at a large, well-lit airport, he returned to his smaller home airport to practice crosswind landings. The pilot stated that the approach to landing seemed normal, but the touchdown was "harder and louder than what I considered normal."
Post-Flight Inspection
Following the flight, the pilot consulted a mechanic and inspected the airplane for damage. No unusual findings were noted during that inspection.
Subsequent Discovery
Later, during routine maintenance, damage was found that was attributed to the hard landing. The source does not specify the extent or type of damage.
