Incident Overview
On June 22, 2007, at 15:33 UTC, a Boeing Stearman A75N1 (registration N62TS) suffered a runway excursion at Aeródromo Municipal Bissaya Barreto – Coimbra (LPCI). The aircraft was on a positioning flight to Viseu with a technical stop in Coimbra. During landing, the right wheel brake locked, causing the aircraft to veer uncontrolled onto the right runway edge before coming to a stop.
One person was on board; there were no injuries. The aircraft sustained no damage.
Aircraft Information
The aircraft was a 1940 Boeing Stearman A75N1 (serial number 75-971) equipped with a Pratt & Whitney R-1340-NA-1 engine (serial 42-10428) and a Hamilton Standard 12D40-211 propeller (serial A6881C). The pilot held a valid ATPL(A) license and was qualified to fly the type.
Investigation and Conclusion
The investigation determined that a technical malfunction—specifically, the locking of the right wheel brake—caused the runway excursion. As the aircraft was a museum piece and undamaged, it was released to maintenance services for repair of the fault before continuing its flight. No recommendations were issued.
