Incident Overview
During a post-flight inspection conducted by the airplane operator's maintenance personnel, a rental/instructional airplane was discovered with substantial damage. The damage came to light after two pilots, each having flown the aircraft separately the previous day, reported discrepancies to maintenance.
First Pilot's Report
The first pilot reported a tire sidewall discrepancy noted during a preflight inspection. In response, maintenance personnel replaced the wheel assembly and returned the airplane to service without performing any further inspection. The pilot subsequently flew the airplane and returned it without noting any additional issues.
Second Pilot's Report
The second pilot reported a binding in the control column and difficulty reinstalling the gust lock during their preflight inspection. Following this report, maintenance personnel grounded the airplane for the day and, upon inspection, found damage to the airplane's firewall.
Maintenance Findings
The source does not specify the extent of the firewall damage or any other damage items beyond noting that the airplane sustained substantial damage. No further details regarding the exact nature of the control column binding or the gust lock issue were provided. The aircraft was retained by maintenance for further evaluation after the two discrepancy reports.
Investigation Status
The source does not state a probable cause for the damage, nor does it attribute the damage to any specific action or condition. No information about the aircraft type, registration, date, operator location, occupants, injuries, time of day, weather, or ATC involvement is given.
